What happened to prices between 1975 and 2024
Between 1975 and 2024, the Consumer Price Index went from 53.8 to 313.689.
Cumulatively, prices increased 483.1%, which works out to an average of
3.66% per year. Put differently, a dollar in 1975 bought what
$0.17 buys in 2024: the 1975 dollar
lost 82.8% of its purchasing power over
these 49 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 2024 at the same ratio, 5.83: $1,000 becomes
$5,831, and $10,000 becomes $58,307.

Year by year: CPI and the value of $100 from 1975
$100 from 1975 had already become $310 by
1999, on its way to $583 in 2024; 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: 2024
In 2024, prices rose 2.9% and $100 from 1975 had the buying
power of $583; the year's average CPI of 313.689 is the level
behind every 2024 figure on this page.
2024 brought inflation close to normal without fully reaching it. Consumer
prices rose 2.9% on average, the smallest yearly increase since 2020, and the
December-to-December rate was also 2.9%. Gasoline averaged $3.30 a gallon,
below 2023’s $3.52. Shelter stayed the biggest driver of the index, so the
pace of price growth in categories that households can’t easily avoid, such as
rent and insurance, lagged the drop in goods and energy costs.
The Federal Reserve declared progress in September, cutting its policy rate
by half a point, the first reduction since the pandemic emergency, and then
by a quarter point in November and again in December. Mortgage rates near 7%
kept the housing market frozen for many would-be buyers.
Median household income was $83,730, the federal minimum wage stayed at $7.25,
and a first-class stamp rose to 73 cents in July. After the November election,
attention turned to how announced tariffs and tax policy might affect prices
in 2025.
