Between 1930 and 1977, the Consumer Price Index went from 16.7 to 60.6.
Cumulatively, prices increased 262.9%, which works out to an average of
2.78% per year. Put differently, a dollar in 1930 bought what
$0.28 buys in 1977.
Consumer prices fell 2.3% in 1930, a mild decline compared with what was
coming but the first sign that the summer 1929 downturn was not going to be
short. The National Bureau of Economic Research dates that contraction from
August 1929, and by the time it finally bottomed out in March 1933 it would
run 43 months, the longest of any downturn in the NBER’s chronology back to
1854. Congress made the trade picture worse in June, when President Hoover
signed the Smoot-Hawley Tariff Act, raising duties on more than 20,000
imported goods to some of the highest levels in a century. Trading partners
retaliated with tariffs of their own, and global trade volumes collapsed
over the next several years, deepening a downturn economists still debate
how much the tariff itself worsened. The financial system cracked that fall:
a regional banking panic culminated in the December 11 failure of the Bank
of United States in New York, at the time the largest bank failure in
American history, wiping out more than $200 million in deposits. It was the
first of four banking panics that would hit the country before 1933 was
out. Consumer prices still stood 68.7% above their 1913
starting point, but the direction had clearly turned. First-class postage
held at 2 cents, unchanged for eleven straight years.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1930 spending costs in 1977, by category:

Not shown because the BLS began these indexes after 1930: 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.
