What happened to prices between 1999 and 2023
Between 1999 and 2023, the Consumer Price Index went from 166.6 to 304.702.
Cumulatively, prices increased 82.9%, which works out to an average of
2.55% per year. Put differently, a dollar in 1999 bought what
$0.55 buys in 2023: the 1999 dollar
lost 45.3% of its purchasing power over
these 24 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 2023 at the same ratio, 1.83: $1,000 becomes
$1,829, and $10,000 becomes $18,289.

Year by year: CPI and the value of $100 from 1999
$100 from 1999 had already become $135 by
2011, on its way to $183 in 2023; 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 2023, prices rose 4.1% and $100 from 1999 had the buying
power of $183; the year's average CPI of 304.702 is the level
behind every 2023 figure on this page.
2023 was the year inflation came down without a recession. Consumer prices
rose 4.1% on average, roughly half of 2022’s 8.0%, and the December-to-December
rate fell to 3.4%. Gasoline averaged $3.52 a gallon, well below the 2022
average, and supply-chain pressure on goods eased. Shelter, restaurant meals,
and other services stayed expensive, so the CPI kept rising at a rate well
above the pre-pandemic pace.
The Federal Reserve completed its rate-hiking campaign in July, taking the
policy rate to 5.25–5.50%, the highest level in 22 years. The effects showed
up in banking: Silicon Valley Bank failed in March after rate increases eroded
the value of its bond portfolio, the second-largest bank failure in U.S.
history at the time. Despite that, unemployment stayed under 4% all year.
Median household income was $80,610 according to the Census Bureau. The
federal minimum wage stayed at $7.25, and a first-class stamp rose to 66 cents
in July.
