Discount calculator

How it works

Enter the original price and the discount percentage to see the sale price and how much you save.

The formula

Sale price = price × (1 − discount ÷ 100). Saving = price − sale price.

Worked example

A 25 item at 30% off: 25 × 0.70 = 17.50, so you save 7.50.

Good to know

• Two discounts in a row multiply, they do not add: 20% then 10% off is 28% off, not 30%.
• If tax is added at the till, apply the discount first, then the tax.
