How to use the discount calculator

  1. Enter the original price and the discount percentage.
  2. Add a second discount for “extra 10% off sale prices” deals, and the quantity.
  3. Use the reverse calculator to see the real discount between an old and a new price.

Stacked discounts are not added together: 25% off and then an extra 10% off is 32.5% in total, not 35%. This calculator shows the real figure so you can compare Black Friday, January sales and coupon deals honestly.
