Work out a sale price in seconds
Shopping a sale? This discount calculator shows the price after the discount and how much you save. Enter a percentage off (“30% off”) or a fixed amount off, and add an extra discount or sales tax if the shop applies one.
How to calculate a discount
Sale price = original price × (1 − discount ÷ 100). For example, 30% off 80 is 80 × 0.7 = 56, a saving of 24. Two discounts are applied one after the other, so “20% off, then an extra 10%” is a 28% discount in total, not 30%.
Questions
Is 20% + 10% off the same as 30% off?
No. The extra 10% comes off the already reduced price, so the total discount is 28%. The calculator shows the true total discount.
Is tax added before or after the discount?
Usually after: tax is charged on the price you actually pay. That's how this calculator works.
