Each discount applies to the price left after the previous one. For example, 20% then 10% off gives 28% off in total, not 30%.
How to use
- Choose the figure to find. Select Sale price, Discount %, Original price or Stacked discounts.
- Enter the known amounts. For example, an €80 original price and €60 sale price give a 25% discount.
- List successive discounts separately. For Stacked discounts, enter percentages such as 20, 10. On €100, the steps are €100 → €80 → €72.
Questions
Why is 20% off followed by 10% off only 28% off?
The second discount applies to the reduced price. On €100, the first saves €20 and the second saves €8, for a total saving of €28.
How do I find the original price?
Divide the sale price by the proportion left after the discount. At 25% off, €75 ÷ 0.75 = €100. A 100% discount leaves no way to recover the original price from the sale price alone.
Does the order of stacked discounts matter?
For pure percentage discounts applied to the same item without intermediate rounding, the final price is the same in either order. Fixed-value coupons, rounding, minimum spends and retailer restrictions can change the checkout result.
