Understanding Body Fat Percentage
Body fat percentage (BFP) is the total mass of fat divided by total body mass, multiplied by 100. Body fat includes essential body fat and storage body fat. Essential body fat is necessary to maintain life and reproductive functions.
How the Navy Formula Works
The U.S. Navy method is a popular tool for estimating body fat percentage. It uses measurements of the neck, waist (and hips for women) combined with height. While not as accurate as a DEXA scan, it provides a cost-effective and fairly reliable estimate for most individuals.

For Men:
– Essential Fat: 2-5%
– Athletes: 6-13%

For Women:
– Essential Fat: 10-13%
– Athletes: 14-20%
– Fitness: 21-24%
– Acceptable: 25-31%
– Obesity: 32%+
Measurement Tips
To get the most accurate results from this calculator, ensure you measure correctly:
- Waist: Measure at the narrowest point for women and at the navel level for men.
- Neck: Measure below the larynx, sloping slightly downward to the front.
- Hips (Women only): Measure at the widest point of the buttocks.
