VAT calculator.

Enter an amount, pick a rate: net, VAT and gross appear instantly.

The formulas

VAT = net × rate. Gross = net × (1 + rate). Net = gross ÷ (1 + rate). Example at 20%: £1,000 net → £200 VAT → £1,200 gross.

Rates are indicative standard rates as of November 2026; reduced rates exist in most countries. In the US there is no VAT; sales tax depends on the state.
