The Body Fat Percentage Calculator uses the U.S. Navy Method, one of the most accurate ways to estimate your body fat level. Unlike BMI, which only considers height and weight, this calculator uses specific measurements of your body—neck, waist, height, and hips (for females)—to calculate body fat percentage more precisely.
Body fat percentage is a key indicator of your overall fitness and health, helping you understand whether your body composition is ideal, needs improvement, or is at risk.
Knowing your body fat percentage helps you set realistic fitness and health goals. It gives you better insight than BMI alone, distinguishing between fat and muscle mass. This calculator is especially useful if you're training, dieting, or simply aiming for a healthier lifestyle.
Monitoring body fat helps you track your progress accurately, allowing targeted adjustments in diet and exercise routines.
Your calculated percentage classifies you into typical health and fitness categories:
Use this classification to assess your health risks and fitness goals effectively. When you enter your weight, the calculator also provides your lean body mass and estimated fat mass.
Your Basal Metabolic Rate (BMR) is the number of calories your body needs at rest. By including your age and typical activity level, this calculator now estimates daily maintenance calories alongside body fat percentage.
These figures help you decide how many calories to eat if you want to maintain, lose, or gain weight. You can copy the result and share it with a coach or keep it for your fitness journal.
The Navy Method provides a reliable estimate for most individuals, using circumference measurements easily obtained at home. Although less precise than professional measurements like hydrostatic weighing or DEXA scans, it still gives a clear indication of your body composition without expensive equipment.
Ensure accuracy by measuring carefully: waist at the narrowest point near your navel, neck just below the Adam's apple, and hips at the widest point.
This calculator is ideal for fitness enthusiasts, athletes, individuals tracking weight loss, and anyone interested in a detailed understanding of their body composition. Fitness trainers, nutritionists, and wellness coaches also recommend this tool to clients for setting realistic and achievable health targets.
