What happened to prices between 1981 and 2024
Between 1981 and 2024, the Consumer Price Index went from 90.9 to 313.689.
Cumulatively, prices increased 245.1%, which works out to an average of
2.92% per year. Put differently, a dollar in 1981 bought what
$0.29 buys in 2024: the 1981 dollar
lost 71.0% of its purchasing power over
these 43 years.
1981 was the year the inflation fever finally broke, at an extraordinary price.
Consumer prices rose 10.3%, the second year of back-to-back double-digit
inflation and the last time the U.S. would see one. To end it, Paul Volcker’s
Federal Reserve drove its policy rate above 19% and let borrowing costs go
where they may: a 30-year mortgage cost more than 18% by autumn, car loans and
business credit froze, and homebuilders mailed the Fed two-by-fours in protest.
The squeeze tipped the economy into recession in July, the deep 1981–82
downturn that would push unemployment past 10%. But it worked. Inflation fell
by nearly half within a year and to under 4% by 1983, the disinflation that
defined the following two decades. Even the price of mailing a letter told the
year’s story: postage went up twice in eight months.
Every 1981 amount converts to 2024 at the same ratio, 3.45: $1,000 becomes
$3,451, and $10,000 becomes $34,509.

Year by year: CPI and the value of $100 from 1981
$100 from 1981 had already become $202 by
2003, on its way to $345 in 2024; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 8.0% in 2022, 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 1981 had the buying
power of $345; 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.
