About Calorie calculator

The Calorie Calculator estimates your Total Daily Energy Expenditure (TDEE) — the number of calories your body burns each day — based on age, gender, height, weight, and activity level, using the Mifflin-St Jeor equation which is widely considered the most accurate for most people. From your TDEE, it calculates adjusted calorie targets for weight loss (typically a 20% deficit), maintenance, and muscle gain (a 10–20% surplus). Understanding your TDEE is the single most important number in any evidence-based approach to nutrition and body composition.
