BMI Healthy Weight Calculator
This tool is widely used by health professionals, fitness trainers, and individuals to assess overall health status in a simple and effective way.
What Is BMI (Body Mass Index)?
BMI (Body Mass Index) is a numerical value derived from a person’s weight and height. It is used to classify individuals into different weight categories such as underweight, normal weight, overweight, or obese.
Although BMI does not directly measure body fat, it is a useful screening tool for understanding general health risks.
Why BMI Matters
Understanding your BMI is important for several reasons:
1. Health Awareness
BMI helps you understand if your weight is healthy for your height.
2. Disease Risk Assessment
Higher or lower BMI values can indicate risks of diseases such as:
- Heart disease
- Diabetes
- High blood pressure
3. Fitness Tracking
It helps monitor progress during weight loss or fitness programs.
4. Lifestyle Planning
BMI results can guide diet and exercise decisions.

BMI Formula Explained
The BMI calculation is based on a simple mathematical formula:
BMI Formula
BMI=Height(m)2Weight(kg)
Where:
- Weight is in kilograms
- Height is in meters
Since height is usually entered in centimeters, it is converted into meters:
Height(m)=100Height(cm)
BMI Categories
Based on WHO standards, BMI is divided into four main categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obesity |
These categories help interpret your BMI result and understand potential health risks.
Healthy Weight Range Formula
The calculator also shows your ideal weight range based on BMI 18.5 to 24.9.
Minimum Healthy Weight
Minimum Weight=18.5×Height(m)2
Maximum Healthy Weight
Maximum Weight=24.9×Height(m)2
This range helps you understand what your ideal weight should be for your height.
Example BMI Calculation
Let’s understand with a real example.
Given:
- Weight = 70 kg
- Height = 170 cm
Step 1: Convert Height to Meters
170 cm ÷ 100 = 1.7 m
Step 2: Apply BMI Formula
BMI = 70 ÷ (1.7 × 1.7)
BMI = 70 ÷ 2.89
BMI = 24.22
Step 3: Determine Category
BMI = 24.22 → Normal weight
Step 4: Healthy Weight Range
- Minimum = 18.5 × 2.89 = 53.5 kg
- Maximum = 24.9 × 2.89 = 71.9 kg
Final Result:
- BMI: 24.22
- Category: Normal weight
- Healthy Range: 53.5 kg – 71.9 kg
