TDEE Calculator
Compare estimated total daily energy expenditure across different activity-level assumptions.
What this answers:
- Roughly how many calories would I burn per day at a given assumed activity level?
Activity multipliers are approximate model assumptions, not validated individual measurements. They are not an extension of the original Mifflin-St Jeor study. Real measured expenditure can differ.

How it's calculated
TDEE = resting energy × activity factor, using the same resting-energy formula.
Worked example
1,780 kcal/day resting × 1.55 (moderate activity) = 2,759 kcal/day.
