Our body fat calculator uses a scientifically validated formula that relies on key body measurements, such as your neck, waist, and hip circumference, along with your height, gender, and weight. It provides a simple estimate of your body fat percentage without the need for expensive equipment.

A healthy body fat percentage varies based on age and gender. For men, a healthy range is generally 10-20%, while for women it is 20-30%. The tool provides a visual chart to help you understand where your results fall.
