About the Sales Tax Calculator
Sales tax is a percentage-based tax added to the price of goods and services at the point of sale. The rate varies by state, county and city.
Formula: Sales Tax = Price × (Tax Rate ÷ 100) · Total = Price + Sales Tax
Use this calculator to quickly find how much tax will be added to a purchase, or to back into the pre-tax price when you only know the total.
