Sales Tax Calculator
Calculate sales tax and total purchase price using any state or local tax rate.
Use your local sales-tax rate to estimate the tax and final purchase total. Because rates can vary by state, county, city, and product type, this tool lets you enter the exact rate yourself.
Why you enter the rate
There is no single U.S. sales-tax percentage. State and local rules can differ, and some purchases may be exempt or taxed differently. Enter the rate shown by your retailer, receipt, or local tax authority.
Sales-tax formula
Tax equals the pre-tax price multiplied by the tax rate divided by 100. The total equals pre-tax price plus tax.
Reverse calculations
If you only know the final price and want to estimate the pre-tax price, divide the final price by 1 plus the rate as a decimal.
Frequently asked questions
Does this know my city tax rate?No. The tool intentionally asks you to enter the rate so it does not rely on outdated location data.
Can I use a combined state and local rate?Yes. Enter the combined rate that applies to your purchase.
