What happened to prices between 2005 and 2020
Between 2005 and 2020, the Consumer Price Index went from 195.3 to 258.811.
Cumulatively, prices increased 32.5%, which works out to an average of
1.89% per year. Put differently, a dollar in 2005 bought what
$0.75 buys in 2020: the 2005 dollar
lost 24.5% of its purchasing power over
these 15 years.
Inflation rose to 3.4% in 2005, up from 2.7% in 2004, as gasoline averaged $2.30 a gallon,
compared with $1.88 the year before. Hurricane Katrina made landfall on August 29, and with
Hurricane Rita weeks later it disrupted Gulf Coast refining, pushing the national average
price past $3 in early September. The Federal Reserve raised its policy rate at every meeting,
from 2.25% to 4.25%, to keep energy costs from feeding into other prices. The median household
earned about $46,300, up 4.5% from 2004, but the median new home price rose a further 9%, to
$240,900. In April, Congress passed a bankruptcy law that made it harder to clear debts. A
first-class stamp stayed at 37 cents until January 2006, and the federal minimum wage stayed
at $5.15.
Every 2005 amount converts to 2020 at the same ratio, 1.33: $1,000 becomes
$1,325, and $10,000 becomes $13,252.

Year by year: CPI and the value of $100 from 2005
$100 from 2005 had already become $118 by
2012, on its way to $133 in 2020; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 3.8% in 2008, and prices fell 0.4% in 2009, the deepest deflation of the period.
In 2020, prices rose 1.2% and $100 from 2005 had the buying
power of $133; the year's average CPI of 258.811 is the level
behind every 2020 figure on this page.
2020 was the year the pandemic rewired the price data without triggering the
inflation spike that followed it. Consumer prices rose just 1.2% for the
year, the mildest pace since 2015, as COVID-19 lockdowns emptied roads,
closed airports, and crushed energy demand. Oil told the starkest story: on
April 20, U.S. crude futures fell to about negative $37 a barrel, the first
negative settlement in the market’s history, as storage capacity ran out and no one
wanted the physical barrels. Gasoline followed it down, falling to about
$1.80 a gallon nationally that month before recovering to average $2.17 for
the year. Grocery prices moved the other way: pantry stocking and
meatpacking-plant disruptions pushed food-at-home costs up faster than
usual, a rare case of food and energy pulling the index in opposite
directions. Washington answered with the $2.2 trillion CARES Act, signed
March 27, which sent $1,200 payments to most adults and added $600 a week
to unemployment benefits as states ordered widespread business closures.
The Federal Reserve cut its policy rate to near zero in two emergency moves
that same month and pledged to buy Treasury and mortgage bonds “in the
amounts needed” to keep credit markets working, an open-ended commitment
beyond even its 2008 response. None of it showed up in the CPI yet: the
stimulus, the supply shocks, and the reopening whiplash that followed would
build into the fastest inflation in four decades over the next two years.
