Between 1940 and 1951, the Consumer Price Index went from 14 to 26.
Cumulatively, prices increased 85.7%, which works out to an average of
5.79% per year. Put differently, a dollar in 1940 bought what
$0.54 buys in 1951.
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.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1940 spending costs in 1951, by category:

Not shown because the BLS began these indexes after 1940: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), recreation (1993–), education & communication (1993–).
Consumer prices rose 7.9% in 1951, up sharply from 1950’s
1.3% and the fastest increase since 1947, as Korean War buying and a
defense spending surge hit an economy still adjusting to peacetime. Much
of the jump came early in the year, before the government stepped in: the
Office of Price Stabilization imposed a general ceiling on prices January
26, and the Wage Stabilization Board froze wages soon after, the broadest
peacetime controls since the war began that June. The year’s more lasting
change came in monetary policy. On March 4, the Treasury and the Federal
Reserve signed the Accord, ending the Fed’s wartime obligation to hold
down interest rates on government bonds and freeing the central bank to
fight inflation on its own terms for the first time since 1942, a shift
that would shape Fed independence for decades. Congress raised taxes that
October to help pay for the war: the Revenue Act of 1951, signed October
20, lifted individual and corporate income taxes along with a range of
excise taxes, the third increase in taxes since fighting began in Korea.
Consumer prices finished 1951 162.6% above their 1913
level. First-class postage held at 3 cents, and the minimum wage stayed at
75 cents an hour.
