Who pays for this site?

Nobody who visits it. Calculate-Percentage.com has no ads: no banners, no pop-ups, no video that starts playing in the corner.

Most free calculator sites pay their bills with ads. You've probably seen the result: a calculator squeezed between banners, the page jumping while ads load, and a video player covering the answer you came for.

We chose a different deal. The site is kept running by two products we build ourselves. They pay for hosting and for our time, so this page can stay fast, keep the calculator in plain view and just give you the number.

Scanlo shows how many times each code was scanned. Visit Scanlo →

If you run a business and either of them sounds useful, trying it is the best way to support this site.
