This tool will estimate your daily calorie needs based on your age, height, gender, and activity level.
How to Use the Calorie Calculator
To use the calorie calculator, fill in your age, gender, height, weight, and activity level, then click the Calculate button. The results will display your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).
Explanation of the Calculations
The BMR is calculated using different formulas for males and females. For males, the formula is:
BMR = 88.362 + (13.397 × weight) + (4.799 × height) – (5.677 × age)
For females, the formula is:
BMR = 447.593 + (9.247 × weight) + (3.098 × height) – (4.330 × age)
The TDEE is then calculated by multiplying the BMR by an activity factor that corresponds to your selected activity level:
- Sedentary: BMR × 1.2
- Lightly active: BMR × 1.375
- Moderately active: BMR × 1.55
- Very active: BMR × 1.725
- Extra active: BMR × 1.9
Limitations
This calculator provides an estimate and is not a precise measurement of your caloric needs. Individual variations such as muscle mass, metabolic rate, and other factors can affect your actual caloric requirements.
