How Body Fat is Calculated
The Body Fat Calculator uses the U.S. Navy Method, which is one of the most accurate formulas for estimating body fat percentage. It takes into account your gender, age, height, weight, and specific body measurements.
- Waist = Circumference at the narrowest point of your waist
- Neck = Circumference at the narrowest point of your neck
- Height = Your height in inches
- Body Fat % = Estimated body fat percentage
Example: Male, 32 inch waist, 15 inch neck, 70 inch height
Body Fat % = 18.5%
