How do I add VAT to a price?

Multiply the net price by the VAT rate to get the VAT amount, then add it to the net price. For example, at 20% VAT a net price of 100 becomes 100 × 0.20 = 20 VAT, giving a gross price of 120. Use Add VAT mode and the calculator does this for you.

How do I remove VAT from a gross price?

Divide the gross price by 1 plus the VAT rate. At 20% VAT, a gross price of 120 ÷ 1.20 = 100 net, so the VAT included was 20. Use Remove VAT (reverse) mode to back the VAT out of a total.

Is VAT the same as US sales tax?

They are similar consumption taxes but work differently. VAT is charged at each stage of the supply chain and is common in the UK and EU, while US sales tax is charged once at the final sale. This tool works for any percentage rate, so it handles both.

What is VAT?

VAT (Value Added Tax) is a consumption tax added to the price of most goods and services. It's charged as a percentage of the price and collected by the seller, then passed on to the tax authority. The UK and EU use VAT widely; similar taxes elsewhere include GST.

Three figures matter on any VAT calculation: the net price (before VAT), the VAT amount itself, and the gross price (net plus VAT). This calculator works in both directions — add VAT to a net figure, or remove it from a gross figure — at whatever rate applies to you. When you're ready to bill, drop the figures into a VAT invoice.

The maths

How VAT is calculated

Adding VAT

Start from the net price, multiply by the rate to get the VAT, then add it back:

VAT = Net × rate
Gross = Net + VAT

Removing VAT (reverse)

Start from the gross price and divide it out to find the net, then the difference is the VAT:

Net = Gross ÷ (1 + rate)
VAT = Gross − Net

Worked example at 20%

A net price of £100 gains £20 of VAT for a £120 gross. In reverse, £120 gross ÷ 1.20 = £100 net, with £20 of VAT included.

FAQ

VAT calculator questions

Multiply the net price by the VAT rate to get the VAT amount, then add it to the net price. At 20%, a net price of £100 becomes £100 × 0.20 = £20 VAT, for a £120 gross. Use Add VAT mode and the calculator does it for you.

Divide the gross price by 1 plus the VAT rate. At 20%, £120 ÷ 1.20 = £100 net, so the VAT included was £20. Use Remove VAT (reverse) mode to back the tax out of a total.

Net is the price before VAT, gross is the price after VAT is added, and the VAT amount is the difference between them — so Gross = Net + VAT.

They're similar consumption taxes but work differently. VAT is charged at each stage of the supply chain (common in the UK and EU), while US sales tax is charged once at the final sale. This tool works for any percentage rate, so it handles both.
