Mayo Clinic Maintenance Calorie Calculator

Your daily maintenance calories:

Maintaining a healthy lifestyle requires an understanding of your body’s energy needs. The Mayo Clinic Maintenance Calorie Calculator is a useful tool for determining the number of calories you need to maintain your current weight based on various factors such as age, weight, height, gender, and activity level.

Formula: The Mayo Clinic Maintenance Calorie Calculator uses the Harris-Benedict equation to estimate your Basal Metabolic Rate (BMR). The BMR is then multiplied by an activity factor to calculate your daily maintenance calories. The formulas used in the calculator are as follows:

  • For males: BMR = 88.362 + (13.397 * weight in pounds) + (4.799 * height in inches) – (5.677 * age in years).
  • For females: BMR = 447.593 + (9.247 * weight in pounds) + (3.098 * height in inches) – (4.330 * age in years).

The activity factor is selected based on your activity level:

  • Sedentary: BMR * 1.2
  • Lightly active: BMR * 1.375
  • Moderately active: BMR * 1.55
  • Very active: BMR * 1.725

How to Use:

  1. Enter your weight in pounds.
  2. Enter your height in inches.
  3. Enter your age in years.
  4. Select your gender.
  5. Choose your activity level.
  6. Click the “Calculate” button to find out your daily maintenance calories.

Example: Suppose you are a 30-year-old male, weighing 180 pounds, with a height of 70 inches, and you engage in moderate exercise (activity level: Moderately active). After using the calculator, you find out that your daily maintenance calories are approximately 2,663.41 calories per day.


Q1: What is the Basal Metabolic Rate (BMR)? A1: The Basal Metabolic Rate (BMR) is the number of calories your body needs to maintain basic functions at rest, such as breathing and digestion.

Q2: Why is gender considered in the calculation? A2: Gender plays a role in the calculation because men and women tend to have different body compositions and metabolic rates.

Q3: What is the significance of activity level in the calculation? A3: Activity level reflects how active your lifestyle is and influences the number of calories you burn through physical activity.

Q4: Is this calculator suitable for weight loss or gain goals? A4: No, this calculator determines maintenance calories. To lose or gain weight, you need to adjust your calorie intake accordingly.

Q5: Can I use this calculator if I use the metric system (kg and cm)? A5: The calculator is currently designed for the imperial system (pounds and inches). You can convert your measurements if necessary.

Conclusion: The Mayo Clinic Maintenance Calorie Calculator is a valuable tool for individuals looking to maintain their current weight by understanding their daily calorie requirements. By considering factors such as weight, height, age, gender, and activity level, you can make informed choices about your dietary and exercise habits to support a healthy lifestyle. It’s important to remember that this calculator provides an estimate, and individual results may vary. If you have specific dietary or fitness goals, it’s recommended to consult a healthcare professional or nutritionist for personalized advice.
