USA Sales Tax Calculator

Calculate sales tax and total price using approximate combined state and local sales tax rates.

These are approximate average combined state + local rates and a general estimate only — actual sales tax depends on your specific city/county and the type of item purchased (some categories are exempt or taxed differently). Verify with your state's department of revenue.

Sales tax in the US is set at the state level, and many states also allow local (county/city) sales taxes on top, so the effective rate varies even within a state. This calculator uses approximate average combined (state + local) rates for a selection of states — for an exact rate, check your specific city/county.

Example

  • With the default values shown above, this calculator returns: Sales Tax ≈ $8.82; Total Amount ≈ $108.82.
