What happened to prices between 1948 and 1999
Between 1948 and 1999, the Consumer Price Index went from 24.1 to 166.6.
Cumulatively, prices increased 591.3%, which works out to an average of
3.86% per year. Put differently, a dollar in 1948 bought what
$0.14 buys in 1999: the 1948 dollar
lost 85.5% of its purchasing power over
these 51 years.
Consumer prices rose 8.1% in 1948, down slightly from 1947’s
14.4% but still the second straight year of sharp postwar inflation now
that wartime price controls were fully gone. Congress moved to stabilize a
different economy that April, passing the Economic Cooperation Act to fund
the plan Secretary of State George Marshall had proposed the year before:
more than $13 billion over four years to rebuild Western Europe and counter
Soviet influence. The Cold War turned tense closer to the plan’s target
that June, when Soviet forces cut off road and rail access to the
Western-controlled sectors of Berlin. American and British aircraft
responded almost immediately with an airlift of food, fuel, and supplies
that would keep the city running for nearly a year. Domestic politics
produced its own upset that November: nearly every poll and pundit had
predicted a Republican win, but Harry Truman defeated New York Governor
Thomas Dewey, handing the Chicago Tribune its famously wrong “Dewey Defeats
Truman” headline. Consumer prices finished the year 143.4% above their
1913 level and 40.9% above 1929’s
pre-Depression peak. First-class postage held at 3 cents, and the minimum
wage stayed at 40 cents an hour.
Every 1948 amount converts to 1999 at the same ratio, 6.91: $1,000 becomes
$6,913, and $10,000 becomes $69,129.

Year by year: CPI and the value of $100 from 1948
$100 from 1948 had already become $205 by
1974, on its way to $691 in 1999; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 13.5% in 1980, and prices fell 1.2% in 1949, the deepest deflation of the period.
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1999
In 1999, prices rose 2.2% and $100 from 1948 had the buying
power of $691; the year's average CPI of 166.6 is the level
behind every 1999 figure on this page.
The median household earned about $40,700 in 1999, gas averaged $1.17 a gallon, and a new home
cost roughly $161,000. Inflation ran at 2.2% for the year, ticking back up from 1998’s decade low
as oil prices recovered from their collapse. The decade closed with two changes to the financial
system that would shape the one after it: on January 1, the euro launched as an accounting
currency across 11 European countries, trading alongside national currencies like the French
franc and German mark ahead of physical cash in 2002, and in November, Congress passed the
Gramm-Leach-Bliley Act, tearing down the Depression-era wall between commercial banks, investment
banks, and insurers. Stock markets, meanwhile, were absorbed in a boom of their own: the Nasdaq
surged through the year on soaring internet-stock valuations, and the Federal Reserve raised
interest rates three times in the second half of 1999 partly to cool the exuberance, even as it
pumped extra liquidity into the banking system to guard against any disruption from the Y2K
rollover. A first-class stamp cost 33 cents. Inflation had spent the decade falling from 1990’s
5.4% peak to averages closer to 2-3%, and 1999 closed it out almost exactly where the 1990s as a
whole had settled.
