Army Body Fat Calculator
Estimate your body fat percentage and see how it compares to Army standards for your age and sex.
How this is calculated
This uses the same circumference-based formula as the standard body fat calculator (neck, waist, and for women, hip), then compares the result against commonly cited U.S. Army body composition standards, which set a maximum allowable body fat percentage by age group and sex. This is an estimate for general reference, not an official readiness assessment.
