Body Fat Percentage Calculator

Body fat percentage is a more accurate measure of health and fitness than BMI alone, as it distinguishes between fat mass and lean mass (muscle, bone, and organs). Our body fat calculator uses the US Navy circumference method, which estimates body fat from measurements of the neck, waist, and hips (for women). This method has been validated in research and is widely used by fitness professionals. For men, a healthy body fat range is typically 10–20%; for women, 18–28%. Athletes often have lower body fat percentages, while values above 25% (men) or 32% (women) are generally considered in the obese range. Use this calculator alongside BMI and other health metrics for a fuller picture of your health.
