Sales Tax Calculator

Enter the item price and your local tax rate percentage. The calculator instantly shows the tax amount and the total price including tax. For example, a $100 item with 8.5% tax results in $8.50 tax and $108.50 total.

Reverse calculation lets you find the pre-tax price when you know the total amount paid. This is useful when a receipt shows only the final total and tax rate, and you need to determine the original price before tax was applied.

Sales tax rates vary by state, county, and city. Check your local government website or a recent receipt for your exact combined rate. Common US state rates range from 0% to over 10% when local taxes are included.

This calculator uses a single combined tax rate. If your area has separate state, county, and city taxes, add them together and enter the total rate. For example, 6% state plus 2% local equals 8% combined rate.
