🧾 VAT Calculator — Add or Remove VAT & Sales Tax
Instantly calculate VAT or sales tax in both directions: enter an amount and a tax rate to see the net, tax, and gross figures — or work backwards from a tax-inclusive price to find the pre-tax amount. Completely free, runs 100% in your browser, and nothing is ever uploaded to a server.
Private by design. This tool runs entirely in your browser — nothing you enter is uploaded or stored, and it works offline.
About
This VAT calculator supports two modes. In Add VAT mode, you enter a net (pre-tax) amount and a tax rate; the tool multiplies the net by the rate to give you the tax amount, then adds both together for the gross (tax-inclusive) total. In Remove VAT mode, you enter a gross (tax-inclusive) amount and a tax rate; the tool divides by (1 + rate) to recover the net, then subtracts to find the tax portion. Common rates for major countries are listed as quick-select buttons (e.g., 20% UK, 19% Germany, 10% Japan), but you can type any custom rate. Because all calculations run client-side in your browser, no financial figures are ever sent to a server or stored anywhere outside your device.
