Between 1921 and 1977, the Consumer Price Index went from 17.9 to 60.6.
Cumulatively, prices increased 238.5%, which works out to an average of
2.20% per year. Put differently, a dollar in 1921 bought what
$0.30 buys in 1977.
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 1977, 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: 1977
Consumer prices rose 6.5% in 1977, ticking back up from 1976’s
5.8% as the economic recovery strengthened, wages climbed, and energy costs
pushed higher again. The year opened with a warning about that energy
dependence: record cold across the Midwest and Northeast in January and
February strained natural gas supplies so badly that schools and factories in
several states shut down for days to conserve fuel. Jimmy Carter, inaugurated
that January, made energy policy a centerpiece of his presidency, and
Congress created the cabinet-level Department of Energy that August to
consolidate programs built up piecemeal since the 1973 oil embargo. Culture
offered some relief from the anxiety: released that May, Star Wars became the
highest-grossing film in history to that point, drawing lines around theater
blocks for months. The year also closed an era in a different way. Elvis
Presley was found dead at his Graceland home on August 16 at age 42, drawing
tens of thousands of mourners to Memphis. A median household earned $13,572
in 1977, a new home sold for a median $48,800, and gas averaged 62 cents a
gallon. Consumer prices stood 512.1% above their 1913 level,
with the energy anxieties of the year setting up the harder shocks of 1978
and 1979.
