Discount Calculator
Enter a price and a discount to see the final price and how much you save. You can add a second, stacked discount too. It works in any currency. Everything runs in your browser – nothing is uploaded or saved.
Stacked discounts
Two discounts are not added together. They are applied one after the other, so 30% then 10% gives a 37% total discount, not 40%. Final price = price × (1 − d1) × (1 − d2).
