The full guideMarkup vs margin: the difference, with examples

The formulas

Sale price = original price × (1 − discount). 30% off $80 is $80 × 0.70 = $56.
Percentage off = 1 − (sale price ÷ original price). From $80 to $56 is 1 − 0.70 = 30%.

Two discounts don't add up

"30% off, then an extra 20% at the till" is not 50% off. The second discount applies to the already reduced price: $80 × 0.70 × 0.80 = $44.80, which is 44% off in total. The calculator shows the real total.

For sellers: what a discount costs you

A discount comes straight out of your margin. If your markup is 50%, a 20% discount removes most of your profit on that sale, and you need to sell a lot more just to earn the same. Check it with the profit margin calculator and the guide to markup vs margin.

Frequently asked questions

How do I calculate 30% off?

Multiply the price by 0.70. For 25% off, multiply by 0.75; for 15% off, by 0.85.

How do I find the percentage of a discount?

Divide the sale price by the original price, subtract the result from 1 and multiply by 100. $56 out of $80 is 0.70, so 30% off.

Are two discounts the same as one bigger one?

No: they multiply rather than add. 30% then 20% equals 44% off, not 50%.
