Army Body Fat Calculator (ABCP)
Calculate your body fat percentage using the official U.S. Army Body Composition Program tape test method per AR 600-9. See if you meet Army standards and compare with general fitness ranges.
The Army Body Composition Program (ABCP) uses circumference-based measurement per AR 600-9. Soldiers who exceed screening weight are taped at the neck, waist, and (for women) hips. The formula is based on DoD Instruction 1308.3 and differs from the Navy method used in our standard Body Fat Calculator.

How the Army Tape Test Works
The Army Body Composition Program (ABCP) under AR 600-9 uses a two-step process. First, soldiers are screened against height-weight tables. Those who exceed the screening weight are then measured using the circumference-based tape test. For men, the neck and waist are measured. For women, the neck, waist, and hips are measured. All measurements are taken to the nearest half inch and rounded down. The measurements are entered into the DoD body fat formula (based on the Hodgdon-Beckett equations), which uses logarithmic calculations to estimate body fat percentage.
This calculator uses the exact same formula specified in DoD Instruction 1308.3. It is mathematically identical to what your unit uses for ABCP assessments. However, measurement technique matters — inconsistent taping can cause results to vary by 2-3 percentage points.
Measurement Protocol
Neck: Measure just below the larynx (Adam's apple) perpendicular to the long axis of the neck. The tape should not contact the chin. Round down to the nearest half inch.
Waist (Men): Measure at the navel level, at the end of a normal exhalation. Keep the tape horizontal. Round up to the nearest half inch.
Waist (Women): Measure at the narrowest point of the natural waist (usually between the bottom of the ribs and the top of the hip bones). Round up to the nearest half inch.
Hips (Women only): Measure at the widest point of the buttocks as viewed from the side. Round up to the nearest half inch.
Army vs Navy Method
Both the Army and Navy use circumference-based body fat formulas derived from the Hodgdon-Beckett equations (1984). The formulas are mathematically identical — the difference is in the measurement protocol and the standards applied. Our standard Body Fat Calculator uses the Navy protocol. This page uses the Army protocol with Army-specific maximum body fat standards. For a complete body composition picture, also check your BMI, waist-to-hip ratio, and lean body mass.
Improving Your Score
To reduce body fat percentage for ABCP compliance, focus on two variables: reducing waist circumference and maintaining or increasing neck circumference (which reflects lean mass). A calorie deficit of 500 calories below your TDEE produces approximately 1 lb/week of fat loss. Use the Calorie Deficit Calculator for a personalized plan. Prioritize protein intake at 1.6-2.0g/kg to preserve lean mass during the deficit, and maintain heavy compound lifts tracked with the One Rep Max Calculator.
Running and rucking are primary Army fitness activities — optimize your training with the Pace Calculator and Target Heart Rate Calculator. Track calorie burn with the Calories Burned Calculator. Ensure adequate sleep (7-9 hours) and hydration — dehydration can temporarily affect tape measurements.
