Between 1918 and 1942, the Consumer Price Index went from 15.1 to 16.3.
Cumulatively, prices increased 7.9%, which works out to an average of
0.32% per year. Put differently, a dollar in 1918 bought what
$0.93 buys in 1942.
1918 brought the steepest annual price increase the CPI had recorded:
consumer prices rose 18.0% for the year, edging out 1917’s already sharp
17.4% as the economy stayed at full wartime mobilization for most of the
year. A first-class stamp cost 3 cents, up from 2 cents the previous
November under the War Revenue Act’s wartime tax increases. The war itself
ended on November 11, when Germany signed an armistice with the Allied
powers after more than four years of fighting in Europe, but the inflation
built up over a year and a half of mobilization did not disappear along with
the fighting. The bigger public health story that year was the influenza
pandemic that reached the U.S. in a mild spring wave and then returned that
fall in a far deadlier form, eventually killing roughly 675,000 Americans,
more than the country’s combat losses in the war. It hit factories, docks,
and shops alongside households, adding disruption to an economy already
strained by wartime demand. Prices would keep climbing even after the
armistice, into the postwar surge of 1919.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1918 spending costs in 1942, by category:

Not shown because the BLS began these indexes after 1918: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Consumer prices rose 10.9% in 1942, up from 1941’s already
rapid 5.0% and the fastest increase since 1920, as the economy’s crash
conversion to war production collided with shrinking supplies of civilian
goods. The government tried to contain it: the General Maximum Price
Regulation, effective May 18 and known as “General Max,” froze most retail
prices at their highest March level, the broadest price control Washington
had ever attempted. Rationing followed close behind. Sugar rationing began
that May and gasoline rationing went nationwide in December, the leading
edge of a system that would eventually cover meat, coffee, shoes, tires, and
dozens of other goods before the war ended. The year’s other defining
wartime measure had nothing to do with prices. Executive Order 9066, signed
February 19, authorized the military to remove more than 110,000 Japanese
Americans, most of them U.S. citizens, from the West Coast and hold them in
inland internment camps for the war’s duration, one of the era’s starkest
violations of civil liberties. Even with price controls in place, consumer
prices climbed more than 10% for the first time since 1920, leaving the CPI
64.6% above its 1913 level. First-class postage held at 3
cents, and the minimum wage stayed at 30 cents an hour.
