Total Energy Expenditure

The Total Daily Energy Expenditure calculator computes the daily calories burned by a person based on their Basal Metabolic Rate and their level of activity.

INSTRUCTIONS: Choose units and enter the following.

• (h) height 
• (w) weight 
• (a) age
• (g) gender 
• (AL) Activity Level

Total Daily Energy Expended(TDEE):  The calculator returns food calories per day (kcal).  However, this can be automatically converted to compatible units via the pull-down menu

The Math / Science

The Total Energy Expenditure formula is as follows:

   TDEE = BMR * AL-Factor

where:

• TDEE = Total Daily Energy Expended
• BMR = Basal Metabolic Rate
• AL-Factor = Activity Level Factor

The Activity Level Factor is as follows:

• sedentary: 1.2
• light: 1.275
• moderate: 1.55
• very active: 1.725
• extremely active: 1.9

The Base Metabolic Rate (BMR) formula computes the daily calories consumed by a person at rest based on their gender (g), age (a), weight(w) and height (h).  The formula is based on the Mifflin St Jeor equation.
