How much body fat do you carry? This body fat calculator uses the U.S. Navy method: your height, neck and waist size, plus hip size for women. A man 180 cm tall with a 40 cm neck and 90 cm waist scores about 18%. The page also shows your fat mass, lean mass and ACE category.
Body fat estimated with the U.S. Navy circumference method (Hodgdon & Beckett 1984). Ranges follow ACE body fat categories.

Men: body fat percentage = 495 ÷ (1.0324 − 0.19077 × log10(waist − neck) + 0.15456 × log10(height)) − 450
Women: body fat percentage = 495 ÷ (1.29579 − 0.35004 × log10(waist + hip − neck) + 0.22100 × log10(height)) − 450
All measurements go in as centimeters. Inches convert first.

For men, the ACE fitness range is 14–17% and average is 18–24%. For women, fitness is 21–24% and average is 25–31%.
It is an estimate, not a scan. Tape measurements and body shape shift the result by a few points. Use it to track change over time.
Women do; the formula uses waist plus hip minus neck. Men do not need a hip measurement.
Yes. Men need at least 2–5% and women 10–13% for basic body functions. Below that, talk to a doctor.
