Body Fat Calculator
Get a professional analysis of your body composition in seconds. Our tool uses science-backed formulas to help you track your fitness journey effectively.
How it Works
This tool uses the U.S. Navy Method, one of the most reliable ways to estimate body fat without expensive scans. It compares your height and waist measurements to determine how much of your weight is fat versus muscle and bone.
Why it Matters
Knowing your body fat percentage helps you understand your health risks better than BMI. High body fat can increase risks for heart health, while maintaining a healthy “Lean Mass” supports your metabolism and strength.
How to Measure Accurately
For the best results, measure in the morning before eating. Use a flexible measuring tape and keep it snug against the skin without pulling too tight. Consistency is key to tracking your progress over time.
