What happened to prices between 1928 and 2026

Between 1928 and 2026, the Consumer Price Index went from 17.1 to 331.655. Cumulatively, prices increased 1839.5%, which works out to an average of 3.07% per year. Put differently, a dollar in 1928 bought what $0.05 buys in 2026.

Consumer prices fell 1.7% in 1928, the second straight year of mild decline even as the stock market climbed sharply, a widening gap between asset prices and the cost of living that later economists pointed to as an early warning sign. The Federal Reserve tightened policy repeatedly over the year, raising its discount rate in an effort to slow the flood of borrowed money pouring into stock purchases without derailing the broader economy, a balancing act it ultimately failed to manage. Herbert Hoover won the presidential election that November, defeating Democrat Al Smith on a platform built around continuing the prosperity of the Coolidge years; few voters or policymakers anticipated how quickly that prosperity would end. First-class postage remained at 2 cents, a price that had now held for nine straight years.
