TDEE Calculator
Estimate how many calories your body uses each day based on your measurements and activity level.
Your Measurements
Choose the activity level that best describes your typical week. Estimates are intended for adults ages 20–100.
TDEE estimates the energy you use over a typical day, including rest and activity. Eating around this amount may maintain your current weight, but individual needs vary and estimates can be inaccurate.
Important: This calculator provides general educational estimates, not personalized medical or nutritional advice. It uses the adult Mifflin–St Jeor equation and standard activity multipliers, which may not reflect your actual energy expenditure. The equation uses male/female physiological constants and may not be appropriate for everyone. It is not designed for people under 20, pregnancy, breastfeeding, or situations requiring individualized nutrition care. Consult a qualified healthcare professional for personal guidance.
