When two discounts like 20% and 10% are applied one after another, the total savings is not 30%. The second discount applies to the already-reduced price, so a value of 100 becomes 80 after 20% off, then 72 after another 10% off — a combined discount of 28%, not 30%. This calculator handles that math correctly.
| Discount | You Pay | You Save |
|---|---|---|
| 10% off | 90% of price | 10% of price |
| 20% off | 80% of price | 20% of price |
| 25% off | 75% of price | 25% of price |
| 30% off | 70% of price | 30% of price |
| 50% off | 50% of price | 50% of price |

Multiply the original price by (1 minus the discount percentage divided by 100). For example, 80 with 25% off is 80 × (1 − 0.25) = 60. Use the "Final Price" tab above.
Subtract the sale price from the original price, divide by the original price, then multiply by 100. For example, an item priced at 80 on sale for 60 has a discount of ((80−60)÷80)×100 = 25%.
Divide the sale price by (1 minus the discount percentage divided by 100). For example, a sale price of 60 with 25% off means the original price was 60 ÷ 0.75 = 80.
No. Stacked discounts apply one after another, not added together. A value of 100 becomes 80 after 20% off, then 72 after another 10% off — a combined discount of 28%, not 30%.
