About the Calculator
The Inflation Calculator uses monthly consumer price index (CPI) data from 1914 to the present to show changes in the cost of a fixed "basket" of consumer purchases. These include food, shelter, furniture, clothing, transportation, and recreation. An increase in this cost is called inflation.
The calculator's results are based on the most recent month for which the CPI data are available. This will normally be about two months prior to the current month.
