Formula Used

Our calculator uses the following formula to estimate body fat percentage for women:

Body Fat Percentage = (1.20 × BMI) + (0.23 × Age) - 5.4

Where:

BMI = Weight (kg) / (Height (m) × Height (m))
Age is in years

This formula provides a reasonable estimate based on common health metrics. Keep in mind that this is an approximation and actual body fat measurements may vary.

Interpreting Your Results

Understanding what your body fat percentage means can help you make informed decisions about your health. Here's a general guide:

Body Fat Percentage	Classification	Health Considerations
Below 14%	Severely underweight	Potential nutritional deficiencies, osteoporosis risk
14-20%	Underweight	May need to gain muscle mass
21-33%	Healthy	Optimal balance of muscle and fat
34-39%	Overweight	Increased risk of health issues
40% and above	Obese	Significant health risks

Worked Example

Let's walk through an example calculation to see how the formula works in practice.

Suppose we have a 30-year-old woman who is 165 cm tall and weighs 60 kg. Here's how we calculate her body fat percentage:

First, calculate the BMI:
BMI = 60 kg / (1.65 m × 1.65 m) = 60 / 2.7225 ≈ 22.04
Now apply the body fat percentage formula:
Body Fat Percentage = (1.20 × 22.04) + (0.23 × 30) - 5.4 = 26.448 + 6.9 - 5.4 = 28.048%

Based on this calculation, our example woman would have approximately 28.05% body fat. According to the general guidelines, this falls into the "Healthy" range.
