Formula for Fitness Success

To meet Department of Defense fitness standards, male service members should aim for 18% body fat or lower. Women in the military need to be at 26% body fat or less. By using this tool to determine your current percentage, you can set goals and tailor your training to reach the DoD targets. Getting an accurate read of your body composition is the first step toward meeting military body fat regulations and achieving peak conditioning.

How Calculator works?

It uses your age, gender, height, neck circumference, waist circumference, and hip circumference to estimate your body fat percentage. First, it calculates your body density using circumference measurements and validated mathematical formulas. Body density is then converted to body fat percentage using the Siri equation. This multi-step process draws on anthropometric research to provide an accurate, non-invasive assessment of body composition. With just a tape measure and the Army Calculator, you can determine your body fat percentage anytime and track your fitness progression.
