Reverse Calculator — What discount % reaches a target price?
Enter an original price and the sale price you want to reach, and we will find the required discount percentage.
Required Discount
Quick answer
Sale price = original price × (1 − discount ÷ 100). An $80 item at 25% off costs $60, so you save $20, and with 8% sales tax the total is $64.80. Stacked discounts multiply rather than add: 20% off and then 10% off is 28% off, not 30%.
Examples
| Price | Discount | Sale price | You save |
|---|---|---|---|
| $80.00 | 25% | $60.00 | $20.00 |
| $49.99 | 30% | $34.99 | $15.00 |
| $250.00 | 15% | $212.50 | $37.50 |
| $100.00 | 20% + 10% | $72.00 | $28.00 |
Enter your price and discount, including a second stacked one.
