Between 1929 and 1974, the Consumer Price Index went from 17.1 to 49.3.
Cumulatively, prices increased 188.3%, which works out to an average of
2.38% per year. Put differently, a dollar in 1929 bought what
$0.35 buys in 1974.
Consumer prices were unchanged in 1929, the CPI’s annual average flat for
the second time in six years and a fitting close to a decade that began with
wartime inflation and ended in rough price stability. By year’s end the
index stood 14.5% below its 1920 peak and roughly 73% above its
1913 starting point, a reminder that even a “stable” decade
left prices well above where they had started. The stability in the cost of
living masked what was building in financial markets. The National Bureau
of Economic Research dates the start of the Great Depression to that
August, the month the business cycle peaked, months before most Americans
noticed anything was wrong. The break came that October: panic selling hit
Wall Street on Black Thursday, October 24, and returned even worse on Black
Tuesday, October 29, when the Dow Jones Industrial Average fell about 12% in
a single session. Billions of dollars in paper wealth disappeared within
days, and the crash marked the start of a downturn that would pull consumer
prices into their steepest sustained decline of the 20th century over the
next four years. First-class postage was still 2 cents, a price that would
hold until 1932.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1929 spending costs in 1974, by category:

Not shown because the BLS began these indexes after 1929: 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: 1974
1974 was the year the postwar economy broke its old rules. Consumer prices
rose 11.0%, the fastest annual increase since 1947, as the Arab oil embargo
that ran from October 1973 to March 1974 roughly quadrupled the price of
crude oil worldwide. Gasoline, which had averaged 38.5 cents a gallon in
1973, jumped to 53.2 cents, and shortages forced many states into odd-even
rationing at the pump. Nixon’s wage and price controls, in place in some form
since 1971, expired at the end of April, removing the last brake on prices
just as the oil shock hit. Nixon himself resigned in August over Watergate,
and Gerald Ford’s response to inflation, a voluntary “Whip Inflation Now”
campaign built around lapel buttons, became a symbol of how little
conventional politics could do against the problem. Prices kept climbing even
as the economy weakened: a recession that started in November 1973 dragged
on, the Dow fell to a bear-market bottom of 577.60 in December, and
unemployment was already rising toward the 9% it would reach in 1975. The
combination of rising prices and a shrinking economy gave the decade its
name: stagflation.
