TDEE Calculator

Total Daily Energy Expenditure (TDEE) is a crucial concept in the realm of nutrition, fitness, and weight management. It represents the total number of calories your body burns in a day, taking into account your basal metabolic rate (BMR) and physical activity level. Understanding your TDEE is the key to setting realistic fitness and nutrition goals. In this comprehensive guide, we will explore what TDEE is, how to calculate it, the formula involved, and some secrets to make the most of this valuable knowledge.

What is TDEE?

TDEE is the total number of calories your body needs to maintain its current weight, factoring in all daily activities, exercise, and other energy-consuming processes. It's a vital metric if you want to lose, gain, or maintain weight effectively. Your TDEE is unique and influenced by various factors, including age, gender, weight, height, muscle mass, and activity level.

How to Calculate TDEE

Calculating your TDEE involves several steps. The most common method is using the Mifflin-St Jeor Equation, which is based on your BMR and activity level.

Step 1: Calculate Basal Metabolic Rate (BMR)

BMR represents the number of calories your body needs at rest. The Mifflin-St Jeor Equation to calculate BMR is as follows:

For Men: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (years) + 5

For Women: BMR = 10 * weight (kg) + 6.25 * height (cm) - 5 * age (years) - 161

Step 2: Determine Your Activity Level

Your activity level ranges from sedentary to very active, and you'll need to assign a value that best matches your daily routine:

  • Sedentary (little or no exercise)
  • Lightly active (light exercise or sports 1-3 days a week)
  • Moderately active (moderate exercise or sports 3-5 days a week)
  • Very active (hard exercise or sports 6-7 days a week)
  • Super active (very hard exercise or physical job)

Step 3: Calculate TDEE

Once you've determined your BMR and activity level, you can calculate your TDEE by multiplying your BMR by an activity factor:

TDEE = BMR * Activity Factor

TDEE Calculator Secrets

  1. Nutrition Control: Knowing your TDEE helps you create a calorie deficit (eating fewer calories than your TDEE) for weight loss or a surplus (eating more calories than your TDEE) for weight gain.

  2. Macro Balance: Understanding your TDEE allows you to tailor your macronutrient intake (carbs, proteins, and fats) to meet your specific fitness goals.

  3. Progress Tracking: Regularly calculating your TDEE can help you adjust your diet and exercise plan as your body changes, ensuring continued progress.

  4. Don't Overcomplicate: While precision is valuable, keep in mind that TDEE is an estimate. Start with a reasonable approach, and adjust as needed.

  5. Hormonal Factors: Factors like stress, sleep, and hormonal balance can influence your TDEE. Pay attention to these aspects for a more accurate estimate.

  6. Consult a Professional: For personalized guidance, especially if you have specific health concerns or unique fitness goals, consult with a registered dietitian or fitness expert.


Total Daily Energy Expenditure (TDEE) is an essential concept for anyone striving to manage their weight, improve their fitness, or meet specific nutrition goals. Understanding how to calculate your TDEE and utilizing this knowledge wisely can make a significant difference in your health and well-being. With the right approach and regular monitoring, you can harness the power of TDEE to achieve your fitness aspirations.
