Body Fat Calculator 2026 – Calculate Body Fat Percentage from Measurements
The body fat calculator estimates body fat percentage based on waist, hip, and neck circumference along with height and weight using the US Navy method. The result shows which body fat category you're in.
Enter measurements in inches or centimeters, and the calculator computes estimated body fat percentage and compares it to health-recommended reference values. Body fat percentage is a more accurate health indicator than BMI since it distinguishes muscle mass from fat tissue.
What is a healthy body fat percentage?
For men, healthy body fat percentage is 10–20%, for women 18–28%. Athletes typically have lower body fat: men 6–13%, women 14–20%. Over 25% (men) or over 32% (women) indicates obesity, which carries health risks.
