Body Composition Calculator

Tracking your fitness progress isn’t just about weight loss. It’s about understanding what your weight is made of—fat, muscle, water, and bone. Our Body Composition Calculator gives you a complete view of your health by measuring key data like BMI, body fat percentage, muscle mass, body water, and more.

🧠 Why Body Composition Is More Important Than Weight Alone

A standard weighing scale only tells you how much you weigh—but not how much of that is fat, muscle, or water. That’s where a body composition calculator makes all the difference.

It’s especially helpful if you are:

  • Trying to lose body fat

  • Working to build muscle

  • Aiming to boost athletic performance

  • Monitoring your overall health and fitness

🛠️ How to Use the Body Composition Calculator

Using the calculator is simple. Just enter the following details:

  • Gender (Male/Female)

  • Age

  • Weight in kilograms

  • Height in centimeters

Click “Calculate”, and you’ll instantly see a full breakdown of your body composition.
