What is Body Fat Percentage?
Body fat percentage represents the proportion of your total body weight that consists of fat tissue. Unlike BMI, which only considers height and weight, body fat percentage provides a more accurate picture of your body composition and health status.
Why Body Fat Percentage Matters More Than Weight
Accurate Health Assessment
Two people with the same weight can have vastly different body compositions. Muscle weighs more than fat, so body fat percentage gives a clearer health picture.
Fitness Progress Tracking
Track real progress as you build muscle and lose fat. The scale might not move, but your body fat percentage will show improvements.
Better Than BMI
Athletes often have "overweight" BMIs due to muscle mass, but healthy body fat percentages reveal their true fitness level.

How to Calculate Body Fat Percentage: 3 Proven Methods
Our body fat percentage calculator uses three scientifically validated methods to give you accurate results:
🔵 Navy Method (Most Accurate)
Accuracy: ±3-4%
Measurements needed: Neck, waist, and hip (women only)
Developed by the U.S. Navy, this method uses body circumference measurements and is considered the gold standard for body fat calculation without expensive equipment.
Men: Uses neck and waist measurements
Women: Uses neck, waist, and hip measurements
Women: Uses neck, waist, and hip measurements
🟡 YMCA Method (Simple)
Accuracy: ±5-6%
Measurements needed: Waist circumference only
A simpler method that requires only waist measurement along with basic demographics. Less accurate than Navy method but easier to perform.
🟠 BMI Method (Basic Estimation)
Accuracy: ±7-8%
Measurements needed: Height and weight only
Uses BMI calculation with age and gender adjustments. Least accurate but requires no body measurements.
