A dollar from 1980 is worth $4.09 in September 2026, using the CPI-U for the U.S. city average: the 1980 annual average of 82.4 against 336.94 now, a rise of 309 % or 3.09 % a year. Put the other way, today's dollar buys what $0.24 bought in 1980. The year itself is the high point of the national annual series since 1947: prices rose 13.5 % over 1979, and no year since has been as high. The slowdown came fast. Annual inflation fell to 10.3 % in 1981, 6.2 % in 1982, 3.2 % in 1983. By 1990 a 1980 dollar needed $1.59. In 1980 every one of the four regions and 20 metro indexes were already published, so a local 1980 amount can usually be carried on its own area.
The top of the curve
On annual averages, 1980 is the fastest year of the national CPI-U since 1947. Prices had risen 7.6 % in 1978 and 11.3 % in 1979 before the 13.5 % of 1980. Measured December to December, the 1980 rate was 12.5 %, lower than the change in the annual average.
A $1,000 amount of 1980 matches $4,089 today. If it was a fixed pension or a rent frozen since then, it has lost 76 % of its buying power.

1980 across the country
The local map was already wide in 1980. All four regions had a 1980 annual average, ranging from 12.9 % in the Northeast to 14.7 % in the West. Among the 20 metros with a 1980 figure, Dallas-Fort Worth ran fastest at 16.9 % and Urban Alaska slowest at 10.2 %. The size class indexes did not exist yet; they begin in December 1986 and December 1996.
Why 1982-84 equals 100
The index level of 1980, 82.4, is below 100 because the reference base of most CPI series is the average of 1982, 1983 and 1984. The national annual averages for those three years were 96.5, 99.6, 103.9. A base is only a scale: it changes index levels, never the percent change between two dates.
1980 next to the 2022 surge
If you compare the recent surge with 1980, the data let you measure the gap. On a 12-month basis the national CPI-U peaked at 14.8 % in March 1980; the recent peak was 9.1 % in June 2022. On annual averages, 1980 ran at 13.5 % and 2022 at 8.0 %. Annual inflation topped 10 % in 1974, 1979, 1980 and 1981; no year of the recent surge did.
The decade after
From the 1980 average to the 1990 average, prices rose 58.6 %, or 4.72 % a year, compared with 7.82 % a year over the 1970s. The inflation rate by year page lists each of those years for any area.
