Maintaining a healthy body weight requires understanding two important factors: your BMI (Body Mass Index) and your daily calorie needs. These two values work together to help you understand your health status and guide your diet plan.

The BMI Calorie Calculator is a powerful tool that combines BMI calculation with daily calorie estimation. It helps you determine whether your weight is underweight, normal, overweight, or obese—and also tells you how many calories you should eat each day to reach your goal.

This makes it one of the most useful tools for weight management and fitness planning.

What Is BMI?

BMI (Body Mass Index) is a number that shows whether your body weight is healthy for your height.

BMI Categories

How Calorie Needs Are Calculated

After BMI, the calculator estimates your daily calorie needs using TDEE.

Step 1: BMR Calculation

$BMR = 10W + 6.25H - 5A + S$BMR=10W+6.25H−5A+S

---

Step 2: Total Daily Calories

$TDEE = BMR \times Activity\ Factor$TDEE=BMR×Activity Factor
