What happened to prices between 1915 and 2026
Between 1915 and 2026, the Consumer Price Index went from 10.1 to 332.243.
Cumulatively, prices increased 3189.5%, which works out to an average of
3.20% per year. Put differently, a dollar in 1915 bought what
$0.03 buys in 2026: the 1915 dollar
lost 97.0% of its purchasing power over
these 111 years.
Consumer prices rose 1.0% in 1915, the second straight year of near-flat
inflation before the wartime price surges of 1916 through 1918. The year’s
defining event had nothing to do with prices directly: a German submarine
sank the British liner Lusitania off the Irish coast on May 7, killing 128
Americans and hardening U.S. opinion against Germany two years before the
country entered the war. Economically, 1915 was a turning point of a
different kind. A recession that had dragged on since 1913 began lifting as
Britain and France placed growing orders for steel, munitions, and other war
materiel with American manufacturers, and U.S. exports to the Allied powers
climbed sharply through the year. That demand would keep building through
1916, eventually pulling prices up with it. On the regulatory
side, the Federal Trade Commission opened for business in March, taking on
enforcement of the Clayton Antitrust Act that Congress had passed the
previous fall. A first-class stamp still cost 2 cents, unchanged since 1885
and still two years from its first wartime increase.
Every 1915 amount converts to 2026 at the same ratio, 32.90: $1,000 becomes
$32,895, and $10,000 becomes $328,953.
