$100 in 1970 is worth $883.47 in today's dollars, adjusted by the official U.S. Consumer Price Index (CPI-U), which rose 783% since then. BLS/FRED data through June 1, 2026.
One hundred dollars in 1970 was real money for a household — a meaningful chunk of a weekly budget, not pocket change. Watching it restated in today's dollars shows the 1970s great inflation working on a sum people actually planned around. The figure isn't growth; it's the same purchasing power, re-priced after two oil shocks pushed annual inflation past 13%. It measures only how much the dollar's reach shrank over the period.
