Discount Calculator

Free discount calculator. Find the sale price and how much you save from a percentage off.

See the final price after a percentage discount and exactly how much money you save.

How the Discount Calculator works

Sale price = original × (1 − discount % ÷ 100); savings = original − sale price.

Example calculation

A $120 item at 25% off costs $90, saving you $30.

Tips for using the Discount Calculator

  • Stacked discounts apply sequentially, not added together.
  • Discounts are applied before sales tax.
  • Compare unit prices, not just headline percentages.
