What happened to prices between 1951 and 1986
Between 1951 and 1986, the Consumer Price Index went from 26 to 109.6.
Cumulatively, prices increased 321.5%, which works out to an average of
4.20% per year. Put differently, a dollar in 1951 bought what
$0.24 buys in 1986: the 1951 dollar
lost 76.3% of its purchasing power over
these 35 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 1986 at the same ratio, 4.22: $1,000 becomes
$4,215, and $10,000 becomes $42,154.

Year by year: CPI and the value of $100 from 1951
$100 from 1951 had already become $141 by
1969, on its way to $422 in 1986; 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 2 years; the calculator above covers any pair of years.
The destination year: 1986
In 1986, prices rose 1.9% and $100 from 1951 had the buying
power of $422; the year's average CPI of 109.6 is the level
behind every 1986 figure on this page.
1986 delivered the decade’s biggest one-year drop in inflation, and it came
almost entirely from a single source: oil. Saudi Arabia abandoned its policy
of restraining output to prop up prices, and world crude collapsed from
about $27 a barrel to under $10 by midyear. Gasoline, which had averaged
$1.12 a gallon in 1985, fell to 86 cents. With energy costs plunging,
headline CPI inflation for the year came in at just 1.9%, the lowest annual
rate since 1965 and a striking bookend to 1980’s 13.5% peak. The relief was
uneven: prices for most goods and services outside energy kept rising at a
moderate pace, so households that didn’t drive much or heat with oil felt
less of the difference. In October, Congress passed the Tax Reform Act of
1986, a bipartisan overhaul that cut the top individual income tax rate from
50% to 28% while closing many deductions and shelters, the broadest rewrite
of the federal tax code since World War II. Between cheap gas and falling
interest rates, 1986 read like proof that the inflationary 1970s were a
closed chapter, six years after the U.S. economy had felt anything but
calm.
