Body Fat Calculator


This body fat calculator is a tool that estimates the amount of body fat someone has based on various measurements, such as height, weight, and body circumference.

The calculator works by using a formula that takes into account these measurements to determine the person’s body fat percentage.

Body fat percentage is an important indicator of overall health, as excess body fat can increase the risk of various health problems, such as heart disease, diabetes, and certain types of cancer.

It’s important to maintain a healthy body fat percentage to help reduce the risk of these health issues.

This formula takes into account gender-specific differences in body composition, as well as age and height, which can affect body fat distribution.

For men:

Body Fat Percentage = 495 / (1.0324 – 0.19077 × log10(waist – neck) + 0.15456 × log10(height)) – 450

For women:

Body Fat Percentage = 495 / (1.29579 – 0.35004 × log10(waist + hip – neck) + 0.22100 × log10(height)) – 450

Your calculation will be between these following numbers:

  • Recommended amount: For Women – 20-25% For Men – 8-14%
  • Adults in United States, average: For Women – 22-25% For Men – 15-19%
  • Obese: Women – 30%+ Men – 25%+

They can provide a helpful tool for individuals looking to monitor their body fat levels and improve their overall health. However, it’s important to keep in mind that these calculators are only estimates and may not be as accurate as more advanced measurement methods.


It’s important to note that this formula provides an estimate of body fat percentage and may not be as accurate as more advanced measurement methods. Additionally, factors such as physical activity level, diet, and genetics can also affect body composition.
