Discount Calculator
Enter the original price and the discount percentage to instantly see the final sale price and how much you save. There's even a second discount field for "extra % off" deals.
How to calculate a discount
Multiply the original price by the discount percentage to get the amount saved, then subtract it. For 25% off $80: 80 × 0.25 = $20 saved, so you pay $60. This tool does it instantly and also shows the total percentage off.
Stacked ("extra % off") discounts
A common trick: "50% off, then an extra 20% off" is not 70% off. The second discount applies to the already-reduced price. 50% of $100 is $50; another 20% off $50 is $40 — a total of 60% off, not 70%. Enter both percentages above and the calculator handles the stacking correctly.
