Body Fat Calculator – Understand Your Body Composition

What is Body Fat?

Body fat is the percentage of fat tissue in your body compared to total body weight. Maintaining a healthy body fat percentage is essential for overall health, fitness, and wellness. Excess body fat can increase the risk of heart disease, diabetes, and other health conditions, while too little body fat may affect hormonal balance and physical performance.

Why Calculate Body Fat?

Knowing your body fat percentage gives a clearer picture of your fitness level than weight or BMI alone. Unlike BMI, which only considers weight and height, body fat measurement accounts for muscle mass, fat distribution, and body composition. Regular tracking helps you monitor progress during exercise, dieting, or lifestyle changes.

How to Measure Body Fat

Our Body Fat Calculator uses the U.S. Navy Method and BMI Method to provide an accurate estimate based on gender, age, weight, height, neck, and waist measurements. You can choose between Metric (kg/cm) and US Units (lb/in) for convenience.
