About the Body Fat Percentage Calculator

Our Body Fat Percentage Calculator uses the U.S. Navy method to estimate your body fat percentage based on waist, hip, neck, and height measurements. Tracking body fat is more useful than just checking weight, because it shows your actual fitness level.

Healthy ranges differ by gender: Men usually aim for 10–20% body fat, while women aim for 18–28%. Athletes often fall on the lower end. Knowing your body fat helps in setting realistic fitness and diet goals.

Frequently Asked Questions

What is a healthy body fat percentage?

For men, 10–20% is healthy. For women, 18–28% is considered normal.

Is body fat more important than BMI?

Yes, because BMI only uses weight and height, while body fat tells you how much of your weight is actually fat vs. muscle.

Can this calculator be used for athletes?

Yes. Athletes often have higher muscle mass, so tracking body fat percentage is more accurate than BMI.
