What happened to prices between 1924 and 2011
Between 1924 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
3.01% per year. Put differently, a dollar in 1924 bought what
$0.08 buys in 2011: the 1924 dollar
lost 92.4% of its purchasing power over
these 87 years.
Consumer prices held flat in 1924, the CPI’s annual average unchanged from
1923 after swinging from a sharp postwar drop to a modest rise the year
before. That stability, extending the calm that had settled in after the
deflation of 1921 and 1922, became a defining feature of the rest of the
decade. Congress tightened immigration policy further with the Immigration
Act of 1924, signed May 26, which cut the national-origins quota from 3% of
each nationality’s 1910 census population to 2% of its 1890 population,
shifting admissions further toward northern and western Europe and
effectively excluding most immigration from Asia. Abroad, the U.S.-backed
Dawes Plan, adopted that August, reorganized Germany’s war reparations
payments and opened the way for American loans into the German economy,
helping stabilize European currencies after the hyperinflation that had
peaked in 1923. At home, Calvin Coolidge, who had served out
the remainder of Warren Harding’s term after his death the previous year,
won a full term of his own that November, campaigning on continued
prosperity and limited government. First-class postage remained at 2 cents,
a price unchanged since mid-1919.
Every 1924 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 1924
$100 from 1924 had already become $215 by
1969, 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 1924 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.
