About Sales tax calculator

Adds sales tax to a price, or removes it to find the price before tax. To go backwards, divide the total by 1 plus the rate rather than subtracting the rate, which is a common mistake. A 107 total at 7 percent tax means a 100 pre-tax price.

How to use Sales tax calculator

  1. Enter the price and the tax rate.
  2. Choose whether to add tax or remove it.
  3. Read the tax amount and the total or pre-tax price.

Frequently asked questions

How do I find the price before tax?

Divide the total by 1 plus the tax rate as a decimal. A total of 110 with 10 percent tax gives 100 before tax.

Why can't I just subtract the tax percent from a tax-inclusive price?

Tax was added on top of the base, so divide by 1 plus the rate. For 120 with 20% tax, the base is 120 divided by 1.2, which is 100.
