About this tool
The body fat calculator estimates the share of your body weight that is fat:
- US Navy formula: based on waist, hip and height measurements
- Separate formulas: men and women use different equations and standards
- BMI estimate: the Deurenberg equation for a rough figure
- Four bands: low, standard, high and obese
- Lean mass: the weight left after fat is removed, covering muscle, bone and organs
When to use it
- Tracking fitness progress more accurately than scale weight
- Assessing risk, since high body fat is linked to cardiovascular disease
- Setting a target body fat percentage
- Understanding whether you are skinny-fat or muscular
Reference ranges
- Men: 6 to 13% athletes, 14 to 17% fit, 18 to 24% normal, 25% and above obese
- Women: 14 to 20% athletes, 21 to 24% fit, 25 to 31% normal, 32% and above obese
- Essential fat: 2 to 5% for men and 10 to 13% for women, needed for normal physiology
- Accuracy: formula estimates carry about a 3% error either way; DEXA is the reference method
