Free VAT, GST and Sales Tax Calculator — Add or Remove Tax
VAT (value-added tax), GST (goods and services tax) and sales tax are percentages added to the price of goods and services. To quote a customer you often need to add the tax to a net price; to keep your books you often need to strip the tax out of a gross (tax-inclusive) price. This calculator does both in one step.
Enter an amount and a tax rate, choose whether to add tax or remove it, and see the net amount, the tax amount and the gross total. Quick presets cover common rates such as 20% (UK), 19% (Germany), 5% GST (India lowest slab), 10% (Australia), 5% (Canada GST) and 7% (US average sales tax), and you can type any custom rate.
