This tool calculates the calories you need each day based on your personal details and activity level.
How it Works
This calculator estimates your daily calorie needs based on your age, gender, weight, height, and activity level. It uses the Mifflin-St Jeor Equation to calculate Basal Metabolic Rate (BMR) then multiplies the BMR by an activity factor to estimate total calorie needs.
How to Use
1. Enter your age in years.
2. Select your gender.
3. Enter your weight in kilograms.
4. Enter your height in centimeters.
5. Select your activity level. Sedentary means little or no exercise, lightly active means light exercise 1-3 days/week, moderately active means moderate exercise 3-5 days/week, very active means hard exercise 6-7 days a week, and super active means very hard exercise and a physical job.
6. Click “Calculate” to see your daily calorie needs.
