How to use

  3. To find the discount from two prices, switch to the «Increase or decrease» tab and enter the old and the new price.

Good to know

Two discounts in a row are not their sum

«30% off, then another 20% at the till» is not 50%. The second discount applies to the already reduced price: 100 becomes 70, then 56 — a total of 44%. That gap is exactly where the sign gets its persuasive power.

Checking the claimed discount

If the tag shows the old and the new price, the honest percentage is (old − new) ÷ old. The «Increase or decrease» tab does it for you — a useful check when the shop rounds the number in its own favour.

Frequently asked questions

How do I calculate the price after a discount?

Enter the price and the percentage: the tool multiplies by (100 − discount) ÷ 100 and shows the amount you actually pay.

How do I find the discount from two prices?

Use the «Increase or decrease» tab: old price first, new price second. The answer is the real discount percentage.

How do I stack two discounts?

Apply them one after the other: subtract the first, then take the result and subtract the second.
