What happened to prices between 1999 and 2024
Between 1999 and 2024, the Consumer Price Index went from 166.6 to 313.689.
Cumulatively, prices increased 88.3%, which works out to an average of
2.56% per year. Put differently, a dollar in 1999 bought what
$0.53 buys in 2024: the 1999 dollar
lost 46.9% of its purchasing power over
these 25 years.
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.
Every 1999 amount converts to 2024 at the same ratio, 1.88: $1,000 becomes
$1,883, and $10,000 becomes $18,829.

Year by year: CPI and the value of $100 from 1999
$100 from 1999 had already become $135 by
2011, on its way to $188 in 2024; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 8.0% in 2022, and prices fell 0.4% in 2009, the deepest deflation of the period.
In 2024, prices rose 2.9% and $100 from 1999 had the buying
power of $188; 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.
