Your Estimated Body Fat Percentage:

How Body Fat Is Calculated

Modern body fat calculators use formulas such as BMI-based estimates or Bioelectrical Impedance Analysis (BIA), combined with age, gender, and physical data to estimate body fat percentage.

Common BMI-based formulas (for reference):

Men: Body Fat % = (1.20 × BMI) + (0.23 × Age) − 16.2

Women: Body Fat % = (1.20 × BMI) + (0.23 × Age) − 5.4

This provides a quick estimate of your body fat level to guide health and fitness decisions.
