Calculate your lean body mass (LBM), fat-free mass, and estimated body fat percentage using your height, weight, and gender.
Lean Body Mass (LBM) refers to the total weight of your body excluding fat. It includes muscles, bones, organs, body water, and other non-fat tissues.
This calculator uses the Boer Formula, a commonly accepted equation for estimating lean body mass in men and women.
LBM = (0.407 × weight) + (0.267 × height) − 19.2
LBM = (0.252 × weight) + (0.473 × height) − 48.3
This calculator is useful for gym users, athletes, bodybuilders, personal trainers, weight loss users, and anyone interested in body composition analysis.
Fat-Free Mass (FFM) is another term often used interchangeably with Lean Body Mass. It represents all non-fat components of the body.
Healthy lean body mass varies by gender, age, fitness level, and genetics.
