FFMI Calculator
The Fat-Free Mass Index (FFMI) measures how much muscle you carry relative to your height — like BMI but for lean mass instead of total weight. Enter your weight, height and body-fat percentage to get your FFMI and the height-normalized FFMI used to compare people of different heights. A normalized FFMI around 25 is often cited as the approximate upper limit for a drug-free, well-trained man (about 22 for women), so it is widely used to gauge muscular potential.
