What happened to prices between 1951 and 2021
Between 1951 and 2021, the Consumer Price Index went from 26 to 270.97.
Cumulatively, prices increased 942.2%, which works out to an average of
3.41% per year. Put differently, a dollar in 1951 bought what
$0.10 buys in 2021: the 1951 dollar
lost 90.4% of its purchasing power over
these 70 years.
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.
Every 1951 amount converts to 2021 at the same ratio, 10.42: $1,000 becomes
$10,422, and $10,000 becomes $104,219.

Year by year: CPI and the value of $100 from 1951
$100 from 1951 had already become $422 by
1986, on its way to $1,042 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 1955, 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 1951 had the buying
power of $1,042; 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.
