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 2021 CPI to the 1990 CPI.
factor = CPI(2021) / CPI(1990) = 2.0735
annual = factor^(1/31) − 1 = 0.0238 (2.38%)
annual = factor^(1/31) − 1 = 0.0238 (2.38%)
