Consumer Price Index (CPI) Conversion Factors 1774 to estimated 2019 to Convert to Estimated Dollars of 2009
Estimates for 2009-2019 are based on the average of OMB and CBO estimates as of early 2009.  They will be revised February 2010.
Recommendation:  Because these data are only ESTIMATES as of early 2009, use FINAL 2008 data unless 2009 (estimated) data are essential.
To convert dollars of any year to estimated dollars of the year 2009,  DIVIDE the dollar amount from that year by the conversion factor (CF) for that year.  For example, $1000 of 1922 = $12,658 of estimated 2008 ($1000 / 0.079).
To reverse the process, that is, to determine what an estimated 2009-dollar amount would be in dollars of another year, simply  multiply the year 2009 amount by the conversion factor for that year.  For example, $1000 of 2008 would be about $65 in 1940 ($1000 x 0.065 = $65).
Data series since 1912 have changed periodically, so numbers are not all precisely comparable.  Therefore it is recommended that numbers be ROUNDED to no more than three decimal places. For example, $12,658 in the example above becomes $12,660.  For years prior to 1913, rounding to two decimal places is recommended, e.g. $12,658 becomes $12,700.

Revised June 3, 2009, using final 2008 CPI (CPI = 2.15303) and OMB and CBO Spring 2009 inflation estimates for 2009-2019.  For inflation assumptions for 2009 and later years, see the shaded box below.
CPI is CPI-U, the broader measure for all urban consumers, year-to-year average (not December to December).
Conversion factors for years before 1913 are re-based from data from the Historical Statistics of the United States Millennial Edition (Cambridge University Press, 2006). Calculation starting 1913 uses the CPI-U as the base, from the US Bureau of Labor Statistics. Monthly and annual CPI data are available at the BLS web site: http://stats.bls.gov/cpi/home.htm#data (CPI-U = all urban consumers).
Inflation assumptions:  Inflation conversion factors for 2009 and later years assume inflation of -0.65% in 2009, 1.50% in 2010 and 2011; 1.60% in 2012; and 1.65% each year 2013 to 2019.  These are the averages of OMB and CBO inflation estimates for each year as of March 2009.
CF denominated in years 1995 to estimated 2009 in Excel format starting 1774 are available at: http://oregonstate.edu/cla/polisci/faculty-research/sahr/infcf17742008.xls
CF denominated in years 1995 to estimated 2009 in pdf format starting 1774 are available at: http://oregonstate.edu/cla/polisci/faculty-research/sahr/infcf17742008.pdf
Prior to the 2008 revision, a different data base was used for the period starting 1665 and ending 1913.  See the main inflation conversion factor page for details.
