Between 1917 and 1977, the Consumer Price Index went from 12.8 to 60.6.
Cumulatively, prices increased 373.4%, which works out to an average of
2.63% per year. Put differently, a dollar in 1917 bought what
$0.21 buys in 1977.
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 1977, 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: 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.
