TDEE Calculator
Estimate how many calories you expend across a typical day, including activity.
Your TDEE Result

Practical interpretation
Important: Estimate only—not medical advice.
How the TDEE Calculator works
Formula: TDEE = (10W + 6.25H − 5A + S) × activity factor, where S = +5 male or −161 female.
The Mifflin–St Jeor resting estimate is multiplied by 1.2–1.9 according to your selected activity level.
Assumptions and limits: Activity categories are broad and TDEE can differ on training and rest days. Results are estimates for education and planning, not medical advice.
How to use your result
Use the result as a starting point, not a pass-or-fail score. Keep your inputs consistent, observe relevant trends over time, and adjust only when the trend—not one day—shows the estimate does not fit your needs.
Body measurements and equation-based targets always contain uncertainty. If your result conflicts with symptoms, a diagnosis, medication guidance, pregnancy needs, an eating-disorder recovery plan, or instructions from your care team, follow your qualified health professional.
Frequently Asked Questions
What does the TDEE Calculator calculate?
It estimates estimate total daily energy expenditure from bmr and activity. from the information you enter. It is a planning and screening estimate, not a diagnosis or individualized medical prescription.
Which formula does this TDEE Calculator use?
This tool uses TDEE = (10W + 6.25H − 5A + S) × activity factor, where S = +5 male or −161 female.. The formula and every adjustment are shown on this page so you can understand the assumptions.
Can I use metric or imperial units?
Yes. Choose metric or imperial before entering body measurements. Imperial values are converted to kilograms and centimeters before the formula runs.
How accurate is this TDEE Calculator?
Population equations provide useful starting estimates but cannot measure your individual physiology. Activity categories are broad and TDEE can differ on training and rest days.
Who should not rely on this result alone?
Children, pregnant or breastfeeding people, competitive athletes with specialized needs, and anyone managing a medical condition should seek advice from a qualified health professional.
How often should I recalculate?
Recalculate when your body weight, activity, goal, or other relevant input changes meaningfully. Small day-to-day fluctuations generally do not warrant a new target.
Why might my result differ from another calculator?
Calculators may use different equations, activity factors, rounding rules, or definitions. Compare the documented methods rather than assuming one number is exact.
Is this result medical advice?
No. This educational estimate cannot account for diagnoses, medications, laboratory results, or clinical fluid and nutrition restrictions. Consult a licensed professional for personal medical advice.
