What happened to prices between 1965 and 2021
Between 1965 and 2021, the Consumer Price Index went from 31.5 to 270.97.
Cumulatively, prices increased 760.2%, which works out to an average of
3.92% per year. Put differently, a dollar in 1965 bought what
$0.12 buys in 2021: the 1965 dollar
lost 88.4% of its purchasing power over
these 56 years.
Consumer prices rose 1.6% in 1965, up from 1964’s 1.3% in a
pickup that economists later mark as the start of the Great
Inflation, a run of accelerating
price increases driven by rising Vietnam War spending layered on top of
new Great Society programs. The war itself escalated on the ground that
March, when about 3,500 Marines came ashore at Da Nang, the first American
combat troops committed to Vietnam; troop levels would climb toward
200,000 by year’s end. Domestic policy expanded just as fast: Medicare and
Medicaid became law that July 30, creating federal health insurance for
older and low-income Americans, and the Voting Rights Act, signed that
August 6, banned literacy tests and other devices used to disenfranchise
Black voters. The civil rights movement’s gains coexisted with urban
unrest that same August, when a highway patrol traffic stop in the Watts
neighborhood of Los Angeles set off six days of rioting that left 34
people dead. Consumer prices finished 1965 218.2% above their
1913 level. First-class postage held at 5 cents, and the
minimum wage stayed at $1.25 an hour.
Every 1965 amount converts to 2021 at the same ratio, 8.60: $1,000 becomes
$8,602, and $10,000 becomes $86,022.

Year by year: CPI and the value of $100 from 1965
$100 from 1965 had already become $459 by
1993, on its way to $860 in 2021; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 13.5% in 1980, and prices fell 0.4% in 2009, the deepest deflation of the period.
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 2021
In 2021, prices rose 4.7% and $100 from 1965 had the buying
power of $860; the year's average CPI of 270.97 is the level
behind every 2021 figure on this page.
2021 was the year inflation stopped being background noise. Consumer prices
rose 4.7% on average for the year, and the pace kept building as the months
went on: by December, the 12-month rate had reached 7.0%, the highest since
1982. The proximate cause was a supply chain that could not keep up with a
fast-reopening economy. A global semiconductor shortage choked new car
production and pushed used vehicle prices up by more than a third, the
single largest line item in the year’s inflation math. Lumber, appliances,
and shipping capacity told versions of the same story: demand snapped back
faster than factories, ports, and truckers could handle it. Washington added
fuel in March with the $1.9 trillion American Rescue Plan, on top of the
relief already in the pipeline since 2020. For most of the year, the Federal
Reserve called the price surge “transitory,” a temporary reopening effect
expected to fade on its own, and held its policy rate near zero. By
November, with inflation still climbing, the Fed reversed course and began
winding down its bond purchases, the first step toward the rate hikes that
would follow in 2022. Gas averaged $3.01 a gallon for the year, up from
about $2.17 in 2020, while the federal minimum wage held at $7.25,
unchanged since 2009. In hindsight, 2021 reads as the hinge year: the point
where “transitory” inflation became the multi-year fight the Fed spent the
next two years trying to win.
