Daily Calorie Needs Calculator

Daily Calorie Needs Calculator

Understanding how many calories your body needs each day can help you make informed decisions about your diet, energy levels and long-term health. This calculator uses your age, sex, height, weight and activity level to estimate your Basal Metabolic Rate (BMR) and the number of calories you may need to maintain your current weight.

Your BMR is the amount of energy your body needs at rest to function, while your daily calorie needs include your normal activity levels. This can be useful if you’re thinking about changes to your lifestyle, weight, or fitness.

Using this tool can give you a clearer picture of your daily calorie requirements. Remember that these figures are estimates and individual needs can vary, especially for people with medical conditions, those who are pregnant, or those with higher muscle mass.

How to use the calculator

  1. Enter your age.

2. Select your sex.

3. Enter your height in centimetres.

4. Enter your weight in kilograms.

5. Select your typical daily activity level.

6. Click “Calculate daily calories” to see your estimated BMR and daily calorie needs.

Use this information as a general guide. For personalised advice or concerns about your weight or nutrition, please speak to a GP, nurse or dietitian.
