Discount Calculator

Calculate sale prices, savings and percent off

About the Discount Calculator

The Discount Calculator works out sale prices and savings three ways: apply a percentage off to get the final price, work backward from an original and sale price to find the percent off, or calculate a final price that includes both a discount and tax.

How to Calculate a Discount

  1. Choose the mode that matches what you know — % Off, Price comparison, or Final + Tax.
  2. Enter the relevant prices, percentage or tax rate.
  3. Click Calculate to see the result.
