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.
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.
