Frequently Asked Questions
What is a healthy body fat percentage?
For men: Essential 2-5%, Athletes 6-13%, Fitness 14-17%, Average 18-24%, Obese 25%+. For women: Essential 10-13%, Athletes 14-20%, Fitness 21-24%, Average 25-31%, Obese 32%+. These ranges vary by age and fitness goals.
How accurate is the Navy method?
The Navy tape measure method provides a reasonable estimate (typically within 3-5% of DEXA scans) when measurements are taken correctly. It's more accurate than BMI for athletes and those with higher muscle mass.
Is this calculator free to use?
Yes, ApexSofteck Tools's Body Fat Calculator is completely free. Use it unlimited times to track your body composition without any registration.
How do I measure correctly?
Measure in the morning after using the bathroom. Neck: narrowest point. Waist: at navel level. Hip: widest part of buttocks. Use a flexible tape measure and keep it snug but not compressing the skin.
Should I focus on body fat or weight?
Body fat percentage is more meaningful than scale weight. Two people can weigh the same but have very different body compositions. Focus on reducing body fat while preserving or building lean muscle mass for optimal health.
