What happened to prices between 1979 and 2025
Between 1979 and 2025, the Consumer Price Index went from 72.6 to 321.943.
Cumulatively, prices increased 343.4%, which works out to an average of
3.29% per year. Put differently, a dollar in 1979 bought what
$0.23 buys in 2025: the 1979 dollar
lost 77.4% of its purchasing power over
these 46 years.
Consumer prices rose 11.3% in 1979, the fastest pace since 1947 and the
decade’s second bout of double-digit inflation after 1974’s
11.0%. The trigger was familiar: the Iranian Revolution that January halted
Iran’s oil exports, and panic buying amplified the shortage, sending crude
prices sharply higher over the year and motorists back into gas lines, with
some states reviving the odd-even rationing last seen in 1974. Paul Volcker,
appointed Federal Reserve chairman that August, responded with a strategy
shift announced that October: the Fed would target the money supply directly
and let interest rates rise as high as necessary to break inflation, whatever
the short-term cost. That cost would arrive as a deep recession in 1981-82,
but by year’s end 1979 had already delivered enough turmoil on its own. A
reactor at the Three Mile Island plant near Harrisburg, Pennsylvania,
suffered a partial core meltdown that March 28, the worst commercial nuclear
accident in U.S. history, and on November 4, militants in Tehran stormed the
U.S. embassy and took 52 Americans hostage, beginning a 444-day crisis that
consumed the rest of Carter’s presidency. A median household earned $16,461
in 1979, a new home sold for a median $62,900, and gas jumped to 86 cents a
gallon. Consumer prices finished the decade 97.8% above where they stood in
1969, very nearly doubling in ten years, and stood 633.3%
above their 1913 level. The 1970s had opened with inflation
cooling from the 1969 spike and closed with prices rising faster than at any
point since 1947, setting up the Great
Inflation’s final act in 1980.
Every 1979 amount converts to 2025 at the same ratio, 4.43: $1,000 becomes
$4,434, and $10,000 becomes $44,345.

Year by year: CPI and the value of $100 from 1979
$100 from 1979 had already become $244 by
2001, on its way to $443 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 1979 had the buying
power of $443; 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.
