About HealthCalc

Our Mission

HealthCalc was built with one simple goal: make health metrics understandable and accessible to everyone. Too many people hear terms like BMI, TDEE, and body fat percentage but have no way to actually calculate or interpret them without paying for an app or visiting a clinic.

We believe basic health metrics should be free, instant, and easy to understand. That's why every calculator on this site is completely free, requires no account, and delivers results the moment you click calculate.

What We Offer

Our free online calculators help you with:

• BMI Calculation — Understand your Body Mass Index and what it means for your health
• Calorie & TDEE Tracking — Find your daily energy expenditure for effective weight management
• Body Composition — Estimate body fat percentage with the US Navy method at home
• Pregnancy Tracking — Calculate your estimated due date using the clinical standard method
• Hydration Planning — Find your optimal daily water intake based on your body

Why Use HealthCalc?

Unlike other health tools that hide features behind paywalls or require lengthy sign-ups, HealthCalc offers:

• 100% Free — No premium tiers, no hidden fees, no subscriptions
• No Sign-Up Required — Use any calculator instantly, no account needed
• Privacy First — All calculations happen locally in your browser. Your data never leaves your device
• Mobile Friendly — Works perfectly on any device
• Instant Results — No loading, no servers to query — just fast JavaScript calculations

How We Make Money

HealthCalc is supported by advertising. We display relevant, unobtrusive ads from reputable advertising networks. We do not sell your personal data, and no calculator inputs are ever collected or stored.

Important: All calculators on HealthCalc are for educational and informational purposes only. They are not substitutes for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional for personalized health guidance.

The Team

HealthCalc was created by a small team of developers and health enthusiasts who were frustrated with the lack of free, accurate health tools online. We build and maintain this site in our spare time, driven by the belief that everyone deserves access to basic health information.
