What happened to prices between 1939 and 2024
Between 1939 and 2024, the Consumer Price Index went from 13.9 to 313.689.
Cumulatively, prices increased 2156.8%, which works out to an average of
3.73% per year. Put differently, a dollar in 1939 bought what
$0.04 buys in 2024: the 1939 dollar
lost 95.6% of its purchasing power over
these 85 years.
Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI
fell in six years and rose in four, leaving prices 18.7% below their
1929 level even after the mid-decade recovery. Measured
against the start of the CPI’s modern record, prices still stood 40.4%
above their 1913 level, a reminder that even a decade defined
by deflation left the cost of living well above where it had been a
generation earlier. The decade’s final months reset the economic picture
entirely. Germany invaded Poland on September 1, and Britain and France
declared war two days later; the United States stayed formally neutral
under the Neutrality Acts, but Allied orders for war materiel began flowing
to American factories almost immediately, a demand shock that would do more
to end the Depression over the next few years than any peacetime relief
program had managed. Domestic policy kept building on the New Deal’s
framework, too: the federal minimum wage rose to 30 cents an hour that
October, the second step in the schedule set by the 1938 Fair Labor
Standards Act. Amid it all, the New York World’s Fair opened April 30 in
Queens, themed “The World of Tomorrow” and drawing tens of millions of
visitors with exhibits on television and other technologies promising a
more prosperous decade than the one just ending. First-class postage held
at 3 cents.
Every 1939 amount converts to 2024 at the same ratio, 22.57: $1,000 becomes
$22,568, and $10,000 becomes $225,676.

Year by year: CPI and the value of $100 from 1939
$100 from 1939 had already become $522 by
1979, on its way to $2,257 in 2024; 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 1.2% in 1949, the deepest deflation of the period.
Long periods are sampled every 5 years; the calculator above covers any pair of years.
The destination year: 2024
In 2024, prices rose 2.9% and $100 from 1939 had the buying
power of $2,257; the year's average CPI of 313.689 is the level
behind every 2024 figure on this page.
2024 brought inflation close to normal without fully reaching it. Consumer
prices rose 2.9% on average, the smallest yearly increase since 2020, and the
December-to-December rate was also 2.9%. Gasoline averaged $3.30 a gallon,
below 2023’s $3.52. Shelter stayed the biggest driver of the index, so the
pace of price growth in categories that households can’t easily avoid, such as
rent and insurance, lagged the drop in goods and energy costs.
The Federal Reserve declared progress in September, cutting its policy rate
by half a point, the first reduction since the pandemic emergency, and then
by a quarter point in November and again in December. Mortgage rates near 7%
kept the housing market frozen for many would-be buyers.
Median household income was $83,730, the federal minimum wage stayed at $7.25,
and a first-class stamp rose to 73 cents in July. After the November election,
attention turned to how announced tariffs and tax policy might affect prices
in 2025.
