How It Works

This calculator uses the U.S. Navy body fat formula, which estimates body fat percentage from circumference measurements:

Men: BF% = 495 / (1.0324 - 0.19077 x log10(waist - neck) + 0.15456 x log10(height)) - 450

Women: BF% = 495 / (1.29579 - 0.35004 x log10(waist + hip - neck) + 0.22100 x log10(height)) - 450

• Measure your neck at the narrowest point, just below the larynx.
• Measure your waist at the navel level (men) or narrowest point (women).
• Women should also measure hips at the widest point.
• Take measurements on bare skin, not over clothing.
