About Health Calculators

Health Calculators gives you simple, free tools to understand common health numbers — BMI, calorie needs, body fat estimates, and heart rate zones.

Every calculator on this site runs entirely in your browser. You do not need an account, and the numbers you type in are never sent to our servers. Each page explains what the result means, where the estimate can mislead, and sensible general next steps — and reminds you to talk to a healthcare professional before making health decisions.

These tools are educational. They estimate, they do not diagnose, and they are not a substitute for professional advice, testing, or care.

Who runs this site?

Health Calculators is a free website by UMARIX TECHNOLOGIES (SMC-PRIVATE) LIMITED, a software company that builds practical web tools and business software. Everything on this site is free to use, works right in your browser, and requires no sign-up.
