How this is calculated
Value today = amount × (latest CPI-U ÷ 1940 average CPI-U). For $100: 100 × (334.980 ÷ 14.0) = $2,392.71. The average annual rate is the compound rate that turns 1940 prices into today’s over the elapsed time, measured from mid-1940 because an annual average describes the middle of the year. CPI-U tracks a broad basket of urban consumer spending; the prices of specific items such as housing, tuition or food have moved by different amounts.
Reverse: $100.00 today had the same buying power as $4.18 in 1940.
