Calculate Your TDEE
About TDEE Calculator
TDEE stands for Total Daily Energy Expenditure, which represents the total number of calories your body burns in a day. This includes calories burned through basic bodily functions (BMR), physical activity, exercise, and the thermic effect of food.
Our TDEE calculator uses the scientifically validated Mifflin-St Jeor equation to calculate your Basal Metabolic Rate (BMR), then multiplies it by an activity factor to determine your total daily energy expenditure. This method is widely recognized for its accuracy in estimating daily calorie needs.

Frequently Asked Questions
What is the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the number of calories your body needs to maintain basic physiological functions at rest. TDEE includes BMR plus calories burned through physical activity, exercise, and daily movements.
How accurate is the TDEE calculator?
Our calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. However, individual variations in metabolism can affect accuracy by ±10-15%.
Should I eat exactly my TDEE calories?
Your TDEE represents maintenance calories. Eat at your TDEE to maintain weight, below it to lose weight, or above it to gain weight. Adjust based on your specific goals.
How often should I recalculate my TDEE?
Recalculate your TDEE when your weight changes significantly (5+ lbs/2+ kg), your activity level changes, or every 4-6 weeks during active weight management.
What if my actual results don't match the calculator?
Individual metabolism varies. If you're not seeing expected results after 2-3 weeks, adjust your calorie intake by 100-200 calories and monitor progress. Consider consulting a healthcare professional.
Can I use this calculator if I have health conditions?
While our calculator provides general estimates, individuals with medical conditions, eating disorders, or those taking medications should consult healthcare professionals before making significant dietary changes.
