This tool helps you calculate the number of calories you need each day based on your personal information.
How It Works
This calculator estimates your daily calorie needs based on your age, gender, weight, height, and level of physical activity. Here’s a breakdown of the parameters:
- Age: Your age in years.
- Gender: Specify whether you are male or female as it affects the calculation.
- Weight: Your weight in kilograms.
- Height: Your height in centimeters.
- Activity Level: Your daily activity level from sedentary to super active.
How to Use It
Enter your personal information into the form fields and click the “Calculate” button to see your estimated Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
Calculation Details
The Basal Metabolic Rate (BMR) is calculated using either the Mifflin-St Jeor Equation for males or females:
- Males: BMR = 10 * weight + 6.25 * height – 5 * age + 5
- Females: BMR = 10 * weight + 6.25 * height – 5 * age – 161
The Total Daily Energy Expenditure (TDEE) is then calculated by multiplying the BMR by an activity factor:
- 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/sports & physical job or 2x training): BMR * 1.9
Limitations
While this calculator provides a good estimate of daily calorie needs, it has its limitations:
- Doesn’t account for muscle mass or body composition.
- Individual metabolic rates can vary.
- Results are estimates and can vary based on numerous factors.
