What happened to prices between 1945 and 2005
Between 1945 and 2005, the Consumer Price Index went from 18 to 195.3.
Cumulatively, prices increased 985.0%, which works out to an average of
4.05% per year. Put differently, a dollar in 1945 bought what
$0.09 buys in 2005: the 1945 dollar
lost 90.8% of its purchasing power over
these 60 years.
Consumer prices rose 2.3% in 1945, up from 1944’s 1.7% but
still modest, a rate that understated how much pressure had built up behind
wartime price and wage controls, which stayed largely in place even as the
conflict that justified them came to a close. The year opened with a shock
at home: Franklin Roosevelt died of a cerebral hemorrhage on April 12, less
than three months into an unprecedented fourth term, and Vice President
Harry Truman was sworn in that same afternoon. The war Roosevelt had led for
nearly four years ended without him. Germany surrendered on May 8, and
Japan surrendered on August 15, after atomic bombs fell on Hiroshima and
Nagasaki that month, with the formal signing aboard the USS Missouri on
September 2. Domestic policy kept moving even as the guns fell silent: the
federal minimum wage rose to 40 cents an hour that October 24, the final
step of the schedule Congress had built into the 1938 Fair Labor Standards
Act, up from 30 cents in 1939 and 25 cents at the law’s start. Consumer
prices stood 81.8% above their 1913 level, a gain that would
look modest next to what followed once wartime controls actually came off.
First-class postage held at 3 cents.
Every 1945 amount converts to 2005 at the same ratio, 10.85: $1,000 becomes
$10,850, and $10,000 becomes $108,500.

Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 2005
In 2005, prices rose 3.4% and $100 from 1945 had the buying
power of $1,085; 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.
