What happened to prices between 1928 and 2018
Between 1928 and 2018, the Consumer Price Index went from 17.1 to 251.107.
Cumulatively, prices increased 1368.5%, which works out to an average of
3.03% per year. Put differently, a dollar in 1928 bought what
$0.07 buys in 2018: the 1928 dollar
lost 93.2% of its purchasing power over
these 90 years.
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.
Every 1928 amount converts to 2018 at the same ratio, 14.68: $1,000 becomes

Year by year: CPI and the value of $100 from 1928
$100 from 1928 had already become $260 by
1973, on its way to $1,468 in 2018; 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 5 years; the calculator above covers any pair of years.
The destination year: 2018
In 2018, prices rose 2.4% and $100 from 1928 had the buying
power of $1,468; the year's average CPI of 251.107 is the level
behind every 2018 figure on this page.
2018 was the peak of the late-2010s expansion. Consumer prices rose 2.4%,
the fastest since 2011, with gasoline averaging $2.72 a gallon after a summer
high. Unemployment fell to 3.7% in September, the lowest since 1969, and median
household income reached $63,179. The median new home sold for about $331,800,
and a first-class stamp cost 50 cents. The federal minimum wage was still $7.25.
Trade policy became a price factor for the first time in decades. New tariffs
on steel, aluminum, and a growing list of Chinese goods raised costs for
manufacturers and some consumer products, and retaliation cut into exports of
soybeans and other farm goods.
The Federal Reserve, led from February by Jerome Powell, raised rates four
times to 2.25–2.50%. A stock-market drop of nearly 20% in the fourth quarter
led the Fed to signal a pause in early 2019. Oil fell from over $75 a barrel in
October to below $50 by December, which pulled headline inflation lower going
into the next year.
