Between 1928 and 1980, the Consumer Price Index went from 17.1 to 82.4.
Cumulatively, prices increased 381.9%, which works out to an average of
3.07% per year. Put differently, a dollar in 1928 bought what
$0.21 buys in 1980.
Consumer prices fell 1.7% in 1928, the second straight year of mild decline
even as the stock market climbed sharply, a widening gap between asset
prices and the cost of living that later economists pointed to as an early
warning sign. The Federal Reserve tightened policy repeatedly over the year,
raising its discount rate in an effort to slow the flood of borrowed money
pouring into stock purchases without derailing the broader economy, a
balancing act it ultimately failed to manage. Herbert Hoover won the
presidential election that November, defeating Democrat Al Smith on a
platform built around continuing the prosperity of the Coolidge years; few
voters or policymakers anticipated how quickly that prosperity would end.
First-class postage remained at 2 cents, a price that had now held for nine
straight years.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1928 spending costs in 1980, by category:
Category
Avg. yearly inflation
$100 in 1928 →
All items (CPI-U)
3.07%
$482
Food
3.27%
$533
Apparel
2.51%
$364
Not shown because the BLS began these indexes after 1928: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), medical care (1935–), transportation (1935–), recreation (1993–), education & communication (1993–).
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1980
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.
