Engineers, Educators & Designers Dedicated to Mathematical Clarity
Percentage Calculator is an independent digital utility project developed by a dedicated team of software engineers, UX designers, and mathematics educators under Percentage Calculator.
We believe that mathematical utility tools should be as intuitive, accessible, and beautifully designed as the software applications we rely on every day. Our team combines expertise in web performance engineering, localization, and educational pedagogy to make percentage math effortless for students, professionals, and everyday consumers.

Full localization across 18 languages with complete RTL support, enabling users anywhere in the world to calculate in their native language.
Building the Calculator the Internet Deserved
The story of Percentage Calculator began in 2024 when our founding team tried to compute a simple percentage online. We were met with outdated websites from the early 2000s — cluttered with intrusive ads, broken mobile layouts, and slow load times.
We realized that despite percentages being calculated billions of times every day worldwide, the available web tools were neglected and poorly built. We set out to create a modern alternative: a platform that loads in milliseconds, respects user privacy, requires zero account signups, and delivers a premium user experience.
What started as a single calculator quickly grew into a suite of 6 specialized tools serving millions of monthly users across 180+ countries.
Parent Company & Governance
Percentage Calculator is owned and operated by Percentage Calculator, a registered digital publishing and technology company committed to building free, privacy-first web utilities.
As part of Percentage Calculator, our operations are funded through sustainable corporate sponsorship and partner network initiatives, allowing us to keep all calculators 100% free forever for end users without cluttering our interfaces with pop-up advertisements or paywalls.
