What happened to prices between 2005 and 2015
Between 2005 and 2015, the Consumer Price Index went from 195.3 to 237.017.
Cumulatively, prices increased 21.4%, which works out to an average of
1.95% per year. Put differently, a dollar in 2005 bought what
$0.82 buys in 2015: the 2005 dollar
lost 17.6% of its purchasing power over
these 10 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 2015 at the same ratio, 1.21: $1,000 becomes
$1,214, and $10,000 becomes $12,136.

Year by year: CPI and the value of $100 from 2005
$100 from 2005 had already become $112 by
2010, on its way to $121 in 2015; 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 2015, prices rose 0.1% and $100 from 2005 had the buying
power of $121; the year's average CPI of 237.017 is the level
behind every 2015 figure on this page.
2015 was almost a year with no inflation at all. Consumer prices rose 0.1%,
the smallest increase since the 2009 decline, because energy prices kept
falling. Gasoline averaged $2.45 a gallon, down from $3.37 in 2014, and a
strong dollar made imported goods cheaper. The picture was different outside
food and energy: core prices rose about 1.8% as rents and medical costs
climbed.
Incomes finally showed real progress. Median household income reached $56,516,
a large jump from $53,657, and the median new home sold for about $296,400. The
federal minimum wage stayed at $7.25, and a first-class stamp stayed at 49
cents.
The Federal Reserve chose December to end its zero-rate policy, raising the
target range to 0.25–0.50% for the first time since 2006. It moved even
though headline inflation was far under 2%, arguing that the drag from
energy was temporary. Earlier, a currency shift in China in August had shaken
global markets and pushed oil below $40 a barrel. Prices in 2015 ended
the year barely above their 2014 level.
