What is Body Fat Calculator?
Body fat percentage is the proportion of fat tissue in your body relative to total body weight. The U.S. Navy method estimates body fat using circumference measurements — waist and neck for males, plus hip for females — along with height. It's a practical, non-invasive alternative to methods like DEXA scans or hydrostatic weighing. Body fat categories differ by gender: for males, 6–13% is Athletic, 14–17% is Fitness, 18–24% is Average; for females, 14–20% is Athletic, 21–24% is Fitness, 25–31% is Average.
How to Interpret Your Results
Body fat categories for males: Essential fat (2–5%), Athletic (6–13%), Fitness (14–17%), Average (18–24%), Obese (25%+). For females: Essential fat (10–13%), Athletic (14–20%), Fitness (21–24%), Average (25–31%), Obese (32%+). Maintaining body fat in the Fitness or Average range is generally associated with good health outcomes.
