Use this free TDEE calculator to estimate your daily calorie needs.
Enter the following information
- Age
- Gender
- Height
- Weight
- Activity level
Your results will show
- Maintenance calories (your TDEE)
- Calories for fat loss
- Calories for weight maintenance
- Calories for muscle gain
This estimate gives you a starting point for your nutrition plan. You can adjust calories after tracking progress for a few weeks.
Your Total Daily Energy Expenditure (TDEE) is the total number of calories your body burns in a 24-hour period. It represents your daily maintenance calories, the number of calories you need to eat to maintain your current body weight.
A TDEE calculator estimates your daily calorie burn based on factors like age, weight, height, gender, and activity level. Once you know your TDEE, you can adjust your calorie intake to lose fat, maintain weight, or build muscle.
Key Takeaways
- TDEE is the total number of calories your body burns in a day
- It includes metabolism, digestion, exercise, and everyday movement
- A TDEE calculator helps estimate your maintenance calories
- To lose weight, eat below your TDEE
- To gain muscle, eat above your TDEE

What Is TDEE?
TDEE (Total Daily Energy Expenditure) is the total amount of energy your body burns in one day.
Your body constantly burns calories to support vital processes such as:
- breathing
- circulating blood
- regulating body temperature
- maintaining organ function
But your daily calorie burn also includes movement and digestion. When all these processes are combined, they form your total daily energy expenditure.
Understanding your TDEE helps you determine how many calories you should eat each day based on your health and fitness goals.
The 4 Components of TDEE
Your daily calorie burn comes from four main sources.
1. Basal Metabolic Rate (BMR)
Basal Metabolic Rate (BMR) represents the calories your body burns while completely at rest.
It supports essential functions such as:
- breathing
- heart function
- brain activity
- hormone regulation
- cell repair
BMR usually accounts for 60–70% of your total daily calorie burn.
2. Thermic Effect of Food (TEF)
The Thermic Effect of Food is the energy your body uses to digest and process nutrients.
Digesting food requires energy, especially when consuming high-protein meals.
TEF typically contributes about 10% of your total calorie expenditure.
3. Exercise Activity Thermogenesis (EAT)
EAT represents calories burned during intentional exercise, such as:
- weight training
- running
- cycling
- sports
- gym workouts
The more frequently you exercise, the more this component contributes to your TDEE.
4. Non-Exercise Activity Thermogenesis (NEAT)
NEAT refers to calories burned through everyday movement outside structured exercise.
Examples include:
- walking
- standing
- cleaning
- climbing stairs
- fidgeting
NEAT can vary greatly between individuals and significantly influence daily calorie expenditure.
How to Calculate TDEE
Most TDEE calculators estimate calorie expenditure using a two-step method:
- Calculate your Basal Metabolic Rate (BMR)
- Multiply your BMR by an activity multiplier
This method provides a reliable estimate of your daily calorie needs.
Step 1: Calculate Your BMR
The most widely used formula for estimating BMR is the Mifflin-St Jeor equation.
For Men
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age + 5
For Women
BMR = 10 × weight (kg) + 6.25 × height (cm) − 5 × age − 161
This formula estimates how many calories your body burns while at complete rest.
Step 2: Apply an Activity Multiplier
After calculating your BMR, multiply it by a factor based on your activity level.
| Activity Level | Multiplier |
| Sedentary (little exercise) | 1.2 |
| Light exercise (1–3 days/week) | 1.375 |
| Moderate exercise (3–5 days/week) | 1.55 |
| Very active (6–7 days/week) | 1.725 |
| Extremely active / athletes | 1.9 |
Example TDEE Calculation
If your BMR is 1600 calories and you exercise moderately:
1600 × 1.55 = 2480 calories
Your estimated TDEE would be about 2480 calories per day.
TDEE vs BMR: What’s the Difference?
Many people confuse BMR and TDEE, but they measure different aspects of energy expenditure.
| Metric | Meaning |
| BMR | Calories burned while resting |
| TDEE | Total calories burned daily |
| Includes activity | No |
| Includes exercise | No |
| Used for | Metabolism baseline |
In simple terms:
BMR = calories burned if you stayed in bed all day
TDEE = calories burned during your normal daily life
Why Knowing Your TDEE Matters
Your TDEE determines how many calories you should eat depending on your goals.
For Weight Loss
To lose fat, you need to create a calorie deficit.
Most people reduce their calorie intake by 300–500 calories below TDEE.
This typically results in gradual weight loss of about 0.5 kg (1 lb) per week.
For Weight Maintenance
If you want to maintain your current body weight, consume calories close to your TDEE.
This keeps your calorie intake and energy expenditure balanced.
For Muscle Gain
To build muscle, your body needs additional energy.
Eating 200–400 calories above your TDEE can support muscle growth while minimizing fat gain.
Strength training is essential to ensure those extra calories contribute to muscle development.
How Accurate Is a TDEE Calculator?
TDEE calculators provide estimates rather than exact calorie requirements.
Your true calorie needs depend on several factors, including:
- metabolism
- muscle mass
- hormones
- genetics
- daily movement patterns
For the most accurate results, treat your TDEE as a starting point.
Track your food intake and weight changes for 2–3 weeks, then adjust calories if needed.
Tips to Use Your TDEE Effectively
To get the most benefit from your TDEE estimate, follow these best practices.
Track Your Food Intake
Use a calorie tracking app to monitor your daily nutrition.
Monitor Your Weight Trends
Weigh yourself consistently and track weekly averages rather than daily fluctuations.
Adjust Calories Gradually
If progress stalls, adjust calories by 100–200 calories at a time.
Combine Nutrition With Exercise
Strength training and regular physical activity help improve metabolism and maintain lean muscle.
Final Thoughts
Your Total Daily Energy Expenditure is one of the most important numbers in nutrition and fitness.
By estimating how many calories your body burns each day, you can create a personalized diet strategy for fat loss, weight maintenance, or muscle gain.A TDEE calculator provides a practical starting point, but long-term success depends on tracking progress and adjusting calorie intake over time.
Frequently Asked Questions
What is TDEE?
TDEE stands for Total Daily Energy Expenditure, which represents the total calories your body burns in a 24-hour period through metabolism, digestion, and physical activity.
How do I calculate my TDEE?
You can calculate TDEE by estimating your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor formula and multiplying it by an activity factor.
Is a TDEE calculator accurate?
TDEE calculators provide an estimate. The most accurate method is to track your calorie intake and body weight for several weeks and adjust your calorie target accordingly.
Should I eat below my TDEE to lose weight?
Yes. Consuming 300–500 calories below your TDEE helps create a calorie deficit needed for gradual and sustainable fat loss.
What is the difference between BMR and TDEE?
BMR measures calories burned at rest, while TDEE includes all daily activity, digestion, and exercise.
