Body Fat Calculator
Estimate your body fat percentage using simple body measurements. A practical starting point for tracking body composition, fat loss, and lean mass over time.
Enter your measurements
Uses the U.S. Navy body fat formula as a practical estimate.
Use a tape measure held snug against the skin, but not tight. Small measurement errors can noticeably affect the estimate.
Your results
Best used as a tracking baseline, not as a perfect lab-grade measurement.
How this calculator works
This tool uses the U.S. Navy body fat formula, which estimates body fat percentage from body measurements rather than scales or calipers.
It is not perfect, but it is useful for tracking change over time. Use the same tape measure, same method, and same conditions each time for more consistent results.
Train hard. Dress better.
Once your training and body composition goals are dialled in, your gear should be too.
