About this tool
This page opens the body fat calculator with sex preselected to female, which reveals the extra hip-circumference field the women's formula needs alongside height, neck and waist — the calculator adapts its own form the moment sex is set, so you see exactly the four fields required and nothing else.
Women typically carry more essential fat than men and store it differently, so the US Navy formula for women uses waist plus hip minus neck rather than the men's waist-minus-neck calculation. Measure the waist at its narrowest point and the hips at their widest point for a measurement that matches how the formula was validated.
The result is classified on the ACE scale for women — essential fat at 10–13%, athletes at 14–20%, fitness at 21–24%, average at 25–31% and obese at 32% and above — and entering your weight additionally splits it into fat mass and lean mass in kilograms.
Example. Male measurements of 180 cm height, 38 cm neck and 90 cm waist display 19.8%.
Limit. Height must be 80–250 cm, the male formula requires waist greater than neck, the female formula also requires hip, and a result outside 0–75% is rejected.
