Body composition calculator

Body Composition Calculator

Your body composition - the percentage of fat and lean mass (non-fat) is an important anthropometric measure of your health. There are several methods to calculate body fat percentage, such as DEXA scans, biological impedance analysis and more. The US Navy uses a simpler method to assess body composition, using measures of your height, weight, waist circumference, neck circumference and hip circumference. While not entirely accurate - the estimated error level is 3-4% compared with the results indicated - this is a quick and inexpensive way to get an initial assessment of your body composition.
