Army Body Fat Percentage Calculator
Instantly check if you meet Army body composition standards using the official 2023 single-site circumference tape test.
Measure horizontally around your belly button while standing relaxed.
| Age Group | Maximum Body Fat % |
|---|---|
| 17 – 20 | 20% |
| 21 – 27 | 22% |
| 28 – 39 | 24% |
| 40 and over | 26% |
-
1Wear minimal clothing
Remove shoes and heavy outer clothing before being weighed.
-
2Stand relaxed and erect
Do not suck in or push out your abdomen — stay in a natural, relaxed stance.
-
3Measure at the belly button
Wrap the tape horizontally around your abdomen at the level of your navel. The tape should be snug but not compressing the skin.
-
4Take three measurements and average them
Official Army testing requires three consecutive measurements averaged together for accuracy.
-
5Round to the nearest 0.5 inch
Official measurements are recorded to the nearest half-inch before plugging into the formula.
In June 2023, the Army released Army Directive 2023-11, replacing the older multi-site tape method with a new single-site circumference-based test developed by the U.S. Army Research Institute of Environmental Medicine (USARIEM). Only one measurement — the abdominal circumference at the belly button — is needed alongside body weight.
Female: Body Fat % = −9.15 − (0.015 × weightlbs) + (1.27 × abdomenin)
Results are rounded to the nearest whole percent. A Soldier who fails the primary tape test may use the older multi-site method as a confirmation tape test for 12 months from the directive date. After that period, the single-site method is the only authorized circumference-based test.
What is the maximum body fat percentage allowed in the Army?
Limits depend on age and sex. Males: 20% (17–20), 22% (21–27), 24% (28–39), 26% (40+). Females: 30% (17–20), 32% (21–27), 34% (28–39), 36% (40+). These are set by Army Regulation 600-9, the Army Body Composition Program.
When did the Army update its body fat calculator?
The Army introduced its new single-site circumference-based tape test in June 2023 under Army Directive 2023-11. The previous method required measurements at multiple body sites (neck, waist, hips for females). The new formula requires only an abdominal circumference at the belly button plus body weight.
What happens if I fail the Army body fat tape test?
Soldiers who fail the primary single-site tape test may use the older multi-site confirmation tape test for 12 months from Army Directive 2023-11. If both tests are failed, the Soldier may request a supplemental body fat assessment (DXA, InBody 770, or Bod Pod®) if reasonably available. Failure of all assessments results in referral to the Army Body Composition Program (ABCP), previously called the Army Weight Control Program (AWCP).
Does the Army use BMI or body fat percentage?
The Army relies on body fat percentage estimated via the circumference-based tape test — not BMI. A Soldier who exceeds height/weight screening tables may still pass if their body fat percentage is within the allowed range for their age and sex, since high BMI can be due to muscle mass.
How accurate is the Army tape test body fat estimate?
The tape test is an estimate — not a clinical measurement. It can be affected by measurement technique and individual body proportions. The 2023 formula was developed by USARIEM to improve accuracy over the previous method. For the highest precision, clinical tools like DXA (DEXA scan) or air-displacement plethysmography (Bod Pod) are more accurate, and the Army allows these as supplemental assessments.
What is the Army Body Composition Program (ABCP)?
The Army Body Composition Program (formerly the Army Weight Control Program) provides structured support — including nutrition counseling, fitness guidance, and medical evaluation — for Soldiers who do not meet Army body composition standards. Soldiers referred to ABCP are given a reasonable period to meet standards before adverse administrative actions are taken.
Can I use this calculator for ACFT or APFT purposes?
Body composition is assessed separately from the Army Combat Fitness Test (ACFT). The ACFT evaluates physical performance across six events. However, meeting body composition standards (AR 600-9) is a separate readiness requirement — Soldiers must pass both the ACFT and the body composition assessment to be considered fully fit for duty.
