What happened to prices between 1940 and 2004
Between 1940 and 2004, the Consumer Price Index went from 14 to 188.9.
Cumulatively, prices increased 1249.3%, which works out to an average of
4.15% per year. Put differently, a dollar in 1940 bought what
$0.07 buys in 2004: the 1940 dollar
lost 92.6% of its purchasing power over
these 64 years.
Consumer prices rose 0.7% in 1940, snapping 1939’s decline
and marking the first increase since 1937. The gain was modest, and the CPI
still stood 18.1% below its 1929 peak, a reminder of how far
the recovery from the Depression’s trough had left to go even as defense
orders from Britain and France began reaching American factories. War was
already reshaping domestic policy well before it touched American soil.
Congress passed the Selective Training and Service Act that September, the
country’s first peacetime draft, requiring men aged 21 to 35 to register and
authorizing the induction of up to 900,000 men a year, more than a year
before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented
third term, defeating Republican Wendell Willkie after campaigning on
keeping the United States out of the war then consuming Europe and Asia. The
promise would not hold much longer: within two years, wartime demand would
push consumer prices up faster than at any point since the aftermath of
World War I. First-class postage held at 3 cents, and the federal minimum
wage stayed at 30 cents an hour, the level set the previous October under
the Fair Labor Standards Act.
Every 1940 amount converts to 2004 at the same ratio, 13.49: $1,000 becomes
$13,493, and $10,000 becomes $134,929.

gallon, doing much of the work. Crude oil passed $50 a barrel in October on rising demand
from China and India. The Federal Reserve raised rates for the first time in four years on
