Body Fat Percentage Calculator
The Body Fat Percentage Calculator helps you estimate your body fat percentage using various methods, including the Navy method (circumference measurements), BMI method, and skinfold measurements. Body fat percentage is a more accurate indicator of health and fitness than weight or BMI alone, as it distinguishes between fat mass and lean mass.

Frequently Asked Questions
How accurate are these health calculators?
Our health calculators use standard formulas and methodologies recognized in the medical and fitness communities. However, they provide estimates rather than precise measurements. For BMI and calorie calculations, the accuracy depends on the honesty and accuracy of your inputs. Body fat percentage calculations are estimates and can vary from direct measurement methods like DEXA scans. Pregnancy due date calculations are estimates based on average pregnancy duration, but actual delivery dates can vary. For personalized health advice, consult with healthcare professionals.
Can I use these calculators for children or adolescents?
Most of our health calculators are designed for adults. For children and adolescents, different standards and calculations apply. For example, BMI for children and teens is age and gender-specific and is expressed as a percentile. Similarly, calorie needs for growing children differ from adults. If you're calculating health metrics for someone under 18, consult with a pediatrician or healthcare provider for appropriate tools and interpretations.
How often should I recalculate my health metrics?
The frequency of recalculation depends on your goals and circumstances. For weight management, checking your BMI and calorie needs every 2-4 weeks is reasonable as your weight changes. For pregnancy calculations, the due date typically remains the same throughout pregnancy unless adjusted by a healthcare provider. Body fat percentage measurements are often done every 4-8 weeks when tracking fitness progress. Regular recalculation helps you adjust your health and fitness plans based on your changing body and needs.
Should I make health decisions based solely on these calculators?
No, these calculators should be used as informational tools rather than the sole basis for health decisions. They provide useful estimates and starting points, but individual health needs vary based on factors these calculators may not account for, such as medical conditions, medications, genetic factors, and specific health goals. For personalized health advice, dietary plans, fitness programs, or pregnancy care, consult with qualified healthcare professionals like doctors, registered dietitians, certified fitness trainers, or obstetricians.
