A body fat calculator helps you understand your health. It measures fat percentage in your body. This is crucial for fitness goals. Moreover, it reveals health risks better than weight alone.
Knowing your body composition matters. It guides nutrition and exercise plans. Additionally, tracking changes motivates progress. Therefore, regular measurement is valuable.
Our calculator uses proven methods. It provides accurate estimates easily. Simply input your measurements. Then get instant results.
Body fat calculators estimate your fat percentage. They use mathematical formulas. These formulas consider body measurements. For instance, waist, hip, and neck circumferences.
Some methods include skinfold measurements. Others use bioelectrical impedance. Our calculator uses circumference method. It’s simple and non-invasive.
Different formulas exist for men and women. Gender affects fat distribution patterns. Age also impacts results. Our tool accounts for these factors.
For Men:
% Body Fat = 495 / (1.0324 - 0.19077 * log10(waist - neck) + 0.15456 * log10(height)) - 450
For Women:
% Body Fat = 495 / (1.29579 - 0.35004 * log10(waist + hip - neck) + 0.22100 * log10(height)) - 450

A: This calculator provides a good estimate using the U.S. Navy method. For clinical accuracy, professional methods like DEXA scans are better. However, it's excellent for tracking changes over time.
A: Measure every 4-8 weeks. Daily measurements aren't useful due to natural fluctuations. Consistent timing (morning before eating) gives most reliable comparisons.
A: BMI only considers height and weight. Body fat percentage measures actual fat content. Athletes often have high BMI but low body fat. Body fat percentage is a superior health indicator.
A: No, pregnancy changes body composition significantly. Standard formulas don't apply. Consult your healthcare provider for appropriate guidance during pregnancy.
A: Women naturally carry more essential body fat for reproductive functions. Healthy ranges differ by gender. Men typically have 3-5% essential fat, women 10-13%.
