Body Fat Percentage Calculator

This tool estimates your body fat percentage using the US Navy formula

About This Tool

This Body Fat Percentage Calculator helps you estimate your body fat levels using the U.S. Navy Method. This considers key body measurements such as waist, neck, and hip circumference (for females) to provide an estimate of your body fat percentage.

Tracking your body fat percentage is more insightful than measuring your weight alone. For example, if you're putting on muscle at the the same time as losing fat, your weight may actually stay the same which your health is actually improving. Your body fat percetage level can better help you understand your fitness levels and allow you to track progress over time.

Whether you're aiming for fat loss, muscle gain, or overall health improvement, frequently checking your body fat levels can offer a simple yet effective way to monitor your progress.

As with all health metrics, it should never be used a sole measure of your health or fitness, as other aspects can influence these that are not always reflected in simple calculations.
