Free VAT Calculator – Add or Remove VAT
VAT calculations often require moving between net price, tax amount and gross price. Choose whether the entered amount excludes or includes VAT, set the rate, and the calculator returns all three values immediately in your browser.

How to read the result
When adding VAT, the entered amount is treated as net. When removing VAT, the entered amount is treated as gross and the net value is calculated by dividing by `1 + rate/100`, not by simply subtracting the percentage.
Limitations
The default rate is 20% for convenience, but VAT rules and applicable rates depend on country, product, transaction and tax status. This calculator performs arithmetic only and is not tax advice.
