About TDEE Calculator
Determine your daily maintenance calorie expenditure by combining Basal Metabolic Rate with physical activity multipliers (Sedentary, Light, Moderate, Very Active, Athlete). Breaks down basal, thermic effect of food, and active burn.
Key Capabilities & Features
- Calculates total daily maintenance energy across 5 standardized physical activity tiers (1.2 to 1.9)
- Energy budget decomposition: Basal BMR (~70%), Thermic Effect of Food TEF (~10%), Active & NEAT (~20%)
- Dynamic connection with Mifflin-St Jeor and Katch-McArdle metabolic engines
- Copyable daily energy expenditure metrics

Frequently Asked Questions
What does TDEE represent?
TDEE is the total number of calories your body burns in a 24-hour day through resting metabolism, digestion of food (TEF), and physical movement.
How do I use TDEE for weight loss?
Consuming 300-500 calories below your calculated TDEE creates a caloric deficit leading to approximately 0.3 to 0.5 kg (0.7 - 1.1 lbs) of fat loss per week.
