Calculate sales tax on purchases. Add tax to a before-tax price, or back out the pre-tax price from a total.
Quickly calculate sales tax on any purchase, or work backward to find the pre-tax price, with our free sales tax calculator.
Tax Amount = Price × Tax Rate. Total Price = Price + Tax Amount. To reverse-calculate: Pre-Tax Price = Total Price ÷ (1 + Tax Rate).
Sales tax is typically set at state, county, and sometimes city levels, so combined rates differ significantly by location.
Check your local government's revenue or taxation department website for current combined sales tax rates.
