Between 1956 and 1990, the Consumer Price Index went from 27.2 to 130.7.
Cumulatively, prices increased 380.5%, which works out to an average of
4.72% per year. Put differently, a dollar in 1956 bought what
$0.21 buys in 1990.
Consumer prices rose 1.5% in 1956, a return to mild inflation after they had
fallen 0.4% in 1955, the only annual decline of the decade. The two years sat
in the calmest stretch of the postwar index, a lull between the Korean War
price surge earlier in the 1950s and the acceleration that would return in
the 1970s. Congress had already raised the wage floor into that calm: the
Fair Labor Standards Amendments of 1955, signed the previous August, took
effect March 1 and lifted the federal minimum wage from 75 cents to $1 an
hour, the first increase since 1950. Eisenhower signed a longer-lasting
commitment on June 29, the Federal-Aid Highway Act, funding 41,000 miles of
controlled-access highway at 90% federal cost to build the Interstate
System, the largest public-works program the country had undertaken. He won
a second term that November, carrying 41 states and about 57% of the
popular vote in a rematch against Adlai Stevenson. Abroad, the Suez Crisis
broke the calm on the supply side: Egypt nationalized the canal on July 26,
and after Israel invaded the Sinai on October 29 with British and French
forces following, the canal’s closure and damaged pipelines squeezed oil
shipments to Western Europe for months. Consumer prices stood 174.7% above
their 1913 level by 1956, up 94% since 1940
alone, even after a decade that had barely moved the index. First-class
postage held at 3 cents, unchanged since 1932.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1956 spending costs in 1990, by category:

Not shown because the BLS began these indexes after 1956: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), recreation (1993–), education & communication (1993–).
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1990
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
