DEFINITION of 'Consumer Price Index-CPI'. A measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food and medical care. The CPI is calculated by taking price changes for each item in the predetermined basket of goods and averaging them; the goods are weighted according to their importance.
It lists all the Consumer Price Index (CPI-U) numbers from January 2000 to the Present. The Consumer Price Index (CPI-U) is compiled by the Bureau of Labor Statistics and is based upon a 1982 Base of 100. Therefore, a Consumer Price Index of 158 would indicate 58% inflation since 1982. The commonly quoted inflation rate of say 3% is actually the change in the Consumer Price Index from a year earlier. By looking at the change in the index we can see that what cost an average of 9.9 cents in 1913 would cost about $1.82 in 2003 and $2.30 in August of 2012.
