Stacked Discount Calculator

Free stacked discount calculator: apply two percentage discounts in sequence and see the final price and effective discount.

How the stacked discount calculator works

Enter the original price and two discount percentages to see the final price and the combined discount.

Final price = price × (1 − d1) × (1 − d2). Effective discount = 1 − final ÷ price.

Example: 100 with 20% then 10% off is 72, a combined discount of 28%, not 30%.

The second discount applies to the already reduced price, so the combined discount is smaller than the sum of the two.
