Body Fat Calculator
Estimate your body fat percentage using visual comparison, the U.S. Navy method, or skinfold measurements. Body fat percentage is a more accurate indicator of health and fitness than weight or BMI alone.
Why Body Fat Percentage Matters
Body fat percentage tells you how much of your total body weight is fat versus lean mass (muscle, bone, organs, water). Unlike BMI, which only considers height and weight, body fat percentage provides insight into your actual body composition.
Two people can weigh the same but have very different body fat levels. Someone with more muscle and less fat will typically be healthier, stronger, and have a faster metabolism than someone with the same weight but higher body fat.

Measurement Methods
Our calculator offers three methods to estimate body fat. The visual method is quickest but least precise. The U.S. Navy method uses circumference measurements and is reasonably accurate with proper technique. The skinfold method requires calipers but provides the most accurate at-home estimate.
For the most accurate results, measure at the same time of day (morning is ideal) and track trends over weeks rather than focusing on single readings. All methods have some margin of error, so consistency matters more than precision.
