Adjust gas prices for inflation

Start with the inflation rate formula:

CPI in 2026 / CPI in 1966* 1966 USD value = 2026 USD value

Then plug in historical CPI values from above. The CPI for Gasoline (all types) was 25.542 in the year 1966 and 334.824 in 2026:

334.824 / 25.542* $4.20 = $55.06

Therefore, according to U.S. Bureau of Labor Statistics, $4.20 in 1966 has the same "purchasing power" as $55.06 in 2026 (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.
