How Many Calories Do I Need Daily? Use Our Free Calorie Calculator

Are you wondering, “How many calories should I consume each day?” You’re not alone. Whether your goal is to lose weight, gain muscle, or simply maintain a healthy lifestyle, understanding your daily calorie needs is the first step. Below, you’ll find our Calorie Calculator powered by the Mifflin-St Jeor formula—one of the most accurate ways to estimate your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE).

What Is BMR (Basal Metabolic Rate)?

Your Basal Metabolic Rate (BMR) is the number of calories your body burns while at complete rest. In other words, it’s the energy your body needs to perform essential functions like breathing, cell repair, and blood circulation. Knowing your BMR helps you understand the minimum caloric requirement your body needs just to stay alive and functioning.

What Is TDEE (Total Daily Energy Expenditure)?

TDEE goes beyond your BMR. It accounts for your daily activities—from working at a desk to intense gym workouts. TDEE is calculated by multiplying your BMR by an activity factor (e.g., sedentary, lightly active, moderately active, etc.). This gives you a more accurate picture of how many calories you need per day to maintain your current weight. If you eat fewer calories than your TDEE, you’re likely to lose weight; eat more than your TDEE, and you’ll gain weight.

Why the Mifflin-St Jeor Formula?

The Mifflin-St Jeor formula is widely recognized by dietitians, nutritionists, and fitness experts as one of the most accurate methods to estimate daily calorie needs. It factors in your gender, age, weight, and height—making it more precise than older formulas like Harris-Benedict.

  • Lifestyle Adjustments: Remember, factors like stress, sleep, and overall health also play a major role in weight management.

Additional Tips for a Healthy Lifestyle

  • Focus on Balanced Nutrition: Fill your plate with lean protein, whole grains, healthy fats, fruits, and vegetables.
  • Stay Hydrated: Aim for at least 8 cups of water a day—more if you exercise heavily.
  • Get Enough Sleep: Adults need 7-9 hours of quality sleep per night to support metabolism, recovery, and overall health.
  • Stay Active: Even light daily activities—like taking the stairs or walking breaks—help increase total daily energy expenditure.
