About Body Fat Percentage Calculator


Body Fat Percentage Calculator gives two common estimates of body fat. The BMI method is fast and uses only age, height, and weight, while the US Navy method adds circumference measurements for a more individualized estimate. The result also compares the current percentage with an age-based ideal level.

How To Use It


BMI is the quickest option. Switch to US Navy when you want the estimate to reflect neck, waist, and hip measurements.

  • Choose measurement system, gender, age, and the calculation method.
  • Enter height and weight, then add neck, waist, and hip measurements if you use US Navy.
  • Click Calculate Body Fat to review percentage, category, lean mass, and the ideal comparison.
