What happened to prices between 1920 and 2026
Between 1920 and 2026, the Consumer Price Index went from 20 to 332.243.
Cumulatively, prices increased 1561.2%, which works out to an average of
2.69% per year. Put differently, a dollar in 1920 bought what
$0.06 buys in 2026: the 1920 dollar
lost 94.0% of its purchasing power over
these 106 years.
1920 was the last year of the inflation that had built since the war began:
consumer prices rose 15.6% for the year, leaving the CPI more than double its
1913 starting level after seven straight years of increases.
The boom behind those increases turned to bust before the year was over. The
Federal Reserve, worried about speculation, pushed its discount rate to a
record 7% that spring, and wholesale prices, which had led the wartime
runup, began collapsing within months. The National Bureau of Economic
Research dates the resulting downturn from January 1920 to July 1921, one of
the shortest but steepest contractions in U.S. history, and consumer prices
followed into outright decline, falling 10.5% in 1921. Two constitutional
changes reshaped the country that year, too. The 18th Amendment’s ban on
alcohol took legal effect January 17, enforced under the Volstead Act
Congress had passed the previous October. Then, on August 18, Tennessee’s
ratification of the 19th Amendment secured women’s right to vote nationwide,
and women cast ballots in a presidential election for the first time that
November, when Warren Harding won on a promise to return the country to
“normalcy” after a decade of war, pandemic, and rising prices. First-class
postage held at 2 cents, unchanged since mid-1919.
Every 1920 amount converts to 2026 at the same ratio, 16.61: $1,000 becomes
$16,612, and $10,000 becomes $166,122.
