When two discounts apply one after another, the second discount is calculated on the already-reduced price, not the original price. The formula is: Final Price = Original Price × (1 − Discount1 ÷ 100) × (1 − Discount2 ÷ 100).
For example, a 1000 item with 20% off first drops to 800, then a further 10% off that 800 (not the original 1000) removes another 80, giving a final price of 720. The effective total discount is 28%, not 30%, since the second discount applies to a smaller base amount, this is a common mistake when combining coupon codes or sale discounts.
Adding the two discount percentages together (assuming 20% + 10% = 30% off), as the worked example shows, stacked discounts multiply, not add, and the true effective discount is smaller.
Applying both discounts to the original price separately instead of applying the second discount to the already-discounted price.
Forgetting that a coupon code and a storewide sale often stack this way too, not as a simple sum, worth checking the actual final price before assuming the advertised combined percentage.
No. Stacked discounts apply one after the other to the already-reduced price, so 20% then 10% works out to an effective discount of 28%, not 30%, since the second discount applies to a smaller amount.
No, applying discount A then discount B gives the same final price as applying B then A, multiplication is commutative either way.
