Between 1947 and 1980, the Consumer Price Index went from 22.3 to 82.4.
Cumulatively, prices increased 269.5%, which works out to an average of
4.04% per year. Put differently, a dollar in 1947 bought what
$0.27 buys in 1980.
Consumer prices rose 14.4% in 1947, up from 1946’s 8.3% and
the fastest annual increase since 1920, as the last of the wartime price
controls disappeared and a year of strikes, wage catch-up, and lingering
shortages hit consumers all at once. Congress answered the previous year’s
strike wave that June, overriding President Truman’s veto to pass the
Taft-Hartley Act, which banned secondary boycotts and the closed shop and
let states adopt “right-to-work” laws curbing union power. American
attention was also turning outward. In a June 5 speech at Harvard,
Secretary of State George Marshall outlined a U.S.-funded plan to rebuild
Western Europe’s economies, an effort that would become known as the
Marshall Plan once Congress funded it the following year. The government
reorganized itself for the confrontation with the Soviet Union that plan was
partly designed to prevent: the National Security Act, signed July 26,
created the Department of Defense, the Air Force as a separate service, the
Central Intelligence Agency, and the National Security Council. Consumer
prices stood 125.3% above their 1913 level and 30.4% above
1929’s pre-Depression peak, up from just 1.2% above it four
years earlier. First-class postage held at 3 cents, and the minimum wage
stayed at 40 cents an hour.
The headline number is an average. Individual categories moved very differently over this
period. Here is what $100 of 1947 spending costs in 1980, by category:

Not shown because the BLS began these indexes after 1947: core (all items less food & energy) (1957–), energy (1957–), housing (1967–), recreation (1993–), education & communication (1993–).
Long periods are sampled every 2 years; the calculator above covers any pair of years.
The destination year: 1980
1980 sat at the very peak of the Great Inflation. Prices rose 13.5% in that
single year, mortgage rates were climbing toward 16%, and the Federal Reserve
under Paul Volcker was administering the painful interest-rate medicine that
would finally break the inflationary spiral, at the cost of the deep 1981–82
recession. No single year looms larger in how Americans think about inflation.
