Updated June 1, 2026 · BLS / FRED (CPIAUCSL)
$1 in 1980 is worth $4.29 in today's dollars, adjusted by the official U.S. Consumer Price Index (CPI-U), which rose 329% since then. BLS/FRED data through June 1, 2026.
A single dollar in 1980 was already pocket change, useful only for the smallest purchases. That makes it the sharpest illustration of the year inflation peaked at 13.5%, with the Volcker Fed pushing rates near 20% to break it. The adjustment to today's dollars isn't a gain; it's the cost of inflation alone. It simply shows how little of its 1980 reach a dollar would keep traveling through that period.
