This tool helps you calculate your daily calorie needs based on your personal information.
How to Use This Calculator

How It Calculates the Results
This daily calorie intake calculator uses the Mifflin-St Jeor Equation to calculate your Basal Metabolic Rate (BMR), which is the number of calories your body needs to perform basic life-sustaining functions. The formula is different for men and women:
- For men: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years)
- For women: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years)
The calculator then multiplies your BMR by an activity factor based on your selected 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
- Active (hard exercise/sports 6-7 days a week): BMR * 1.725
- Very active (very hard exercise/sports & physical job): BMR * 1.9
