Lean body mass calculator assists you to estimate the weight of your body muscles, bones and organs without including the fat; hence improve in keeping track of your fitness. It is a tool that builds on the essential measurements to determine a fat-free mass, which helps in achieving such objectives as muscle building or losing weight.
It is depended on by fitness enthusiasts and health pros to determine progress. It is usually accompanied by related tools, like body fat percentage calculator, which concern the estimation of LBM. You’ll also like the use it got in the fat-free mass formula or estimation of body composition. Fast and accurate, it makes smarter training choices without JIT.

Formula and Method of calculation
The basic method in this Lean Body Mass Calculator is to initially estimate the body fat percentage (BF) by applying proven research equations and the lean body mass (LBM) is determined as: LBM =Weight (1 – BF/100).
For men (from Tran & Weltman, 1988):
BF = -47.371817 + (0.57914807 x waist cm) +( 0.25189114 x hips cm) +( 0.21366088 x iliac cm)- (0.35595404 x weight kg)
For women (from Tran & Weltman, 1989):
Body density = 1.168297- 0.002824 (waist cm)- 0.0000122098 (waist 2 cm)- 0.000733128 ( hips cm)- 0.000510477 ( height cm)- 0.000216161 (age years)
BF% = (495 / density) – 450 (Siri equation)
Figure: A 30 years old man, weighed 80 kg, 175 cm, waist 90 cm, iliac 85 cm, hips 95 cm.
BF% = -47.371817 + (0.57914807 × 90) + (0.25189114 × 95) + (0.21366088 × 85) – (0.35595404 × 80) ≈ 18.5%
LBM = 80 × (1 – 0.185) ≈ 65.2 kg
This approach will guarantee gender-specific science-based precision.

FAQs
What is included in lean body mass?
- It lays over muscles and bones and organs, and water, everything but fat, to see clearly your constitution.
A question of how accurate is this calculator?
- It is based on peer-reviewed formulae at an error of 3-5% which is similar to simple caliper techniques.
Do I need exact measurements?
- Yes ok, but a little tight but not sorely on waist, iliac, hips.
Can it help with weight loss?
- Practically– since LBM controls fat-based loss without loss of muscle.
Is age a factor for men?
- No, the men formula ignores age whereas, in women, it has it to adjust density.
