What happened to prices between 1940 and 2012

Between 1940 and 2012, the Consumer Price Index went from 14 to 229.594. Cumulatively, prices increased 1540.0%, which works out to an average of 3.96% per year. Put differently, a dollar in 1940 bought what $0.06 buys in 2012: the 1940 dollar lost 93.9% of its purchasing power over these 72 years.

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: 2012

In 2012, prices rose 2.1% and $100 from 1940 had the buying power of $1,640; the year's average CPI of 229.594 is the level behind every 2012 figure on this page.

2012 put a number on what the Federal Reserve was aiming for. In January the Fed announced a 2% inflation target, and consumer prices rose 2.1% for the year, almost exactly on it. Gasoline averaged $3.62 a gallon, another annual high, but the pace of increase cooled from 2011’s 3.2% as food and core prices grew more slowly.

The bigger story was housing and jobs. Home prices began to recover, and the median new home sold for about $245,200, up from $227,200 the year before. Median household income was $51,017. The federal minimum wage held at $7.25, and a first-class stamp rose to 45 cents.

In September the Fed started a third round of asset purchases, this one with no fixed end date, aimed at lowering unemployment. Overseas, the European Central Bank’s July pledge to do “whatever it takes” to save the euro calmed bond markets. A summer drought across the Midwest drove corn and soybean prices to records, a shock that reached grocery shelves only partly, because most of what shoppers pay for food covers processing and transport rather than raw crops.
