What happened to prices between 1924 and 1986
Between 1924 and 1986, the Consumer Price Index went from 17.1 to 109.6.
Cumulatively, prices increased 540.9%, which works out to an average of
3.04% per year. Put differently, a dollar in 1924 bought what
$0.16 buys in 1986: the 1924 dollar
lost 84.4% of its purchasing power over
these 62 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 1986 at the same ratio, 6.41: $1,000 becomes
$6,409, and $10,000 becomes $64,094.

Year by year: CPI and the value of $100 from 1924
$100 from 1924 had already become $157 by
1954, on its way to $641 in 1986; 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: 1986
In 1986, prices rose 1.9% and $100 from 1924 had the buying
power of $641; the year's average CPI of 109.6 is the level
behind every 1986 figure on this page.
1986 delivered the decade’s biggest one-year drop in inflation, and it came
almost entirely from a single source: oil. Saudi Arabia abandoned its policy
of restraining output to prop up prices, and world crude collapsed from
about $27 a barrel to under $10 by midyear. Gasoline, which had averaged
$1.12 a gallon in 1985, fell to 86 cents. With energy costs plunging,
headline CPI inflation for the year came in at just 1.9%, the lowest annual
rate since 1965 and a striking bookend to 1980’s 13.5% peak. The relief was
uneven: prices for most goods and services outside energy kept rising at a
moderate pace, so households that didn’t drive much or heat with oil felt
less of the difference. In October, Congress passed the Tax Reform Act of
1986, a bipartisan overhaul that cut the top individual income tax rate from
50% to 28% while closing many deductions and shelters, the broadest rewrite
of the federal tax code since World War II. Between cheap gas and falling
interest rates, 1986 read like proof that the inflationary 1970s were a
closed chapter, six years after the U.S. economy had felt anything but
calm.
