Introduction to the Body Fat Calculator

The Body Fat Calculator is an essential tool to estimate your body fat percentage based on weight, height, age, and other inputs. Knowing your body fat percentage is vital for understanding your overall fitness level and assessing potential health risks. This calculator goes beyond BMI by offering more specific insights into your body composition.

Why Use a Body Fat Calculator?

Here are some reasons to use a Body Fat Calculator:

Health Insights: It helps track body fat levels to ensure you remain in a healthy range.

Custom Fitness Goals: Aids in designing tailored workout and diet plans.

Weight Management: Helps monitor changes in body composition during fitness or weight-loss programs.

Formulas Used in the Body Fat Calculator

The Body Fat Calculator employs two common methods:

U.S. Navy Method:

This method uses measurements of the waist, neck, and hip (for females) in addition to height:

Formula:

For males: Body Fat % = 86.010 × log10(Waist - Neck) − 70.041 × log10(Height) + 36.76

For females: Body Fat % = 163.205 × log10(Waist + Hip - Neck) − 97.684 × log10(Height) − 78.387

Example:

A male with a waist circumference of 85 cm, neck of 40 cm, and height of 180 cm:
Body Fat % = 86.010 × log10(85 - 40) − 70.041 × log10(180) + 36.76 = 17.2%

BMI Method:

This method derives body fat percentage from BMI:

Formula:

For males: Body Fat % = (1.20 × BMI) + (0.23 × Age) − 16.2

For females: Body Fat % = (1.20 × BMI) + (0.23 × Age) − 5.4

Example:

A female with a BMI of 22 and age of 30:
Body Fat % = (1.20 × 22) + (0.23 × 30) − 5.4 = 23.1%

How to Calculate Body Fat Percentage

Body fat can be calculated using formulas based on inputs like weight, height, age, and gender. Here is an example formula:

Formula: Body Fat % = (1.20 × BMI) + (0.23 × Age) − (10.8 × Gender) − 5.4

Note: For Gender, use 1 for males and 0 for females.

Example: A 25-year-old male with a BMI of 23.96:
Body Fat % = (1.20 × 23.96) + (0.23 × 25) − (10.8 × 1) − 5.4 = 16.3%
