Enter the original price and discount percentage to see the final price and your savings.
A percentage discount reduces the price by that fraction of the original. Subtract the discount amount from the original price to get the final (sale) price. The amount saved is simply original minus final.
To calculate a discount, multiply the original price by the discount percentage divided by 100, then subtract that amount from the original price. Example: a $120 item with a 15% discount has a discount amount of $120 x 0.15 = $18, so the final price is $120 minus $18 = $102.
30% off 15,000 is 10,500 (you save 4,500).
20% off $80 is $64 (you save $16).
The original price was 20,000 (12,000 ÷ (1 − 0.40) = 20,000).
25% off 200 is 150 (you save 50).
50% off 40 is 20 (you save 20).
The original price was 120 (96 ÷ (1 − 0.20) = 120).
The original price was 100 (90 ÷ (1 − 0.10) = 100).
You save 18 (120 × 0.15 = 18), for a final price of 102.
| Original price | Discount | Discount amount | Final price |
|---|---|---|---|
| $50 | 20% | $10.00 | $40.00 |
| $120 | 15% | $18.00 | $102.00 |
| $85 | 30% | $25.50 | $59.50 |
| $200 | 10% | $20.00 | $180.00 |
| $75 | 25% | $18.75 | $56.25 |
Subtract the final price from the original price to get the discount amount, divide that by the original price, then multiply by 100. For example, a price drop from $120 to $102 is an $18 / $120 x 100 = 15% discount.
Each discount applies to the price remaining after the previous one, not the original price, so two 20% discounts are not the same as one 40% discount. A $100 item with two successive 20% discounts becomes $80, then $64, an effective discount of 36%, not 40%.
No. This tool only applies the discount percentage to the original price. If tax is charged on the discounted amount, add it separately after computing the final price shown here.
The discount amount is a currency value, like $18, while the percentage saved expresses that same amount relative to the original price, like 15%. Both describe the same reduction in different units.
This calculator performs simple percentage arithmetic and does not account for sales tax, shipping fees, coupon stacking rules, or currency conversion. Retailers may calculate percent off differently for bundled or tiered pricing, so always confirm the final price at checkout.
