A lean body mass calculator estimates how much of your body weight comes from everything except fat, such as muscle, bone, water, and organs.

Lean body mass is your total weight minus fat mass. It gives a better picture of body composition than weight alone.

This calculator uses your gender, height, and weight to estimate lean body mass using a standard formula.

Lean body mass can help you understand your physique better and can be useful when planning fitness, nutrition, and calorie goals.

No. Lean body mass includes muscle, but it also includes bones, organs, and body water.

This calculator gives an estimate, not an exact measurement. For more accuracy, lab or scan-based testing is needed.
