The consumer price index (cpi) is a measure of the cost of living during a particular period. The cost of a standard basket of goods and services in a given year. Relative to the cost of the same basket of goods and services in the base year. 2010 is the base year for the cpi. Cpi is the ratio of the cost of the basket of goods in the current year to the cost in the base year. Cost of living in 2015 is 25% higher than in 2010. Cpi for the base year is always 1. Cpi for a given period is the cost of living in that period relative to what it was in the base year. Bea uses cpi as a percentage - the ratio times 100.
