VAT Calculator
Add VAT to a net price or remove it from a VAT-inclusive (gross) price at any rate. The result shows the net amount, the VAT and the gross amount — the three figures an invoice needs. It works the same way for GST.

Common VAT and GST rates
Standard rates: United Kingdom 20%, Germany 19%, France 20%, Italy 22%, Spain 21%, Netherlands 21%, Ireland 23%. EU countries must set a standard rate of at least 15%; Hungary’s 27% is the highest.
Most countries also have reduced rates for things like food, books or energy — 5% and 0% in the UK, 7% in Germany. GST works the same way: 10% in Australia, 15% in New Zealand and 5% federally in Canada.
Rates change, and the right rate depends on what is being sold. Confirm with your tax authority before invoicing; this calculator is not tax advice.
The VAT fraction
VAT is charged on the net price, so it is a smaller share of the gross price than the headline rate. At 20%, the VAT inside a gross price is 20 ÷ 120 = one sixth of it, not one fifth. A £120 price contains £20 of VAT, not £24.
For any rate, VAT = gross × rate ÷ (100 + rate).
Questions people ask
How do I add 20% VAT?
Multiply the net price by 1.2. £100 net becomes £120 gross, of which £20 is VAT.
How do I remove 20% VAT from a price?
Divide by 1.2. A £99 gross price is £82.50 net plus £16.50 VAT. Taking 20% off £99 would give £79.20, which is wrong.
What is the difference between VAT and sales tax?
Sales tax is charged once, at the final sale to the consumer, and is usually added at the till. VAT is charged at every stage of the supply chain, with businesses reclaiming the VAT they paid, and consumer prices are normally shown with VAT already included.
