This body fat calculator uses the U.S. Navy circumference method to estimate your body fat percentage from measurements like height, neck, waist, and hip. It also categorizes the estimated body fat level.
Use it to track trends over time rather than as an exact measurement. For precise body composition analysis, more advanced methods such as DEXA scans, Bod Pod, or caliper measurements are recommended.
Enter your information in the fields above, run the calculation, and review the result to understand what it means for your situation.
Look at the output in the context of your overall goals rather than in isolation. Consider how sensitive the result is to changes in your inputs (for example, adjusting the amount, rate, or time) to understand which factors matter most.
This tool is a simplified model and does not capture every nuance of real life. Treat it as a planning aid, not a guarantee. For important financial or health decisions, combine these results with professional advice and more detailed analysis.
