Everything you need to know about our free fitness tools and how they can help you.
BMR stands for Basal Metabolic Rate, which is the number of calories your body burns at rest to perform basic life-sustaining functions like breathing and circulation. Knowing your BMR is the first step in any diet or fitness plan as it helps you determine your minimum calorie needs before accounting for exercise.
Our calculator uses a scientifically validated formula, such as the Mifflin-St Jeor equation. You simply input your age, gender, height, and weight, and the calculator provides an estimated BMR value.
While our BMR calculator uses the most accurate available formula, it provides a strong estimate. Factors like genetics, lean body mass, and hormone levels can cause individual variations. For a precise measurement, professional lab testing is required.
BMR is the calories you burn at rest. TDEE (Total Daily Energy Expenditure) is your BMR plus the calories you burn from all physical activity throughout the day. Your TDEE is the number you should use for setting daily calorie goals.
Yes, absolutely. Your BMR is the starting point for any goal. Once you know your BMR, you can use our TDEE calculator to find your maintenance calories, and then add a calorie surplus to safely and effectively gain weight.
We recommend recalculating your BMR every time you experience a significant change in body weight (e.g., a gain or loss of 5-10 lbs). This ensures your calorie targets remain relevant to your current body composition.
Standard BMR formulas primarily use height, weight, age, and gender. They do not directly account for muscle mass, which is why a very muscular person may have a higher BMR than the calculator estimates. For a more precise figure that includes activity, use our TDEE calculator.
Our BMR calculator is a free, powerful tool that uses the same formulas professionals use. It's a great substitute for a professional consultation for basic calorie needs, allowing you to start your fitness journey without the cost.
