TDEE Calculator – Find Your Daily Calorie Needs

What is TDEE?

Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a day, including all physical activities and bodily functions. It's the foundation of any successful nutrition plan, whether you're looking to lose weight, maintain your current physique, or build muscle mass.

How It's Calculated

Our TDEE calculator uses the scientifically-validated Mifflin-St Jeor equation to determine your Basal Metabolic Rate (BMR), then applies activity multipliers to account for your daily movement and exercise levels. This approach provides the most accurate estimate of your daily calorie needs based on current research.

Why It Matters

Understanding your TDEE eliminates the guesswork from nutrition planning. It gives you a precise starting point for creating a calorie deficit (for weight loss) or surplus (for muscle gain). Without this baseline, you're essentially flying blind with your nutrition strategy.
