Body Fat Calculator

The US Navy method uses neck, waist, and hip measurements combined with height to estimate body fat. It's accurate to within 3-4% of DEXA scan results.

For men, 6-24% is generally healthy. For women, 16-30% is healthy. Athletes tend to have lower percentages, while higher percentages indicate increased health risks.

Body fat percentage is more informative because it distinguishes between fat mass and muscle mass. A muscular person may have a high BMI but a healthy body fat percentage.
