This tool will help you calculate your daily calorie needs based on your personal information and activity level.
How to Use the Calorie Calculator

How It Calculates the Results
The calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR), which represents the number of calories you would burn per day at rest.
For men: BMR = 10 * weight(kg) + 6.25 * height(cm) – 5 * age(years) + 5
For women: BMR = 10 * weight(kg) + 6.25 * height(cm) – 5 * age(years) – 161
The result is then multiplied by an activity factor to estimate your total daily calorie needs based on your activity level:
- Sedentary: BMR * 1.2
- Lightly active: BMR * 1.375
- Moderately active: BMR * 1.55
- Active: BMR * 1.725
- Very active: BMR * 1.9
Limitations
