What happened to prices between 1916 and 1986
Between 1916 and 1986, the Consumer Price Index went from 10.9 to 109.6.
Cumulatively, prices increased 905.5%, which works out to an average of
3.35% per year. Put differently, a dollar in 1916 bought what
$0.10 buys in 1986: the 1916 dollar
lost 90.1% of its purchasing power over
these 70 years.
1916 was when World War I first showed up clearly in American price tags.
Consumer prices rose 7.9% for the year, easily the sharpest increase since
the Bureau of Labor Statistics’ CPI history begins in 1913, as factories ran
flat out to fill steel, munitions, and food orders from Britain and France.
Railroad workers felt the squeeze from rising living costs enough to threaten
a nationwide strike; Congress headed it off in September with the Adamson
Act, which set an eight-hour standard workday for interstate rail employees,
the first federal law of its kind covering private-sector hours. Washington
was also preparing more directly for war: the National Defense Act, signed
in June, expanded the Army and National Guard and funded new
government-owned munitions plants, adding another source of demand to an
economy already running hot. Woodrow Wilson won re-election in November
largely on having kept the country out of the fighting so far, a promise
that would not survive the following spring. A first-class stamp still cost
2 cents, one of the few prices that had not yet moved.
Every 1916 amount converts to 1986 at the same ratio, 10.06: $1,000 becomes
$10,055, and $10,000 becomes $100,550.

Year by year: CPI and the value of $100 from 1916
$100 from 1916 had already become $239 by
1951, on its way to $1,006 in 1986; each row shows the CPI, that
year's inflation rate, and the running value.
Within the span, inflation peaked at 18.0% in 1918, and prices fell 10.5% in 1921, the deepest deflation of the period.
Long periods are sampled every 5 years; the calculator above covers any pair of years.
The destination year: 1986
In 1986, prices rose 1.9% and $100 from 1916 had the buying
power of $1,006; the year's average CPI of 109.6 is the level
behind every 1986 figure on this page.
1986 delivered the decade’s biggest one-year drop in inflation, and it came
almost entirely from a single source: oil. Saudi Arabia abandoned its policy
of restraining output to prop up prices, and world crude collapsed from
about $27 a barrel to under $10 by midyear. Gasoline, which had averaged
$1.12 a gallon in 1985, fell to 86 cents. With energy costs plunging,
headline CPI inflation for the year came in at just 1.9%, the lowest annual
rate since 1965 and a striking bookend to 1980’s 13.5% peak. The relief was
uneven: prices for most goods and services outside energy kept rising at a
moderate pace, so households that didn’t drive much or heat with oil felt
less of the difference. In October, Congress passed the Tax Reform Act of
1986, a bipartisan overhaul that cut the top individual income tax rate from
50% to 28% while closing many deductions and shelters, the broadest rewrite
of the federal tax code since World War II. Between cheap gas and falling
interest rates, 1986 read like proof that the inflationary 1970s were a
closed chapter, six years after the U.S. economy had felt anything but
calm.
