What happened to prices between 1924 and 1973
Between 1924 and 1973, the Consumer Price Index went from 17.1 to 44.4.
Cumulatively, prices increased 159.6%, which works out to an average of
1.97% per year. Put differently, a dollar in 1924 bought what
$0.39 buys in 1973: the 1924 dollar
lost 61.5% of its purchasing power over
these 49 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 1973 at the same ratio, 2.60: $1,000 becomes
$2,596, and $10,000 becomes $25,965.

Year by year: CPI and the value of $100 from 1924
$100 from 1924 had already become $141 by
1948, on its way to $260 in 1973; 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 2 years; the calculator above covers any pair of years.
The destination year: 1973
In 1973, prices rose 6.2% and $100 from 1924 had the buying
power of $260; the year's average CPI of 44.4 is the level
behind every 1973 figure on this page.
Consumer prices rose 6.2% in 1973, nearly double 1972’s 3.2%,
as Nixon’s wage and price controls were phased out through the year and
pressure the controls had been holding back broke loose. The bigger shock
arrived that October, when Arab oil-producing states embargoed exports to the
United States and other supporters of Israel in the Yom Kippur War. Crude
oil, which had traded around $3 a barrel, approached $12 by early 1974, and
gas lines became a fixture outside filling stations nationwide. Earlier in
the year, the Paris Peace Accords, signed that January 27, ended direct
American combat in Vietnam and set a 60-day deadline for withdrawing
remaining U.S. troops, even as fighting between North and South Vietnam went
on. Financial markets read the year correctly as a turning point: the Dow
Jones Industrial Average peaked at 1,051.70 on January 11, a level it would
not reach again until 1980, before the oil shock and rising interest rates
dragged it into a two-year bear market. A median household earned $10,512 in
1973, a new home sold for a median $32,500, and gas averaged 38.5 cents a
gallon, still under half of what the embargo’s effects would bring the
following year. Consumer prices stood 348.5% above their
1913 level by year’s end, with the decade’s worst inflation
still ahead.
