Discount Calculator
Use this calculator for percent off. Find the sale price from an original and a discount, the discount percent from two prices, or the original price from a sale amount and a percent off.
How this is calculated
A discount is a percent of the original price, subtracted from that price. Finding the original from a sale price is reverse percentage with a decrease.
sale = original × (1 − discount / 100)
- 15% of 200 is 30, so the sale price is 200 − 30 = 170.
- From original 80 and sale 68, the discount is (80 − 68) / 80 × 100 = 15%.
- From sale 170 and 15% off, the original is 170 / 0.85 = 200.
This uses the percent-of formula for the savings, then subtracts. It is not markup, which divides extra amount by cost.
Not the same as
A discount is percent off a selling price. These tools measure different gaps.
- Markup Markup is the extra amount relative to cost, not a cut from a list price. Open the markup calculator
- Percentage change Change measures any original-to-new move. Discount keeps shopping labels and can also recover the original price. Open percentage change

170. You save 30.
15%. (80 − 68) / 80 × 100 = 15.
200. Divide 170 by 0.85.
Yes, when the original price is the starting value. Percentage change reports that decrease without a savings line.
Discount cuts a price. Markup adds to cost. Cost 100 to price 150 is markup, not a discount.
100% off makes the sale price 0. Recovering an original from 100% off is not possible, because the factor would be zero.
