United States Inflation & Purchasing Power Calculator
In 1975, $100 represented approximately 0.8 weeks of average wages — a modest expense.
Oil Shocks, Double-Digit Inflation, and the End of Bretton Woods
The 1970s delivered the most severe peacetime inflation in US history. Two oil shocks (1973 and 1979) sent energy prices soaring and triggered double-digit inflation. By 1979, CPI inflation reached 13.3%. The purchasing power of a 1970 dollar had fallen by nearly 50% by 1980. Workers demanded — and received — dramatic wage increases, but wages consistently lagged prices. The Federal Reserve's decision to raise interest rates to 20% under Chairman Volcker in 1980 finally broke the inflation cycle, but at the cost of the worst recession since the Great Depression.
Between 1973 and 1975, the price of gasoline in the US tripled from 38 cents to over $1 per gallon. Adjusted for inflation, this remains one of the largest real-terms energy price shocks in history.
