How this is calculated
Value today = amount × (latest CPI-U ÷ 1977 average CPI-U). For $100: 100 × (334.980 ÷ 60.6) = $552.77. The average annual rate is the compound rate that turns 1977 prices into today’s over the elapsed time, measured from mid-1977 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 $18.09 in 1977.
