What happened to prices between 1966 and 2026
Between 1966 and 2026, the Consumer Price Index went from 32.4 to 332.243.
Cumulatively, prices increased 925.4%, which works out to an average of
3.96% per year. Put differently, a dollar in 1966 bought what
$0.10 buys in 2026: the 1966 dollar
lost 90.2% of its purchasing power over
these 60 years.
Consumer prices rose 2.9% in 1966, nearly double 1965’s
1.6% as Vietnam War spending kept climbing without an offsetting tax
increase, pushing the economy closer to capacity and prices higher along
with it. Medicare coverage took effect that July 1, extending federal
health insurance to roughly 19 million Americans age 65 and older under
the program signed into law the year before. The Federal Reserve had
already moved to cool the overheating economy, raising its discount rate
the previous December over White House objections; the tightening carried
into 1966 as the first postwar credit crunch, freezing parts of the
housing and municipal bond markets even as inflation kept climbing. Congress widened
the wage floor’s reach that September 23, when the Fair Labor Standards
Amendments of 1966 set a $1.40 minimum wage effective the following
February and extended coverage to roughly 9 million more workers in
retail, hospitals, schools, and other services not previously covered.
Consumer prices finished 1966 227.3% above their 1913
level. First-class postage held at 5 cents, and the minimum wage stayed at
$1.25 an hour for the rest of the year.
Every 1966 amount converts to 2026 at the same ratio, 10.25: $1,000 becomes
$10,254, and $10,000 becomes $102,544.
