Inflation conversion factor tables for 2016 have been revised to reflect final 2016 CPI (2.40007) and estimates of inflation for 2017 through 2027, based on the average of inflation estimates by the Office of Management and Budget (OMB) and the Congressional Budget Office (CBO).  These pages were revised June 15 and June 19, 2017.

Inflation assumptions:   These are stated on the main conversion factor page.

Conversion factor tables are available as Portable Document Format (pdf) files and also in Excel format, for direct use in conversion.  The tables of conversion factors directly below cover the period 1774 to estimated 2027.

Following are the files of conversion factors for each year.  Only the tables for 2016 and estimated 2017 have been updated in 2017 to reflect final 2016 CPI.  For other years, use the file (Excel and pdf) that provides conversion factors for all years, available from the main page.

  •   Conversion Factors in 2016 Dollars for 1774 to estimated 2027     pdf             Excel
  •  Conversion Factors in estimated 2017 Dollars for 1774 to estimated 2027.  Reminder:  These are estimates and will be changed with final data in 20918.  Suggest using (final) 2016 conversion factors unless 2017 estimates are essential.                                  pdf           Excel
  • Conversion Factors in two special measures of inflation, the CPI-U-X1 and the CPI-U-RS, both in dollars of 2016.  The CPI-U-X1 applies the post-1983 CPI to the entire period starting in 1950, for comparability during that entire period.  By definition, the CPI-U and CPI-U-X1 is the same after 1983.  The CPI-U-RS is “Research Series,” with 1977 = 100, extended to 1947 by the Census Bureau), re-based here to 2016 = 1.000.  Note that unlike other CPI measures, the CPI-U-RS data can be revised each year for earlier years, not just for the most recent year.  For that reason, no estimated CPI-U-RS conversion factors are supplied for any year after 2016. The files contain links to additional sources of information from the Bureau of Labor Statistics, especially concerning the CPI-U-RS.    pdf              Excel

Original data for the CPI-U-RS are available from the Bureau of Labor Statistics

ReminderConversion factors for years prior to 1913 should be considered to be estimates. In addition, CPI measures have changed over time, so data for the entire period are not precisely comparable. Note that conversion factors that apply the post-1982 CPI to the period 1950 to 1982 are available above as the CPI-U-X1, in 2013 dollars.

From the main Bureau of Labor Statistics CPI page, many data are available, including a complete table of monthly CPI-U data with semi-annual and annual changes from 1913 to the present.
