Calculate LBM, BMI & Body Fat %
Lean Body Mass indicates muscle and organ weight
Body Mass Index measures weight relative to height
Percentage of body weight that is fat tissue
Using the Body Composition Analyzer is quick, simple, and requires only basic details about your body. Follow these easy steps to get accurate insights into your Lean Body Mass (LBM), Body Mass Index (BMI), and Body Fat Percentage:
Type your body weight into the input field.
You can choose the unit — kilograms (kg) or pounds (lbs) — from the dropdown menu.
💡 Tip: Make sure you enter an accurate and recent weight for better results.
Add your height in centimeters (cm).
If your height is in feet or inches, convert it before entering.
💡 Example: 5’7″ = 170 cm.
Choose Male or Female from the list.
This helps the calculator apply the correct formula for Lean Body Mass estimation, as gender affects muscle and fat distribution.
Press the green calculate button to start the analysis.
In just a second, the tool will display your:
Lean Body Mass (LBM)
Body Mass Index (BMI)
Body Fat Percentage (BF%)
You’ll also see visual progress bars and colored indicators showing whether you’re in a healthy range.
Check each section:
LBM tells how much of your body is muscle, bones, and organs.
BMI classifies your weight category (Underweight, Normal, Overweight, or Obese).
Body Fat % shows how much of your weight is fat tissue.
💡 These values help you understand whether your fitness routine or diet is working effectively.
The tool automatically saves your last seven analyses in local storage.
You can revisit the “History” section anytime to monitor your progress over time.
Click the Clear button if you want to delete your history.
Your data is completely private — stored only in your browser, never uploaded or shared online.
You can safely use it anytime, anywhere, even offline.
Use this tool every 2–4 weeks to track body changes instead of focusing only on the scale. Consistent monitoring helps you see whether your workouts and diet plans are helping you gain lean mass or reduce fat.
Most people think tracking weight alone is enough to measure health — but that’s far from true. Weight doesn’t tell you how much of your body is made up of muscle, fat, or bone. Two people can weigh the same but have very different body compositions — one may be lean and muscular, while the other may carry excess fat.
This is where body composition analysis becomes crucial. It gives a complete picture of your physical health, helping you understand your Lean Body Mass (LBM), Body Mass Index (BMI), and Body Fat Percentage.
Poor body composition (high fat percentage, low lean mass) can lead to serious health risks like obesity, cardiovascular diseases, hormonal imbalances, and even reduced immunity. By knowing your exact body composition, you can take the right steps — whether it’s improving diet, optimizing workouts, or maintaining a healthy lifestyle.
The Body Composition Analyzer is a free, easy-to-use tool designed to give you accurate insights into your physical health. It calculates three key parameters:
This tool uses scientifically validated formulas to give accurate results and even stores your last seven analyses for tracking progress.
The biggest mistake people make when trying to get fit is relying only on body weight. Your weight can fluctuate daily due to water retention, food intake, or hormonal changes — but that doesn’t mean you’re gaining or losing fat.
By using the Body Composition Analyzer, you can:
Identify whether your fitness progress is due to muscle gain or fat loss.
Understand how your training and nutrition affect your lean mass and fat levels.
Get personalized health feedback based on BMI classification (underweight, normal, overweight, obese).
Avoid the frustration of scale-based tracking and instead monitor real health indicators.
For example, someone who starts resistance training may gain weight due to muscle growth — but their fat percentage will drop. This tool highlights that improvement clearly, preventing demotivation and helping users stay consistent with their fitness goals.
