Introduction

This free VAT calculator lets you add or remove VAT from any amount in seconds. VAT stands for Value Added Tax. It is a tax added to the price of goods and services in many countries, including the UK and most of Europe. Our tool supports the standard UK VAT rate of 20%, the reduced rate of 5%, and the zero rate of 0%. You can also pick from common global rates or type in your own custom rate.

To use the calculator, choose whether you want to add VAT to a net price or remove VAT from a gross price. Then enter your amount, select your VAT rate, and see your results right away. The calculator shows you the net amount, the VAT amount, and the gross total. It also gives you a clear step-by-step breakdown of the math and a chart that shows how much of the total price is tax.

Whether you run a small business, work in accounting, or just need to check a receipt, this VAT calculator makes the job quick and simple. Select from seven currencies, copy results to your clipboard with one click, and use the number pad or your keyboard to enter values fast.

How to Use Our VAT Calculator

Enter your amount, pick a VAT rate, and choose whether to add or remove VAT. The calculator will show you the net price, VAT amount, and gross total right away.

Choose your calculation mode. Click "Add VAT" if you have a price without tax and want to find the total. Click "Remove VAT" if you have a price that already includes tax and want to find the original amount.

Select your currency. Use the dropdown menu to pick your currency. You can choose from British Pound, US Dollar, Euro, and other major currencies. If you need to convert between currencies, try our currency calculator.

Enter your amount. Type your number using the on-screen keypad or your keyboard. The display will update as you type. Press "C" to clear the entry or "⌫" to delete the last digit.

Set your VAT rate. Pick a common rate from the preset buttons, drag the slider, or type an exact percentage in the rate box. The UK standard rate of 20% is selected by default.

View your results. Click "Calculate" or watch the results update live as you type. You will see the net amount, VAT amount, and gross total. Use the copy buttons to copy any result to your clipboard. A step-by-step breakdown and pie chart are shown below the results.

What Is VAT?

VAT stands for Value Added Tax. It is a tax added to the price of most goods and services when you buy them. The business collects this tax from you and then pays it to the government. VAT is used in over 160 countries around the world, including the United Kingdom, all European Union member states, Australia, Canada, and Japan. In countries like Australia and Canada, a similar consumption tax is known as the Goods and Services Tax — you can calculate it with our GST calculator. In the United States, a comparable levy at the point of sale is handled through our sales tax calculator.

How Does VAT Work?

When a product costs £100 and the VAT rate is 20%, the shop adds £20 in tax. You pay £120 in total. The £100 is called the net price (the price before tax). The £20 is the VAT amount. The £120 is called the gross price (the price after tax). If you frequently need to convert between net and gross figures, our net to gross calculator is another handy tool. Every time a product moves from one business to another, VAT is charged at each step. But businesses can claim back the VAT they paid, so the final customer is the one who truly pays it.

UK VAT Rates

In the United Kingdom, there are three main VAT rates:

  • Standard rate — 20%: This applies to most goods and services.
  • Reduced rate — 5%: This applies to some items like home energy, child car seats, and certain health products.
  • Zero rate — 0%: This applies to essentials like most food, children's clothing, and books. The tax is technically charged, but at 0%.

Adding vs. Removing VAT

There are two common calculations people need to do. Adding VAT means you start with the net price and want to find the total price including tax. You multiply the net price by the VAT rate and add it on. Removing VAT means you start with the gross price and want to find out how much of it is tax. You divide the gross price by 1 plus the rate to get the net amount. This reverse calculation works the same way as a reverse tax calculator.

Who Needs to Calculate VAT?

Small business owners, freelancers, and accountants calculate VAT every day. If your business earns more than the VAT threshold, you must register for VAT and charge it on your sales. You also need to file VAT returns with HMRC. Freelancers and sole traders should also consider their broader tax obligations using a self-employment tax calculator, and business owners may find a corporation tax calculator useful at year-end. To understand your overall take-home earnings after VAT, income tax, and National Insurance, check out our take-home pay calculator. Shoppers may want to calculate VAT to understand how much tax they are paying on a purchase or to compare prices across countries with different tax rates. For a broader look at how different taxes affect your finances, our tax calculator can help.

Frequently asked questions

How do I add VAT to a price?

Click the Add VAT button at the top of the calculator. Type in your net price (the price before tax). Pick your VAT rate. The calculator will multiply your price by the rate and add the tax on top. For example, £100 at 20% VAT gives you £120 gross.

How do I remove VAT from a price?

Click the Remove VAT button. Enter the gross price (the price that already includes tax). The calculator divides by 1 plus the rate to find the net amount. For example, £120 at 20% VAT gives you £100 net and £20 VAT.

What VAT rate should I use?

In the UK, most goods and services use the standard rate of 20%. Some items like home energy use the reduced rate of 5%. Essentials like most food and children's clothes use the zero rate of 0%. If you are in another country, check your local tax authority for the correct rate.

Can I use a custom VAT rate?

Yes. You can type any rate from 0% to 27% in the Exact % box on the right side. You can also drag the slider to set a rate in steps of 0.5%. This is useful if your country uses a rate not shown in the preset buttons.

What currencies does the calculator support?

The calculator supports seven currencies: British Pound (GBP), US Dollar (USD), Euro (EUR), Australian Dollar (AUD), Canadian Dollar (CAD), Swiss Franc (CHF), and Japanese Yen (JPY). Use the dropdown menu to switch between them.

How do I copy a result?

Click the small copy icon next to any result (Net, VAT, or Gross). The number will be copied to your clipboard. The icon will change to a checkmark to confirm it worked.

Can I use my keyboard instead of the on-screen keypad?

Yes. You can type numbers, use the decimal point, press Backspace to delete, or press Escape to clear the entry. The on-screen keys will flash as you type.

What is the formula to add VAT?

The formula is: Gross = Net × (1 + VAT rate ÷ 100). For example, at 20% VAT: Gross = £100 × 1.20 = £120. The VAT amount alone is Net × (VAT rate ÷ 100), which is £100 × 0.20 = £20.

What is the formula to remove VAT?

The formula is: Net = Gross ÷ (1 + VAT rate ÷ 100). For example, at 20% VAT: Net = £120 ÷ 1.20 = £100. The VAT amount is Gross minus Net, which is £120 − £100 = £20.

What do net, gross, and VAT mean?

Net is the price before tax. VAT is the tax amount added to the price. Gross is the total price after tax has been added. Gross always equals Net plus VAT.

Does the calculator round the results?

Yes. All results are rounded to two decimal places, which matches how money works in most currencies. This means your answers are shown in pounds and pence, dollars and cents, and so on.

What does the pie chart show?

The pie chart shows how the gross price breaks down into two parts: the net amount and the VAT amount. It helps you see at a glance how much of the total price is tax.

What does the step-by-step section show?

It shows the full math behind your result, broken into clear steps. You can see the values used, the formula applied, and how the final answer was reached. This is helpful for learning, checking homework, or verifying a tax calculation.

Is this calculator free to use?

Yes. The VAT calculator is completely free. There are no sign-ups, no limits, and no hidden costs. You can use it as many times as you need.

Can I use this calculator on my phone?

Yes. The calculator is fully responsive and works on phones, tablets, and desktops. The on-screen keypad makes it easy to enter numbers on a touchscreen.

What happens when I click the Reset button?

The Reset button sets everything back to the default: currency to GBP, mode to Add VAT, amount to 1,000.00, and rate to 20%. It gives you a clean start.

What does the New Calculation button do?

The New Calculation button clears the amount back to 1,000.00 but keeps your current currency, mode, and VAT rate. Use it when you want to calculate a new amount with the same settings.

Why does the live preview update as I type?

The live preview gives you a quick estimate before you finish typing. It shows the approximate gross (when adding VAT) or net (when removing VAT) so you can check your entry is correct as you go.

Can I calculate VAT for countries outside the UK?

Yes. The calculator includes common global VAT rates like 7%, 10%, 19%, 21%, 23%, 25%, and 27%. You can also type any custom rate. Just pick the matching currency and rate for your country.

Is VAT the same as sales tax?

They are similar but not the same. VAT is charged at every stage of production and supply, and businesses can reclaim the VAT they pay on their costs. Sales tax is charged only once at the final point of sale to the customer. VAT is common in the UK and Europe, while sales tax is used in the United States.
