VAT & Sales Tax Calculator

Add or remove VAT, GST or sales tax at any rate, with the net and tax split out.

To calculate VAT, enter the amount and the tax rate, then say whether the figure already includes tax. Adding tax multiplies by 1 plus the rate; removing it divides by the same figure — subtracting the percentage instead is the most common mistake.

Frequently asked questions

How do I remove VAT from a gross price?

Divide by 1 plus the rate, not subtract the rate. At 20%, a £120 gross price is £100 net — subtracting 20% would give £96, which is the most common arithmetic error in invoicing.
