What is Body Fat Percentage?

Body fat percentage is the total mass of fat divided by total body mass, multiplied by 100. It includes essential body fat (necessary for normal physiological functioning) and storage body fat (accumulated in adipose tissue).

Unlike BMI, body fat percentage directly measures body composition, making it a more accurate indicator of health and fitness levels.

Deurenberg Formula (Used in This Calculator) Body Fat % = (1.20 × BMI) + (0.23 × Age) − (10.8 × Gender) − 5.4
Gender: 1 for Male, 0 for Female | BMI = Weight (kg) / Height (m)²

How to Measure Waist Circumference

Accurate waist measurement is crucial for body fat estimation. Follow these steps:

  1. Stand Up Straight: Stand with feet shoulder-width apart
  2. Find Your Waist: Locate the narrowest point between ribs and hips
  3. Wrap the Tape: Place measuring tape around your waist, parallel to the floor
  4. Breathe Normally: Don't suck in your stomach—breathe normally
  5. Read the Measurement: Check the measurement at the end of a normal exhale
