Discount calculator
Sale price and savings after a percentage off.
About this calculator
Enter the original price and the percentage off to see what you pay and what you save.
For two discounts in a row, run the sale price through again. A 20% discount followed by 10% off is 28% off in total, not 30%.
How it works
The saving is the price times the discount. Subtract that from the original price.
Worked example
- Original price: $120
- Discount: 25%
Sale price: $90.00
The story behind it
Percent-off sales are easy to read and easy to misjudge. Two discounts in a row feel like they should add up, yet 20% off followed by 10% off is 28% off, not 30%. This calculator is for that moment in a shop or at an online checkout: enter the price and the percentage, and see what you'd actually pay and save.
