This site, provided by Rob Grunewald of the Federal Reserve Bank of Minneapolis, is powerful but easy to use and learn from. Users enter a year between 1913 and 1997, a dollar amount purchased, and another year. Based on all major expenditure classes of the Consumer Price Index, the machine calculates the dollar value for that year. An explanation of how the index is used to answer this type of question is included. This informative site is not just for economics students.
