About this tool
This discount calculator shows the sale price and the amount you save for any original price and discount percentage from 0% to 95%.
How to use it
- Choose your currency and enter the original price.
- Drag the slider to the discount percentage.
- Read the sale price and how much you save.
Good to know
- Savings = original price × discount % ÷ 100.
- Sale price = original price − savings.
- Example: 25% off 80 saves 20, for a sale price of 60.
- Two discounts stack multiplicatively: 20% off and then another 10% off is 28% off in total, not 30%.

Frequently asked questions
How do I calculate a discount?
Multiply the price by the discount percentage and divide by 100 to get the savings, then subtract that from the original price. 25% off 80 is 80 − 20 = 60.
How do I combine two discounts?
Apply them one after the other. 20% off 100 is 80, and another 10% off 80 is 72 — a combined 28% discount.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount ÷ 100). A 60 sale price at 25% off came from 60 ÷ 0.75 = 80.
Does the calculator include sales tax?
No. It works on the price you enter; add tax separately if it applies after the discount.
