How does the Army body fat calculator work?

The Army uses a two-step process. First you are screened against the AR 600-9 height/weight table. If you exceed screening weight, body fat is estimated with the official one-site circumference tape method using abdominal circumference at the navel and body weight. Results are compared to maximum allowable body fat standards by age and gender.

What is the Army body fat formula?

For males: % body fat = -26.97 − (0.12 × weight in pounds) + (1.99 × abdomen circumference in inches). For females: % body fat = -9.15 − (0.015 × weight in pounds) + (1.27 × abdomen circumference in inches). Round the result to the nearest whole percent.

What are the Army maximum body fat standards?

Ages 17–20: 20% male / 30% female. Ages 21–27: 22% male / 32% female. Ages 28–39: 24% male / 34% female. Age 40 and over: 26% male / 36% female. These are the maximum allowable percent body fat standards under the Army Body Composition Program.

How do I measure abdominal circumference for the Army tape test?

Stand upright with arms at your sides. Measure abdominal circumference at the level of the belly button (navel). Take three measurements, average them, and round to the nearest 0.5 inch. Weight should be rounded to the nearest pound.

Army Body Fat Calculator

Check AR 600-9 height/weight screening and calculate body fat with the official Army one-site tape test. Instant pass/fail against current maximum body fat standards.

The Army body fat calculator uses the one-site abdominal circumference method (abdomen + weight). Max standards: 20–26% for men and 30–36% for women, depending on age.

Based on Army Body Fat Assessment guidance (AD 2023-11 / ABCP) and AR 600-9 screening tables. For informational use only — not an official Army form.

How to Use This Army Body Fat Calculator

Enter age, gender, height, weight, and abdominal circumference at the navel. This army body fat calculator checks AR 600-9 height/weight screening first, then estimates body fat with the official one-site tape formulas and compares you with maximum allowable standards by age group.

If you only want a quick screening check, leave abdomen blank after entering height and weight. If you already know you need the tape test, fill abdomen (and optional traditional neck/hip fields) to see pass/fail against the ABCP max body fat table.

How the Army Body Fat Assessment Works

The U.S. Army Body Composition Program (ABCP) uses a two-step process. First, soldiers are screened against the AR 600-9 height/weight table. If you are at or below the screening weight for your height, age, and gender, no tape test is required. If you exceed screening weight, body fat is estimated with a circumference-based tape method and compared to maximum allowable standards.

Step 1: Height/weight screening (Table B-1)

Table B-1 lists maximum screening weights by height (inches), age group, and gender. Commanders use it to expedite semi-annual checks. This army body fat calculator looks up your screening weight automatically and shows pounds over/under the max. Soldiers below the table minimum weight are typically referred for medical evaluation.

Height is measured in stocking feet and rounded to the nearest inch (0.5″ and above rounds up). Weight is rounded to the nearest pound. Measurements are taken in a standard PT uniform.

Step 2: One-site tape test (current method)

Since June 2023 (Army Directive 2023-11), the Army uses a one-site abdominal circumference method for both men and women. Take three measurements at the belly button, average them, and round to the nearest 0.5 inch:

Male formula:

%BF = −26.97 − (0.12 × weight lb) + (1.99 × abdomen in)

Female formula:

%BF = −9.15 − (0.015 × weight lb) + (1.27 × abdomen in)

Example (male)

Abdomen 35 in, weight 210 lb → −26.97 − 25.2 + 69.65 = 17.48% → rounds to 17% body fat.

Example (female)

Abdomen 30 in, weight 165 lb → −9.15 − 2.475 + 38.1 = 26.475% → rounds to 26% body fat.

Army Maximum Body Fat Standards

Maximum allowable percent body fat by age group (AR 600-9 / ABCP). Your calculated body fat must be at or below the max for your age and gender:

Age group	Male max	Female max
17–20	20%	30%
21–27	22%	32%
28–39	24%	34%
40 and over	26%	36%

Exceeding screening weight is not an automatic fail. Many soldiers are over the height/weight table but still meet the body fat standard on the tape test — that is a pass for composition purposes.

Sample Screening Weights (AR 600-9 Table B-1)

These are example maximum screening weights at common heights. The calculator uses the full table from 58″–80″:

Height	Male 21–27	Male 28–39	Female 21–27	Female 28–39
66 in (5′6″)	163 lb	168 lb	156 lb	158 lb
68 in (5′8″)	174 lb	179 lb	166 lb	168 lb
70 in (5′10″)	185 lb	189 lb	176 lb	178 lb
72 in (6′0″)	195 lb	200 lb	186 lb	188 lb
74 in (6′2″)	206 lb	211 lb	197 lb	199 lb
76 in (6′4″)	217 lb	223 lb	207 lb	210 lb

How to Take Army Tape Measurements

Wear PT gear — shorts and T-shirt; no shoes for height/weight.
Height — stocking feet, chin parallel to floor; round to nearest inch.
Weight — round to nearest pound.
Abdomen — stand upright, arms at sides, tape horizontal at the navel. Do not suck in. Average three measurements; round to nearest 0.5 inch.
Consistency — same time of day and landmark reduces noise between checks.
Enter values above — the calculator runs screening + the tape formula for you.

Traditional DoD Method vs One-Site Method

Before 2023, the Army used a multi-site DoD circumference method: neck + abdomen for males; neck + waist + hips for females. That approach is similar to the U.S. Navy body fat calculator. After a transition period, the one-site abdominal method became the authorized circumference tape for Army body composition assessment.

This tool defaults to the current one-site formulas and optionally shows the traditional DoD estimate for comparison. For official unit actions, follow current Army publications — not a third-party calculator.

ACFT / AFT Exemption

Soldiers who score high enough on the Army Combat Fitness Test (or the successor Army Fitness Test), with minimum scores in each event, may be exempt from the body fat assessment even if they exceed screening weight. Exact score thresholds have changed in Army guidance over time (for example, earlier ACFT guidance used a 540 total with 80+ per event). Confirm the current exemption with your unit’s policy before relying on it.

If You Fail the Tape Test

Soldiers who fail circumference testing may be flagged and enrolled in the Army Body Composition Program (ABCP). When reasonably available, a supplemental assessment may include:

Dual-energy X-ray absorptiometry (DXA)
InBody 770 body composition analyzer
Bod Pod body composition system

If supplemental testing is not requested or is also failed, commanders typically maintain the flag and continue ABCP enrollment, counseling, and follow-up weighing/taping per regulation.

How to Lower Body Fat for Army Standards

If you are over the max, focus on sustainable fat loss while protecting strength and ACFT/AFT performance:

Moderate calorie deficit — usually 300–500 kcal below maintenance, not crash dieting
High protein — helps preserve lean mass while cutting
Strength + conditioning — keep lifting and training events that matter for your test
Sleep and stress — poor recovery makes fat loss and tape results worse
Re-measure consistently — same landmark, same time of day, every 1–2 weeks

Use our calorie deficit calculator, protein intake calculator, and Navy body fat calculator for broader body-composition tracking outside Army standards.

How this calculator works

We look up your AR 600-9 screening weight, then apply the official male/female one-site equations (or optional traditional DoD formulas). Results show body fat %, maximum allowed for your age/gender, pass/fail status, and pounds over/under screening weight.

Frequently asked questions

How accurate is the Army tape test?+

The one-site method was adopted to improve consistency versus the older multi-site tape. It is still an estimate — DXA and other lab methods are more precise. Take three measurements at the same landmark and time of day for the most reliable result.

Do I need neck and hip measurements?+

Not for the current official Army one-site assessment — only abdomen at the navel and weight. Neck and hips apply to the traditional DoD method, which this calculator can show optionally for comparison or for use with our general body fat calculator.

What if I am under the minimum weight?+

Soldiers below the minimum weight on Table B-1 are typically referred for medical evaluation. This calculator flags that condition when your weight is below the table minimum for your height.

Is this the same as a civilian body fat calculator?+

No. Civilian tools often use Navy, Jackson-Pollock, or BIA estimates with different cutoffs. The Army body fat calculator is built specifically for ABCP screening weights and Army max body fat standards by age and gender.

What are the Army body fat standards by age?+

Ages 17–20: 20% male / 30% female. Ages 21–27: 22% / 32%. Ages 28–39: 24% / 34%. Age 40+: 26% / 36%. These are maximum allowable percentages under the Army Body Composition Program.

What happens if I fail the Army tape test?+

You may be flagged and enrolled in the ABCP. When available, you may request a supplemental assessment such as DXA, InBody 770, or Bod Pod. Follow your unit’s counseling and current regulation for timelines and requirements.

Who is exempt from the body fat assessment?+

High scorers on the ACFT/AFT with minimum event scores may be exempt even if over screening weight. Thresholds change — verify current Army guidance with your unit before assuming exemption.

How do I measure abdomen for the Army tape test?+

Stand upright with arms at your sides. Place the tape at the level of the belly button. Take three measurements, average them, and round to the nearest 0.5 inch. Do not suck in or pull the tape so tight that it compresses the skin.
