Lean Body Mass Calculator
Calculate your LBM to better understand your body composition and track progress.
What is Lean Body Mass (LBM)?
Lean Body Mass (LBM) is the weight of your body minus all its fat. It includes the weight of your organs, bones, muscles, and water. Unlike Body Mass Index (BMI), which can be misleading for muscular individuals, LBM provides a more accurate picture of your body composition and is often used as a key metric for fitness and health professionals.
Understanding your LBM is essential for setting personalized fitness goals, especially for those looking to build muscle or lose fat.
Why Track Your LBM?
- It's a more accurate measure of progress than body weight alone.
- It helps you set realistic goals for muscle gain and fat loss.
- LBM is directly related to your basal metabolic rate (BMR).
- It's often used in medical settings to determine medication dosages.
For more in-depth information on LBM and body composition, you can visit authoritative sources such as the National Center for Biotechnology Information (NCBI), Healthline, or the American Council on Exercise (ACE).

Frequently Asked Questions
Body weight is your total mass, including fat, muscle, bone, and water. Lean Body Mass (LBM) is everything except fat. LBM is often a better indicator of health and fitness because it specifically measures muscle mass, which is metabolically active and essential for a healthy body.
This calculator uses the Boer formula to estimate LBM. It is calculated based on your height, current body weight, and gender. The formula is a widely accepted method for providing a quick and reliable estimate of your LBM without needing to measure body fat directly.
LBM is important for fitness because it's a direct indicator of your muscle mass. Gaining LBM is often a primary goal in strength training and bodybuilding. A higher LBM can also boost your metabolism, which helps with weight management. Tracking your LBM allows you to measure muscle gain, not just fat loss, which is a more complete picture of your fitness progress.
