Between 1945 and 1981, the Consumer Price Index went from 18 to 90.9.
Cumulatively, prices increased 405.0%, which works out to an average of
4.60% per year. Put differently, a dollar in 1945 bought what
$0.20 buys in 1981.
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.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1945 spending costs in 1981, by category:

The destination year: 1981
1981 was the year the inflation fever finally broke, at an extraordinary price.
Consumer prices rose 10.3%, the second year of back-to-back double-digit
inflation and the last time the U.S. would see one. To end it, Paul Volcker’s
Federal Reserve drove its policy rate above 19% and let borrowing costs go
where they may: a 30-year mortgage cost more than 18% by autumn, car loans and
business credit froze, and homebuilders mailed the Fed two-by-fours in protest.
The squeeze tipped the economy into recession in July, the deep 1981–82
downturn that would push unemployment past 10%. But it worked. Inflation fell
by nearly half within a year and to under 4% by 1983, the disinflation that
defined the following two decades. Even the price of mailing a letter told the
year’s story: postage went up twice in eight months.
