Between 1920 and 1976, the Consumer Price Index went from 20 to 56.9.
Cumulatively, prices increased 184.5%, which works out to an average of
1.88% per year. Put differently, a dollar in 1920 bought what
$0.35 buys in 1976.
1920 was the last year of the inflation that had built since the war began:
consumer prices rose 15.6% for the year, leaving the CPI more than double its
1913 starting level after seven straight years of increases.
The boom behind those increases turned to bust before the year was over. The
Federal Reserve, worried about speculation, pushed its discount rate to a
record 7% that spring, and wholesale prices, which had led the wartime
runup, began collapsing within months. The National Bureau of Economic
Research dates the resulting downturn from January 1920 to July 1921, one of
the shortest but steepest contractions in U.S. history, and consumer prices
followed into outright decline, falling 10.5% in 1921. Two constitutional
changes reshaped the country that year, too. The 18th Amendment’s ban on
alcohol took legal effect January 17, enforced under the Volstead Act
Congress had passed the previous October. Then, on August 18, Tennessee’s
ratification of the 19th Amendment secured women’s right to vote nationwide,
and women cast ballots in a presidential election for the first time that
November, when Warren Harding won on a promise to return the country to
“normalcy” after a decade of war, pandemic, and rising prices. First-class
postage held at 2 cents, unchanged since mid-1919.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1920 spending costs in 1976, by category:

Not shown because the BLS began these indexes after 1920: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1976
Consumer prices rose 5.8% in 1976, the calmest pace since 1972,
as the economy pulled out of the 1973-75 recession and price growth settled
to roughly half its 1974 peak. The recovery gave Americans
room to celebrate: tall ships filled New York Harbor and fireworks lit cities
nationwide on July 4 for the country’s bicentennial, a rare moment of shared
celebration after Vietnam and Watergate. Politically, Jimmy Carter, a former
Georgia governor running as a Washington outsider, defeated incumbent Gerald
Ford that November, campaigning on restoring trust in government and bringing
down inflation and unemployment together. In a California garage, Steve
Jobs, Steve Wozniak, and Ronald Wayne founded Apple Computer that April to
sell the Apple I, a bare circuit board aimed at electronics hobbyists, a
business that looked far from consequential at the time. First-class
postage, which had risen to 13 cents that past December 31, held there
through the year, the longest stretch without a rate change since the Postal
Service’s creation. A median household earned $12,686 in 1976, a new home
sold for a median $44,200, and gas averaged 59 cents a gallon. Consumer
prices stood 474.7% above their 1913 level, a calm interlude
before inflation turned back up.
