Between 1919 and 1981, the Consumer Price Index went from 17.3 to 90.9.
Cumulatively, prices increased 425.4%, which works out to an average of
2.71% per year. Put differently, a dollar in 1919 bought what
$0.19 buys in 1981.
The fighting in Europe ended in November 1918, but American prices kept
climbing through 1919 almost as fast as they had during the war itself,
rising 14.6% for the year. Wartime price and production controls were being
dismantled, millions of soldiers were returning to the civilian labor
market, and demand that had been held back for years ran into supply that
had not caught up, a combination that kept the cost of living rising even
with the guns silent. Workers, whose pay had fallen behind three straight
years of double-digit inflation, pushed back: a general strike shut down
Seattle in February, Boston’s police force walked out in September, and a
nationwide steel strike that same month drew in roughly 350,000 workers and
ran into the following January. One price did fall that year: first-class
postage reverted to 2 cents on July 1, ending the wartime 3-cent rate that
had funded part of the war effort since late 1917. By year’s end, prices had
risen close to 75% since the CPI’s 1913 starting point,
compressing more than a decade of typical peacetime inflation into six years
of war and its aftermath.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1919 spending costs in 1981, by category:
Category
Avg. yearly inflation
$100 in 1919 →
All items (CPI-U)
2.71%
$525
Food
2.64%
$503
Apparel
1.57%

Not shown because the BLS began these indexes after 1919: 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 5 years; the calculator above covers any pair of years.
The destination year: 1981
1981 was the year the inflation fever finally broke, at an extraordinary price.
Consumer prices rose 10.3%, the second year of back-to-back double-digit
inflation and the last time the U.S. would see one. To end it, Paul Volcker’s
Federal Reserve drove its policy rate above 19% and let borrowing costs go
where they may: a 30-year mortgage cost more than 18% by autumn, car loans and
business credit froze, and homebuilders mailed the Fed two-by-fours in protest.
The squeeze tipped the economy into recession in July, the deep 1981–82
downturn that would push unemployment past 10%. But it worked. Inflation fell
by nearly half within a year and to under 4% by 1983, the disinflation that
defined the following two decades. Even the price of mailing a letter told the
year’s story: postage went up twice in eight months.
