Formula

The formula used in this calculator is the Body Fat Percentage Formula by Deurenberg, which is considered accurate and reliable:

$B o d y F a t P erce n t a g e = (1.2 \times BM I) + (0.23 \times A g e) - 5.4 - (10.8 \times G e n d er)$

Where:

BMI (Body Mass Index) is calculated as $BM I = He i g h t ^{2} W e i g h t$
Age is the age of the person in years.
Gender is 1 for males and 0 for females.

Example

Let’s consider an example: a 30-year-old female with a BMI of 22.5.

$B o d y F a t P erce n t a g e = (1.2 \times 22.5) + (0.23 \times 30) - 5.4 - (10.8 \times 0)$

$B o d y F a tP erce n t a g e \approx 24.55%$
