How to calculate the inflation rate for electricity, 1938-2021

Start with the inflation rate formula:

CPI in 2021 / CPI in 1938 * 1938 USD value = 2021 USD value

Then plug in historical CPI values from above. The CPI for Electricity was 29.400 in the year 1938 and 217.669 in 2021:

217.669 / 29.400 * $100 = $740.37

Therefore, according to U.S. Bureau of Labor Statistics, $100 in 1938 has the same "purchasing power" as $740.37 in 2021 (in the CPI category of Electricity).
