This page opens the VAT calculator with United Kingdom chosen as the country. The rate box shows 20%, and the quick picks are 20% and 5%. The net price, the VAT and the gross price update as you type.
To take VAT out of a price that already includes 20%, divide by 1.2. The VAT is one sixth of that total, so £120 contains £20 of VAT on a £100 net price. Rates can change, so confirm the current rate with the tax authority before you use a figure on an invoice.
How to add or remove VAT
- Type the amount, then choose your country for its rate, or type the rate or tap a quick pick.
- Choose Add tax for a net price, or Remove tax for a gross price.
- Read the net, tax and gross figures. The main answer is highlighted.
Questions
How do I find the VAT inside a price that includes it?
At 20%, divide the total by 6: £60 contains £10 of VAT. At the 5% rate the VAT is one twenty-first of the total, so £21 contains £1.
Can I use a rate other than 20% or 5%?
Yes. Type any rate from 0 to 100 in the rate box. The two quick picks are only shortcuts, and the country stays selected.
What is the difference between net and gross?
Net is the price before tax. Gross is the price with the tax added on. Gross is always net plus the tax amount.
How do I add VAT to a price?
Multiply the net price by the rate written as a decimal, then add the result. At 20%, 100 × 1.2 = 120, so the tax is 20 and the gross price is 120.
How do I take VAT out of a price?
Divide the gross price by 1 plus the rate written as a decimal. Removing 20% from 120 gives 120 ÷ 1.2 = 100 net, and the tax is the difference, 20.
Is GST or sales tax worked out the same way?
The arithmetic is the same for any percentage tax added on top of a price. Which tax applies, which rate is right and how it is shown on an invoice depend on where you are, so check the official rules for your case.
