What is Body Fat Percentage?
Body fat percentage is the proportion of your body weight that consists of fat tissue. Unlike BMI, it provides a more accurate assessment of body composition by distinguishing between fat mass and lean mass (muscle, bone, organs). Our calculator uses three proven methods: the US Navy Method (most accurate, using body measurements), Jackson-Pollock formula, and Deurenberg formula to give you precise body fat calculations with personalized health insights.

Frequently Asked Questions
What body fat percentage ranges are considered healthy?
For men: Essential fat (2-6%), Athletic (6-18%), Average (18-25%), Obese (>25%). For women: Essential fat (10-12%), Athletic (12-25%), Average (25-32%), Obese (>32%). Athletes typically have lower percentages.
Which calculation method is most accurate?
The Navy Method is generally most accurate as it uses actual body measurements (waist, neck, hip). Jackson-Pollock and Deurenberg methods are also reliable but use height, weight, age, and gender for estimation.
How do I measure my body for the Navy Method?
Measure waist at the narrowest point, neck just below the Adam's apple, and hip at the widest point (women only). Use a flexible measuring tape and measure in the morning for consistency.
Can I use both metric and imperial units?
Yes, you can switch between metric (cm) and imperial (inches) units. The calculator automatically converts and recalculates your body fat percentage.
Why is body fat percentage better than BMI?
Body fat percentage distinguishes between fat mass and lean mass (muscle, bone), providing a more accurate health assessment. BMI can misclassify muscular individuals as overweight.
How often should I measure my body fat?
For fitness tracking, measure monthly. For general health monitoring, every 3-6 months is sufficient. Always measure at the same time of day for consistency.
What health insights does the calculator provide?
The calculator provides personalized recommendations based on your body fat percentage, age, and gender, including health risk assessments and fitness level categorization.
