Body Fat Percentage Calculator

The US Navy method is a body fat percentage estimation formula developed by the US Navy that uses waist, neck, height (and hip for women) measurements. It does not require caliper measurement and provides results with a 3-4% margin of error.

14-18% for men and 21-25% for women is considered healthy. These percentages may be lower for athletic individuals. Very low body fat percentages should also be approached with caution as they can lead to hormonal imbalances.

Creating a calorie deficit, strength training, and adequate protein intake are the most effective ways to reduce body fat percentage. Targeting 0.5-1% body weight loss per week minimizes muscle loss.
