🧾 Sales Tax & VAT Calculator

Add tax to a net price or work backwards to remove VAT from a gross total.

About this tool

Two calculations in one. Add tax takes a net (pre-tax) amount and adds the tax to show the gross price a customer pays. Remove tax (reverse VAT) takes a gross amount that already includes tax and works out the original net price and the tax portion. Pick a country preset or type any rate.

All maths runs in your browser. Results are estimates — always confirm the exact rate and rounding rules that apply to your transaction.
