How Body Fat is Calculated
The FinCalcPro Body Fat Calculator uses the U.S. Navy Method, a widely recognized formula developed at the Naval Health Research Center. This method uses body circumference measurements and height to estimate body density and fat percentage.
While the Gold Standard for body fat measurement is DXA scanning or hydrostatic weighing, the Navy Method provides a highly accessible and surprisingly accurate alternative for most people—usually within a 3-4% margin of error.
The Importance of Lean Mass
Tracking body fat is often more useful than tracking total weight alone. Knowing your Lean Body Mass allows you to ensure that your weight loss is coming from fat reserves rather than muscle tissue, which is vital for metabolic health and physical performance.
Pro Tip: Accuracy Matters
For the most accurate results, measure in the morning before eating. Use a soft tape measure and ensure it is taut against the skin but not compressing the tissue.
