Army Body Fat Calculator (Men)

Enter your age, height, neck circumference, and waist circumference into the calculator below to determine your body fat percentage. This calculator uses the formula created for the Army’s body composition program.

Army Body Fat Formula

The following formula is used by the army to calculate an approximate body fat percentages.

%BF = (86.010 * log10( waist – neck ) ) – [70.041 * log10(height)) + 36.76

  • BF% is the body fat percentage
  • waist is your waist circumference (in)
  • neck is your neck circumference (in)
  • height (in)

While this formula is not 100% accurate for all bodies, it is a good approximation to sift through thousands of possible applicants. If you take a look at the formula above, the best way to reduce this body fat percentage is to reduce the waist circumference, which is done through losing weight in general

Losing weight depends on a simple formula of eating less calories then you burn.
