What happened to prices between 1931 and 2025
Between 1931 and 2025, the Consumer Price Index went from 15.2 to 321.943.
Cumulatively, prices increased 2018.0%, which works out to an average of
3.30% per year. Put differently, a dollar in 1931 bought what
$0.05 buys in 2025: the 1931 dollar
lost 95.3% of its purchasing power over
these 94 years.
Consumer prices fell 9.0% in 1931, a sharp acceleration from the 2.3% decline
in 1930, as falling wages, collapsing farm prices, and a fresh
wave of bank failures fed a downward spiral that the still-contracting
economy could not shake. More than 2,000 banks failed during the year, far
more than in 1930, as depositors who had watched earlier banks go under
pulled their cash out of ones they feared were next. The crisis went
international that September, when Britain suspended the gold standard amid
a run on sterling. The Federal Reserve’s response made the domestic downturn
worse before it made anything better: to defend the dollar’s own gold
backing, the Fed raised its discount rate sharply that October, in two steps
from 1.5% to 3.5%, tightening credit at the exact moment the economy needed
the opposite. Not every headline that year was grim. The Empire State
Building opened its doors on May 1, briefly the tallest building in the
world, though so much of Manhattan’s office space sat vacant amid the
Depression that tenants stayed scarce and New Yorkers took to calling it the
“Empty State Building.” Consumer prices had now fallen for two straight
years and stood 53.5% above their 1913 level, down from the
68.7% margin of just twelve months before. First-class postage remained at 2
cents.
Every 1931 amount converts to 2025 at the same ratio, 21.18: $1,000 becomes
$21,180, and $10,000 becomes $211,805.

Year by year: CPI and the value of $100 from 1931
$100 from 1931 had already become $374 by
1976, on its way to $2,118 in 2025; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 14.4% in 1947, and prices fell 9.9% in 1932, 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 1931 had the buying
power of $2,118; 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.
