Inflation Rate Formula

To compute inflation, start with the inflation rate formula:

CPI in Y2 CPI in Y1 * Y1 USD value = Y2 USD value

For example, if you wanted to convert dollar amounts in the year 2000 to dollar amounts in the year 2018:

CPI in 2018 CPI in 2000 * 2000 USD value = 2018 USD value

Next, we plug in historical CPI values. The U.S. CPI was 172.2 in the year 2000 and 248.991 in early 2018:

248.991172.2 * $100 = $144.59

Therefore, $100 in 2000 has the same "purchasing power" as $144.59 in 2018.
