Maintanance Calorie Calculator

Your maintenance calories are: calories per day

Maintaining a healthy weight is a crucial aspect of overall well-being. To do so, it’s essential to understand your daily caloric needs. The Maintenance Calorie Calculator is a simple tool designed to help you determine the number of calories your body requires to maintain your current weight. By providing your weight, height, age, and gender, this calculator quickly computes your maintenance calories.

Formula: The Maintenance Calorie Calculator uses the Mifflin-St Jeor equation to estimate your maintenance calories based on your weight, height, age, and gender. The formula for males is 88.362 + (13.397 * weight in kg) + (4.799 * height in cm) – (5.677 * age in years). For females, it is 447.593 + (9.247 * weight in kg) + (3.098 * height in cm) – (4.330 * age in years).

How to Use:

  1. Enter your weight in kilograms in the “Weight” field.
  2. Input your height in centimeters in the “Height” field.
  3. Specify your age in the “Age” field.
  4. Select your gender from the drop-down menu.
  5. Click the “Calculate” button.
  6. Your maintenance calories will be displayed below.

Example: Suppose you are a 30-year-old male with a weight of 75 kg and a height of 180 cm. After entering these details and selecting “Male” as your gender, you click the “Calculate” button. The calculator will reveal that your maintenance calories are approximately 1834.92 calories per day.


  1. What are maintenance calories?
    • Maintenance calories represent the number of calories your body needs to maintain your current weight. Consuming this amount of calories will neither lead to weight gain nor weight loss.
  2. Why is gender a factor in the calculation?
    • Gender matters because men and women tend to have different metabolic rates. The calculator uses distinct formulas for each gender.
  3. Is the Mifflin-St Jeor equation accurate for everyone?
    • While it provides a reasonable estimate for most people, individual variations exist. Factors like muscle mass and activity level can influence your actual maintenance calories.
  4. What if I want to lose or gain weight?
    • To lose weight, you should consume fewer calories than your maintenance calories. To gain weight, consume more. A general rule is that a 500-calorie deficit or surplus per day can result in a 0.45 kg (1 lb) change in weight per week.
  5. Can I use this calculator for weight loss or gain goals?
    • While it’s primarily for maintenance calories, you can use the result as a starting point for your weight management plan.
  6. Should I consult a healthcare professional before making dietary changes?
    • It’s advisable to consult a healthcare provider or a registered dietitian, especially if you have specific health concerns or dietary needs.
  7. How often should I recalculate my maintenance calories?
    • Your maintenance calories may change with weight fluctuations or age, so it’s a good practice to recalculate periodically.
  8. Is this calculator suitable for athletes or bodybuilders?
    • Athletes or bodybuilders with high activity levels may require more calories. Consider consulting a sports nutritionist for a personalized plan.
  9. What’s the difference between maintenance calories and basal metabolic rate (BMR)?
    • Maintenance calories include your daily activities, whereas BMR represents the calories needed at rest. Maintenance calories factor in your activity level.
  10. Can I use this calculator if I have dietary restrictions or specific health conditions?
    • Yes, you can use it as a starting point, but it’s essential to adapt your diet to meet your specific dietary needs and health requirements.

Conclusion: Understanding your maintenance calories is fundamental for managing your weight. The Maintenance Calorie Calculator simplifies this process by providing a quick estimate based on your weight, height, age, and gender. Keep in mind that this tool offers a general guideline, and individual variations may apply. For personalized dietary and weight management advice, consult a healthcare professional or registered dietitian.
