TDEE Calculator: Know Exactly How Many Calories You Burn
Estimate your Total Daily Energy Expenditure (TDEE) and discover exactly how many calories your body burns each day — then use that number to lose fat, gain muscle, or maintain your weight.
Understanding how many calories your body burns each day is one of the most important steps toward achieving your health and fitness goals. Whether you want to lose weight, build muscle, or maintain your current body weight, knowing your Total Daily Energy Expenditure (TDEE) provides the foundation for making informed nutrition decisions.
Our free TDEE Calculator estimates the total number of calories your body burns in a typical day by considering your Basal Metabolic Rate (BMR) and your daily activity level. Instead of guessing how much you should eat, you can use accurate calculations to create a personalized nutrition strategy.

What Is TDEE?
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns during a 24-hour period.
It includes:
- Basal Metabolic Rate (BMR)
- Physical activity
- Exercise
- Walking
- Digestion (Thermic Effect of Food)
Your TDEE changes depending on your age, weight, height, sex, body composition, and daily activity level.
How Is TDEE Calculated?
The calculation follows two main steps.
Step 1: Calculate BMR
Your Basal Metabolic Rate (BMR) estimates the calories your body needs at complete rest to maintain essential functions such as breathing, circulation, and organ function. Learn more with the BMR Calculator.
Step 2: Apply an Activity Multiplier
| Activity Level | Multiplier |
|---|---|
| Sedentary (little or no exercise) | 1.20 |
| Lightly Active (1–3 days/week) | 1.375 |
| Moderately Active (3–5 days/week) | 1.55 |
| Very Active (6–7 days/week) | 1.725 |
| Extra Active (physical job or twice daily) | 1.90 |
TDEE Formula
TDEE = BMR × Activity Factor
Example Calculation
| Input | Value |
|---|---|
| Age | 30 |
| Sex | Male |
| Height | 180 cm |
| Weight | 80 kg |
| Activity Level | Moderately Active |
| Estimated BMR | 1,780 kcal/day |
| Activity Multiplier | 1.55 |
| Estimated TDEE | 2,759 kcal/day |
This means approximately 2,760 calories are required each day to maintain current body weight. Use the TDEE Calculator above to get your own personalised estimate instantly.
Why Is TDEE Important?
Knowing your TDEE helps you:
- Lose body fat efficiently
- Build lean muscle
- Maintain your current weight
- Plan meal portions accurately
- Improve athletic performance
- Avoid overeating
- Prevent under-eating
- Set realistic nutrition goals
TDEE for Weight Loss
To lose weight, consume fewer calories than your TDEE. General recommendations:
| Goal | Daily Calorie Intake |
|---|---|
| Slow Fat Loss | TDEE − 250 kcal |
| Moderate Fat Loss | TDEE − 500 kcal |
| Aggressive Fat Loss | TDEE − 750 kcal |
TDEE for Muscle Gain
To support muscle growth, increase your daily calorie intake above your TDEE. Common surplus ranges:
- +200 kcal/day for a lean bulk
- +300 kcal/day for steady muscle gain
- +500 kcal/day for a more aggressive bulk
Combine a calorie surplus with progressive strength training and adequate protein intake for best results.
TDEE for Weight Maintenance
If your goal is maintaining your current weight, set your daily calorie intake equal to your TDEE. Monitor your weight over several weeks and adjust if your activity levels change significantly.
Factors That Influence TDEE
Your daily energy expenditure is affected by a wide range of factors:
- Age
- Sex
- Height
- Weight
- Muscle mass
- Physical activity level
- Exercise intensity and frequency
- Hormonal status
- Genetics
- Underlying health conditions
BMR vs TDEE
| BMR | TDEE |
|---|---|
| Calories burned at complete rest | Total calories burned throughout the entire day |
| Includes only basic body functions | Includes physical activity and exercise |
| Lower numerical value | Higher numerical value (always above BMR) |
| Starting point for calculations | The daily calorie target you plan against |
Think of BMR as your body's minimum fuel requirement. TDEE builds on top of it by adding every movement you make throughout the day. Use the BMR Calculator to see your resting figure first, then apply an activity factor.
Who Should Use a TDEE Calculator?
A TDEE calculator is useful for anyone who wants to understand their energy needs, including:
- Individuals aiming to lose weight
- Athletes optimising performance nutrition
- Bodybuilders planning a bulk or cut
- Personal trainers designing client programmes
- Dietitians and nutritionists
- Fitness beginners building healthy habits
- Anyone planning daily calorie intake
Tips for Improving Energy Balance
- Exercise regularly — even moderate activity raises your TDEE significantly
- Increase daily movement (NEAT — non-exercise activity thermogenesis)
- Build lean muscle to raise your resting metabolism over time
- Eat sufficient protein (supports muscle retention during a deficit)
- Sleep 7–9 hours per night (poor sleep disrupts hunger hormones)
- Stay well hydrated throughout the day
- Track calorie intake consistently for at least 2–4 weeks
Frequently Asked Questions
Is TDEE the same as BMR?
No. BMR measures calories burned at complete rest, while TDEE includes all physical activity, exercise, and the energy used to digest food (Thermic Effect of Food). TDEE is always higher than BMR.
How accurate is a TDEE calculator?
It provides a well-established estimate based on validated equations (such as the Mifflin–St Jeor equation) and activity multipliers. Individual needs may vary depending on body composition, genetics, and other factors. Use it as a starting point and adjust based on real-world results.
Should I eat exactly my TDEE?
If maintaining your current weight is your goal, eating at TDEE is a useful starting point. Adjust upward for muscle gain and downward for fat loss. Consult a qualified professional if you have specific medical or nutritional needs.
How often should I recalculate my TDEE?
Every 4–6 weeks, or after significant changes in body weight (more than 2–3 kg) or activity level. As your weight changes, so does your BMR and therefore your TDEE.
What is the difference between TDEE and maintenance calories?
TDEE and maintenance calories refer to the same concept — the total daily calorie expenditure needed to keep your current body weight stable.
Can TDEE change over time?
Yes. TDEE changes with age, weight, activity level, and body composition. Muscle mass increases TDEE; sedentary periods and aging can decrease it. Recalculate periodically for accuracy.
Is the CalcWisee TDEE Calculator free?
Yes. All CalcWisee health calculators are completely free to use with no registration required.
What activity level should I choose?
Choose the level that best reflects your typical week — not your best week. If you sit at a desk most of the day and exercise 2–3 times per week, "Lightly Active" is usually most accurate. Overestimating activity level is a common reason TDEE calculations feel too high.
