What is the US Navy Body Fat Assessment?

The US Navy utilizes a circumference-based method to estimate body fat percentage. This method involves taking measurements of your height, neck, waist (and hips for women). These measurements are then plugged into a specific formula to calculate an estimated body fat percentage. This method is used to ensure service members meet the required physical standards.

Why is Body Fat Percentage Important?

Body fat percentage is a more accurate measure of fitness than BMI alone, as it differentiates between lean mass and fat mass. Tracking this metric can help individuals:

  • Assess overall health risks.
  • Monitor progress in fitness programs.
  • Set realistic and achievable fitness goals.

Calculating Your Body Fat Percentage

The US Navy method uses the following formulas:

  • For Men: % Body Fat = 86.010 * log10(waist - neck) - 70.041 * log10(height) + 36.76
  • For Women: % Body Fat = 163.205 * log10(waist + hip - neck) - 97.684 * log10(height) - 78.387

While the formulas might seem daunting, our percentage calculator can assist you in quickly determining your body fat percentage using these formulas. This saves you time and ensures accuracy, whether you're checking if you meet military standards or monitoring your personal fitness progress.

  • Age 18-21: Males (22%), Females (33%)
  • Age 22-29: Males (23%), Females (34%)
  • Age 30-39: Males (24%), Females (35%)
  • Age 40+: Males (26%), Females (36%)
