Cost of living measures the amount of money required to maintain a standard of living in a particular place. It aggregates prices for housing, food, transportation, health care, education, and other everyday items, then compares them to a base location—often a national capital. By translating diverse price data into a single index, the metric lets analysts, employers, and individuals gauge how expensive or affordable a city or country truly is.
The index is usually expressed as a percentage of the base location: a score of 110 means living costs are 10 % higher, while 90 indicates they are 10 % lower. Governments use it to adjust wages and benefits, businesses reference it when setting salaries for remote teams, and travelers rely on it to budget trips. Understanding the drivers behind the numbers helps you interpret what the figure really says about your daily life.
