What happened to prices between 1915 and 2025
Between 1915 and 2025, the Consumer Price Index went from 10.1 to 321.943.
Cumulatively, prices increased 3087.6%, which works out to an average of
3.20% per year. Put differently, a dollar in 1915 bought what
$0.03 buys in 2025: the 1915 dollar
lost 96.9% of its purchasing power over
these 110 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 2025 at the same ratio, 31.88: $1,000 becomes
$31,876, and $10,000 becomes $318,755.

Year by year: CPI and the value of $100 from 1915
$100 from 1915 had already become $384 by
1970, on its way to $3,188 in 2025; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 18.0% in 1918, and prices fell 10.5% in 1921, the deepest deflation of the period.
Long periods are sampled every 5 years; the calculator above covers any pair of years.
The destination year: 2025
In 2025, prices rose 2.6% and $100 from 1915 had the buying
power of $3,188; the year's average CPI of 321.943 is the level
behind every 2025 figure on this page.
2025 was a year of trade policy and data disruptions rather than an
inflation surge. Consumer prices rose 2.6% on average, a step down from
2024’s 2.9% and well below the 8.0% of 2022. Tariffs announced in April
pushed up prices for some imported goods, including furniture, apparel, and
auto parts, but the effect on the overall index was smaller than many
forecasters feared at the start of the year, in part because retailers
absorbed some of the cost and demand for services stayed steady.
The Federal Reserve held its policy rate steady through the first half of the
year, then began cutting again in September, lowering it in three quarter-point
steps to 3.50–3.75% by December.
The federal government shutdown that began October 1 lasted 43 days, and the
Bureau of Labor Statistics did not publish a CPI for October 2025 because the
survey data could not be collected. The federal minimum wage stayed at $7.25,
and a first-class stamp rose to 78 cents in July.
