TDEE Calculator

Find your Total Daily Energy Expenditure (maintenance calories) using the Mifflin-St Jeor equation and activity multiplier.

The formula this calculator uses

TDEE Calculator

BMR (Mifflin-St Jeor) then TDEE = BMR × activity factor
1.2 sedentary … 1.9 extra active

Example: 30y, male, 175 cm, 70 kg, 1.55 activity → TDEE ≈ 2,590 kcal

Using TDEE for goals

Once you know maintenance, a moderate deficit (10–20%) supports fat loss while a small surplus supports muscle gain. Extreme deficits are harder to sustain and can cost muscle and energy.

Frequently asked questions

What does TDEE stand for?

Total Daily Energy Expenditure — the total calories you burn in a day including exercise and daily activity.

How often should I recalculate?

Whenever your weight changes by more than a few kilograms or your training volume changes significantly.

Why is my weight not changing at TDEE?

Estimates have error. Track weight for 2–3 weeks and adjust intake up or down by 100–200 kcal as needed.

Is TDEE the same as maintenance calories?

Yes. Eating at TDEE should keep weight stable over time.
