Calculate Your TDEE

TDEE (Total Daily Energy Expenditure) is the total number of calories your body burns in a 24-hour period, including your Basal Metabolic Rate (BMR) plus calories burned through physical activity, digestion, and thermogenesis. Understanding your TDEE is crucial for effective weight management, whether you want to lose weight, maintain your current weight, or gain muscle mass. Our TDEE calculator helps you determine the exact calorie intake needed to achieve your fitness goals.

Our TDEE calculator automatically selects the most appropriate calculation method based on your provided data. We primarily use the Mifflin-St Jeor equation, which clinical studies show is the most accurate formula for calculating Total Daily Energy Expenditure, with an accuracy rate of approximately 90% for healthy adults. This makes our TDEE calculator more reliable than those using older formulas like Harris-Benedict. While no TDEE calculator can be 100% perfect due to individual metabolic variations, our calculator provides the most scientifically-backed estimates available.

To use our TDEE calculator, you need to provide your age, gender, height (in cm), weight (in kg), and activity level. These factors directly impact your Basal Metabolic Rate and overall Total Daily Energy Expenditure. The more accurate your input information, the more precise your TDEE calculation will be. Our calculator guides you through selecting the appropriate activity level for the most accurate results.

Our TDEE calculator offers five activity levels: Sedentary (1.2x BMR) for desk jobs with little exercise, Lightly Active (1.375x BMR) for light exercise 1-3 days/week, Moderately Active (1.55x BMR) for moderate exercise 3-5 days/week, Very Active (1.725x BMR) for hard exercise 6-7 days/week, and Extra Active (1.9x BMR) for very hard exercise or physical job. Choose the level that best represents your average weekly activity for accurate TDEE calculation.

Our TDEE calculator provides general recommendations for different fitness goals as reference only. For weight loss, a common approach is consuming 300-500 calories below your calculated TDEE. For muscle gain, eating 300-500 calories above your TDEE may be beneficial. For weight maintenance, consume calories close to your TDEE. Please note that individual needs vary significantly, and these are general guidelines only. We strongly recommend consulting with healthcare professionals or registered dietitians before making significant dietary changes, especially if you have underlying health conditions. The calculator's macronutrient breakdowns are for informational purposes and should not replace professional nutritional advice.

We recommend recalculating your TDEE every 2-4 weeks during active fitness programs, or whenever significant changes occur in your weight (5+ pounds), activity level, or body composition. As you lose or gain weight, your BMR changes, which affects your Total Daily Energy Expenditure. Regular TDEE recalculation ensures your calorie targets remain accurate for continued progress toward your fitness goals.

BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic physiological functions like breathing, circulation, and cell production. TDEE (Total Daily Energy Expenditure) includes your BMR plus additional calories burned through physical activity, exercise, and daily movements. Our TDEE calculator shows both values, helping you understand how activity level impacts your total calorie needs.

Yes, our TDEE calculator is designed to accommodate all activity levels, including athletes and highly active individuals. The 'Extra Active' setting (1.9x BMR) is specifically designed for people with very high activity levels, including competitive athletes, those with physical jobs, or individuals who exercise intensely twice daily. However, elite athletes may need individual assessment from sports nutritionists for optimal precision.

We take your privacy very seriously. All TDEE calculations are performed locally on your device using client-side JavaScript - your personal information (age, weight, height, gender) never leaves your device or gets transmitted to our servers. We do not collect, store, or share any personal health data. Our website may use anonymous analytics to improve user experience, but no personally identifiable information is tracked.
