Between 1916 and 1931, the Consumer Price Index went from 10.9 to 15.2.
Cumulatively, prices increased 39.4%, which works out to an average of
2.24% per year. Put differently, a dollar in 1916 bought what
$0.72 buys in 1931.
1916 was when World War I first showed up clearly in American price tags.
Consumer prices rose 7.9% for the year, easily the sharpest increase since
the Bureau of Labor Statistics’ CPI history begins in 1913, as factories ran
flat out to fill steel, munitions, and food orders from Britain and France.
Railroad workers felt the squeeze from rising living costs enough to threaten
a nationwide strike; Congress headed it off in September with the Adamson
Act, which set an eight-hour standard workday for interstate rail employees,
the first federal law of its kind covering private-sector hours. Washington
was also preparing more directly for war: the National Defense Act, signed
in June, expanded the Army and National Guard and funded new
government-owned munitions plants, adding another source of demand to an
economy already running hot. Woodrow Wilson won re-election in November
largely on having kept the country out of the fighting so far, a promise
that would not survive the following spring. A first-class stamp still cost
2 cents, one of the few prices that had not yet moved.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1916 spending costs in 1931, by category:

Not shown because the BLS began these indexes after 1916: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices fell 9.0% in 1931, a sharp acceleration from the 2.3% decline
in 1930, as falling wages, collapsing farm prices, and a fresh
wave of bank failures fed a downward spiral that the still-contracting
economy could not shake. More than 2,000 banks failed during the year, far
more than in 1930, as depositors who had watched earlier banks go under
pulled their cash out of ones they feared were next. The crisis went
international that September, when Britain suspended the gold standard amid
a run on sterling. The Federal Reserve’s response made the domestic downturn
worse before it made anything better: to defend the dollar’s own gold
backing, the Fed raised its discount rate sharply that October, in two steps
from 1.5% to 3.5%, tightening credit at the exact moment the economy needed
the opposite. Not every headline that year was grim. The Empire State
Building opened its doors on May 1, briefly the tallest building in the
world, though so much of Manhattan’s office space sat vacant amid the
Depression that tenants stayed scarce and New Yorkers took to calling it the
“Empty State Building.” Consumer prices had now fallen for two straight
years and stood 53.5% above their 1913 level, down from the
68.7% margin of just twelve months before. First-class postage remained at 2
cents.
