What this number cannot tell you
- The index is the consumer price index for all urban consumers (CPI-U), all items, U.S. city average, not seasonally adjusted. It follows what a basket of goods and services bought in cities costs; it is not a record of what any one household paid for any one thing.
- 1987 is taken at the annual average of its monthly indexes. One dollar of September 2026 is that month's index alone, so the value of a dollar moves when the Bureau publishes a new month.
- The yearly rate, the highest and lowest rates, the steps and the value of a dollar are our arithmetic on the Bureau's index values. The Bureau does not publish or endorse them.
- The Bureau prints its index to one decimal for the early years and to three for the later ones. The sums use the digits as printed.
