Free TDEE Calculator – Calculate Your Total Daily Energy Expenditure Online
Total Daily Energy Expenditure (TDEE) represents the total number of calories your body burns in a single day, combining your Basal Metabolic Rate (BMR) with your physical activity level. Understanding your TDEE is the cornerstone of any effective nutrition plan, whether your goal is weight loss, muscle gain, or simply maintaining your current physique. Unlike static calorie recommendations, TDEE provides a personalized estimate tailored to your unique body composition and lifestyle.
Our free TDEE calculator uses the Mifflin-St Jeor equation, widely recognized by nutritionists and sports scientists as the most accurate formula for estimating resting metabolic rate. The equation takes into account your weight, height, age, and gender to calculate your BMR, then multiplies it by an activity factor ranging from sedentary (office worker with no exercise) to very active (intense training twice daily). This approach gives you a reliable baseline for planning your daily calorie intake.
Once you know your TDEE, you can create a strategic calorie deficit or surplus to reach your goals. For safe weight loss, most experts recommend a moderate deficit of 500 calories per day, which translates to roughly 0.5 kg (1 lb) of fat loss per week. For lean muscle gain, a modest surplus of 250-500 calories above TDEE, paired with resistance training, is typically recommended. Our calculator instantly shows you calorie targets for five different goals, from aggressive fat loss to rapid muscle building.
Keep in mind that TDEE is an estimate and individual results may vary based on genetics, hormonal factors, body composition, and the thermic effect of food. It is best used as a starting point. Track your weight and energy levels over 2-3 weeks, then adjust your intake up or down by 100-200 calories as needed. For personalized advice, consult a registered dietitian or healthcare professional who can factor in your medical history and specific requirements.
