What happened to prices between 1975 and 2012

Between 1975 and 2012, the Consumer Price Index went from 53.8 to 229.594. Cumulatively, prices increased 326.8%, which works out to an average of 4.00% per year. Put differently, a dollar in 1975 bought what $0.23 buys in 2012.

Consumer prices rose 9.1% in 1975, easing slightly from 1974’s 11.0% but still running far above anything the country had experienced before the decade began. The recession that started in November 1973, the deepest since the Great Depression, bottomed out that March, yet unemployment kept climbing through the year and touched 9%, a combination of high inflation and high joblessness that had no precedent in the postwar data. Vietnam ended that April 30, when North Vietnamese forces captured Saigon and the last Americans were evacuated by helicopter from the U.S. embassy roof. Fiscal strain hit closer to home too: New York City, facing bankruptcy after years of borrowing to paper over budget gaps, asked Washington for help that October. President Ford’s initial refusal produced the Daily News headline “Ford to City: Drop Dead,” though he ultimately signed a federal loan package that December. Amid the gloom, Bill Gates and Paul Allen founded Microsoft that April in Albuquerque, New Mexico, to sell a version of the BASIC programming language for the Altair 8800, one of the first personal computers sold to hobbyists. A median household earned $11,800 in 1975, a new home sold for a median $39,300, and first-class postage held at 10 cents, unchanged since 1974’s increase. Consumer prices stood 443.4% above their 1913 level, with the decade barely past its midpoint.
