Converting Past Dollars into Present Dollars

Look up both years you want to do the conversion on in the table above, and then use the following formula:

Amount * (NewestYearCPI / OldestYearCPI) = ConvertedAmount

EXAMPLE: The M4 Sherman medium tank cost the U.S. Government $42,400 during Fiscal Year 1943. How much would this be in 2010?

2010 CPI-U: 218.056
1943 CPI-U: 17.300

42,400 * (218.056 / 17.300) = $534,426.265

Gives us a 2010 cost of around $534,426.27 dollars.

Converting Present Dollars into Past Dollars

Look up both years you want to do the conversion on in the table above, and then use the following formula:

Amount * (OldestYearCPI / NewestYearCPI) = ConvertedAmount

EXAMPLE: The M1A2 Abrams SEP v2 Main Battle Tank costs the U.S. Government around $4,300,000 per tank in 2007. We want to convert this to 1943 dollars, to see how it stacks up against the M4 Sherman.

2007 CPI-U: 207.342
1943 CPI-U: 17.300

4,300,000 * (17.300 / 207.342) = $358,779.215

Gives us a 1943 cost of $358,779.22 dollars.
