How to calculate the inflation rate for dairy and related products, 1940-2021

Start with the inflation rate formula:

CPI in 2021 / CPI in 1940 * 1940 USD value = 2021 USD value

Then plug in historical CPI values from above. The CPI for Dairy and related products was 15.946 in the year 1940 and 230.325 in 2021:

230.325 / 15.946 * $20 = $288.88

Therefore, according to U.S. Bureau of Labor Statistics, $20 in 1940 has the same "purchasing power" as $288.88 in 2021 (in the CPI category of Dairy and related products).
