About Percentify

Percentify is a free online toolkit for everyday percentage calculations. We built it because percentage math comes up constantly — in shopping, finance, cooking, fitness, and work — and the mental shortcuts are not always obvious. Our goal is to give anyone a fast, no-fuss answer without needing a spreadsheet or remembering a formula.

Our mission

Make percentage calculations instant and accessible for everyone, at no cost and with no sign-up required.

Who we are

Percentify is operated by an independent developer based in Uden, The Netherlands. We focus on building clean, fast, and reliable tools that work for everyone — whether you need a quick answer on your phone or a detailed explanation of how the formula works.
