What happened to prices between 1984 and 2025
Between 1984 and 2025, the Consumer Price Index went from 103.9 to 321.943.
Cumulatively, prices increased 209.9%, which works out to an average of
2.80% per year. Put differently, a dollar in 1984 bought what
$0.32 buys in 2025: the 1984 dollar
lost 67.7% of its purchasing power over
these 41 years.
1984 was the year the recovery became a boom. Real GDP grew 7.2%, the
fastest calendar-year growth since 1951, as the tax cuts passed in 1981
combined with falling interest rates and rebuilding consumer confidence.
Unemployment, which had topped 10.8% just two years earlier, fell below
7.5%. Inflation ticked up to 4.3% from 3.2% the year before, but nothing
close to a return of the 1970s wage-price spiral: the Federal Reserve under
Paul Volcker kept policy tight enough to hold the line while growth ran hot.
The strength of the expansion, branded “Morning in America” in President
Reagan’s reelection campaign, carried him to a 49-state landslide over
Walter Mondale that November, at the time the widest electoral-vote margin
in U.S. history. For households, the numbers behind the slogan were
concrete: median income rose to about $22,400, and a gallon of gas cost
$1.13, roughly what it had cost three years earlier even as wages kept
climbing. The contrast with 1980, when 13.5% inflation and interest rates
near 20% had defined the economy, could not have been sharper.
Every 1984 amount converts to 2025 at the same ratio, 3.10: $1,000 becomes
$3,099, and $10,000 becomes $30,986.

Year by year: CPI and the value of $100 from 1984
$100 from 1984 had already become $182 by
2004, on its way to $310 in 2025; 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: 2025
In 2025, prices rose 2.6% and $100 from 1984 had the buying
power of $310; 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.
