How this is calculated
Value today = amount × (latest CPI-U ÷ 1975 average CPI-U). For $100: 100 × (334.980 ÷ 53.8) = $622.64. The average annual rate is the compound rate that turns 1975 prices into today’s over the elapsed time, measured from mid-1975 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 $16.06 in 1975.
