Free Online BMI (Body Mass Index) Calculator Tool

What Is BMI and Why Is It Important?

Body Mass Index (BMI) is a simple numerical value derived from your weight and height. It is widely used by health professionals to determine whether an individual maintains a healthy body weight for their height. Although it is not a perfect measurement of health, BMI remains one of the most popular and effective screening tools for identifying potential weight-related health risks.

How the BMI Calculator Works

The formula is straightforward:

BMI = Weight (kg) / Height (m)²

Once your BMI is calculated, it falls into one of four main categories:

• Underweight — BMI below 18.5
• Healthy Weight — BMI 18.5 to 24.9
• Overweight — BMI 25 to 29.9
• Obese — BMI 30 or above

Why Use a BMI Calculator?

BMI helps individuals quickly understand whether they may be at risk of health issues such as cardiovascular disease, diabetes, and hypertension. While BMI is not a full diagnostic tool, it offers a good first step for evaluating general wellness.
