Between 1966 and 1990, the Consumer Price Index went from 32.4 to 130.7.
Cumulatively, prices increased 303.4%, which works out to an average of
5.98% per year. Put differently, a dollar in 1966 bought what
$0.25 buys in 1990.
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.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1966 spending costs in 1990, by category:

Not shown because the BLS began these indexes after 1966: housing (1967–), recreation (1993–), education & communication (1993–).
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
