TDEE Calculator: Your Complete Guide to Total Daily Energy Expenditure
⚡ Discover Your True Energy Needs?
Use our comprehensive TDEE calculator to understand exactly how many calories your body burns each day. Whether you're losing weight, building muscle, or maintaining your current physique, knowing your Total Daily Energy Expenditure is the foundation of effective nutrition and achieving your health goals.
Understanding TDEE: The Foundation of Nutrition Planning
What Is Total Daily Energy Expenditure (TDEE)?
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a 24-hour period, including all activities from basic bodily functions to exercise and daily movement. Think of it as your body's "daily energy budget"—the amount of fuel you need to maintain your current weight and activity level.
Your TDEE is calculated by combining your Basal Metabolic Rate (BMR) with your activity level. BMR accounts for 60-75% of your daily calorie burn, while physical activity and daily movement make up the rest. Understanding your TDEE helps you create precise calorie targets for any fitness goal.
💡 Pro Tip:
Your TDEE is your nutrition North Star. Eat below it to lose weight, at it to maintain, or above it to gain. It's the most important number for any nutrition plan.

Understanding TDEE Standards: What's Normal?
📊 Typical TDEE Ranges by Activity
Sedentary (1,600-2,400 kcal)
Office work, minimal exercise
Moderate (2,000-3,000 kcal)
Regular exercise 3-5 days/week
Active (2,500-3,500 kcal)
Daily exercise or physical job
Very Active (3,000-4,000+ kcal)
Athletes, heavy physical work
🎯 Goal-Based Calorie Adjustments
*Adjust based on results and goals
Expert Tips for Accurate TDEE Tracking
💡 Best Practices
- ✓Be honest about activity: Overestimating leads to weight gain
- ✓Track your weight: Monitor changes over 2-3 weeks
- ✓Adjust gradually: Make small changes based on results
- ✓Consider body composition: Muscle burns more than fat
⚠️ Common Mistakes
- ✗Overestimating activity: Most people are moderately active
- ✗Not tracking progress: Results tell the real story
- ✗Ignoring individual factors: Genetics and metabolism vary
- ✗Being too rigid: Allow for daily variations
Understanding Your Results: What the Numbers Mean
📊 Decoding Your TDEE Data
Your TDEE calculator results provide a personalized energy blueprint. Here's what each component means:
Basal Metabolic Rate (BMR)

Frequently Asked Questions
How accurate is the TDEE calculator?
Our calculator uses the scientifically-proven Mifflin-St Jeor equation, which is considered the gold standard for BMR calculation. However, individual metabolism can vary by ±10-15%. For maximum accuracy, track your weight changes over 2-3 weeks and adjust accordingly.
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the calories you burn at complete rest, while TDEE (Total Daily Energy Expenditure) includes all your daily activities. TDEE = BMR × Activity Level. BMR is about 60-75% of your TDEE, with the rest coming from physical activity and daily movement.
How often should I recalculate my TDEE?
Recalculate whenever your weight changes significantly (5+ lbs), activity level changes, or you switch goals. Also reassess every 4-6 weeks to ensure your calorie target aligns with your current progress and needs.
Can I use this for weight loss or muscle gain?
Absolutely! Use your TDEE as the baseline. For weight loss, eat 300-500 calories below TDEE. For muscle gain, eat 250-500 calories above TDEE. Monitor your progress and adjust based on results.
Should I use metric or imperial units?
The calculator supports both systems and will give you the same results after conversion. Choose whichever system you're most comfortable with. The calculator automatically converts between kg/lbs and cm/inches.
Does age affect TDEE?
Yes, metabolism typically slows with age due to decreased muscle mass and hormonal changes. The calculator accounts for this in the BMR formula. Older adults may need to be more mindful of activity levels and muscle maintenance.
What if my TDEE seems too high or low?
TDEE can vary significantly based on individual factors like genetics, body composition, and activity level. If your calculated TDEE seems off, track your weight changes over 2-3 weeks while eating at that level. Adjust based on actual results rather than just the calculation.
