Enter a price to see the sales tax and the total.

Formula
total = price × (1 + tax rate ÷ 100)
With your numbers
—

The tax is rounded to the nearest cent. Stores and states differ on whether they round each item or the whole purchase, so a receipt can be off by a cent or two.

An estimate, not tax advice

The state rate comes from the state’s own tax agency, but what you pay depends on the exact address, on what you buy (many states tax food, clothing, or medicine differently or not at all), and on any special districts. Check the final amount on your receipt or with your state’s tax agency. This tool is not financial or tax advice.

Taking sales tax out of a total in Washington

If a $500 total already includes the 6.5% state rate, the price before tax is $469.48 and the tax is $30.52. With an example 2% local rate on top (8.5% combined), the same $500 holds a price of $460.83 and $39.17 of tax. The reverse calculation divides by 1 plus the rate; it does not subtract the percentage.

Finding your local rate

Use the state’s own rate tool to find the local rate for an address, then type it into the calculator. Food, clothing, medicine, and services can be taxed differently from other goods, so check the tax agency before relying on the result for a large purchase. Open the sales tax calculator for any other state.
