Between 1940 and 1968, the Consumer Price Index went from 14 to 34.8.
Cumulatively, prices increased 148.6%, which works out to an average of
3.31% per year. Put differently, a dollar in 1940 bought what
$0.40 buys in 1968.
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 1968, 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 4.2% in 1968, up sharply from 1967’s
3.1% and the fastest pace in 17 years, as Vietnam War spending and a tight
labor market pushed inflation higher despite the Federal Reserve’s
earlier tightening. The year was marked by political violence: Martin
Luther King Jr. was assassinated on a motel balcony in Memphis on April
4, touching off rioting in more than 100 cities, and Robert F. Kennedy was
shot in Los Angeles on June 5, moments after winning California’s
Democratic presidential primary, and died the next day. Washington tried
to answer the inflation problem directly that June 28, when Congress
passed a 10% income tax surcharge, the Revenue and Expenditure Control
Act, temporarily raising taxes and cutting spending to cool an economy
overheated by war and Great Society outlays; prices kept accelerating
anyway. The cost of living rose in smaller, more visible ways too:
first-class postage climbed to 6 cents that January 7, and the minimum
wage rose to $1.60 an hour that February 1, the final step of the
increase Congress had set two years earlier. Consumer prices finished
1968 251.5% above their 1913 level.
