Value of $100 in 1939, adjusted to 1973

What happened to prices between 1939 and 1973

Between 1939 and 1973, the Consumer Price Index went from 13.9 to 44.4. Cumulatively, prices increased 219.4%, which works out to an average of 3.47% per year. Put differently, a dollar in 1939 bought what $0.31 buys in 1973.

Consumer prices fell 1.4% in 1939, closing out a decade in which the CPI fell in six years and rose in four, leaving prices 18.7% below their 1929 level even after the mid-decade recovery. Measured against the start of the CPI’s modern record, prices still stood 40.4% above their 1913 level, a reminder that even a decade defined by deflation left the cost of living well above where it had been a generation earlier. The decade’s final months reset the economic picture entirely. Germany invaded Poland on September 1, and Britain and France declared war two days later; the United States stayed formally neutral under the Neutrality Acts, but Allied orders for war materiel began flowing to American factories almost immediately, a demand shock that would do more to end the Depression over the next few years than any peacetime relief program had managed. Domestic policy kept building on the New Deal’s framework, too: the federal minimum wage rose to 30 cents an hour that October, the second step in the schedule set by the 1938 Fair Labor Standards Act. Amid it all, the New York World’s Fair opened April 30 in Queens, themed “The World of Tomorrow” and drawing tens of millions of visitors with exhibits on television and other technologies promising a more prosperous decade than the one just ending. First-class postage held at 3 cents.

The destination year: 1973

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.
