What is a body fat calculator?

A body fat calculator estimates your body fat percentage using body measurements like height, neck, waist, and hip. It gives more detail than BMI because it focuses on fat percentage instead of just weight.

What is body fat percentage?

Body fat percentage is the amount of fat in your body compared to your total body weight. It helps you understand body composition better than weight alone.

How is body fat calculated here?

This calculator uses the U.S. Navy Method, which estimates body fat using circumference measurements. It is a common formula for quick body fat estimates.

Why is body fat different from BMI?

BMI only compares height and weight. Body fat percentage gives a better idea of how much of your body is fat, which makes it more useful for many people.

Healthy body fat ranges

For men, a healthy range is often around 10% to 20%.
For women, a healthy range is often around 18% to 28%.
This can vary by age, fitness level, and body type.
