Army Body Fat Calculator (2023 one-site method)
Estimate your Army Body Composition Program (ABCP) body-fat percentage with the current 2023 one-site method. Army Directive 2023-11 replaced the old two-site tape test — neck and waist, plus hip for women — with a single abdominal circumference measured at the navel, combined with your body weight and sex, and it became the sole authorized ABCP method in 2024. Many third-party "army body fat calculator" pages still show the deprecated two-site formula; this tool uses the current one-site standard. For a woman weighing 150 lb with a 32-inch abdomen the estimate is about 29.2%: −9.15 − 0.015 × 150 + 1.27 × 32. Alongside the percentage you get your fat-mass and lean-mass split in kilograms plus an FFMI reading, scored against the roughly 25 natural drug-free ceiling. Remember this is an estimate — circumference methods run about ±3–4% versus a DEXA scan, so use DEXA or calipers for a precise figure. General fitness guidance, not a compliance ruling.
Current Army 2023 one-site: %BF = a + b·weight(lb) + c·abdomen(in) — one abdominal measurement
- Female, 150 lb, abdomen 32″ → ≈ 29.2% body fat
- The old neck+waist two-site test is deprecated (superseded by Directive 2023-11)
Frequently asked questions
What is the new Army body fat test for 2023?
Army Directive 2023-11 replaced the two-site tape test (neck and waist, plus hip for women) with a single one-site abdominal circumference measured at the navel, combined with weight and sex. It became the sole authorized ABCP method in 2024. This tool uses that current one-site standard, not the deprecated two-site formula many pages still show.
Is the old neck and waist Army body fat test still used?
No. The neck-and-waist two-site tape test (plus hip for women) was deprecated by Directive 2023-11 and is no longer the authorized ABCP method. The Army now uses the one-site abdominal measurement. If a calculator asks for your neck measurement for an "army" result, it is showing the outdated method.
