Health Calculators
Health calculators apply widely used estimation formulas — such as the WHO body mass index classification and the Mifflin–St Jeor equation for resting metabolism — to give you a rough reference point.
These formulas describe population averages, not individuals. Results are estimates for general information only and are not medical advice, a diagnosis, or a treatment plan. Always consult a qualified health professional about your personal situation.
Please note
- Results are estimates based on standardized formulas.
- Individual factors (muscle mass, pregnancy, medical conditions, age) can make estimates inaccurate.
- These tools are educational and are not a substitute for professional medical advice.
- BMI CalculatorCalculate body mass index from height and weight, in metric or imperial units, with the WHO classification.
- BMR CalculatorEstimate basal metabolic rate — the calories your body burns at rest — using the Mifflin–St Jeor equation.
- TDEE CalculatorEstimate total daily energy expenditure — maintenance calories — from BMR and activity level.
