Sales Tax Calculator
Enter a pre-tax price and sales tax rate to see the tax amount and total price. This is the forward calculation — for the reverse, see our reverse sales tax calculator.
Sales Tax Formula
Tax Amount = Pre-Tax Price × (Tax Rate ÷ 100)
Total Price = Pre-Tax Price + Tax AmountNeed the Reverse?
If you already know the total and need to find the pre-tax price, use our reverse sales tax calculator. It works backwards from the total to give you the original price.
Finding Your Tax Rate
Use the combined rate for your city — not just the state rate. See our state-by-state tax rate pages for pre-loaded rates, or check your state's department of revenue for the exact current rate.
