Free TDEE Calculator: Total Daily Energy Expenditure
Calculate your Total Daily Energy Expenditure and personalized calorie needs
The Total Daily Energy Expenditure (TDEE) calculator estimates how many calories you burn per day. It calculates your Basal Metabolic Rate (BMR) using the Mifflin-St Jeor Equation and then applies an activity factor to determine your total daily calorie requirements.

Understanding TDEE Components
Basal Metabolic Rate (BMR)
Your BMR represents the calories your body needs for essential functions at complete rest. This includes breathing, blood circulation, cell production, and brain function. BMR typically accounts for about 60-70% of your total daily energy expenditure.
Thermic Effect of Food (TEF)
TEF is the energy your body uses to digest, absorb, and process the food you eat. It accounts for approximately 10% of your total energy expenditure. Protein has the highest thermic effect (20-30% of calories consumed), followed by carbohydrates (5-10%) and fats (0-3%).
Non-Exercise Activity Thermogenesis (NEAT)
NEAT refers to the energy expended during non-exercise physical activities like standing, walking, fidgeting, and other daily movements. This can vary significantly between individuals and can account for 15% or more of your daily energy expenditure.
Exercise Activity Thermogenesis (EAT)
EAT represents the calories burned during intentional exercise and typically accounts for about 5% of total energy expenditure for the average person. However, this can be significantly higher for very active individuals or athletes.
How to Increase Your Daily Energy Expenditure
Add Strength Training
Building muscle increases your BMR as muscle tissue burns more calories at rest than fat tissue. Aim for 2-3 strength training sessions per week targeting all major muscle groups.
Increase NEAT
Take the stairs, walk or bike instead of driving, stand rather than sit, clean your house, or simply fidget more. These small activities can significantly increase your energy expenditure over time.
Optimize Protein Intake
Increase the protein content of your diet to boost TEF. Protein requires more energy to digest than fats or carbohydrates, potentially increasing your metabolic rate by 15-30% during digestion.

Frequently Asked Questions
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the number of calories your body needs at complete rest to maintain vital functions. TDEE (Total Daily Energy Expenditure) includes your BMR plus additional calories burned through digestion, daily activities, and exercise.
How accurate is this TDEE calculator?
This calculator provides an estimate based on the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. However, individual metabolic rates can vary by up to 10-15%. For increased accuracy, you may need to track your calorie intake and weight changes over time to adjust your personal TDEE.
How should I use these calorie targets?
For weight maintenance, aim to consume approximately your TDEE in calories each day. For weight loss, create a moderate calorie deficit (typically 500 calories below TDEE). For muscle gain, a slight calorie surplus (about 250 calories above TDEE) combined with strength training is recommended.
Does muscle really burn more calories than fat?
Yes, muscle tissue is metabolically more active than fat tissue. One pound of muscle burns approximately 6-10 calories per day at rest, while one pound of fat burns only 2-3 calories. While this difference might seem small, it can add up significantly with increased muscle mass.
