Body Fat Percentage Calculator: US Navy Method for Accurate Results

Use three tape measurements—waist, neck, and (for women) hip—plus height to estimate body-fat with the U.S. Navy formula. Healthy ranges sit between 14-24 % for men and 21-31 % for women (ACE, 2019). Enter your data, hit “Calculate,” and the script returns a percentage within ±4 % of DXA scans (Hodgdon & Beckett, 1984).
