In the world of ecommerce, inventory is typically a business’s greatest asset. You want to have enough of it so that you can meet demand but not so much that you can’t sell through it.

Purchasing inventory or raw materials isn’t always so simple. Not only do you need to find a manufacturer that sells the right supplies at the right price but also one that allows you to order an optimal amount of units.

Many manufacturers institute a minimum order quantity (MOQ) to get you to commit to buying enough so they can be cost-effective in production and make a profit. It’s why you buy a dozen eggs at once rather than a single egg at a time.

However, your ideal unit count or reorder quantity may not match your manufacturer’s MOQ, which is one of the joys of running an ecommerce business.

Of course, the suppliers you work with may change over time, as will your production runs. Your first 20,000 units may look very different from the inventory of your 1 millionth unit — not just in terms of the physical product itself but your cash flow, profitability, and financial health.

In this article, we’ll give an overview of minimum order quantity, take a look at some vital factors to consider when calculating MOQ requirements, and provide tips on how to make the most of MOQs.

What is minimum order quantity (MOQ)?

M inimum order quantity is the fewest number of units a business wants to sell to a customer at one time. In ecommerce, it’s most often used by a manufacturer or supplier in the context of a production run, though a merchant can put MOQs in place for different types of orders.

A couple examples:

How to calculate minimum order quantity in 4 steps

There is no one right MOQ amount, as many businesses have different requirements. Of course, there is often a tradeoff between having a higher MOQ or paying a higher price per unit. While there isn’t a go-to formula for calculating minimum order quantity, you can use the steps below as a starting point.

1. Determine demand

As a merchant purchasing inventory, demand forecasting takes product type, competition, seasonality, and other factors into account in estimating how many units you will sell. This data can help inform your next purchase order. Inventory forecasting goes hand in hand, to match supply with demand in this equation.

A few tips on monitoring demand especially during volatile times:

2. Calculate your break-even point

If you’re trying to establish a minimum order quantity of your own, you’ll need to know your break-even point. This may happen on the second transaction for DTC orders, when you recover the customer acquisition cost and your customer comes back through email marketing efforts.

For wholesale relationships, consider what the lowest per-unit dollar amount you’re willing to charge in exchange for a higher order value. It can’t be so low that your profit margins are next to nothing, but volume discounts are expected if you’re not just paying for smaller quantities at a higher price.

3. Understand your holding costs

Some products are more expensive to store than others (due to size, duration of storage, and special warehousing requirements). It’s financially beneficial to ensure such items are not kept in your inventory for too long.

Your inventory holding cost is the true cost of storing all of your products and something you must consider before investing too heavily in inventory.

4. Come up with your MOQ

Let’s say that you consistently have relatively high demand. Your partners purchase 200 units per order on average, and you need to sell at least 150 units per order to be profitable.

If your partners or customers have been willing to buy 200-unit orders in the past, you could set 200 units per orders as your minimum order quantity, or even go down to 150.

How to make the most of minimum order quantities

MOQ terms may seem awful when you’re on the purchasing side but awesome when you’re on the selling side. Many ecommerce businesses work with manufacturers that have minimum order quantity requirements in place, and some brands will be in the position of implementing their own MOQs through wholesale partnerships or minimum spend thresholds.

No matter where you are, here are some tips on how to work with MOQs.

Incentivize a higher spend on your orders

If you’re getting into wholesale or retail, you can require MOQs for bulk buyers to help ensure retailers pay you a minimum amount. In exchange for a minimum spend, you may choose to offer order volume discounts, where you charge the retailer less per unit in exchange for a higher guaranteed overall spend.

Also, you can adjust the prices to help incentivize higher spend. To do this, you need to set MOQ based on volume or cost. For low-cost items, you need to set a higher MOQ. This ensures you make a profit. For higher-cost items, having lower MOQ works, as the items are already more expensive. Following this strategy helps you make a profit no matter if you sell small or large quantities.

You can also try this with a free shipping minimum spend threshold, where you require customers to spend a certain amount of money to qualify for free shipping.

Eliminate slow-moving SKUs

Oftentimes, brands will have more SKUs than they should, and they’ll be stuck paying for storage and doling out cash to fulfill MOQs for products that don’t sell or drive revenue.

Keeping your SKU count simple and minimal helps with inventory forecasting. The difference between 20 and 40 SKUs can be hard enough to manage, let alone managing up to 400 SKUs. It’s easy to overestimate the use of new colors and slight variations in products. A lot of the time for ecommerce store experiences, having more than three options is too much to think about.

“Don’t go crazy with your SKU count. Focus on keeping a catalog small while still being able to increase lifetime value and new sales. For a lot of brands, 3 SKUs make up 50% of sales. You probably don’t need hundreds of products that aren’t driving revenue.”

Ryan Treft, Founder & Partner of Coalatree and Peejamas

Boost inventory turnover

Ordering excess inventory incentivizes you to have a higher inventory turnover ratio, meaning there’s pressure to sell your inventory quicker because you invested more cash upfront. This doesn’t mean only run flash sales to deplete inventory but seek out creative ways to attract and retain customers.

If the minimum order quantity amount is too high and you haven’t proven out your business model or product-market fit yet, it’s best to look elsewhere. Otherwise, you’ll have spent too much money that you may not be able to recover, while also paying for warehousing.

Find other suppliers or distributors

If your manufacturer has a higher MOQ than you’d like, you can always attempt to negotiate with them. There’s no harm in trying! If the manufacturer doesn’t budge and still requires an MOQ that’s too high for you, consider working with a trading company or wholesale distributor, the middlemen who buy in bulk from a manufacturer and resell smaller quantities to others.

Ask other questions

You’re allowed to get creative in your conversations with manufacturers and suppliers. Try rephrasing questions or thinking outside the box:

Focus on relationships

It’s possible to start with good terms from a manufacturer, but it becomes even easier over time especially when you build a good relationship with them.

Here’s how it works:

“Manufacturers want you to succeed. The last thing they want is for you to go out of business. If you’re not going through inventory or selling it, they have no motivation to help you. Sell the vision of your company, let them see the potential, your creative marketing, and how you’re differentiated. If they believe in your brand, they are not just your supplier, but a partner.”

3. Wholesale shipping capabilities

With ShipBob, online store owners can create and manage wholesale orders entirely from one central dashboard. While ShipBob primarily specializes in DTC fulfillment, its B2B fulfillment capabilities are expanding more over time.

Conclusion

One of the biggest barriers to starting a business is the capital required to get up and running. A minimum order quantity may prevent some businesses from working with a manufacturer altogether, but an MOQ can often be better in the long run for some brands rather than buying a smaller batch of inventory at a higher per-unit cost (when you factor in the higher average cost over time as well as freight costs to account for the higher frequency of reorders).

The best minimum order quantity will vary across businesses, and determining the right benchmark requires a lot of research, thoughtful sales planning, and luck. Finding an MOQ that works for you can help you scale your business while keeping it profitable.

Minimum order quantity FAQs

Ecommerce store owners have many questions regarding minimum order quantity requirements, and rightfully so. We’ve provided answers below to some common FAQs.

1. How do you find the minimum order quantity?

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

There is no standard formula for calculating minimum order quantity. To determine the right MOQ for your business, it’s worth forecasting demand, doing scenario planning, calculating volume discounts, and inventory carrying costs. You can then decide the lowest quantity that works for your business.

2. When should minimum order quantities be applied?

If you are a manufacturer who needs to produce products, then enforcing MOQ terms is important to stabilize your profit margin and make it worthwhile to produce in the first place. Ecommerce businesses that supply products typically sold in sets, such as kitchenware, should also have minimum order quotas through packaging or bundling to increase average order value, and they could also explore MOQs for wholesale partners.

3. What is MOQ in the supply chain?

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

In the ecommerce supply chain, MOQ is the minimum number of units of a single SKU that a business must purchase from a manufacturer or seller in one production run or purchase order.

4. What is the difference between MOQ and EOQ?

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

Economic order quantity (EOQ) is an equation used to determine the ideal quantity of inventory to stock in your warehouse so that you don’t spend too much on storage but also don’t run out of products. MOQ is the amount of product a supplier or seller requires a purchaser to buy at one time. An MOQ can cause an ecommerce business to purchase more inventory than they need at one time, causing them to be nowhere near their EOQ.

SQL Order of Operations

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

SQL is not a traditional programming language in which you write a sequence of instructions in a given order of execution. Instead, SQL is a «declarative» language, which means that by writing a SQL query, you declare what data you expect as a result of the query, but you don’t indicate how to obtain it.

Six Operations to Order: SELECT, FROM, WHERE, GROUP BY, HAVING, and ORDER BY

By using examples, we will explain the execution order of the six most common operations or pieces in an SQL query. Because the database executes query components in a specific order, it’s helpful for the developer to know this order. It’s similar to following a recipe: you need to know the ingredients and what to do with ingredients, but you also need to know in which order do the tasks. If the database follows a different order of operations, the performance of the query can decrease dramatically.

The best way to learn SQL order of operations is through practice. I recommend LearnSQL.com’s SQL Practice track. It contains over 600 hands-on exercises to practice your SQL skills. Or select the best course for you from over 30 interactive SQL courses we offer at various levels of proficiency.

The Employee Database

In this article, we will work with a database for a typical company that has employees distributed in different departments. Each employee has an ID, a name, and a salary and belongs to a department, as we can see in the following tables.

Sample of the EMPLOYEE table:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES

Sample of the DEPARTMENT table:

DEPT_NAMEMANAGERBUDGET
ACCOUNTING100300,000
IT101250,000
SALES104700,000

In this article, we will also use frequent SQL queries used in a company: «Obtain the names of employees working for the IT department» or «Obtain the number of employees in each department with a salary higher than 80.000.» For each of these queries, we will analyze the order of execution of its components.

Let’s start with a simple query to obtain the names of the employees in the IT department:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES
EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
101MarySexton82,000IT
103AgnesMiller95,000IT
FIRST_NAMELAST_NAME
MarySexton
AgnesMiller

Changes in the Order of Operations If We Add ORDER BY

Suppose your boss receives a report based on the query in the previous example and rejects it, because the employee names are not in alphabetical order. To fix it, you need to add an ORDER BY clause to the previous query:

FIRST_NAMELAST_NAME
AgnesMiller
MarySexton

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

Adding GROUP BY and HAVING Clauses to the Query

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES
EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES

Third, GROUP BY is applied, generating one record for each distinct value in the GROUP BY columns. In our example, we create one record for each distinct value in DEPARTMENT :

DEPARTMENT
ACCOUNTING
IT
SALES
DEPARTMENTCOUNT(*)
ACCOUNTING1
IT2
SALES1

Finally, we apply the ORDER BY clause, producing the final result of the query:

DEPARTMENTCOUNT(*)
IT2
ACCOUNTING1
SALES1

The order of execution in this example is:

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

Suppose we now want to obtain all the departments, except the SALES department, with an average salary higher than 80,000. The query for this situation is:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES

Second, the WHERE clause, excluding the SALES records, is processed:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT

Third, GROUP BY is applied, generating the following records:

DEPARTMENTAVG(SALARY)
ACCOUNTING79,250
IT88,500

Fourth, HAVING AVG(SALARY) > 80000 is applied to filter the group of records generated by GROUP BY :

DEPARTMENTAVG(SALARY)
IT88,500

Finally, the SELECT clause is applied, producing the final result of the query:

DEPARTMENT
IT

The order of execution in this example is:

Adding a New Operation: The JOIN Clause

The previous examples dealt with one table. Let’s add a second table using the JOIN clause. Suppose we want to obtain the last names and employee IDs of employees working for departments with a budget higher than 275,000. The query for this situation is:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENT
100JamesSmith78,000ACCOUNTING
101MarySexton82,000IT
102ChunYen80,500ACCOUNTING
103AgnesMiller95,000IT
104DmitryKomer120,000SALES

Second, we apply the JOIN clause generating a new intermediate result combining both tables:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENTDEPT_NAMEMANAGERBUDGET
100JamesSmith78,000ACCOUNTINGACCOUNTING100300,000
101MarySexton82,000ITIT101250,000
102ChunYen80,500ACCOUNTINGACCOUNTING100300,000
103AgnesMiller95,000ITIT101250,000
104DmitryKomer120,000SALESSALES104700,000

Third, WHERE BUDGET > 275000 is applied:

EMPLOYEE_IDFIRST_NAMELAST_NAMESALARYDEPARTMENTDEPT_NAMEMANAGERBUDGET
100JamesSmith78,000ACCOUNTINGACCOUNTING100300,000
102ChunYen80,500ACCOUNTINGACCOUNTING100300,000
104DmitryKomer120,000SALESSALES104700,000

Finally, SELECT EMPLOYEE_ID, LAST_NAME is executed, producing the final result of the query:

EMPLOYEE_IDLAST_NAME
100Smith
102Yen
104Komer

The order of execution in this example is:

Closing Words

In this article, we covered the execution order in SQL queries through examples. From these examples, we can see that there is an order of execution, but this order may vary depending on which clauses are present in the query. As a general guideline, the order of execution is:

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

However, if one of these clauses is not present, the order of execution will be different. SQL is an easy, entry-level language, but once you are inside, there are a lot of exciting concepts to explore.

Анкета на британcкую визу 2022

Получив кучу вопросов к статье про самостоятельное получение английской визы, я решила открыть анкету и заполнить её от начала до конца. Ниже вы увидите практически все возможные комбинации вопросов из анкеты и мои комментарии к ним.

How many do you want to order. Смотреть фото How many do you want to order. Смотреть картинку How many do you want to order. Картинка про How many do you want to order. Фото How many do you want to order

Где взять анкету на визу?

Анкета заполняется on-line. Для дипломатов; официальных лиц; членов семей тех, кому виза не нужна; бизнесменов и военных, отправляющихся на туманный альбион по работе или учёбе, предусмотрен отдельный вход. Про оформление этих виз я ничего не знаю. Читайте соотвествующие рекомендации на сайте.

Если вы турист-обыкновенный (что я и подразумеваю), то смело переходим на сайт визовой службы и ищем там зелёную кнопку

На следующай странице вам предложат выбрать язык. Я советую выбирать английский.

К сожалению, анкета не переведена полностью, а там, где переведена… в общем, лучше не надо. Если вы сомневаетесь в уровне своего владения языком, то гораздо удобнее будет воспользоваться переводчиком, встроенным в браузер, чем продираться через смесь языков с ошибками в переводе.

Ниже в вопросах из анкеты и комментариях к ним я буду использовать английскую формулировку со своим переводом, если он нужен.

Если вы выбрали русский, то на сдедующей странице не забудьте указать, что хотите видеть вопросы на двух языках.

И, последнее замечание: какой бы язык вы не выбрали, все ответы должны быть на английском.

Транскрибирование вашего имени и фамилии уже выполнено официальными лицами в вашем загранпаспорте. Срисуйте его оттуда без ошибок. Перевод адреса ул. Кржижановского д. 38 a стр. 5 кв. 4 на латиницу остаётся на ваше усмотрение. Гугл в помощь, но если вы ошибётесь, то это не конец света.

Анкета заполняется на английском языке

Enter the country in which you are making your application and wish to provide your biometrics

В введите страну, в которой вы подаёте заявку и хотите пройти биометрию. Выбираем Russian Federation.

В связи с пандемией короновируса вам предлагается сначала проверить, можете ли вы подать документы в выбранной стране и подтвердить то, что вы это сделали.

Выбираем I have checked available biometric enrolment locations and can travel to a location in my selected country. If no location is available in that country, then I confirm that I can travel to a location in the redirected country.

Как только формальности устранены наступает очень важный этап: регистрация.

Email address

Введите действующий e-mail, придумайте пароль (запишите на всякий случай) и обязательно дождитесь подтверждающего письма. Это очень важно, потому что попасть в свою анкету вы сможете только по ссылке. Эта ссылка у каждой анкеты своя. Её можно получить в регистрационном письме и при сохранении анкеты по ссылке Return to this application later (Вернуться к заявлению позже).

Если вы ошиблись, вводя e-mail, то исправить его можно только на этом этапе: If your email is wrong, click here to change it. В дальнейшем вы можете попытаться это сделать через службу поддержки и внезапно, это платная услуга даже если вы связываетесь с ними по электронной почте.

После ввода e-mail дождитесь письма и только после этого начинайте заполнять анкету

Who does this email address belong to?

Кому принадлежит этот электронный адрес? Подтвердите, что это ваш e-mail (или укажите, что не ваш, если вы заполняете анкету за кого-то другого), укажите второй e-mail, если хотите, и переходите к заполнению анкеты.

Provide your telephone number

Вводим телефоный номер с международным кодом, т.е. +79998887766

Where do you use this telephone number?

Здесь нужно выбрать, где вы доступны по этому номеру. Первая галочка — в Великобритании, вторая — за её пределами.

Если вы не используете этот номер в поездке, выбирайте только вторую.

Select whether this is your home, mobile or work telephone number

Укажите, что это за номер: домашний, рабочий или мобильный. Обычно это мобильный, значит, последняя галка.

Do you have any other telephone numbers?

Если вы хотите поделиться другими своими номерами, то выбирайте «Yes» и вводите их. Я считаю, что одного достаточно.

Are you able to be contacted by telephone?

Нужно выбрать, как с вами связаться по указанному телефону:

Если вы выбираете что-то, кроме первого пункта, вас попросят объяснить, почему. Например, люди, имеющие проблемы со слухом, вряд ли могут общаться по телефону кроме как по SMS: I have hearing problem.

Enter your name, as shown in your current passport or travel document

Given name(s) — Имя и отчество.

Other family name — Фамилия

Несмотря на то, что в вопросе просят ввести имя, так как это указано в загран паспорте, где отчество пишется только по-русски, в пояснении к этому вопросу чётко написано: если у вас есть отчество, вы должны его ввести вместе с именем.

При получении визы впрошлом году я не вводила отчество, потому что этот вопрос анкеты был сформулирован по-другому. В предыдущих трёх моих визах отчество указано.

In addition to the names already provided, are you now or have you ever been known by another name?

Тем, кто официально менял имя и/или фамилию, нужно указать все предыдущие имена/фамилии.

Замужние дамы, менявшие фамилию, — это, в том числе, про вас. Отвечаете «Yes» и пишите девичью фамилию.

Если фамилию меняли несколько раз, то снова отвечаете «Yes» и пишите следующую фамилию. Когда предыдущие фамилии закончились, отвечаете «нет».

Если вы никогда не меняли имени и фамилии, сразу отвечаете «No».

What is your gender, as shown in your passport or travel document?

Какой пол указан в вашем загран паспорте? Male — мужской, Female — женский.

What is your relationship status?

Семейное положение. Учтите, что civil partnership (партнёрство) — британский термин для официального однополого брака, а не «гражданский брак», как это перевели в анкете.

Если состоите в браке, что придётся доложить о своём супруге:

Address

Пишем адрес проживания, а не прописки.

Is this address also your correspondence address?

Получаете ли вы почту по этому адресу? С вами могут связаться по указанному адресу, поэтому важно указать реальный адрес, по которому вы можете получить почтовое отправление.

How long have you lived at this address?

Как долго вы проживаете по этому адресу? выбираем дни/недели/месяцы или годы и ставим число.

What is the ownership status of your home?

Кто вы по отношению к этому жилищу?

Если выбираете последний пункт, придётся дать пояснения. Например, если квартира принадлежит вашим родителям или супругу, это нужно написать:

Passport number or travel document reference number

Полный номер загран паспорта с вместе с серией.

Issuing authority

Issue date / Expiry date

Дата выдачи / окончания срока действия. Даты везде пишутся по одному и тому же принципу: день, месяц числом и год в 4 цифры.

Do you have a valid national identity card?

National identity card number

Номер российского паспорта (или свидетельства о рождении для детей младше 14 лет), вместе с серией.

Issuing authority

Место выдачи — RUS или Russia.

Issue date, Expiry date (if applicable)

Дата выдачи и окончания срока (если применимо). У российских паспортов дата окончания срока действия не указывается, так что вторую дату заполнять ненужно.

Country of nationality

Гражданство: Russian Federation

Country of birt

Страна рождения: Russian Federation или для тех, кто рождён в СССР — USSR в выпадающем меню.

Place of birth

Место рождения как указано в паспорте / свидетельстве о рождении.

Date of birth

Do you currently hold, or have you ever held, any other nationality or citizenship?

Есть ли у вас гражданство других стран? «No»

Если вдруг есть, то так выбираете «Yes» и отвечаете на дополнительные вопросы.

FAQ по переводу документов для визы в Великобританию

What is your employment status?

Занятость. Можно выбрать несколько вариантов:

Для студентов, пенсионеров и безработных вопросов по работе дальше нет.

Для самозанятых вопросов всего два:

Всем работающим придётся рассказывать о своём работодателе:

Employer’s name

Название компании, где вы работате.

Лучше всего аккуратно скопировать с бланка на английском языке, на котором вам уже сделали справку с работы. Если приходится переводить самому, то для ООО используем Ltd., для ЗАО — CJSC, для OAO — JSC. Сокращения ставятся после названия компании, ИП перед ФИО.

Рабочий адрес

Employer’s telephone number

Рабочий телефон. Здесь внезапно код страны вынесли в отдельное окно. +7 для России.

Date you started working for this employer

Дата начала работы. Месяц, год. Если не помните, то загляните в справку с места работы.

Your job title

Ваша должность. Например, Sales manager (менеджер по продажам).

How much do you earn each month — after tax?

Ваш ежемесячный доход за вычетом налога. Эту цифру вам тоже напишут в справке. Остаётся правильно выбрать валюту.

Describe your job

Опишите вашу работу. В паре предложений описываете то, что вы делает на работе. Например, я написала: «Deal with web-sites; writing goods descriptions and blogs; e-mail marketing; making photos; design web-banners and on-line ads; SMM».

Do you have another income or any savings?

Имеются ли у вас другие доходы или сбережения?

Если вы выбираете первый пункт, то появляются дополнительные вопросы про тип вашего дохода.

При выборе сбережений требуется указать их размера в фунтах. Если сбережения — ваш единственный источник денег, то будут нужны документы, подтверждающие наличие этих сбережений.

What kind of regular income do you have?

Какого типа ваши регулярные доходы?

Total amount of money that you get in a year

Общая сумма годового дохода. Берёте доход за месяц и умножаете на 12, ужасаетесь сумме.

Если ваш единственный источник денег на поездку — это сбережения, то понадобятся документы, подтверждающие их наличие

How much money are you planning to spend on your visit to the UK?

Сколько вы собираетесь потратить на поездку в Великобританию?

Сложный вопрос. Берём приблизительно стоимость авиабилетов, добавляем отель, а затем минимум 75 фунтов за каждый день пребывания. Полученную сумму округляем.

Например, едем на 5 дней (£75 * 5), перелёт, скажем, £125, отель — £250. Получаем £750.

Разумеется, ваш банковский счёт должен подтвердить, что у вас есть такая сумма.

What is the total amount of money you spend each month?

Укажите cумму своих ежемесячных расходов, включая расходы на иждивецев и выплаты по кредитам. За подсказкой можно обратиться к статистике по вашей банковской карте.

Will anyone be paying towards the cost of your visit?

Принимает ли кто-то участие в оплате вашей поездки?

Если вы всё оплачиваете самостоятельно, то ответ «No».

Если за вас полностью или частично платит кто-то другой (папа, работодатель, супруг и т.д.), отвечаете «Yes».

При положительном ответе появятся дополнительные поля:

Who is paying towards the cost of your visit?

Кто оплачивает расходы по вашей поездке?

При выборе 1-го или 3-го пункта нужно будет ввести данные лица или компании: имя/название и адрес.

Затем указать, сколько денег вам дают и почему:

How much money will they be paying towards your visit?

Сколько денег они выделят на Вашу поездку?

Сумма в рублях или фунтах.

Why are they helping to pay for your visit?

Почему они помогают оплачивать расходы по вашей поездке?

Date you plan to arrive in the UK и Date you plan to leave the UK

Планируемые даты поездки.

Можно подавать документы на визу за 3 месяца до поездки. Например, отправляя анкету 13 июля, вы можете указать начало поездки на 12 октября.

Что касается ближайших дат, то учтите, что в стандартном режиме виза делается за 15 рабочих дней, в ускоренном (за дополнительную плату) — 3 рабочих дня.

We may have to talk to you about your application.
Which language would you prefer to use?

Нам может понадобиться поговорить о вашей заявке на визу. Какой язык вы предпочитате использовать? Можно выбрать русский Russian, но говорить с вами на русском вам не обещают. На самом деле в 99% случаев это формальный вопрос. На собеседование вызывают крайне редко.

What is the main reason for your visit to the UK?

Какова основная цель вашей поездки в Великобританию?

Поскольку я пишу только про туристические визы (про другие внимательно читатайте соотвествующие документы), то предполагаю, что вы выбрали первый пункт. Обратите внимание, что имея туристическую визу, вы не сможете заключить брак на территории Великобритании. Для этой цели нужно получать «визу невесты».

Что касается обучения, то по туристической вызе вы можете обучаться до 30 дней. Т.е. для краткострочных языковых курсов ненужно оформлять студенческую визу.

После это вопрос повторяют ещё раз:

What is the main reason for your holiday visit to the UK?

Опять выбираем туризм. Если вы едете к родным или друзьям, выбирайте соответствующий пункт. И, очевидно, при этом нужно будет указать данные этих людей.

Give details of the main purpose of your visit and
anything else you plan to do on your trip.

Предоставьте детали вашего визита и что-либо другое, что вы планируете делать в поездке.

На самом деле от вас не требуют расписать ваше путешествие пошагово, как это происходит для японской визы. Можно использовать самые общие слова: Sightseeing (осмотр достопримечательностей); visiting board game conventions (посещение конвентов по настольным играм) и т.д.

Если вы планируете расширенный маршрут с передвижением по стране, то так и пишите: Visit Salisbury in order to see the Cathedral (шутка про Солсберийский собор).

Если в анкете вы написали, что собираетесь посетить Кембридж, а сами поехали в Оксфорд, никто вас наказывать не будет. Тем более, что вы пишите только про свою первую поездку по этой визе, а их может быть несколько.

Does anyone rely on you for financial support?
Include both those travelling with you and those who are not.

Нуждается ли кто-либо в вашей финансовой помощи? Включая тех, кто путешествует с вами и тех, кто остаётся дома

При положительном ответе вас попросят ввести данные этих людей независимо от того, едут они с вами в Англию или нет.

Если этот человек едет с вами, что нужно ввести:

Give details about 2 of your parents.

Введите данные о своих родителях (даже если они уже умерли): имя, фамилию, дату рождения и гражданство.

Удивительно, но при попытке указать у родителей гражданство СССР, обнаруживается, что такого нет. Так что пишите, что гражданство они не меняли.

Если у вас нет данных об одном из родителей, то заполните данные на одного, а затем нажмите на ссылку What if I do not have my parents’ details? ( Что делать, если у меня нет данных родителей?) и выберите появившуюся галочку.

Если у вас нет данных по обоим родителям, нажмите на эту ссылку сразу.

Do you have any family in the UK?

У вас есть родственники в Великобритании? Список включает:

Ряд вопросов ниже будет только в анкете для несовершеннолетних путешественников:

How many adults do you want to list on your visa?

Сколько взрослых должно быть указано в вашей визе?

В британской визе для лиц младце 18 указываются до двух взрослых, которые могут сопровождать ребёнка. Ни с кем другим ребёнка не пропустят на границе.

Which adult will travel with you?

Кто из взрослых поедет с вами?

Для выбора будут предложены родители, данные о которых внесены в анкете ранее.

Нужно будет заполнить дополнительные поля:

И либо указать, что ребёнок проживает с родителями, либо предоставить адрес.

В случае, если ребёнок едет не с родителями, выбираем пункт:

И предоставляем информацию об этом лице:

Если ребёнок едет без родителей, то необходимо разрешение на поездку с указанным взрослым.

Если выбран третий вариант, то нужно указать, кто этот сопровожадющий:

Give details — Предоставьте более подробную информацию.

Например, Trainer (тренер), Teacher (учитель), My friend’s mother (мама моего друга).

Если несовершеннолетний путешественник едет не родителями или опекуном, то при подаче документов на визу нужно предоставить согласие от родителя или опекуна на поездку в сопровождении этого лица. Этот же документ понадобится при прохождении пограничного контроля в Великобритании.

Will you be travelling to the UK as part of an organised group?

Едете ли вы в Великобританию в составе организованной группы?

Сюда относятся туристические, спортивные, рабочие или учебные группы. Если ответ положительный, нужно указать название группы.

Если вы едете семьёй или дружеской компанией, то отвечайте «No».

Will you be travelling to the UK with someone
who is not your partner, spouse, or dependant?

Едете ли вы в Великобританию с кем-то, кто не является вашим партнёром, супругом или лицом на иждивении?

Do you have an address for where you are going to stay in the UK?

Вы уже сделали необходимые приготовления, связанные с вашим проживанием в Великобритании?

Если вы отвечаете «Yes», то дальше последует вопрос

Where are you planning to stay in the UK?

Где вы планируете остановиться в Великобритании? Здесь вы или указываете название и адрес отеля, либо имя и адрес человека, у которого запланировали остановиться.

Для получения британской визы не нужна бронь отеля

Поскольку для британской визы не требуется бронировать отель, то на момент заполнения анкеты, вы можете не знать адреса, по которому будете проживать. В этом случае отвечайте «No», а на следующий вопрос дайте подробную информацию о ваших планах.

Where do you plan to stay in the UK?

Где вы планируете проживать во время поездки в Великобританию? Напишите о своих планах.

Например, I’m going to stay at a hotel in London and at the University campus in Oxford.

Have you been to the UK in the past 10 years?

Были ли вы в Великобритании за последние 10 лет?

При ответе «Yes» нужно указать количество раз.

How many times have you been to the UK in the past 10 years?

Сколько раз вы посещали Великобританию за последние 10 лет?

Select why you were in the UK:

Какова была цель вашей поездки?

Date you arrived in the UK

Дата начала поездки.

How long were you in the UK?

Продолжительность поездки в днях, неделях или месяцах.

How many times have you visited the following places in the past 10 years?
Australia, Canada, New Zealand, USA, Switzerland, European Economic Area (do not include travel to the UK)

Сколько раз за последние 10 лет вы посетили такие страны, как Австралия, Канада, Новая Зеландия, США, государства Шенгенской зоны?

Дальше нужно ввести данные по последним двум поездкам.

Which country did you visit? Do not include visits to the UK, USA, Canada, Australia, New Zealand, Switzerland or the European Economic Area.

Какие страны вы посетили кроме Великобритании, США, Канады, Новой Зеландии, государств Шенгенской зоны?

Дальше вас ждёт заполнение поездок в другие страны.

For either the UK or any other country, have you ever been:

Были ли у вас в Великобритании или любой другой стране

Надеюсь, с вами такого не случалось. Если такое было, то нужно будет указать, что случилось и в какой стране, а также дать короткое объяснение проишедшему.

Have you ever:

At any time have you ever had any of the following, in the UK or in another country?

Совершали ли вы что-либо из перечисленного, находясь на территории Великобритании или другой страны?

Дальше идёт пачка вопросов про всякие правонарушения и мерзости. Везде отвечаем «No». вы ведь законопослушный гражданин?

Многие люди недоумевают, зачем эти вопросы в анкете, ведь нормальные люди к этому непричастны, а преступник никогда не признается, что он совершил преступление. Конечно, власти Великобритании не ждут, что отъявленные негодяи расскажут про свои преступления, но если их поймают, то у властей будет письменное подтверждение вранья иммиграционной службе, а это повод взять их за попу.

Have you ever worked for any of the following types of organisation?

Работали ли вы когда-нибудь на следующий тип организаций? Вопрос включает как оплачиваемую работу, так и нет. выбирайте всё, что подходит либо отвечайте, что нет:

Я, например, работала в СМИ, поэтому мне приходится заполнять дополнительные поля.

Служившим в армии мужчинам тоже досыпят вопросов.

If you needed to add more information about your application
but were not able to, you can write it here:

Если вдруг у вас какая-то особая ситуация и вам нужно прокомментировать подаваемые документы, это как раз то место, где вы можете уточнить нюансы.

Например, если при заполнении граф про прошлые путешествия вы указали приблизительные периоды, потому что старого паспорта у вас уже нет, а точных дат вы не помните, то так и напишите.

Наконец, проверяем свои ответы, уделяя особое внимание важным данным. На этом этапе ещё можно изменить ответы.

Оплата вызового сбора

Подтверждаем анкету, выбираем продолжительность визы и оплачиваем визовый сбор.

Стандартная длительность визы полгода. Стоимость £100. Чем длиннее визу вы хотите, тем больше денег придётся выложить:

Я для себя подсчитала, что мне выгоднее получать полугодовые визы. вы решайте сами. Ходят слухи, что длинную визу получить сложнее, чем стандартную. Я не проверяла.

ВНИМАНИЕ: после того, как вы подтвердили анкету и оплатили визовый сбор внести изменения в анкету невозможно. Единственный путь — это отменять подачу, возвращать деньги и начинать всё сначала. Ищите раздел Cancel your application and get a refund.

How Many Words Do You Need to Be Fluent? [Answered]

How Many Words Does The Average Native Speaker Use?

When you set out to learn a new language, it’s common to want to know how long it will take to reach fluency. And one of the most common ways people try to gauge that is by counting the number of foreign vocabulary words they learn. So, how many words do you need to know to be fluent? The answer is quite complicated. In fact, many language learning experts often disagree.

The Problem With Counting Vocabulary Words

Despite being one of the most common ways people choose to evaluate fluency, counting words is not effective. And there are several reasons for this:

We’ve only just begun to touch on the difficulty in counting words to measure fluency. And the trouble goes deeper than just the dynamic nature of words in general. When it comes down to it, it’s even difficult just to get experts to agree on what a word is.

Defining What a Word Is

“What is a word?” is a very complex question. You might assume everyone means the same thing when they talk about a “word,” but that turns out not to be the case at all. Language experts sharply disagree with each other about the number of words people have in their vocabularies.

It doesn’t make sense. Why would people with more education have smaller vocabularies than people with less education? Where does this discrepancy come from?

The difference in the numbers comes from how experts measure data. They measure differently. And they don’t agree on the definition of “word” or the definition of “know.” So, it is not surprising that they come up with such different answers to questions about how many words people know.

How to Define What a Word Is

Some experts count every form of a word as a separate word. For example, they count each form of the verb “to see” separately. By this measurement, “to see,” “see,” “sees,” “seeing,” “saw” and “seen” would be considered six individual words. These experts apply the same logic to nouns, counting “cat” and “cats” as two separate words.

Other experts count only the root word and not its different forms. As a result, they come up with much smaller numbers. These experts count “to see,” “see,” “sees,” “seeing,” “saw,” and “seen” as only one word because they are all forms of “to see.” They also consider “cat” and “cats” as a single word because the singular and plural are forms of the same root noun.

Their thinking is that when people learn a root word, such as “to see” or “cat,” they are learning a new word for the first time. However, when the same people then learn different forms of the root word, such as “seeing” or “cats,” that should be considered an addition to their knowledge of grammar instead of an expansion of their store of new words.

How Many Words Do You Know?

After all, these experts say, this is how we learn languages. First, we learn one form of a word. Then, as we learn more about the structure of the language, we can generalize the use of the word to other situations, using its other forms.

When evaluating the number of words in people’s vocabularies, the experts who count every form of a word will come up with a much higher word count than will the experts who count only the root forms. And that’s the case even when both sets of experts are studying the same language and the same groups of people.

Which standard of measurement should you use? Neither one is right or wrong. They are both valid ways of measuring the size of people’s vocabularies. What’s important when you compare individuals or groups to each other is that you pick one method of measurement and then use it consistently in order to have meaningful results.

What Does It Mean to “Know” a Word?

Back to our original question: How Many Words Do You Need to Know to Be Fluent? We’ve defined what a word is (roughly), but we’re still not there yet. Now, we need to consider is what it means to “know” a word.

People who study languages make a distinction between what they call active vocabulary and passive vocabulary. Some think people “know” a word only if it is in their active vocabulary. However, others believe people “know” all the words in their active and passive vocabularies combined.

For both native and non-native speakers, the number of words in passive vocabularies tends to be several times larger than the number of words in active vocabularies.

People will generally absorb a new word into their passive vocabularies after they see or hear it the first few times. Then, as they encounter the word more often and as they better understand its context and different meanings, it becomes part of their active vocabularies.

One of the best ways to expand your knowledge of a language is to move words up from your passive to your active vocabulary.

Now that we have seen why language experts differ so widely when they count words in people’s vocabularies, we can return to our original question about how many words you need to know to be considered fluent. For the purpose of this discussion, we will measure vocabulary by counting only root words and not their different forms, and by counting only the words in people’s active vocabularies.

This is the approach taken by the Common European Framework of Reference for Languages (CEFR), which has become the de facto standard for grading an individual’s language proficiency. The CEFR is a current guideline used to describe achievements of learners of foreign languages across Europe and, increasingly, in other countries.

The Council of Europe created it as the main part of a project called “Language Learning for European Citizenship” between 1989 and 1996. Its main aim is to provide a method of learning, teaching and assessing which applies to all languages in Europe.

The 6 reference levels (see below) are becoming widely accepted as the de facto standard for grading an individual’s language proficiency. Using this method of measurement, we can sort people based on their language fluency into six groups or levels:

Learn the Right Words in the Right Order

A great way to accelerate your language learning is to pay attention to which words you should learn first, instead of trying to learn as many new words as fast as you can. Focus first on learning the words that will benefit you the most.

For example, in English, about 95% of everyday conversations draw from a store of only 3,000 words. Learning those 3,000 words first will be far more efficient than learning 3,000 words at random. By starting with a list of the most commonly used words, you can take a shortcut toward being able to carry on everyday conversations.

To optimize learning, someone studying English should learn to recognize the most high-volume words, such as “the,” “to be,” “and,” “have” and “you” before they tackle less common vocabulary words. Make sure you learn the basics before going on to study the names of animals and plants, current slang expressions, or other words that are not as essential to basic conversational skills.

How The Pareto Principle Helps You Reach Fluency

Vilfredo Federico Damaso Pareto was an Italian philosopher and engineer known for documenting the 80/20 rule (named after him). In short, Pareto discovered that 80% of the effects come from only 20% of the causes in many situations.

The Pareto Principle is useful in many fields because it helps people focus on the actions they can take that will have the greatest impact. For example, software developers find that fixing 20% of the bugs in a software product can eliminate 80% of the product’s defects. The trick is to concentrate on the correct 20%. In the software example, that means focusing on fixing the bugs that users report most often.

Traffic patterns also follow the Pareto Principle. In many locations, 80% of the traffic will occur during 20% of any given time period. This is useful information for city planners, who can focus their efforts to manage traffic where they will do the most good.

For language learners, this means most of your progress will come from targeted learning. While this may not break down exactly to 80 and 20%, the general rule is useful here.

Focus on High-Frequency Words in Your Target Language

That’s why many people often begin their language studies by attempting to memorize high-frequency words. Without getting into the pros and cons of this approach, adherents will often focus on the first 500–1,000 most frequently used vocabulary words in their target language.

If this is an approach you’re considering, give careful thought to where you pick up your vocabulary lists and how they were created. Going back to our exploration of “what is a word,” you may want to consider how you choose to study definitions.

You don’t need to memorize every definition of the words you are learning. That would be very time-consuming because some common words have several alternative definitions not commonly used.

For example, in English, the word “murder” normally means “to kill.” It is a word one often encounters in news reports. An alternative definition is “a flock of crows.” This second definition is not commonly known among native speakers, let alone students.

Instead, it is far more efficient to learn only a few of the most common definitions – the ones you are likely to need in ordinary conversations. Then, with experience, you will naturally learn more when you hear the words used in different contexts. In that way, through exposure to the language over time, you will assimilate the language, learning it in a natural way.

If you focus on learning words you will use the most and on learning the most useful definitions, you can learn the language far more efficiently than if you tried to learn everything at random.

How Many Words to Be Conversational?

There is no precise number that will answer the question of “how many words do you need to know to be fluent?” In part, that is because language scholars use different measurements when they count words and apply different standards to evaluate what it means to know a word.

Nevertheless, it is useful to consider how many words people know if you look at ranges, rather than at exact numbers. It then becomes possible to group people by their language proficiency according to a rough estimate of the number of words they know.

People who know 250 to 500 words are beginners. Those who know 1,000 to 3,000 words can carry on everyday conversations. Knowing 4,000 to 10,000 words makes people advanced language users while knowing more than 10,000 words puts them at the fluent or native-speaker levels.

How Many Words Do You Know?

When it comes to learning a language, all words are not equal. Learning some types of words will accelerate your progress more quickly than learning other types of words. To be most effective in learning a language, focus on the most common words in that language before starting to study more specialized sets of vocabulary. And learn the most common definitions first instead of trying to memorize every definition.

The Pareto Principle, which says 80% of effects come from 20% of causes, applies in a general way to learning a new language. That is, you will progress the fastest if you start by spending your time learning what you can use right away. If instead, you try to read a dictionary from cover to cover, learning every word and every definition in the language, much of your effort will be inefficient at best and wasted at worst.

Should You Count Words on Your Path to Fluency?

Learning the most common words and definitions puts you in a position where you can start assimilating the language in a natural way. The more you hear and read words in the language, the more you will understand new words and new meanings in context. This is similar to the way you learned your first language as a child. The more you expose yourself to your new language, the more fluent you will become.

So, how many words do you need to know to be fluent? Well, you don’t need to count the number of words you learn. You have much better things to do with your time. Instead, put your time and effort where they will do the most good. Speed up your language learning by focusing on the most commonly used words, then let your natural language-learning ability take over.

This combination of targeted studying and assimilating language by experience is the most powerful and efficient way to master a new language.
