Discount Calculator
Check a sale price, apply two successive discounts or compare a stacked offer with a single discount. See the price difference and choose the cheaper offer before shipping and taxes.
Use the same currency for all amounts. Shipping, taxes and fixed-value coupons are excluded.
Calculated in your browser. Amounts are rounded to 2 decimal places.
How to Calculate a Discount
A discount is a percentage of the original price. Multiply the price by the discount rate to find the saving, then subtract the saving from the original price.
- 180 × 25 ÷ 100 = 20 saved
- 280 − 20 = 60
Therefore: An item priced 80 with 25% off costs 60.
Stacked Discounts Are Not Added Together
When a second discount is applied after the first, it is taken from the already-reduced price. A 20% discount followed by an extra 10% is a total saving of 28%, not 30%.
Select Stacked for two discounts, or Compare to enter a competing single discount. On a price of 100, 20% then 10% costs 72; a single 30% discount costs 70. The single offer is cheaper by 2.
Check These Details Before Choosing an Offer
The comparison assumes the same original price and currency. A larger discount percentage does not guarantee a lower total when delivery fees, minimum spend or coupon restrictions differ.
| Price 100 | Final price | Effective saving |
|---|---|---|
| 20% off | 80.00 | 20% |
| 20% then 10% off | 72.00 | 28% |
| Single 30% off | 70.00 | 30% |
| 50% then 50% off | 25.00 | 75% |
