What happened to prices between 1924 and 2005
Between 1924 and 2005, the Consumer Price Index went from 17.1 to 195.3.
Cumulatively, prices increased 1042.1%, which works out to an average of
3.05% per year. Put differently, a dollar in 1924 bought what
$0.09 buys in 2005: the 1924 dollar
lost 91.2% of its purchasing power over
these 81 years.
Consumer prices held flat in 1924, the CPI’s annual average unchanged from
1923 after swinging from a sharp postwar drop to a modest rise the year
before. That stability, extending the calm that had settled in after the
deflation of 1921 and 1922, became a defining feature of the rest of the
decade. Congress tightened immigration policy further with the Immigration
Act of 1924, signed May 26, which cut the national-origins quota from 3% of
each nationality’s 1910 census population to 2% of its 1890 population,
shifting admissions further toward northern and western Europe and
effectively excluding most immigration from Asia. Abroad, the U.S.-backed
Dawes Plan, adopted that August, reorganized Germany’s war reparations
payments and opened the way for American loans into the German economy,
helping stabilize European currencies after the hyperinflation that had
peaked in 1923. At home, Calvin Coolidge, who had served out
the remainder of Warren Harding’s term after his death the previous year,
won a full term of his own that November, campaigning on continued
prosperity and limited government. First-class postage remained at 2 cents,
a price unchanged since mid-1919.
Every 1924 amount converts to 2005 at the same ratio, 11.42: $1,000 becomes
$11,421, and $10,000 becomes $114,211.

The destination year: 2005
In 2005, prices rose 3.4% and $100 from 1924 had the buying
power of $1,142; 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.
