How it works

Use this tool with clear assumptions

Use this calculator to verify sale prices, compare offers, or plan retail promotions with clear savings numbers.

The reverse modes are helpful when you know the final price but need to find the discount or original price.

Formula / logic

Sale price = original price - discount amount. Discount amount = original price * discount rate.

Example

A $100 item with 20% off has a $20 saving and an $80 final price before tax.
