Find the sale price and savings for any discount.

This tool runs entirely in your browser. Your files are never uploaded to a server.

100.00

Original price

20.00

Amount saved

80.00

Final price

Enter a non-negative original price and one discount percentage to subtract price × rate / 100 and show the amount saved and final price. In reverse mode, enter the discounted final price and the tool divides it by 1 − rate / 100 to estimate the original and discount amount. It accepts plain numbers without a currency and does not stack discounts, apply tax or enforce a rate range; a 100% reverse rate can therefore produce a non-finite result. Use sensible inputs and verify checkout rounding. Calculation stays local.

Frequently Asked Questions

Can I stack multiple discounts?

Does it work for any currency?
Yes, it's currency-agnostic — just enter the numbers.
