Calculate Your Lean Body Mass
Lean Body Mass is the measurement of all the parts of your body that aren’t fat. This includes just about anything from bones, muscles, and organs to water and hormones.
Therefore, it takes into account all aspects of your body to give an overall picture of what you look like beyond simply what you weigh on a scale.

Most of the time, people don’t say what percentage of their total body mass is lean, but it’s usually between 60% to 90%.
Instead, the body fat percentage is calculated, which is the opposite and is usually between 10 to 40%.
How to Use Our Lean Body Mass Calculator?
Calculating lean body mass (LBM) is a great way to track not only your body weight, but also your physical health.
For this lean body mass calculator, we’ll be using the Boer formula which is said to be the most accurate.
Depending on your gender, you’ll use a different equation—for men it’s 0.407 × weight [kg] + 0.267 × height [cm] – 19.2, and for women it’s 0.252 × weight [kg] + 0.473 × height [cm] – 48.3.
Even better yet, if you know your fat concentration then you can determine an exact
LBM according to another simple formula: Lean Body Mass = Body Weight – (Body Weight × Body Fat %).
All you have to do is measure your body weight, multiply it by the fat percentage, and subtract that result from your body weight — easy-peasy! Right?
Example: Suppose, a 50-year-old man height 170 cm and weight 70 kg. Then the person’s lean body mass is 54.68 kg.
LBM Calculator Formula
There are two formulas you consider, according to Wikipedia.
The Boer formula is:
For women: LBM = (0.252 × W) + (0.473 × H) − 48.3
For men: LBM = (0.407 × W) + (0.267 × H) − 19.2
W = body weight in kilograms
H = body height in centimeters.
Hume Formula :
For men: LBM = (0.32810 × W) + (0.33929 × H) − 29.5336
For women: LBM = (0.29569 × W) + (0.41813 × H) − 43.2933
