This tool helps you calculate your daily calorie needs based on your personal information.
CSIRO Calorie Calculator
This calculator estimates your daily calorie needs based on your Basal Metabolic Rate (BMR) and your level of physical activity. BMR is the number of calories required to keep your body functioning at rest, while the additional calories needed are based on your activity level.
How to Use the Calculator
- Enter your age in years.
- Select your sex.
- Input your weight in kilograms (kg).
- Input your height in centimeters (cm).
- Select your activity level from the dropdown menu.
Click the Calculate button to see your estimated daily calorie needs in the result box.
How It Calculates
The calculator uses the Mifflin-St Jeor equation to estimate your BMR:
- For males: BMR = 88.362 + (13.397 × weight) + (4.799 × height) – (5.677 × age)
- For females: BMR = 447.593 + (9.247 × weight) + (3.098 × height) – (4.330 × age)
Your daily calorie needs are then calculated by multiplying your BMR by your level of physical activity.
Limitations
Please note that this calculator provides an estimate based on average metabolic rates. Individual results may vary due to factors such as muscle mass, metabolic health, and specific lifestyle habits. Consult with a healthcare provider or nutritionist for personalized advice.
