The Consumer Price Index (CPI) is an indicator of the change in the average retail prices of a fixed basket of goods and services commonly purchased by households relative to a base year. It shows how much, on the average, prices of goods and services have increased or decreased from a particular reference period known as the base year. Since price is the cost or the amount of money for which something can be bought or sold, CPI therefore compares the current cost of certain goods and services with their cost at an earlier time.
