How This Calculation Works
TDEE includes resting energy and estimated daily activity. We use 10 × kg + 6.25 × cm − 5 × age, plus 5 for male or minus 161 for female, then multiply by the activity factor. Activity factors are separate planning assumptions.
Example
Male, 30 years, 180 cm, 80 kg: resting energy = 1,780 kcal. At 1.375, maintenance = 2,447.5 kcal/day.

How accurate is this estimate?
Activity and individual differences affect energy needs. This equation estimates resting energy rather than measuring metabolism.
