### How to calculate the inflation rate for \$100 since 1955

This inflation calculator uses the following inflation rate formula:

CPI in 2018 / CPI in 1955 * 1955 USD value = 2018 USD value

Then plug in historical CPI values. The U.S. CPI was 26.8 in the year 1955 and 251.59 in 2018:

251.59 / 26.8 * \$100 = \$938.77
