What happened to prices between 1990 and 2021
Between 1990 and 2021, the Consumer Price Index went from 130.7 to 270.97.
Cumulatively, prices increased 107.3%, which works out to an average of
2.38% per year. Put differently, a dollar in 1990 bought what
$0.48 buys in 2021: the 1990 dollar
lost 51.8% of its purchasing power over
these 31 years.
In 1990, the median U.S. household earned about $29,900, gas averaged $1.15 a
gallon, and mailing a letter cost a quarter. Inflation ran hot at 5.4% for the
year, its highest rate since 1982, pushed up by an oil shock after Iraq’s
invasion of Kuwait, and the economy tipped into recession that summer. It was
the last gasp of elevated inflation before the long calm of the 1990s.
Every 1990 amount converts to 2021 at the same ratio, 2.07: $1,000 becomes
$2,073, and $10,000 becomes $20,732.

Year by year: CPI and the value of $100 from 1990
$100 from 1990 had already become $154 by
2006, on its way to $207 in 2021; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 4.7% in 2021, 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: 2021
In 2021, prices rose 4.7% and $100 from 1990 had the buying
power of $207; the year's average CPI of 270.97 is the level
behind every 2021 figure on this page.
2021 was the year inflation stopped being background noise. Consumer prices
rose 4.7% on average for the year, and the pace kept building as the months
went on: by December, the 12-month rate had reached 7.0%, the highest since
1982. The proximate cause was a supply chain that could not keep up with a
fast-reopening economy. A global semiconductor shortage choked new car
production and pushed used vehicle prices up by more than a third, the
single largest line item in the year’s inflation math. Lumber, appliances,
and shipping capacity told versions of the same story: demand snapped back
faster than factories, ports, and truckers could handle it. Washington added
fuel in March with the $1.9 trillion American Rescue Plan, on top of the
relief already in the pipeline since 2020. For most of the year, the Federal
Reserve called the price surge “transitory,” a temporary reopening effect
expected to fade on its own, and held its policy rate near zero. By
November, with inflation still climbing, the Fed reversed course and began
winding down its bond purchases, the first step toward the rate hikes that
would follow in 2022. Gas averaged $3.01 a gallon for the year, up from
about $2.17 in 2020, while the federal minimum wage held at $7.25,
unchanged since 2009. In hindsight, 2021 reads as the hinge year: the point
where “transitory” inflation became the multi-year fight the Fed spent the
next two years trying to win.
