This tool helps you calculate the calories you need each day based on your personal information.
How to Use the Calorie Calculator
This calculator helps you estimate your daily calorie needs based on your age, gender, weight, height, and activity level.
- Enter your age in years.
- Select your gender.
- Enter your weight in kilograms.
- Enter your height in centimeters.
- Select your activity level from the dropdown menu.
- Click the “Calculate” button to see your estimated daily calorie needs.
How It Calculates Results
The calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR) and then multiplies it by an activity factor to estimate your daily caloric needs.
- Men: BMR = 88.362 + (13.397 * weight) + (4.799 * height) – (5.677 * age)
- Women: BMR = 447.593 + (9.247 * weight) + (3.098 * height) – (4.330 * age)
The result is then multiplied by your activity level:
- Sedentary (little or no exercise): BMR * 1.2
- Lightly active (light exercise/sports 1-3 days/week): BMR * 1.375
- Moderately active (moderate exercise/sports 3-5 days/week): BMR * 1.55
- Very active (hard exercise/sports 6-7 days a week): BMR * 1.725
- Super active (very hard exercise & a physical job): BMR * 1.9
