What happened to prices between 1970 and 2014
Between 1970 and 2014, the Consumer Price Index went from 38.8 to 236.736.
Cumulatively, prices increased 510.1%, which works out to an average of
4.20% per year. Put differently, a dollar in 1970 bought what
$0.16 buys in 2014: the 1970 dollar
lost 83.6% of its purchasing power over
these 44 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 2014 at the same ratio, 6.10: $1,000 becomes
$6,101, and $10,000 becomes $61,014.

Year by year: CPI and the value of $100 from 1970
$100 from 1970 had already become $362 by
1992, on its way to $610 in 2014; 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: 2014
In 2014, prices rose 1.6% and $100 from 1970 had the buying
power of $610; the year's average CPI of 236.736 is the level
behind every 2014 figure on this page.
2014 ended with the sharpest oil price drop in years. Consumer prices rose
1.6% for the year, close to 2013’s pace, but the annual figure hid a shift at
the pump: crude oil fell from above $100 a barrel in June to below $60 in
December, and gasoline finished the year near $2.25 a gallon after averaging
$3.37 across 2014. The drop reflected record U.S. shale output, softer
global demand, and OPEC’s decision in November to keep producing.
For households, cheaper fuel arrived just as the labor market strengthened.
Median household income was $53,657, essentially flat on the prior year, and
the median new home sold for about $288,500. The federal minimum wage stayed
at $7.25 for a fifth year, and a first-class stamp rose to 49 cents.
The Federal Reserve ended its bond purchases in October but left its policy
rate at zero. A stronger dollar helped hold down import prices. Because
energy weighs heavily in the CPI, the late-year slide carried into 2015, which
posted the smallest annual increase of the decade.
