About Body Fat Percentage
Body fat percentage is one of the most important indicators of overall health, fitness, and metabolic function. Unlike BMI—which only considers height and weight—body fat percentage measures how much of your body is made up of stored fat versus lean mass. Maintaining a healthy body fat level supports hormone balance, mobility, energy levels, and long-term well-being.
Body Fat Categories:
| Category | Men (%) | Women (%) |
|---|---|---|
| Essential Fat | 2–5 | 10–13 |
| Athletes | 6–13 | 14–20 |
| Fitness | 14–17 | 21–24 |
| Average | 18–24 | 25–31 |
| Obese | ≥25 | ≥32 |
Use your results as a reference point rather than a strict diagnosis. Everyone’s body stores fat differently due to genetics, age, lifestyle, and body type. Aim for steady improvement and balance instead of perfection. This calculator is ideal for tracking progress over time.
