What happened to prices between 1945 and 2026
Between 1945 and 2026, the Consumer Price Index went from 18 to 332.243.
Cumulatively, prices increased 1745.8%, which works out to an average of
3.66% per year. Put differently, a dollar in 1945 bought what
$0.05 buys in 2026: the 1945 dollar
lost 94.6% of its purchasing power over
these 81 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 2026 at the same ratio, 18.46: $1,000 becomes
