Body Fat Percentage Calculator
Use the U.S. Navy Method to accurately estimate your body fat percentage based on key body measurements.
The U.S. Navy Body Fat Calculation Method
The **Body Fat Percentage Calculator** uses anthropometric measurement—specifically the **U.S. Navy Method** (or USN BFP)—which is a simple, non-invasive way to estimate body fat. It correlates measurements from the waist, neck, and height with laboratory methods.
Why is Body Fat Percentage Important?
Unlike BMI, which only considers weight and height, BFP gives a better indication of overall health and fitness by directly estimating the proportion of fat mass in the body. Healthy ranges vary significantly by age and sex.
