About CalcFast
Building the world's most accessible calculator platform, one tool at a time.
Our Story
CalcFast was founded in January 2025 with a simple yet powerful vision: to create a calculator platform that respects users' time, privacy, and need for accessibility. After years of frustration with calculator websites cluttered with intrusive ads, confusing interfaces, and poor mobile experiences, our founding team decided to build something better.
What started as a weekend project quickly evolved into a comprehensive platform serving thousands of users worldwide. Today, CalcFast offers 15+ specialized calculators across health, finance, and everyday mathematics, with new tools added regularly based on user feedback and emerging needs.
Our journey has been guided by three core principles: speed (instant results without waiting), privacy (no data collection or tracking), and accessibility (WCAG AA compliant design for everyone). These values continue to shape every decision we make as we grow.
Our Mission
At CalcFast, our mission is to provide lightning-fast, highly accurate, and incredibly accessible online calculators to everyone, everywhere. We believe that getting quick, reliable answers to your everyday questions shouldn't involve navigating through pop-ups, paywalls, or complex interfaces.
Our goal is to empower you to make informed decisions about your health, finances, and daily life with ease and confidence. We're dedicated to creating a user-friendly experience that respects your privacy and works seamlessly across all devices, ensuring that crucial information is always at your fingertips.
Our Team
CalcFast is built and maintained by a dedicated team of developers, designers, and subject matter experts passionate about creating tools that make a difference in people's lives.
Juan is a software engineer with over 10 years of experience in full-stack development, specializing in building high-performance, accessible web applications. With deep expertise in TypeScript, React, Astro, and modern JavaScript frameworks, he founded CalcFast to create the calculator platform he always wanted to use--fast, clean, and truly accessible. His commitment to WCAG compliance and performance optimization drives every technical decision.
Our design philosophy centers on creating intuitive, accessible interfaces that work beautifully across all devices.

We consult with health professionals, financial advisors, and mathematics experts to ensure our calculators use accurate, peer-reviewed formulas and provide reliable results. Every calculator undergoes thorough verification before publication.
