Calculate your Basal Metabolic Rate (BMR).
The BMR calculator (Basal Metabolic Rate) calculates the amount of energy your body uses at complete rest – just breathing, heart beating, and maintaining bodily functions. It is the basis for all calorie requirement calculations.
The calculator is completely free, works directly in your browser, and does not store personal information. All calculators on this site are based on up-to-date data.
BMR (Mifflin-St Jeor, male) = 10×W + 6.25×H − 5×A + 5. For females: − 161 at the end.
Enter your measurements into the calculator fields and press the calculate button – the result will be displayed immediately. You can try different values to compare various scenarios.
Male, 40 years old, 85 kg, 180 cm → BMR = 10×85 + 6.25×180 − 5×40 + 5 = 850 + 1125 − 200 + 5 = 1,780 kcal/day.
The result is an estimate – for precise clinical measurements, consult a healthcare professional.
The calculator is suitable for self-monitoring health, planning workouts, and general health literacy. Tracking values over time provides valuable information about changes in the body.
Remember that a single measurement result does not tell the whole story – what matters more is the direction and trend over multiple measurement periods.
