Discount Calculator
Enter the original price and the discount to see what you pay.
How it works
The amount saved is the price times the discount percentage, and the sale price is what remains. 20% off $100 saves $20, so you pay $80. Another way to get the sale price directly is to multiply by what you keep: 20% off means you pay 80%, so $100 × 0.80 = $80.

Stacked discounts
"50% off, then an extra 20% off" is not 70% off. The second discount applies to the already reduced price, so $100 becomes $50 and then $40, a total discount of 60%. The table shows the real total for common combinations.
| First discount | then 10% off | then 15% off | then 20% off | then 25% off |
|---|---|---|---|---|
| 10% off | 19% | 23.5% | 28% | 32.5% |
| 20% off | 28% | 32% | 36% | 40% |
| 30% off | 37% | 40.5% | 44% | 47.5% |
| 40% off | 46% | 49% | 52% | 55% |
| 50% off | 55% | 57.5% | 60% | 62.5% |
Finding the original price
If you know the sale price and the discount, divide the sale price by the share you pay. A $60 item that is 25% off was originally $60 ÷ 0.75 = $80.00. If the tag claims a higher "was" price, the real discount is smaller than advertised.
Comparing deals
A bigger percentage doesn’t always mean the better deal. Compare final prices, or the price per unit (per ounce, per item, per use) when the products differ in size. Sales tax, where it applies, is added after the discount; the sales tax calculator works out that part.
