Value of $100 in 1979, adjusted to 2026

What happened to prices between 1979 and 2026

Between 1979 and 2026, the Consumer Price Index went from 72.6 to 332.243. Cumulatively, prices increased 357.6%, which works out to an average of 3.29% per year. Put differently, a dollar in 1979 bought what $0.22 buys in 2026: the 1979 dollar lost 78.1% of its purchasing power over these 47 years.

Consumer prices rose 11.3% in 1979, the fastest pace since 1947 and the decade’s second bout of double-digit inflation after 1974’s 11.0%. The trigger was familiar: the Iranian Revolution that January halted Iran’s oil exports, and panic buying amplified the shortage, sending crude prices sharply higher over the year and motorists back into gas lines, with some states reviving the odd-even rationing last seen in 1974. Paul Volcker, appointed Federal Reserve chairman that August, responded with a strategy shift announced that October: the Fed would target the money supply directly and let interest rates rise as high as necessary to break inflation, whatever the short-term cost. That cost would arrive as a deep recession in 1981-82, but by year’s end 1979 had already delivered enough turmoil on its own. A reactor at the Three Mile Island plant near Harrisburg, Pennsylvania, suffered a partial core meltdown that March 28, the worst commercial nuclear accident in U.S. history, and on November 4, militants in Tehran stormed the U.S. embassy and took 52 Americans hostage, beginning a 444-day crisis that consumed the rest of Carter’s presidency. A median household earned $16,461 in 1979, a new home sold for a median $62,900, and gas jumped to 86 cents a gallon. Consumer prices finished the decade 97.8% above where they stood in 1969, very nearly doubling in ten years, and stood 633.3% above their 1913 level. The 1970s had opened with inflation cooling from the 1969 spike and closed with prices rising faster than at any point since 1947, setting up the Great Inflation’s final act in 1980.
