Discount Calculator

Stacked discounts apply sequentially, not additively. A 20% discount followed by 10% off does not equal 30%. The second discount applies to the already-reduced price. For example, $100 with 20% then 10% off becomes $72, not $70.

Switch to the Find Original mode, enter the sale price and the discount percentage. The calculator divides the sale price by (1 minus the discount rate). For example, $75 after a 25% discount means the original price was $100.

Switch to the Find Discount % mode and enter both the original and sale prices. The calculator computes (original minus sale) divided by original, times 100. This tells you the exact percentage discount applied.

The effective discount shows the total percentage off the original price after all stacked discounts are applied. It is always less than the sum of individual discounts because each successive discount applies to a smaller amount.
