What happened to prices between 1928 and 2011
Between 1928 and 2011, the Consumer Price Index went from 17.1 to 224.939.
Cumulatively, prices increased 1215.4%, which works out to an average of
3.15% per year. Put differently, a dollar in 1928 bought what
$0.08 buys in 2011: the 1928 dollar
lost 92.4% of its purchasing power over
these 83 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 2011 at the same ratio, 13.15: $1,000 becomes
$13,154, and $10,000 becomes $131,543.

Year by year: CPI and the value of $100 from 1928
$100 from 1928 had already become $204 by
1968, on its way to $1,315 in 2011; 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: 2011
In 2011, prices rose 3.2% and $100 from 1928 had the buying
power of $1,315; the year's average CPI of 224.939 is the level
behind every 2011 figure on this page.
2011 brought the fastest inflation of the post-recession recovery. Consumer
prices rose 3.2%, roughly double the 2010 pace, and the cause was mostly at the
pump and the grocery store. Unrest across the Middle East and North Africa,
including the war in Libya, pushed gasoline to an annual average of $3.52 a
gallon, the highest yearly figure recorded to that point. Food prices also
rose faster than the overall index.
Household budgets did not keep up. The median household income was $50,054,
barely above the year before, and the median new home sold for about $227,200.
The federal minimum wage stayed at $7.25 and a first-class stamp at 44 cents.
Policy stayed loose. The Federal Reserve kept its policy rate near zero and
launched Operation Twist in September to lower long-term rates. Washington
spent the summer in a debt-ceiling fight that ended in S&P’s August downgrade
of the U.S. credit rating. The inflation spike proved temporary: the
2011 rate was the high point of the early 2010s, and prices grew more slowly
in every year that followed until 2017.
