Calculate discounts

How to use the discount calculator

1. Enter the original price.
2. Enter the discount percentage and, if any, an extra second discount.
3. Review the final price, the saving and the total effective discount.

Discount formula

Final price = price × (1 − d1) × (1 − d2)

What each variable means

d1, d2

discounts as decimals

Two discounts in a row don't add up: 20% then another 10% equals 28%, not 30%.

Discount example

An €80 item with a 25% discount costs €60: you save €20.

Illustrative example with the data shown; not a guaranteed outcome.

Assumptions and limitations

• The second discount applies to the already reduced price.
• Taxes are not added if the price excludes them.
