Calculator Inputs
Live Real-TimeEstimated Body Fat Percentage
Lean Body Mass (LBM)
63.2 kg
Total Fat Mass

Lean Body Mass vs Fat Mass
Detailed Calculation Breakdown
Calculation Methodology
Body Fat % = (1.20 * BMI) + (0.23 * Age) - (16.2 for Males / 5.4 for Females). Fat Mass = Weight * (Body Fat % / 100). Lean Mass = Total Weight - Fat Mass.
