What happened to prices between 2005 and 2018
Between 2005 and 2018, the Consumer Price Index went from 195.3 to 251.107.
Cumulatively, prices increased 28.6%, which works out to an average of
1.95% per year. Put differently, a dollar in 2005 bought what
$0.78 buys in 2018: the 2005 dollar
lost 22.2% of its purchasing power over
these 13 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 2018 at the same ratio, 1.29: $1,000 becomes
$1,286, and $10,000 becomes $12,858.

Year by year: CPI and the value of $100 from 2005
$100 from 2005 had already become $115 by
2011, on its way to $129 in 2018; 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 2018, prices rose 2.4% and $100 from 2005 had the buying
power of $129; the year's average CPI of 251.107 is the level
behind every 2018 figure on this page.
2018 was the peak of the late-2010s expansion. Consumer prices rose 2.4%,
the fastest since 2011, with gasoline averaging $2.72 a gallon after a summer
high. Unemployment fell to 3.7% in September, the lowest since 1969, and median
household income reached $63,179. The median new home sold for about $331,800,
and a first-class stamp cost 50 cents. The federal minimum wage was still $7.25.
Trade policy became a price factor for the first time in decades. New tariffs
on steel, aluminum, and a growing list of Chinese goods raised costs for
manufacturers and some consumer products, and retaliation cut into exports of
soybeans and other farm goods.
The Federal Reserve, led from February by Jerome Powell, raised rates four
times to 2.25–2.50%. A stock-market drop of nearly 20% in the fourth quarter
led the Fed to signal a pause in early 2019. Oil fell from over $75 a barrel in
October to below $50 by December, which pulled headline inflation lower going
into the next year.
