Sales Tax Calculator
Work out the sales tax on any purchase. Enter the price and choose your state, and the calculator applies the 2026 average combined rate — the state sales tax plus the average local rate — to show the tax and your total at checkout.
Sales tax in the U.S. is set at the state and local level, so the total rate varies widely: five states charge none at all, while combined rates top 10% in others. This tool uses each state’s average, with a per-state page for all 50 states and D.C.
Uses each state’s 2026 average combined rate (state plus the population-weighted average local rate). Your city or county rate may differ — check your local rate for an exact figure.

Estimate only. Rates are 2026 averages from the Tax Foundation (state rate plus the population-weighted average local rate) and can differ from your exact city/county rate. Some items — groceries, prescriptions, clothing — are taxed at reduced rates or exempt in many states, which this calculator does not model.

Calculation Formulas
The combined rate is the state sales tax plus the average local (city/county) rate for that state. Multiply the pre-tax price by it to get the tax; add it back for the total.
Example:
A $100 purchase in a state with an 8.5% combined rate is $8.50 in sales tax, for a $108.50 total.
Local sales taxes are averaged across a state and weighted by population, so this is the typical total rate a shopper pays — your exact city or county rate may be a little higher or lower.

Standards & Sources
Last verified: August 2026
- Tax Foundation sales tax data
Rates come from the Tax Foundation’s “State and Local Sales Tax Rates, Midyear 2026” — statutory state rates plus population-weighted average local rates as of July 1, 2026.
- State averages, not exact local rates
Local sales tax is set by thousands of cities, counties, and special districts. This calculator uses each state’s population-weighted average, so a specific location can differ from the figure shown.
- Exemptions not modeled
Many states tax groceries, prescription drugs, or clothing at reduced rates or exempt them entirely. This calculator applies the general rate and does not account for product-specific exemptions.

Frequently Asked Questions
How do I calculate sales tax?
Multiply the pre-tax price by the sales tax rate (as a decimal), then add it to the price. For example, $100 at an 8.5% combined rate is $100 × 0.085 = $8.50 in tax, for a $108.50 total.
What is the combined sales tax rate?
It’s the state sales tax rate plus the local (city, county, and district) rate. Because local rates vary within a state, this calculator uses each state’s population-weighted average local rate to estimate the typical total you’d pay.
Which states have no sales tax?
Five states have no statewide sales tax: Delaware, Montana, New Hampshire, and Oregon charge none at all, while Alaska has no state rate but allows local sales taxes. Everywhere else, a state rate (and often a local rate) applies.
Why might the calculator’s rate differ from what I paid?
This tool uses your state’s average combined rate, but the actual rate depends on the exact city, county, and special districts where the sale happens. Some goods — groceries, prescriptions, clothing — are also taxed at reduced rates or exempt in many states.
