Sociology 441: Stratification

Consumer Price Index (CPI)

To convert current dollars to constant dollars, divide the current dollar amount by the consumer price index (CPI) below. For example, if you had an amount for 1960 that was $500 in current 1960 dollars, to adjust for inflation, divide that by the 1960 CPI (.296) to get $1689. This compares to $500 dollars in 1999 which in constant dollars is $300 ($500 / 1.666 = $300).
