How to calculate the inflation rate for electricity, 1978-2021

Start with the inflation rate formula:

CPI in 2021 / CPI in 1978 * 1978 USD value = 2021 USD value

Then plug in historical CPI values from above. The CPI for Electricity was 60.838 in the year 1978 and 217.669 in 2021:

217.669 / 60.838 * $100 = $357.78

Therefore, according to U.S. Bureau of Labor Statistics, $100 in 1978 has the same "purchasing power" as $357.78 in 2021 (in the CPI category of Electricity).
