How this was calculated
Based on the US Bureau of Labor Statistics Consumer Price Index (CPI). The cumulative inflation factor is the ratio of the 2020 CPI to the 1980 CPI.
factor = CPI(2020) / CPI(1980) = 3.1408
annual = factor^(1/40) − 1 = 0.0290 (2.90%)
annual = factor^(1/40) − 1 = 0.0290 (2.90%)
