What happened to prices between 1975 and 2023
Between 1975 and 2023, the Consumer Price Index went from 53.8 to 304.702.
Cumulatively, prices increased 466.4%, which works out to an average of
3.68% per year. Put differently, a dollar in 1975 bought what
$0.18 buys in 2023: the 1975 dollar
lost 82.3% of its purchasing power over
these 48 years.
Consumer prices rose 9.1% in 1975, easing slightly from 1974’s
11.0% but still running far above anything the country had experienced before
the decade began. The recession that started in November 1973, the deepest
since the Great Depression, bottomed out that March, yet unemployment kept
climbing through the year and touched 9%, a combination of high inflation and
high joblessness that had no precedent in the postwar data. Vietnam ended
that April 30, when North Vietnamese forces captured Saigon and the last
Americans were evacuated by helicopter from the U.S. embassy roof. Fiscal
strain hit closer to home too: New York City, facing bankruptcy after years
of borrowing to paper over budget gaps, asked Washington for help that
October. President Ford’s initial refusal produced the Daily News headline
“Ford to City: Drop Dead,” though he ultimately signed a federal loan package
that December. Amid the gloom, Bill Gates and Paul Allen founded Microsoft
that April in Albuquerque, New Mexico, to sell a version of the BASIC
programming language for the Altair 8800, one of the first personal
computers sold to hobbyists. A median household earned $11,800 in 1975, a new
home sold for a median $39,300, and first-class postage held at 10 cents,
unchanged since 1974’s increase. Consumer prices stood 443.4%
above their 1913 level, with the decade barely past its
midpoint.
Every 1975 amount converts to 2023 at the same ratio, 5.66: $1,000 becomes
$5,664, and $10,000 becomes $56,636.

Year by year: CPI and the value of $100 from 1975
$100 from 1975 had already become $310 by
1999, on its way to $566 in 2023; 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: 2023
In 2023, prices rose 4.1% and $100 from 1975 had the buying
power of $566; the year's average CPI of 304.702 is the level
behind every 2023 figure on this page.
2023 was the year inflation came down without a recession. Consumer prices
rose 4.1% on average, roughly half of 2022’s 8.0%, and the December-to-December
rate fell to 3.4%. Gasoline averaged $3.52 a gallon, well below the 2022
average, and supply-chain pressure on goods eased. Shelter, restaurant meals,
and other services stayed expensive, so the CPI kept rising at a rate well
above the pre-pandemic pace.
The Federal Reserve completed its rate-hiking campaign in July, taking the
policy rate to 5.25–5.50%, the highest level in 22 years. The effects showed
up in banking: Silicon Valley Bank failed in March after rate increases eroded
the value of its bond portfolio, the second-largest bank failure in U.S.
history at the time. Despite that, unemployment stayed under 4% all year.
Median household income was $80,610 according to the Census Bureau. The
federal minimum wage stayed at $7.25, and a first-class stamp rose to 66 cents
in July.
