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.

Important note

This calculator gives an estimate, not a medical diagnosis. Results may vary depending on body shape and measurement accuracy.

Learn More About BMI and Body Fat

BMI is one of the most common ways to check if your weight is in a healthy range. It is simple and quick, but it does not tell the full story about your body.

BMI only looks at your height and weight. It does not consider muscle, fat, or body composition. This means two people can have the same BMI but completely different body types.

For a more accurate understanding of your health, it is important to compare BMI with body fat percentage.
