Understanding Body Fat Percentage

Body fat percentage is the proportion of fat your body contains compared to everything else—organs, muscles, bones, and water. Unlike BMI, which only considers height and weight, body fat percentage gives a more accurate picture of your fitness level.

The U.S. Navy Method used in this calculator is one of the most reliable non-invasive ways to estimate body fat.

Athletes 6-13% 14-20%
Fitness 14-17% 21-24%

Obese 25%+ 32%+
