Sales Tax Calculator
Calculate sales tax fast with our free sales tax calculator. Enter the price and tax rate to see the tax amount and the total price you will actually pay.
About this tool
The price on the tag is rarely the price at the register. Our free sales tax calculator tells you exactly how much tax gets added and what you will actually pay, in one click.
Enter the pre-tax price and your local tax rate. The tool instantly shows the tax amount and the final total - no mental math at the checkout line.
How to use
Type the item's price before tax, then enter the sales tax rate as a percentage. In the US, combined state and local rates typically range from 0 to about 10 percent - check a receipt from a local store if you are unsure.
Press Calculate Tax to see the tax amount and the total price. Handy for budgeting big purchases like electronics or furniture.
The math behind it
The math is simple: Tax = Price x Rate / 100, and Total = Price + Tax. A $100 item at 8 percent tax adds $8, for a total of $108.
Some places layer multiple taxes (state plus county plus city). If yours does, just add the rates together first and enter the combined percentage - the result is the same.
