Army Body Fat Calculator
Estimate body fat percentage using the measurement inputs required by the Army-style method. Results are estimates and should not replace an official assessment. It can be useful for understanding a general estimate, but the result should be viewed in context rather than as a diagnosis or treatment decision.
How to use this calculator
Enter the measurements requested by the tool and use the same measurement method throughout. Small differences in waist, neck, or other inputs can noticeably change an estimate.
Formula
The U.S. Army body-fat method uses height plus sex-specific neck, waist, and sometimes hip measurements according to the selected standard.
Before you use the result
This result is an estimate based on the inputs and the method used by the calculator. Different formulas or measurement methods can produce different values, and the result should not be treated as a diagnosis or a substitute for advice from a qualified health professional.
