TDEE Calculator
Quick estimates using your height, weight, age, activity, or daily exercise.
These results are general estimates, not medical advice. Individual needs can vary. Consult a qualified healthcare professional before making health decisions.
How this tool works
TDEE is an estimate of the energy your body may use in a day. It combines a basal metabolic rate estimate with a selected activity factor.
Important limitations
- Activity categories are broad and cannot measure your exact daily movement.
- Illness, pregnancy, medication, training load and body composition can change individual needs.
- Treat the result as a starting estimate rather than a prescription.
Frequently asked questions
Is TDEE the same as a calorie target?
No. TDEE is an estimate of daily energy use. A personal nutrition target should consider health history, goals and professional guidance.
How often should I recalculate TDEE?
Recalculate when body weight, activity or training changes meaningfully. Avoid reacting to small day-to-day changes.
