About the Discount Calculator

Enter the original price and the discount to see the price you actually pay and the amount you save. A reverse mode works backwards from the sale price to tell you what percentage off you were really given, which is useful when a sign only shows the new price.

Stacked discounts are handled properly, and they are the reason this calculator is worth using. An extra 20 percent off an item already reduced by 30 percent is not 50 percent off. The second discount applies to the already-reduced price, so you pay 56 percent of the original and the true saving is 44 percent. The calculator shows each stage so you can see where the missing six percent went.

Key features of the Discount Calculator

Stacked discounts done correctly

An extra 20 percent off an item already reduced by 30 percent is not 50 percent off — you pay 56 percent of the original, and the true saving is 44 percent.

Each stage shown

The intermediate price after every discount is printed, so you can see where the missing percentage went.

Reverse mode

Work back from a sale price to find what percentage off you were really given, which is useful when a sign only shows the new price.

Saving in cash as well as percent

Both figures are reported, because one of them is what you actually feel.

Instant recalculation

Adjust the discount and every figure updates as you type.

Frequently asked questions

Multiply the price by the discount percentage divided by 100 to get the saving, then subtract it. A 25 percent discount on 80 is a saving of 20, so you pay 60.
