Value of $100 in 1940, adjusted to 1958

What happened to prices between 1940 and 1958

Between 1940 and 1958, the Consumer Price Index went from 14 to 28.9. Cumulatively, prices increased 106.4%, which works out to an average of 4.11% per year. Put differently, a dollar in 1940 bought what $0.48 buys in 1958.

Consumer prices rose 0.7% in 1940, snapping 1939’s decline and marking the first increase since 1937. The gain was modest, and the CPI still stood 18.1% below its 1929 peak, a reminder of how far the recovery from the Depression’s trough had left to go even as defense orders from Britain and France began reaching American factories. War was already reshaping domestic policy well before it touched American soil. Congress passed the Selective Training and Service Act that September, the country’s first peacetime draft, requiring men aged 21 to 35 to register and authorizing the induction of up to 900,000 men a year, more than a year before Pearl Harbor. That November, Franklin Roosevelt won an unprecedented third term, defeating Republican Wendell Willkie after campaigning on keeping the United States out of the war then consuming Europe and Asia. The promise would not hold much longer: within two years, wartime demand would push consumer prices up faster than at any point since the aftermath of World War I. First-class postage held at 3 cents, and the federal minimum wage stayed at 30 cents an hour, the level set the previous October under the Fair Labor Standards Act.

The destination year: 1958

Consumer prices rose 2.8% in 1958, down only slightly from 1957’s 3.3% even as the country sank into the sharpest postwar recession to that point, an early sign that inflation and a shrinking economy could coexist rather than trade off against each other. The National Bureau of Economic Research dates the downturn’s trough to that April, with unemployment peaking near 7.5% that summer, the worst reading since the 1930s. The Post Office raised first-class postage to 4 cents that August 1, up from 3 cents, the rate’s first change since 1932. Washington answered the Soviet Union’s technological lead that summer too: Eisenhower signed the National Aeronautics and Space Act on July 29, establishing NASA, which opened for business that October 1 to compete with the Soviet space program after the shock of Sputnik the year before. Consumer prices finished 1958 191.9% above their 1913 level. The minimum wage held at $1.00 an hour, and first-class postage rose to 4 cents that August, the first increase since 1932.
