Body Fat Calculator – Calculate Your Body Fat Percentage

Body fat percentage is the amount of fat in your body compared to other tissues like muscles, bones, and organs.
The Body Fat Calculator by ToolsGen helps you estimate your body fat percentage using various methods including the US Navy method.

Knowing your body fat percentage is a better indicator of health than BMI alone, as it distinguishes between fat mass and lean mass.

How is Body Fat Calculated?

The US Navy method uses measurements to estimate body fat:

For Men:


BF% = 495 / (1.0324 - 0.19077 × log10(waist-neck) + 0.15456 × log10(height)) - 450

For Women:


BF% = 495 / (1.29579 - 0.35004 × log10(waist+hip-neck) + 0.22100 × log10(height)) - 450
