Discount calculator
Enter the original price and the discount percentage to get the final price and the amount saved. You can add sequential discounts, such as a seasonal sale followed by a coupon, and see the real single discount they equal. It works as a percent-off calculator for sales, coupons and price tags.

How to use it
- Enter the original price before any discount.
- Enter the discount percentage, between 0 and 100.
- If a second discount is applied after the first, press “Add another discount” and enter its percentage. An empty field is ignored.
- Read the final price, the savings and the equivalent single discount, and copy the result if you like.
Example
A price of 200 with a 15% discount: the discount amount is 200 × 0.15 = 30, so the final price is 170.
A price of 100 with 20% and then 10%: the first discount brings it to 80, the second is taken from 80 and brings it to 72. The equivalent discount is 28%, not 30%.
Limits and caveats
- Sequential discounts are applied in order, each on the price left by the previous one. If your shop adds the percentages together and applies them once, the result is different.
- The tool does not handle tax, shipping or fixed-amount discounts (such as 20 off).
- Up to six discounts can be entered: the main one and five extra. The largest accepted price is 1,000,000,000,000.
- Amounts are displayed rounded to two decimal places, and the displayed savings are the original price minus the rounded final price so the figures add up.
Questions about this tool
Why is 20% then 10% not the same as 30% off?
Because the second discount is taken from the price after the first discount, not from the original price. What remains is 0.80 × 0.90 = 0.72 of the price, so the equivalent discount is 28%.
Does the order of the discounts change the final price?
No. 20% then 10% gives the same result as 10% then 20% because the operation is multiplication. Only the amount taken off at each step changes.
How do I find the discount percentage when I only have the two prices?
Subtract the final price from the original, divide by the original price and multiply by 100. Example: (200 − 170) ÷ 200 × 100 = 15%.
How do I calculate a discount?
Multiply the price by the discount percentage and divide by 100 to get the amount off, then subtract it from the price to get the final price. A price of 250 with 30% off: 250 × 30 ÷ 100 = 75 off, so the price after the discount is 250 − 75 = 175. You can also multiply the price by 0.70 in one step.
How do I find the original price before a discount?
Divide the discounted price by (1 − discount ÷ 100). A price of 175 after 30% off was 175 ÷ 0.70 = 250 before the discount. This discount calculator works forwards from the original price, so enter the result to check it.
