How It Works +

This calculator uses the U.S. Navy method to estimate body fat percentage based on circumference measurements.

Formula for men: %Fat = 495 / (1.0324 – 0.19077 * log10(waist – neck) + 0.15456 * log10(height)) – 450

Formula for women: %Fat = 495 / (1.29579 – 0.35004 * log10(waist + hip – neck) + 0.22100 * log10(height)) – 450

All measurements should be in centimeters. The formulas use logarithmic calculations to provide accurate estimates of body fat percentage.
