TDEE Calculator

Estimate total daily energy expenditure using the Mifflin–St Jeor equation, then calibrate the estimate against your real two-week weight trend.

ESTIMATED DAILY BURN
2,663 kcal/day

Estimated resting needs: 1,718 kcal/day. For gradual fat loss, a cautious starting point is near 2,263 kcal, followed by real-world calibration.

What TDEE means

Total Daily Energy Expenditure combines estimated resting metabolic needs with movement, work, daily activity, and exercise. The calculator first estimates basal metabolic rate, then applies an activity multiplier.

MIFFLIN–ST JEORBMR × activity factor = estimated TDEE

Activity factors

LevelFactorGeneral description
Sedentary1.2Mostly seated, little planned exercise
Lightly active1.375Light exercise about 1–3 days/week
Moderately active1.55Moderate exercise about 3–5 days/week
Very active1.725Hard exercise about 6–7 days/week

Activity categories are broad. Step count, job demands, training volume, body size, and individual metabolism can make the same label inaccurate for two different people.

How to calibrate your result

  1. Choose a consistent daily intake near the estimate.
  2. Track morning body weight under similar conditions for at least two weeks.
  3. Compare weekly averages, not single weigh-ins.
  4. Adjust gradually if the trend differs from your goal.

Do not treat the output as a prescription. Pregnancy, adolescence, eating-disorder recovery, medical conditions, and some medications require individual professional guidance.
