Tax Calculator

Calculate tax amount on any price — add tax or extract from tax-inclusive totals.

Tax Calculator computes tax amounts in two modes: adding a percentage tax rate to a pre-tax amount to find the total, or extracting the tax from a tax-inclusive price to find the pre-tax base. Common tax rates (5%, 7%, 8.5%, 10%, 13%, 15%, 20%) are available as quick-pick buttons, or you can enter any custom rate. Shoppers use it to estimate the final price on a purchase before checkout. Business owners use it to figure out how much of an invoice amount to remit as tax. Accountants use it to quickly sanity-check tax calculations. International travelers use it to understand VAT and GST amounts in different countries. The two modes cover the vast majority of everyday tax calculation scenarios.
