Body Fat Percentage Calculator
Estimate your body fat percentage using scientifically validated measurement methods.
Body fat percentage is a more accurate indicator of health and fitness than weight alone. It shows the proportion of your body weight that consists of fat versus lean mass (muscle, bone, organs, and water). Understanding your body composition helps you set realistic fitness goals and track progress effectively.
Our calculator uses proven methods including the Navy Body Fat formula and US Army formula, which use simple body measurements to estimate body fat percentage. These methods are widely used by fitness professionals and military organizations for their accuracy and practicality.

Understanding Body Fat Percentage
Learn how to interpret your body fat percentage and use it to improve your health and fitness
Healthy Ranges
Men: 10-20% (athletes 6-13%), Women: 16-24% (athletes 14-20%). These ranges support optimal health and performance.
Measurement Methods
Navy Method uses waist, neck, and height. US Army formula includes hip measurements for women. Both are accurate and practical.
Health Benefits
Maintaining healthy body fat levels reduces disease risk, improves energy levels, and enhances physical performance and appearance.
Tracking Progress
Monitor changes monthly rather than daily. Body fat percentage changes more slowly than weight but provides better insight into fitness progress.
Accuracy Tips
Measure at the same time of day, ensure consistent posture, and use the same measurement technique for reliable results.
Remember: Body fat percentage is just one metric of health. Focus on overall fitness, strength, and how you feel rather than achieving a specific number.
These calculations provide estimates. For the most accurate body composition analysis, consider DEXA scans, hydrostatic weighing, or other professional methods.
