How accurate are body fat calculators?

Body fat calculators using measurements provide estimates with a margin of error of 3-5%. They are less accurate than DEXA scans or hydrostatic weighing but more accurate than BMI alone. Consistency in measuring technique is crucial. Use these calculators to track trends over time rather than focusing on absolute accuracy.

What is a healthy body fat percentage?

Healthy body fat percentages vary by gender and age. For men: essential fat is 2-5%, athletes 6-13%, fitness 14-17%, average 18-24%, and obese 25%+. For women: essential fat is 10-13%, athletes 14-20%, fitness 21-24%, average 25-31%, and obese 32%+. These ranges help assess health risks and fitness levels.

What methods does this calculator use?

This calculator supports multiple methods including Navy Method (using neck, waist, hip, and height measurements), US Army Method, and BMI-based estimation. The Navy Method is generally considered the most accurate of the measurement-based formulas. Each method has strengths and limitations.
