Discount Calculator

How to calculate discount price

A 25% discount on a price of 100 saves 25, leaving a sale price of 75. Multiply the original price by the remaining percentage to calculate the amount to pay.

Formula

price × (1 − discount ÷ 100)

Worked example

Original price

100

Discount (%)

25

Applying the formula to these values gives 75 .

What should I check?

Successive discounts do not add together: 20% off followed by 10% off leaves 72% of the original price.
