How it works
Your estimated body fat percentage is calculated. Body fat percentage provides a more detailed view of body composition than BMI because it estimates how much of your body weight comes from fat tissue versus lean mass.
This calculator uses the US Navy body fat formula, which combines neck, waist and hip (for women) measurements with height to produce an estimate. It's widely used for fitness assessments and provides a good baseline, but it is still an estimate.
For the most accurate measurement, methods such as DEXA scanning, hydrostatic weighing or skinfold calipers performed by a trained professional will give more precise results.
