Discount Calculator

Discount Calculator is a free tool that runs entirely in your browser, with no data ever sent to a server. Calculate a price after discount and the amount saved.

What it's for

Check a discount advertised in a store, compare two offers, or quickly calculate the final price of a sale item.

What this tool does not do

This tool only applies the calculation described, with no check on the context of use. No limit is set by the tool itself; the only constraint is your device's memory.

Frequently asked questions

How do you combine two successive discounts?

Two discounts don't add up: a 20% discount followed by a 10% discount equals a total discount of 28%, not 30%, because the second one applies to the already-reduced price.

Is my data sent to a server?

No: the amounts you enter are processed entirely in your browser, on your device. They are never transmitted to a server.

Do I need to create an account or install anything?

No: the tool works directly in this page, with no sign-up and nothing to install.
