Basal Energy Expenditure (BEE equation)

New! AI-Edition of the Basal Energy Expenditure: ? This AI-powered medical calculator interprets your clinical inputs and provides both the computed result and a brief clinical explanation. It helps clinicians quickly understand what the numbers mean in context, supporting faster, more informed decision-making.

To calculate BEE for a specific patient, please provide:

  • Age in years
  • Sex (male or female)
  • Height in cm (or in inches, clearly labeled)
  • Weight (kg or lbs)

Basal Energy Expenditure (BEE) determination
Basal energy expenditure (BEE): the amount of energy required to maintain the body's normal metabolic activity, i.e. respiration, maintenance of body temperature etc.
Patient age:       Sex:
Patient Height: 
Patient weight:

Harris Benedict Equations:


BMR calculation for men (metric)
BMR = 66.47 + ( 13.75 x weight in kg ) + ( 5.003 x height in cm ) - ( 6.755 x age in years )


BMR calculation for women (metric)
BMR = 655.1 + ( 9.563 x weight in kg ) + ( 1.850 x height in cm ) - ( 4.676 x age in years )
