About the TDEE Calculator

Total Daily Energy Expenditure (TDEE) is the number of calories you burn in a full day, including work, exercise and digestion. Eating about your TDEE keeps your weight stable.

How it is calculated

TDEE = BMR × activity factor. Common factors: sedentary 1.2, lightly active 1.375, moderately active 1.55, very active 1.725 and extra active 1.9.

Using the result

  • To lose weight, eat around 300–500 kcal below TDEE
  • To gain muscle, eat slightly above it
  • Recalculate as your weight changes
