Calculate your Basal Metabolic Rate (BMR) - the number of calories you burn at rest
A BMR calculator is a health and fitness tool that helps you calculate your Basal Metabolic Rate (BMR). BMR represents the number of calories your body needs each day to perform essential functions such as breathing, circulation, and maintaining body temperature while at complete rest.
This calculator uses your gender, age, height, and weight to estimate your BMR using a scientifically accepted formula. You can enter height in centimeters or feet and inches, and weight in kilograms or pounds to get accurate results.
Knowing your BMR helps you understand how many calories your body needs to function at rest. It forms the foundation for calculating total daily calorie needs and planning weight loss, weight gain, or maintenance goals.
BMR measures calories burned at rest, while your actual daily calorie needs depend on physical activity, exercise level, and lifestyle. BMR is the starting point for determining your total daily energy expenditure.
No. BMR varies based on age, gender, height, weight, and body composition. Each person has a unique metabolic rate.
Yes. BMR can change with age, weight changes, muscle gain or loss, and overall health.
This calculator provides a reliable estimate based on standard formulas, but actual calorie needs may vary. For medical advice, consult a healthcare professional.
BMR (Basal Metabolic Rate) is the number of calories your body needs to perform basic life-sustaining functions like breathing, circulation, and cell production. This calculator uses the Mifflin-St Jeor Equation, which is considered one of the most accurate BMR formulas.
BMR is just one component of your total daily energy expenditure. Your actual calorie needs will be higher based on your activity level. Consult with a healthcare professional or nutritionist for personalized advice.
