About Us
About WellCalc
Our mission: make professional-grade health tools free and accessible to everyone — no logins, no paywalls, no data collection.
WellCalc was built for one simple reason: high-quality health calculators should be free for everyone. We believe that access to accurate health information shouldn't depend on your income, location, or insurance coverage.
Our Mission
WellCalc exists to give everyone — regardless of where they live or what they can afford — access to the same quality health tools used by healthcare professionals. Every calculator on our site uses clinically validated formulas sourced from organisations including the WHO, American Heart Association, NHS, and peer-reviewed medical journals.
We serve readers primarily in the United States, United Kingdom, Canada, Australia, and New Zealand — countries where English is the primary language and access to preventive health tools can make a real difference in daily health decisions.
What Makes WellCalc Different

Clinically Validated

Important Limitations
WellCalc is an educational tool, not a clinical service. Please be aware that:
- Calculator results are estimates based on population averages — not personalised clinical measurements
- Results should never replace a consultation with a qualified healthcare professional
- Medical guidelines and reference ranges vary between countries and are updated periodically
- If you have any health concerns, please consult your GP (UK/AU/NZ) or primary care physician (USA/Canada)
