How it works
sale price = price × (1 − discount ÷ 100)you save = price × discount ÷ 100
- price
- the original or list price
- discount
- the percent taken off
- sale price
- what you actually pay
Two discounts do not simply add up. A 20% coupon on top of a 30% sale is not 50% off, because the second cut comes off the already lowered price: $100 becomes $70, then $56, an effective 44% off.
Frequently asked questions
What is 25% off $60?

How do I calculate a sale price?
Multiply the price by 1 minus the discount as a decimal. For 25% off, multiply by 0.75.
What is 40% off $80?
$48. The saving is $32.
Do stacked discounts add together?
No. A second discount comes off the reduced price, so 30% then 20% is 44% off overall, not 50%.
