US Sales Tax Calculator
Calculate US sales tax on a purchase using your state's rate.
Combined rate is a population-weighted state average — actual local sales tax varies by city/county.
About the US Sales Tax Calculator
The US Sales Tax Calculator gives you an instant answer from just a few inputs — state, purchase amount. It runs entirely in your browser, so the numbers you enter stay private and never touch a server, and the result recalculates the moment you change a value. It's free to use with no sign-up, no limits, and nothing to install.
Worth Knowing
US sales tax is layered and local — there's no national rate, and the total you pay combines state, county, and city rates, which is why the same item costs different amounts across town lines. Five states (including Oregon and Delaware) charge no state sales tax at all. This tool uses a state-level rate, so actual checkout totals in areas with local add-ons may run higher; groceries and medicine are often exempt or taxed at reduced rates.
