BMR Calculator
Estimate how many calories your body burns at rest daily.
Calculate Your BMR
Introduction
Your Basal Metabolic Rate (BMR) is the number of calories your body needs to perform its most basic, life-sustaining functions, such as breathing, circulation, and cell production, while at rest. Knowing your BMR is the first step in understanding your total daily calorie needs and is a fundamental component of any effective weight management plan.
How Our BMR Calculator Can Help You
Our BMR Calculator provides the foundational number for your entire nutritional strategy. By understanding your baseline calorie burn, you can make informed decisions about your diet. For weight loss, it helps you set a safe and effective calorie deficit. For muscle gain, it ensures you're eating enough to fuel growth without accumulating excess fat. It removes the guesswork from the "eat less, move more" mantra by giving you a concrete number to work with. This personalized data is far more effective than relying on generic calorie targets, as it's tailored to your specific body composition and age.
How It Works
The calculator uses the revised Harris-Benedict equation, a trusted and scientifically validated formula, to estimate your BMR. It takes into account your weight, height, age, and gender—all key factors that influence your metabolic rate. For instance, muscle mass (generally higher in men and younger individuals) burns more calories at rest than fat. The calculator processes these inputs through the formula to provide an accurate estimate of the calories you would burn if you were to stay in bed all day. This number is your metabolic baseline.

FAQs About Our BMR Calculator
What's the difference between BMR and TDEE?
BMR is your calorie burn at complete rest. TDEE (Total Daily Energy Expenditure) includes your BMR plus the calories you burn from all physical activity.
Why is my BMR different from my friend's?
BMR is highly individual and depends on factors like age, gender, weight, height, and body composition. No two people will have the exact same BMR.
Can I increase my BMR?
Yes! Building more muscle mass through strength training is one of the most effective ways to increase your BMR, as muscle tissue burns more calories at rest than fat tissue.
How accurate is this calculation?
The formula provides a very good estimate for most people. However, for the most precise measurement, a clinical test called indirect calorimetry would be required.
