About Body Fat Calculator

Our free body fat calculator uses the U.S. Navy Body Fat Formula to estimate your body fat percentage based on circumference measurements. This method provides a practical alternative to expensive body composition testing and is widely used by military and fitness professionals.

Body fat percentage is a more accurate indicator of health and fitness than BMI alone, as it distinguishes between muscle mass and fat mass, providing better insights for fitness goals and health assessment.

  2. Choose Units: Select imperial (inches) or metric (centimeters)
  3. Measure Height: Enter your height in the selected unit
  4. Measure Neck: Measure neck circumference at the narrowest point
  5. Measure Waist: Measure waist at the narrowest point (males) or at navel level (females)
  6. Measure Hips (Females Only): Measure hips at the widest point
  7. Calculate: Click "Calculate Body Fat" to get your estimated percentage
