Add or strip sales tax from any price, forwards or backwards.
Sales tax is calculated as the price multiplied by the tax rate. The final total is the original price plus that tax amount.
Tax amount
Tax = Price × Rate
Total price
Total = Price + Tax = Price × (1 + Rate)
Estimates only. Confirm the exact applicable tax rate for your location.
Combine your state, county, and city rates. Many U.S. localities publish a single combined rate you can enter directly.
To find the pre-tax price from a total, divide the total by (1 + rate). For example, a $108.25 total at 8.25% is $108.25 / 1.0825 = $100.
