How the Body Fat Calculator Works
This calculator uses the U.S. Navy method, a body circumference formula developed to estimate body fat percentage. It relies on a few simple body measurements and is a convenient way to get a general idea of your body composition without expensive equipment.
For men, the formula is: Body Fat % = 495 / (1.0324 - 0.19077 * log10(waist - neck) + 0.15456 * log10(height)) - 450
For women, the formula is: Body Fat % = 495 / (1.29579 - 0.35004 * log10(waist + hip - neck) + 0.22100 * log10(height)) - 450
The measurements should be taken in centimeters for the calculation, but our tool handles the conversion from inches automatically if you select imperial units.
