Cost of living is the amount of money required to cover basic expenses in a particular place and time. It encompasses housing, utilities, food, transportation, healthcare, education, and taxes, and it is influenced by price levels, wages, and consumption patterns. The concept is used to compare living standards across locations, and to guide wage setting, pensions, and policy decisions.

To measure cost of living, economists rely on price indices such as the consumer price index (CPI), regional price parities, and housing cost indices. These indices track changes in the prices of a representative basket of goods and services. Differences in baskets, quality adjustments, taxes, subsidies, and consumption patterns limit cross-location comparability.

Housing costs usually dominate the cost of living in many places, followed by transportation, food, and healthcare. Prices and availability of housing, energy costs, urban density, and local regulations strongly affect overall levels. Variations between cities, regions, and rural areas can be substantial even within the same country.

Cost of living is used in cost-of-living adjustments (COLAs) for wages, salaries, pensions, and contracts, and to assess regional economic disparities. It also informs households deciding where to relocate. Limitations include reliance on standardized baskets that may not reflect individual needs, time lags in data, and the challenge of separating price effects from changes in quality or choice.
