Discount Calculator
Free discount calculator. Enter a price and a percentage off to find the sale price and the amount you save, or work out the percentage discount from two prices.
Work out any discount
Two modes in one tool. Enter an original price and a percentage off to get the sale price and how much you save, or enter the original and sale prices to find the percentage discount.
Stacking and tax
This calculator works on a single discount before tax. For two stacked discounts, apply them one at a time (the second percentage comes off the already-reduced price, not the original). Add sales tax afterward with our sales tax calculator.
