What happened to prices between 1970 and 2024
Between 1970 and 2024, the Consumer Price Index went from 38.8 to 313.689.
Cumulatively, prices increased 708.5%, which works out to an average of
3.95% per year. Put differently, a dollar in 1970 bought what
$0.12 buys in 2024: the 1970 dollar
lost 87.6% of its purchasing power over
these 54 years.
Consumer prices rose 5.7% in 1970, up from 1969’s 5.5%, extending a
run of faster price growth that stretched back to the mid-1960s, even as a
recession that began in December 1969 pushed unemployment toward 6%. Prices
and joblessness rising together confounded the era’s economic thinking, which
held that policymakers could trade a little more inflation for a little less
unemployment; 1970 was an early sign that trade-off was breaking down, a
pattern that would harden into stagflation later in the decade. Washington
restructured how it delivered mail that year: after postal workers staged the
first strike ever by federal employees that March, Congress passed the Postal
Reorganization Act in August, replacing the cabinet-level Post Office
Department with the independent U.S. Postal Service. Environmental policy
also took shape in 1970. An estimated 20 million Americans marked the first
Earth Day on April 22, and the Environmental Protection Agency opened that
December to enforce the Clean Air Act and the pollution rules that followed.
The Vietnam War kept dividing the country: on May 4, National Guard troops
fired on antiwar demonstrators at Kent State University in Ohio, killing four
students and setting off strikes on hundreds of campuses. A median household
earned $8,734 that year, a gallon of gas averaged 36 cents, and a first-class
stamp cost 6 cents, the rate it had held since 1968. Prices stood 291.9%
above their 1913 level by the end of 1970, a milestone that
would look almost mild against the decade still to come.
Every 1970 amount converts to 2024 at the same ratio, 8.08: $1,000 becomes
$8,085, and $10,000 becomes $80,848.

Year by year: CPI and the value of $100 from 1970
$100 from 1970 had already become $404 by
1996, on its way to $808 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 1970 had the buying
power of $808; 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.
