What happened to prices between 1927 and 1980
Between 1927 and 1980, the Consumer Price Index went from 17.4 to 82.4.
Cumulatively, prices increased 373.6%, which works out to an average of
2.98% per year. Put differently, a dollar in 1927 bought what
$0.21 buys in 1980: the 1927 dollar
lost 78.9% of its purchasing power over
these 53 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 $153 by
1953, on its way to $474 in 1980; 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: 1980
In 1980, prices rose 13.5% and $100 from 1927 had the buying
power of $474; the year's average CPI of 82.4 is the level
behind every 1980 figure on this page.
1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that
single year, mortgage rates were climbing toward 16%, and the Federal Reserve
under Paul Volcker was administering the painful interest-rate medicine that
would finally break the inflationary spiral, at the cost of the deep 1981–82
recession. No single year looms larger in how Americans think about inflation.
