What happened to prices between 1915 and 2005
Between 1915 and 2005, the Consumer Price Index went from 10.1 to 195.3.
Cumulatively, prices increased 1833.7%, which works out to an average of
3.35% per year. Put differently, a dollar in 1915 bought what
$0.05 buys in 2005: the 1915 dollar
lost 94.8% of its purchasing power over
these 90 years.
Consumer prices rose 1.0% in 1915, the second straight year of near-flat
inflation before the wartime price surges of 1916 through 1918. The year’s
defining event had nothing to do with prices directly: a German submarine
sank the British liner Lusitania off the Irish coast on May 7, killing 128
Americans and hardening U.S. opinion against Germany two years before the
country entered the war. Economically, 1915 was a turning point of a
different kind. A recession that had dragged on since 1913 began lifting as
Britain and France placed growing orders for steel, munitions, and other war
materiel with American manufacturers, and U.S. exports to the Allied powers
climbed sharply through the year. That demand would keep building through
1916, eventually pulling prices up with it. On the regulatory
side, the Federal Trade Commission opened for business in March, taking on
enforcement of the Clayton Antitrust Act that Congress had passed the
previous fall. A first-class stamp still cost 2 cents, unchanged since 1885
and still two years from its first wartime increase.
Every 1915 amount converts to 2005 at the same ratio, 19.34: $1,000 becomes
$19,337, and $10,000 becomes $193,366.

The destination year: 2005
In 2005, prices rose 3.4% and $100 from 1915 had the buying
power of $1,934; the year's average CPI of 195.3 is the level
behind every 2005 figure on this page.
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.
