Sales Tax Calculator

Calculates the tax on a purchase and the final amount payable. In the United States, sales tax is added at the register rather than shown on the shelf price, so the total is often a surprise until you work it out.

What the Sales Tax Calculator does

Rates vary enormously because state, county and city taxes stack. The combined rate in one town can differ from the next by several percentage points, so check the rate for the exact location rather than assuming a state figure.

  1. 1Enter the pre-tax amount.
  2. 2Enter the combined sales tax rate for the location.
  3. 3The tax is calculated as amount × rate ÷ 100.
  4. 4It is added to the original to give the total.
  5. 5Both the tax and the total are shown.
