Between 1921 and 1976, the Consumer Price Index went from 17.9 to 56.9.
Cumulatively, prices increased 217.9%, which works out to an average of
2.12% per year. Put differently, a dollar in 1921 bought what
$0.31 buys in 1976.
Consumer prices fell 10.5% in 1921, the mirror image of the wartime
inflation that had more than doubled the cost of living between
1913 and 1920. The Depression of 1920-21, one
of the sharpest contractions in U.S. history, bottomed out that July
according to the National Bureau of Economic Research, even though it had
lasted barely eighteen months. Unemployment climbed toward one worker in ten
as businesses cut production and prices to work through wartime inventories,
but the same collapse in prices also meant the recovery, once it started,
had room to run without reigniting inflation. Warren Harding took office
March 4, promising a return to “normalcy” after a decade of war, pandemic,
labor unrest, and rapid price swings; his administration moved quickly to
cut top income tax rates and federal spending. Congress also acted on
immigration that year: the Emergency Quota Act, signed May 19, capped annual
arrivals from each country at 3% of that nationality’s population in the
1910 census, the first time the United States had set a numerical ceiling on
immigration. The law favored northern and western Europe and cut total
immigration by more than half compared with prewar levels; Congress
tightened the formula again in 1924. 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 1921 spending costs in 1976, by category:

Not shown because the BLS began these indexes after 1921: 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.
