A TDEE (Total Daily Energy Expenditure) Calculator estimates how many calories you burn per day based on age, weight, height, and activity level.
Enter your gender, age, weight, height, and activity level. The calculator shows your TDEE and calorie recommendations for different goals.
TDEE stands for Total Daily Energy Expenditure. It represents the total number of calories your body burns in a day while performing basic functions (like breathing) and physical activities.
This calculator first determines your Basal Metabolic Rate (BMR)—the calories you burn at complete rest—using a specific formula (e.g., Mifflin-St Jeor or Harris-Benedict). It then multiplies your BMR by an Activity Factor based on how much exercise you do to find your TDEE.
The Harris-Benedict formula is older and was derived from data in the early 20th century. The Mifflin-St Jeor formula is newer and generally considered more accurate for modern populations, though Harris-Benedict is still widely used.
Choose the level that best matches your average week. Be honest; if you have a desk job but go to the gym 3 times a week, select 'Lightly Active' or 'Moderately Active' rather than 'Sedentary'. Do not count specific workout sessions twice.
To lose weight, you generally need to consume fewer calories than your TDEE. A common approach is to create a deficit of 500 calories per day, which theoretically leads to a loss of approximately 0.5 kg (1 lb) per week.
The standard TDEE calculation relies on weight, height, age, and gender. If you have an extremely high muscle mass or body fat percentage, standard formulas may be slightly off, though they remain effective estimates for the general population.
