Our Story

Built for People Who
Take Their Health Seriously

HealthCalc was created to give everyone access to accurate, science-backed health tools — without paywalls, sign-ups, or complexity.

Our Mission

We believe that understanding your own body shouldn't require a medical degree or an expensive subscription. Health literacy is one of the most powerful tools a person can have — and it should be free.

HealthCalc was built with a single purpose: to make accurate, research-backed health calculators available to everyone, everywhere, on any device. Whether you're tracking your weight loss progress, planning a pregnancy, or simply curious about how many calories your body actually needs, our tools give you clear, actionable answers in seconds.

Every calculator on this site is based on peer-reviewed medical formulas and guidelines from organizations like the WHO, AHA, NHS, and CDC. We don't simplify the science — we make it accessible.

From BMI to diabetes risk — we have you covered.

Our Commitment to Accuracy

Health misinformation is a serious problem online. We take accuracy seriously. Every calculator on HealthCalc uses the same equations that healthcare providers use in clinical settings.

For example, our BMI Calculator uses the standard WHO formula. Our Calorie Calculator uses the Mifflin-St Jeor equation — the most accurate BMR formula validated for modern populations. Our Diabetes Risk Calculator is based on the FINDRISC questionnaire, validated in multiple European population studies.

Where results touch on medical decisions, we always include a clear disclaimer encouraging users to consult a healthcare professional. We are a supplementary information resource, not a replacement for medical care.

A Note on Medical Advice

HealthCalc is an educational resource. Our calculators provide estimates and general guidance based on population-level research. They cannot account for your individual medical history, medications, genetics, or other personal factors that a doctor would consider.

If you have health concerns, or if any result here worries you, please speak with a qualified healthcare professional. Our goal is to empower you with information — not to replace the medical care you deserve.
