The TDEE Calculator estimates your Total Daily Energy Expenditure — the number of calories your body burns each day based on your metabolism and activity level.
Knowing your TDEE can help you determine how many calories to consume to lose weight, maintain weight, or build muscle.
What Is Total Daily Energy Expenditure (TDEE)?
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns each day. It includes:
• Basal Metabolic Rate (BMR)
• Calories burned through physical activity
• Calories used for digestion
This calculator first estimates your BMR using the Mifflin-St Jeor formula and then multiplies it by your activity level to estimate your daily calorie needs.
Example TDEE Calculation
For example:
A 30-year-old male
Weight: 80 kg
Height: 180 cm
Moderate exercise (3–5 days per week)
Estimated BMR ≈ 1,780 calories
TDEE = BMR × Activity Level
TDEE ≈ 1,780 × 1.55 ≈ 2,759 calories per day
This means consuming around 2,759 calories would maintain body weight.
