How to calculate the inflation rate since 2011

Start with the CPI inflation formula:

CPI in 2017 / CPI in 2011 * 2011 USD value = 2017 USD value

Then plug in historical CPI values. The U.S. CPI was 224.939 in the year 2011 and 244.524 in 2017:

244.524 / 224.939 * $100 = $108.71

The "purchasing power" of $100 from 2011 is $108.71 in 2017.
