How Body Fat Is Calculated

Navy Method

The U.S. Navy body fat calculator uses circumference measurements to estimate body fat percentage. For men, it uses neck and waist measurements. For women, it includes hip measurements.

YMCA Method

The YMCA method uses weight and waist circumference measurements. It’s simpler than the Navy method but generally considered slightly less accurate.

Both methods provide estimates only. For precise measurements, consider professional methods like DEXA scans or hydrostatic weighing.
