What is Body Fat Percentage?

Body fat percentage refers to the proportion of fat in your body compared to your total body weight. Unlike weight alone, it helps distinguish between fat mass and lean mass (muscles, bones, water, etc.).

For example, two people may weigh the same, but one may have more muscle while the other has more fat. That’s why body fat percentage is a much better indicator of fitness.

Example Calculation

Let’s understand how the calculator works with a real example:

Input:

Gender: Male
Age: 30
Height: 175 cm
Weight: 75 kg

Step 1: Calculate BMI
BMI = Weight / (Height in meters)²
= 75 / (1.75 × 1.75)
= 24.49

Step 2: Calculate Body Fat % (Male Formula)
= (1.20 × BMI) + (0.23 × Age) − 16.2
= (1.20 × 24.49) + (0.23 × 30) − 16.2
= 29.38 + 6.9 − 16.2
= 20.08%

Step 3: Ideal Range
For males: 10% – 20%

Result:

BMI: 24.49
Body Fat: 20.08%
Ideal Range: 10% – 20%

This means the person is right at the upper edge of the healthy range.

2. Helps Set Fitness Goals

Whether you want to lose fat or gain muscle, this metric helps guide your journey.

3. Monitors Health Risks

High body fat levels are linked to health issues such as heart disease and diabetes.
