What did the September 2026 figure show?

If you buy everyday goods and services in the United States, prices in September 2026 were 3.7% higher than in September 2025. This figure is the consumer price index for all urban consumers, known as CPI-U. It is a 12-month change, so it compares one month with the same month a year earlier.

Sources for this paragraph (1)

Is that higher or lower than the month before?

It is higher. In August 2026, the same 12-month measure stood at 3.4%. The September rate was 0.3 percentage points above that.

Sources for this paragraph (3)

This is a change in the yearly rate, not a monthly price change. It means the gap between prices now and prices a year ago widened from August to September. It does not tell us how much prices moved within September alone.

What do the separate price categories show?

Each category below is its own statistic, and each is a 12-month change for September 2026. They are listed one by one rather than ranked against each other or against the overall rate.

What does this mean for people living in the United States?

For a typical US household, the basket of goods and services tracked by the CPI-U cost 3.7% more in September 2026 than it did a year before. That yearly increase was larger than the one recorded for August 2026.

Sources for this paragraph (2)

Your own experience depends on what you buy. The official figures give a separate yearly change for energy, motor fuel, food and shelter. You can match those categories to your own spending, but the data here does not show how any particular household was affected.

Sources for this paragraph (4)

What can't these figures tell us?

The facts here do not explain why prices rose. They do not show price changes from one month to the next, differences between regions, or differences between income groups.

Sources for this paragraph (2)

The category figures come from separate series. This report does not set them against one another or against the headline rate, so it cannot say which category drove the overall change.

Sources for this paragraph (4)

One more month of data is not a trend. Two readings, August and September 2026, show a rise in the yearly rate, but they cannot show where it goes next.

Scenarios to watch

  • Scenario, not a forecast If the October 2026 CPI-U release shows a 12-month rate above September's, it would suggest the yearly rise in prices kept widening for another month.
  • Scenario, not a forecast If the October 2026 12-month rate comes in at or below September's, the September increase may have been a single-month step rather than the start of a run.
  • Scenario, not a forecast If the energy and motor fuel series show smaller yearly changes in coming releases, those categories would be adding less to household costs than they did in September 2026.

What to check next

  • The October 2026 CPI-U 12-month change, compared with the 3.7% recorded for September 2026
  • Whether the energy and motor fuel 12-month changes rise or fall in the next release
  • The shelter and food 12-month changes, which cover large parts of household budgets
  • Month-over-month CPI figures, which show price moves within a single month
