What happened to prices between 1966 and 2025
Between 1966 and 2025, the Consumer Price Index went from 32.4 to 321.943.
Cumulatively, prices increased 893.7%, which works out to an average of
3.97% per year. Put differently, a dollar in 1966 bought what
$0.10 buys in 2025: the 1966 dollar
lost 89.9% of its purchasing power over
these 59 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 2025 at the same ratio, 9.94: $1,000 becomes
$9,937, and $10,000 becomes $99,365.

Year by year: CPI and the value of $100 from 1966
$100 from 1966 had already become $484 by
1996, on its way to $994 in 2025; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 13.5% in 1980, and prices fell 0.4% in 2009, the deepest deflation of the period.
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 2025
In 2025, prices rose 2.6% and $100 from 1966 had the buying
power of $994; the year's average CPI of 321.943 is the level
behind every 2025 figure on this page.
2025 was a year of trade policy and data disruptions rather than an
inflation surge. Consumer prices rose 2.6% on average, a step down from
2024’s 2.9% and well below the 8.0% of 2022. Tariffs announced in April
pushed up prices for some imported goods, including furniture, apparel, and
auto parts, but the effect on the overall index was smaller than many
forecasters feared at the start of the year, in part because retailers
absorbed some of the cost and demand for services stayed steady.
The Federal Reserve held its policy rate steady through the first half of the
year, then began cutting again in September, lowering it in three quarter-point
steps to 3.50–3.75% by December.
The federal government shutdown that began October 1 lasted 43 days, and the
Bureau of Labor Statistics did not publish a CPI for October 2025 because the
survey data could not be collected. The federal minimum wage stayed at $7.25,
and a first-class stamp rose to 78 cents in July.
