What happened to prices between 1956 and 2021
Between 1956 and 2021, the Consumer Price Index went from 27.2 to 270.97.
Cumulatively, prices increased 896.2%, which works out to an average of
3.60% per year. Put differently, a dollar in 1956 bought what
$0.10 buys in 2021: the 1956 dollar
lost 90.0% of its purchasing power over
these 65 years.
Consumer prices rose 1.5% in 1956, a return to mild inflation after they had
fallen 0.4% in 1955, the only annual decline of the decade. The two years sat
in the calmest stretch of the postwar index, a lull between the Korean War
price surge earlier in the 1950s and the acceleration that would return in
the 1970s. Congress had already raised the wage floor into that calm: the
Fair Labor Standards Amendments of 1955, signed the previous August, took
effect March 1 and lifted the federal minimum wage from 75 cents to $1 an
hour, the first increase since 1950. Eisenhower signed a longer-lasting
commitment on June 29, the Federal-Aid Highway Act, funding 41,000 miles of
controlled-access highway at 90% federal cost to build the Interstate
System, the largest public-works program the country had undertaken. He won
a second term that November, carrying 41 states and about 57% of the
popular vote in a rematch against Adlai Stevenson. Abroad, the Suez Crisis
broke the calm on the supply side: Egypt nationalized the canal on July 26,
and after Israel invaded the Sinai on October 29 with British and French
forces following, the canal’s closure and damaged pipelines squeezed oil
shipments to Western Europe for months. Consumer prices stood 174.7% above
their 1913 level by 1956, up 94% since 1940
alone, even after a decade that had barely moved the index. First-class
postage held at 3 cents, unchanged since 1932.
Every 1956 amount converts to 2021 at the same ratio, 9.96: $1,000 becomes
$9,962, and $10,000 becomes $99,621.

Year by year: CPI and the value of $100 from 1956
$100 from 1956 had already become $403 by
1986, on its way to $996 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 5 years; the calculator above covers any pair of years.
The destination year: 2021
In 2021, prices rose 4.7% and $100 from 1956 had the buying
power of $996; 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.
