Calculate Your Calorie Intake

Your estimated daily calorie intake is: calories per day.


Understanding your daily calorie intake is essential for maintaining a healthy and balanced diet. Whether you want to maintain your current weight, lose weight, or gain weight, knowing the right number of calories to consume is a fundamental step. This calculator will help you estimate your daily calorie intake based on your individual factors.


The formula for estimating daily calorie intake combines the Basal Metabolic Rate (BMR) and an activity factor:

  1. BMR Calculation:
    • For Males: BMR = 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years).
    • For Females: BMR = 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years).
  2. Activity Factor: Depending on your activity level, an activity factor is applied to your BMR to estimate your daily calorie intake. The activity levels include sedentary, lightly active, moderately active, very active, and super active, each with a corresponding factor.

How to Use

Using the calculator is a straightforward process. Follow these steps:

  1. Enter your current weight in kilograms.
  2. Input your height in centimeters.
  3. Specify your age in years.
  4. Select your gender (Male or Female).
  5. Choose your activity level from the drop-down list.

Once you’ve completed these steps, click the “Calculate” button. The calculator will then display your estimated daily calorie intake.


For example, consider a 30-year-old male who weighs 75 kilograms, is 175 centimeters tall, and has a moderately active lifestyle:

  • Weight: 75 kg
  • Height: 175 cm
  • Age: 30 years
  • Gender: Male
  • Activity Level: Moderately Active

By entering these values and clicking “Calculate,” the calculator will estimate his daily calorie intake.


  1. What is Basal Metabolic Rate (BMR)?
    • BMR represents the number of calories your body requires to maintain basic functions at rest.
  2. Why does activity level affect calorie needs?
    • Activity level influences the number of calories your body burns through physical activity.
  3. What’s the significance of knowing your daily calorie intake?
    • It helps in maintaining a healthy weight and planning a balanced diet.
  4. How can I adjust my calorie intake for weight loss or gain?
    • To lose weight, create a calorie deficit by consuming fewer calories. To gain weight, create a calorie surplus.
  5. Is this calculator accurate for everyone?
    • It provides a rough estimate, and individual factors may vary.
  6. How often should I recalculate my calorie intake?
    • It’s a good practice to recalculate when your weight, age, or activity level changes significantly.
  7. Is exercise necessary for weight management?
    • While exercise can aid weight management, diet plays a crucial role in achieving your goals.
  8. Can I use this calculator for weight gain goals?
    • Yes, you can adjust your calorie intake based on your desired goals.


Estimating your daily calorie intake is a valuable step in maintaining a healthy and balanced diet. This calculator simplifies the process, providing a rough estimate of your calorie needs based on your individual factors. Remember that this is a rough estimate, and it’s important to combine it with a balanced diet and a healthy lifestyle to achieve your health and fitness goals. If you have specific dietary or health concerns, it’s advisable to consult with a healthcare professional or registered dietitian for personalized guidance.
