What is Utility?

/juːˈtɪlɪti/

The total satisfaction, benefit, or value that a consumer derives from consuming a good or service. The central concept in microeconomics for modelling human preferences and decision-making.

Everyday Example

Choosing between a £5 coffee and a £5 book isn't about money — it's about which gives you more utility. Utility is your personal, subjective measure of value. Economics assumes you always choose whichever option maximises it.

publicReal-World Application

Netflix measures utility through "completion rate" and "hours watched per subscriber" rather than profit per title. A show might lose money to produce but add enormous utility — and therefore retention — to subscribers.

Did you know?

Jeremy Bentham introduced utility theory in 1789 as the foundation of utilitarianism: the moral philosophy that the right action is whichever produces the greatest utility (happiness) for the greatest number of people.

Key Insight

Utility is unmeasurable and non-comparable between people. You can't add up my utility and yours. This is the fundamental problem with policies that claim to maximise "total welfare" — they require assumptions that can't be verified.
