What happened to prices between 2005 and 2006
Between 2005 and 2006, the Consumer Price Index went from 195.3 to 201.6.
Cumulatively, prices increased 3.2%, which works out to an average of
3.23% per year. Put differently, a dollar in 2005 bought what
$0.97 buys in 2006: the 2005 dollar
lost 3.1% of its purchasing power over
these 1 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 2006 at the same ratio, 1.03: $1,000 becomes
$1,032, and $10,000 becomes $10,323.
