What happened to prices between 1930 and 1990
Between 1930 and 1990, the Consumer Price Index went from 16.7 to 130.7.
Cumulatively, prices increased 682.6%, which works out to an average of
3.49% per year. Put differently, a dollar in 1930 bought what
$0.13 buys in 1990: the 1930 dollar
lost 87.2% of its purchasing power over
these 60 years.
Consumer prices fell 2.3% in 1930, a mild decline compared with what was
coming but the first sign that the summer 1929 downturn was not going to be
short. The National Bureau of Economic Research dates that contraction from
August 1929, and by the time it finally bottomed out in March 1933 it would
run 43 months, the longest of any downturn in the NBER’s chronology back to
1854. Congress made the trade picture worse in June, when President Hoover
signed the Smoot-Hawley Tariff Act, raising duties on more than 20,000
imported goods to some of the highest levels in a century. Trading partners
retaliated with tariffs of their own, and global trade volumes collapsed
over the next several years, deepening a downturn economists still debate
how much the tariff itself worsened. The financial system cracked that fall:
a regional banking panic culminated in the December 11 failure of the Bank
of United States in New York, at the time the largest bank failure in
American history, wiping out more than $200 million in deposits. It was the
first of four banking panics that would hit the country before 1933 was
out. Consumer prices still stood 68.7% above their 1913
starting point, but the direction had clearly turned. First-class postage
held at 2 cents, unchanged for eleven straight years.
Every 1930 amount converts to 1990 at the same ratio, 7.83: $1,000 becomes
$7,826, and $10,000 becomes $78,263.

Year by year: CPI and the value of $100 from 1930
$100 from 1930 had already become $177 by
1960, on its way to $783 in 1990; 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: 1990
In 1990, prices rose 5.4% and $100 from 1930 had the buying
power of $783; the year's average CPI of 130.7 is the level
behind every 1990 figure on this page.
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
