Body fat calculations are estimates for general informational purposes only. Actual body fat percentage may differ from these estimates depending on individual body composition, measurement accuracy, and other factors. These results should not be used as a substitute for professional medical assessment. For accurate body composition analysis, consult healthcare professionals who can use clinical methods like DEXA scans. TopCalculatorOnline is not responsible for any health decisions made based on these calculations.How This Body Fat Calculator Works
Our free Body Fat Calculator estimates your body fat percentage using two proven methods: the U.S. Navy circumference method and the 3-site skinfold caliper method. It also calculates your fat mass, lean body mass, and provides a health assessment based on your results.
Body fat percentage is a more accurate indicator of health than weight or BMI alone because it tells you how much of your body is composed of fat versus lean tissue (muscle, bone, organs, water). This makes it especially useful for athletes, bodybuilders, and anyone tracking fitness progress.
Calculation Methods Explained
Navy Method (Circumference)
The U.S. Navy method uses simple tape measurements to estimate body fat:
Men: 86.010 × log10(waist − neck) − 70.041 × log10(height) + 36.76
Women: 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387
Skinfold Method (3-Site)
The Jackson-Pollock 3-site skinfold method uses caliper measurements at three body locations:
- Men: Chest, abdomen, and thigh
- Women: Tricep, suprailiac (above hip bone), and thigh
