Built for People Who Hate Bad Calculators
We got tired of ugly, outdated calculator sites. So we built something better.
Why Kalcufy Exists
Ever searched for a simple loan calculator and ended up on a site that looks like it was built in 2005? Covered in ads, confusing to use, and completely broken on mobile?
Yeah, us too. And it drove us crazy.
Kalcufy was created by developers and financial analysts who use calculators daily—and were frustrated by how unreliable and confusing most of them are. We built a focused set of tools that are actually useful, beautifully designed, and work perfectly on any device.
Built on Trusted Standards
Every calculator is developed using industry-standard formulas and verified sources.
Financial Standards
Our financial calculators use formulas commonly employed by banks, credit unions, and certified financial planners.
Government Data
Tax and retirement calculators reference publicly available data from the IRS, Social Security Administration, and other official sources.
Health Guidelines
Health calculators follow guidelines from recognized organizations including WHO, CDC, and peer-reviewed medical research.
Regular Updates
We continuously review and update our tools to ensure accuracy with current rates, regulations, and best practices.
Important: Kalcufy is designed for educational and informational purposes. Our tools do not replace professional financial, medical, or legal advice. Always consult qualified professionals for important decisions.
