Notes to keep in mind
Body fat percentage estimates how much of your total body weight comes from fat tissue. It helps you distinguish between body size and body composition.
That makes it more helpful than BMI alone for muscular adults, active people, and body recomposition goals.
This calculator uses the U.S. Navy circumference method. It estimates body fat from height, neck, waist, and for women, hip measurements.
Results are useful for trend tracking, though small measurement errors can change the estimate.
Healthy ranges vary by sex, age, and athletic background. Use the result as context, not as a strict label.
