What is the Army Body Fat Calculator?

An Army body fat calculator applies the US Army tape-measure protocol to estimate body fat percentage and compare it with the service\u2019s standards.

Why use this calculator?

Army regulations keep set maximum body fat values by age and sex. Knowing where you stand helps you prepare for a body composition assessment.

How to use it

  1. Enter your age, gender and height.
  2. Measure waist, neck (and hip for women) at the standard locations.
  3. Read your body fat estimate and the applicable Army maximum.

Formula

Perimeter formulas with logarithms, same structure as the Navy method.
Official results come from certified personnel using the prescribed order of measurement. This estimate is for planning only.
Frequently Asked Questions
Where do I measure the waist?
The Army protocol measures at the navel for men and at the point of smallest circumference for women. Follow current doctrine precisely for official tests.
What if I am over the standard?
Bodies respond to a sensible calorie deficit and strength training. Check the current regulation, and consider a DEXA scan for an accurate baseline.
Is this a medical diagnosis?
No. This tool provides general wellness information only. It is not a substitute for evaluation by a qualified healthcare professional.
Why do results differ from my doctor's measurements?
Clinical measurements use calibrated equipment and professional technique. Home estimates rely on formulas and self-reported values, so small differences are normal.
How often should I recalculate?
Recheck after meaningful changes such as weight gain or loss, a new workout routine, or every few months to track trends over time.
Do these formulas apply to everyone?
Most population formulas are less accurate for athletes, pregnant people, very young children and the elderly. Use them as a general guide.
Is this calculator free to use?
Yes. Every calculator on this site is completely free, with no hidden fees, no subscriptions and no limits on how many times you can use it.
How accurate are the results?
We use standard, widely accepted formulas and calculate in your browser using double-precision arithmetic. Results are rounded for readability, so treat them as reliable estimates rather than a guarantee. Real-world factors can vary the true figure.
Can I add this calculator to my own website?
Yes. Open this calculator page and use the "Add to your website" box in the sidebar to copy a ready-made iframe snippet, then paste it into any HTML page.
Does it work on a phone or tablet?
Yes. The layout is fully responsive, so it works on desktops, laptops, tablets and mobile phones, and every input adapts to touch screens.
