Utility is the satisfaction or happiness that a person derives from the use or consumption of goods and services. People consume goods and services because they provide them with some form of benefit or satisfaction. For example, someone might purchase a chocolate bar because they enjoy the taste and it makes them happy. The satisfaction that they receive from eating the chocolate bar is the utility that they derive from it. In economics, utility is often used as a measure of the overall satisfaction or happiness that a person derives from the consumption of goods and services. Utility is a subjective measure, meaning that it varies from person to person and cannot be measured directly. Economists use the concept of utility to explain how people make choices about what goods and services to consume. People will generally choose to consume goods and services that provide them with the highest level of utility or satisfaction, given their budget constraints and other limitations.
