Frequently asked questions

Complete guide to Sales Tax Calculator

How is sales tax calculated?

Sales tax is a percentage of the pre-tax price. Tax amount = price × (rate ÷ 100). Total you pay = price + tax amount. Rates vary by state, county, and city in the USA and by country. This calculator gives exact tax and total for any price and rate.

Sales tax by state (USA)

State sales tax rates range from 0% (e.g. Oregon, Montana) to over 7%. Many states add local taxes, so combined rates can be 8–10% or higher. Always use the rate that applies to your location and the type of item (some items are exempt).
