$100 in 1974 has a different purchasing power than $100 today. Over the 52 years since 1974, U.S. consumer prices have risen substantially, so it takes more dollars now to buy the same goods. RaiseGauge computes the exact figure from the BLS CPI-U index.
This is the same inflation adjustment used to compare wages, prices, and budgets across decades: the honest way to ask what something “cost back then” is to convert it into today's dollars, because otherwise you are comparing dollars of different sizes. The page shows the equivalent value today, the total inflation since 1974, and a year-by-year chart of how the figure grew.
Compare nearby years: $100 in 1971 · $100 in 1972 · $100 in 1973 · $100 in 1975 · $100 in 1976 · $100 in 1977.
