According to Wikibooks, Utility is a term used by economists to describe the measurement of "useful-ness" that a consumer obtains from any good. Utility may measure how much one enjoys a movie, or the sense of security one gets from buying a deadbolt. The utility of any object or circumstance can be considered. Some examples include the utility from eating an apple, from living in a certain house, from voting for a specific candidate, from having a given wireless phone plan. In fact, every decision that an individual makes in their daily life can be viewed as a comparison between the utility gained from pursuing one option or another.
Example: In the morning, Sally’s mother offers to take her to school. Sally can either walk or drive. Sally's mother considers the benefits of exercise and fresh air, which compose the utility she would derive from walking, and also considers the time savings and comfort of driving. Sally's mother decides to drive.
