What happened to prices between 1971 and 2024
Between 1971 and 2024, the Consumer Price Index went from 40.5 to 313.689.
Cumulatively, prices increased 674.5%, which works out to an average of
3.94% per year. Put differently, a dollar in 1971 bought what
$0.13 buys in 2024: the 1971 dollar
lost 87.1% of its purchasing power over
these 53 years.
Consumer prices rose 4.4% in 1971, down from 1970’s 5.7% as
the recession that started in December 1969 finally cooled demand. The bigger
economic story came that August 15, when President Nixon closed the “gold
window” that let foreign governments exchange dollars for gold, ending the
Bretton Woods system that had anchored the dollar since World War II. The
same address announced a 90-day freeze on wages and prices, the first
peacetime controls the country had seen, an attempt to break inflationary
expectations without the slower grind of tighter money. The “Nixon Shock,” as
it came to be known, let the dollar float against other currencies for the
first time and set the stage for a wage-and-price-control regime that would
run in various forms into 1973. Politically, the country lowered its voting
age that year: the 26th Amendment, ratified July 1, extended the vote to
18-year-olds, capping a campaign built on the argument that men old enough to
be drafted to Vietnam were old enough to vote for the people who sent them.
The Postal Service, independent since 1970’s reorganization, raised
first-class postage from 6 to 8 cents that May. A median household earned
$9,028 in 1971, up from $8,734 the year before, while gas held near 36 cents
a gallon and a new home sold for a median $25,200. Consumer prices stood
309.1% above their 1913 level by year’s end, still years away
from the double-digit inflation the controls were meant to prevent.
Every 1971 amount converts to 2024 at the same ratio, 7.75: $1,000 becomes
$7,745, and $10,000 becomes $77,454.

Year by year: CPI and the value of $100 from 1971
$100 from 1971 had already become $396 by
1997, on its way to $775 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 1971 had the buying
power of $775; 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.
