How to calculate the inflation rate for gas, 1935-2021

Start with the inflation rate formula:

CPI in 2021 / CPI in 1935 * 1935 USD value = 2021 USD value

Then plug in historical CPI values from above. The CPI for Gasoline (all types) was 13.150 in the year 1935 and 243.583 in 2021:

243.583 / 13.150 * $20 = $370.47

Therefore, according to U.S. Bureau of Labor Statistics, $20 in 1935 has the same "purchasing power" as $370.47 in 2021 (in the CPI category of Gasoline (all types)).

Source: U.S. Bureau of Labor Statistics began tracking the Consumer Price Index for Gasoline (all types) in 1935. In addition to gas, the index produces monthly data on changes in prices paid by urban consumers for a variety of goods and services.
