Sales Tax Calculator
Add sales tax to any price. Free, instant and no sign-up.
How this sales tax calculator works
Enter the pre-tax price and your local sales tax rate. The calculator shows the tax amount and the final price you will pay at the register. Sales tax in the United States is set by states and often by counties and cities too, so the combined rate differs from place to place.
The formula
Sales tax = price × rate ÷ 100. Total = price + sales tax.
Example
A $250 purchase with 8.25% sales tax has $20.63 of tax, for a total of $270.63.
Tips
Look up the combined state and local rate for your ZIP code for an accurate result. Some states have no statewide sales tax, and many exempt groceries or clothing, so the rate that applies can depend on what you buy.
