What happened to prices between 1927 and 1986
Between 1927 and 1986, the Consumer Price Index went from 17.4 to 109.6.
Cumulatively, prices increased 529.9%, which works out to an average of
3.17% per year. Put differently, a dollar in 1927 bought what
$0.16 buys in 1986: the 1927 dollar
lost 84.1% of its purchasing power over
these 59 years.
Consumer prices fell 1.7% in 1927, a mild retreat after three years of
gradual increases and part of a shallow up-and-down pattern that ran through
the second half of the decade. Aviation delivered the year’s signature
moment: Charles Lindbergh departed Roosevelt Field, New York, on May 20 and
landed at Le Bourget Field outside Paris roughly 33.5 hours later, the first
person to fly the Atlantic solo and nonstop. Detroit closed a chapter of its
own that May, when Ford halted the Model T’s production line after nearly 19
years and more than 15 million cars sold, idling tens of thousands of
workers while its factories retooled for the Model A. The Federal Reserve,
meeting with European central bankers that summer, cut its discount rate to
ease pressure on currencies still recovering from the war, a move later
cited by economists including Milton Friedman and Anna Schwartz as fuel for
the stock market speculation that built through the following two years.

Year by year: CPI and the value of $100 from 1927
$100 from 1927 had already become $161 by
1957, on its way to $630 in 1986; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 14.4% in 1947, and prices fell 9.9% in 1932, 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 1927 had the buying
power of $630; 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.
