What is Body Fat Percentage?

Body fat percentage is the proportion of your body made up of fat. Unlike BMI, which only considers weight and height, body fat percentage provides a better picture of your overall body composition by distinguishing fat from lean mass.

Why Body Fat Percentage Is More Accurate Than BMI

While BMI is a general health indicator, it doesn’t account for muscle mass. For example, athletes may have a high BMI but low body fat. Body fat percentage helps identify whether excess weight comes from fat or muscle.

Recommended Body Fat Ranges

• Men: 6–24% (ideal: 10–20%)
• Women: 14–31% (ideal: 18–28%)

Common Measurement Methods

Body fat can be measured using methods like bioelectrical impedance (BIA scales), calipers, DEXA scans, or circumference-based formulas. This calculator uses the U.S. Navy Method, which estimates body fat based on your neck, waist, hip (for women), and height.

Formula Used

Men:
Body Fat % = 495 / (1.0324 – 0.19077 × log₁₀(waist – neck) + 0.15456 × log₁₀(height)) – 450

Women:
Body Fat % = 495 / (1.29579 – 0.35004 × log₁₀(waist + hip – neck) + 0.22100 × log₁₀(height)) – 450
