Annual averages of the Consumer Price Index for All Urban Consumers, 1982–84 = 100, published by the U.S. Bureau of Labor Statistics. 2026 has no annual average yet, so it uses August 2026, the latest month published.

What got more expensive

The headline rate averages things that behaved nothing like each other. Categories are published as annual averages only, so this compares 1980 with 2025, the last complete year.

Each category is measured against itself over the same years. The indices use different base periods, so their levels are not comparable with each other — only their changes are, which is all this shows. Not shown, because BLS began the series later than 1980: recreation (from 1993), education and communication (from 1993).

  • Note: Based on CPI-U: 82.4 (1980 annual average) and 334.98 (August 2026, the latest month published), 1982–84 = 100.

Every row is the 1980 amount multiplied by the same ratio: CPI-U of 334.980 in August 2026 divided by 82.400, the 1980 annual average — 4.0653. Put the other way, a dollar today buys what $0.25 bought in 1980.

The first row is 1980 itself, where $100 is still $100. Each later row is that year’s CPI-U divided by 82.400, multiplied by $100 — the same arithmetic as the calculator above, applied once a year.

What got more expensive since 1980

The headline figure above averages things that moved very differently. Medical care and housing have outrun the index for decades; clothing has barely moved. If inflation has never matched your own experience, this is why — your basket is not the average basket.

What this cannot tell you

CPI is a national average, and your own prices will differ. Housing, healthcare and education have risen much faster than the index as a whole, and some goods — electronics above all — have become far cheaper.

It does not capture regional differences. A dollar in 1980 went further in some places than others, and still does.

The basket itself has changed. People in 1980 did not buy what people buy now, so the ratio is exact arithmetic on a comparison that is looser than a single number suggests.

August 2026 is one month, not a year. Monthly figures carry some seasonal movement, so this headline shifts slightly each month until BLS publishes the full-year average.
