Army Body Fat Calculator

The 2026 latest standard, in one ratio

The live result that counts on a record day is not a percent. Army Directive 2026-13 made waist-to-height ratio the only body-composition screen, effective 7 July 2026. Measure height in stocking feet. Measure waist at the navel, typically to the next half inch down. Divide waist by height. Truncate to three decimal places. Do not round. Below 0.550 passes. 0.550 and above fails. Rank, MOS, age, and sex do not move that line.

Worked example: 70 inches tall, 34 inches at the navel. 34 / 70 = 0.485, which truncates to 0.485 and passes. Same Soldier at 38.5 inches: 38.5 / 70 = 0.550 exactly, which fails. The max passing waist at 70 inches is 38.0 inches (0.542). The result panel shows that next bar as soon as you type.

There is no AFT score that exempts you. Army Directive 2025-17's 465-point exemption is gone. If the ratio fails, the Army Body Composition Program path starts, even with a 500 AFT. Use the Army PT Calculator for event points, then come back here for the composition screen that sits beside the test.

What still exists if you enter neck

An army body fat calculator with neck is the old DoD circumference method. Men: waist minus neck, then a log10 formula against height. Women: waist plus hip minus neck. That is the army tape test calculator most NCOs still remember from DA Form 5501. The Army rescinded that tape. This form still asks for neck (and hip for women) so you can compare a unit archive or a private log. The percent is labeled rescinded. It does not pass or fail you.

Male percent = 86.010 × log10(waist − neck) − 70.041 × log10(height) + 36.76. Female percent = 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387. Measurements in inches. If waist is not larger than neck (men), or waist plus hip is not larger than neck (women), the formula is invalid and the page says so instead of inventing a number.

Related search "New Army tape test calculator 2026" is why the 2026 latest standard badge sits at the top. The new test is not a new tape. It is no tape. A page that still leads with neck, hip, and a 20-36% cap is scoring a retired rule.

How this relates to the army height and weight calculator

The army height and weight calculator on this site is the same 0.550 rule, laid out as height versus maximum navel waist. Body fat and height-weight are not two chances anymore. They are one screen. If you fail WHtR, you cannot "tape out." If you pass WHtR, a screening-weight table cannot fail you. Open the height and weight tables when you want every height from 58 to 80 inches in one chart. Stay here when you also want the old neck formula beside the live ratio.

Weight in pounds is optional on the height-weight page and unused here. The Army no longer uses a maximum weight by height to decide body composition. Logging weight is fine for your own trend. It is not a pass line.

Measure the same way your unit will measure: height on a stadiometer or against a wall, no boots. Waist at the navel, not the narrowest point of the torso, tape snug but not compressing skin. Truncation matters. 38.49 / 70 is 0.549 and passes. 38.50 / 70 is 0.550 and fails. Half-inch tape resolution is why the max-waist table steps by 0.5 inch.

If you fail: ABCP is the next administrative bar

2026 has no rank-based body fat cap. A sergeant and a private share 0.550. The next bar after a fail is administrative, not a looser number for a higher grade. Units enroll Soldiers who fail body composition in the Army Body Composition Program. A high AFT does not skip that. Use the next-bar line in the result panel: it tells you how many inches at the navel you must lose to get under 0.550, and it restates the max waist for your height.

Train the waist you measure, not the waist you wish the tape sat on. Diet, sleep, and a run of duty days with a smaller navel measurement move the ratio. Event work on the Army AFT Score Chart still matters for promotion packets. It does not replace this screen.
