How to calculate the inflation rate for gas, 2000-2018

Start with the inflation rate formula:

CPI in 2018 / CPI in 2000 * 2000 USD value = 2018 USD value

Then plug in historical CPI values from above. The CPI for Gasoline (all types) was 128.600 in the year 2000 and 238.340 in 2018:

238.340 / 128.600 * $20 = $37.07
