The Fat-Free Mass Calculator determines your fat-free mass (FFM) and fat-free mass index (FFMI). FFM represents your body weight minus all fat, encompassing muscle, bone, organs, and water. FFMI then normalizes this FFM value for your height, providing a more accurate assessment of muscularity compared to simply looking at body weight or BMI. Enter your current weight, height, and body fat percentage to get started.
Your calculated FFM value indicates the total amount of non-fat tissue in your body. The FFMI, however, is the key metric for evaluating muscular development. A higher FFMI generally suggests greater muscularity. For example, an FFMI over 20 for men and 17 for women is often associated with a well-developed physique. These figures offer a baseline for understanding your current body composition.
Use your FFM and FFMI results to inform your fitness journey. If your FFMI is lower than desired, consider focusing on strength training and a protein-rich diet to build muscle. If you're unsure how to interpret your results or want personalized guidance, RPM Gym offers a free guided tour of our facilities. Our expert trainers can discuss your body composition and help you set achievable fitness goals.

While it varies, an FFMI over 20 for men and 17 for women is generally considered indicative of a well-developed, muscular physique. These are general guidelines, and individual goals may differ.
