Body fat percentage represents how much of your body’s total weight comes from fat. Everyone has some body fat — it’s essential for energy, hormone production, and insulation. The Body Fat Calculator (sometimes called a body fat level calculator or calculator BMI female for women-specific estimates) helps you estimate your percentage of body fat based on simple body measurements. It’s a practical tool for understanding how lean or fat your body composition really is — far beyond what the scale alone can tell you.
