Understanding the chained CPI-U for all items

Where it stands today

The chained CPI-U for all items was 186.755 in September 2026.

What does the chained CPI-U for all items measure?

The chained consumer price index for all urban consumers (C-CPI-U) follows the prices of the same households as the CPI-U, with a different formula. The Bureau of Labor Statistics (BLS) uses the Tornqvist formula, which takes the spending of two neighbouring periods into account, so that the index shows the shifts households make between items when their prices change. BLS publishes it each month with the CPI, for the U.S. city average, as an index set to 100 for December 1999.

What this number cannot tell you

  • BLS issues the C-CPI-U first in a preliminary form, because the spending data it needs come later, and revises it. The final index is published 10 to 12 months after the first estimate, so the newest months can change.
  • The series begins in December 1999 and BLS does not calculate earlier periods. It is not seasonally adjusted.
  • BLS did not collect October 2025 because of the lapse in appropriations. The month has no value and is a gap in the chart.
  • The index is shown to three decimals, as the BLS file has it; a value with fewer places is shown with zeros. The changes and the highest and lowest values are ours, worked out from the published values.
