Definition: This calculator estimates body fat percentage for adult males based on BMI and age using a validated formula.
Purpose: It helps men assess their body composition and health risks associated with body fat levels.
The calculator uses the formula:

Explanation: This formula accounts for the natural increase in body fat with age and the relationship between BMI and body composition.
Details: Body fat percentage is a better health indicator than weight alone. Healthy ranges are typically 8-19% for young men and 11-22% for older men.
Tips: Enter your BMI (calculate it first if needed) and your current age. The calculator works best for men aged 18-100 with BMI between 18.5 and 35.
Q1: How accurate is this calculator?
A: It provides a reasonable estimate (±3-5%) for most men but may be less accurate for athletes or very muscular individuals.
Q2: What's a healthy body fat percentage?
A: For men: 8-19% (ages 20-39), 11-22% (ages 40-59), and 13-25% (60+).
Q3: How do I calculate my BMI?
A: BMI = weight(kg) / height(m)² or use our BMI calculator tool.
Q4: Why does age affect body fat percentage?
A: Metabolism slows with age, and body composition naturally shifts toward more fat and less muscle.
Q5: Should I use this if I'm very muscular?
A: This method may overestimate fat for bodybuilders. Consider skinfold measurements instead.
