About Body Fat Percentage

Body fat percentage is the amount of fat mass in your body compared to your total body weight. It's an important health metric that provides insights into your body composition beyond just weight.

Calculation Methods

This calculator offers three different methods for estimating body fat percentage:

  • Navy Formula: Uses circumference measurements (neck, waist, and for women, hip) along with height to estimate body fat. Developed by the US Navy, it's more accurate than BMI for most individuals.
  • BMI Method: Uses the Body Mass Index as a base, then adjusts for age and gender to estimate body fat percentage. Less accurate but requires minimal measurements.
  • Skinfold Method: Measures fat directly under the skin at various sites using calipers. Can be very accurate when performed correctly with proper equipment.
Body Fat Categories

For men:

  • Essential fat: 2-5%
  • Athletic: 6-13%
  • Fitness: 14-17%
  • Average: 18-24%
  • Overweight: 25-29%
  • Obese: 30%+

For women:

  • Essential fat: 10-13%
  • Athletic: 14-20%
  • Fitness: 21-24%
  • Average: 25-31%
  • Overweight: 32-37%
  • Obese: 38%+
Importance of Body Fat Percentage

Understanding your body fat percentage can help:

  • Assess health risks more accurately than weight alone
  • Track fitness progress (especially when building muscle)
  • Set realistic fitness and weight management goals
  • Understand your body composition better
Important Notes
  • This calculator provides estimates only. For more accurate measurements, consider methods like DEXA scans, underwater weighing, or professional skinfold measurements.
  • Hydration levels, recent exercise, and measurement technique can all affect results.
  • Healthy body fat ranges vary by age, gender, and fitness goals.
  • Always consult with healthcare professionals for medical advice and proper interpretation of body composition measurements.
