Body Fat Calculator
Determine your Body Fat Percentage (BFP) using scientifically accepted methods like the U.S. Navy formula.
Understanding Your Body Composition
Learn the distinction between fat types, healthy ranges, and the formulas used for estimation.
Essential vs. Storage Fat
Essential fat is necessary for survival (2-5% for men; 10-13% for women). Storage fat accumulates in adipose tissue (subcutaneous and visceral) and is the target of fitness goals.
Healthy Range
The healthy body fat range is typically 8-19% for men and 21-33% for women, though this varies based on age, lifestyle (athlete vs. average), and specific guidelines.
Navy & BMI Formulas
- U.S. Navy Method:Uses circumference measurements (waist, neck, hip) and height to estimate BFP. Provides good field accuracy.
Health Risks
Excess body fat (obesity) is a leading preventable cause of death, increasing risks for heart disease, stroke, certain cancers, and Type 2 diabetes. Insufficient fat also leads to health issues.
