Discount Calculator

What it does

Work out the exact savings on any sale price in seconds. Forward mode takes an original price and a discount percent and shows the final price plus how much you save. Reverse mode takes an original and a sale price and tells you the effective discount percent — handy for comparing ambiguous promos.

All math runs locally, with no tracking. Pair with tax calculator to add sales tax to a discounted price, or margin calculator when you're setting the discount yourself as a seller.

How to use it

1. Enter the original price.
2. Enter the discount percent (or pick reverse mode).
3. Read the final price and total savings.
4. In reverse mode, input the sale price to learn the real discount rate.
