Between 1917 and 1955, the Consumer Price Index went from 12.8 to 26.8.
Cumulatively, prices increased 109.4%, which works out to an average of
1.96% per year. Put differently, a dollar in 1917 bought what
$0.48 buys in 1955.
1917 is when World War I inflation stopped being a background trend and
became the dominant fact of American economic life. Consumer prices rose
17.4% for the year, more than double the previous year’s already sharp
increase, as the country’s April 6 entry into the war layered federal war
spending on top of an economy already strained by military demand and
worker shortages. Congress paid for the war with the War Revenue Act that
October, which sharply raised income taxes, created a new tax on wartime
business profits, and, in a small but very visible change for ordinary
households, raised the cost of a first-class stamp from 2 cents to 3 cents
that November, the rate’s first move since 1885. Herbert Hoover took over
the new Food Administration in August and asked Americans to conserve food
voluntarily rather than face formal rationing, a campaign that became
famous enough that “Hooverize” entered the language as a verb for cutting
back. None of it slowed prices much: the 17.4% increase would be topped
again the very next year, in 1918.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1917 spending costs in 1955, by category:

Not shown because the BLS began these indexes after 1917: 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: 1955
Consumer prices fell 0.4% in 1955, the first annual decline since 1949,
as a strong rebound from the 1953-54 recession delivered growth without
much price pressure; automakers and appliance makers competed hard on
price for a booming consumer market. Organized labor consolidated that
December, when the American Federation of Labor and the Congress of
Industrial Organizations merged on the 5th under President George Meany,
uniting roughly 15 million workers in the AFL-CIO after two decades as
rival federations. That same day, a different kind of organizing began in
Montgomery, Alabama: four days after Rosa Parks was arrested for refusing
to give up her bus seat to a white passenger, the city’s Black community
began a boycott of its buses that would last more than a year and help
launch the civil rights movement’s mass phase. Markets got a scare that
September: news of Eisenhower’s heart attack on the 24th sent the Dow
Jones Industrial Average to its steepest one-day drop since the 1929
crash when trading resumed that Monday, before stocks recovered as the
president’s health improved. Consumer prices finished 1955 170.7% above
their 1913 level, essentially unchanged from where they
stood a year earlier. First-class postage held at 3 cents, and the
minimum wage stayed at 75 cents an hour.
