# Discount Calculator Work out the final price and how much you save after one or two discounts — with quick presets. Runs entirely in your browser. ### How it works The first discount is taken off the original price; an optional second discount is applied to *that* reduced price (how “an extra 10% off sale items” actually works), so two 20% cuts give 36% off, not 40%. The **effective discount** is the total saving as a share of the original. Everything is computed locally. --- *Source: [ocxly.com/discount-calculator.html](https://ocxly.com/discount-calculator.html) — OCXLY, free 100% client-side privacy-first tools.
