Common questions about body fat percentage
Body fat percentage is a more accurate indicator of health than weight or BMI alone. It helps distinguish between fat mass and lean muscle mass. Healthier body fat levels correlate with reduced risk of chronic diseases.
This calculator uses the U.S. Navy body fat formula, which incorporates height, neck, and waist measurements (and hip measurements for women) to estimate body fat percentage.
Healthy ranges vary by age and gender. Generally, for young adult men (20-39), 8-19% is considered healthy. For young adult women (20-39), 21-32% is considered healthy.
