A medical device system determines and displays relative energy expenditure information for programmable parameter values. The system establishes a programmable parameter and multiple values of the parameter to be compared. A module performs a measurements for each of the multiple values and related to energy expenditure of a battery of an implantable medical device when operating according to each of the multiple parameter values. An energy expenditure for each of the values is computed using the measurements, and a graphical user interface is generated for displaying information corresponding to the computed energy expenditure for multiple parameter values.
