Double Discount Calculator
Apply two stacked discounts and see the true price.
Why stacked discounts fool you
Retailers love stacked discounts because they sound bigger than they are. Two 20%-off deals feel like 40% off, but the second discount applies to the already-lowered price, so the real saving is less.
A 100 item with 20% off then another 10% off ends at 72 — a 28% total discount, not 30%. This tool shows the true final price and combined percentage.
