About the Discount Calculator

Know what you'll really pay before checkout. Enter the original price and the discount to see the final price and how much you save. Shopping with an extra coupon? Add a second discount: stacked discounts multiply rather than add, and the calculator shows the true combined percentage.

How to use it

  1. Enter the original price and discount percentage.
  2. Optionally add a second discount and sales tax.
  3. Read the final price, savings and effective discount.

Good to know

  • Stores sometimes apply coupons before or after other discounts; the order doesn't change the result for percentage discounts.

Frequently asked questions

Is 20% + 20% off the same as 40% off?

No, it's 36% off: the second 20% applies to the already-reduced price.

How do I calculate a discount by hand?

Multiply the price by (1 − discount/100). $80 at 25% off is $80 × 0.75 = $60.
