The Consumer Price Index for All Urban Consumers: All Items in U.S. City Average (CPIAUCSL) was 315.454 in Oct. and 314.686 in Sept. Since 315.454/314.686 = 1.00244, that means it was up 0.244% (news stories are rounding this off to 0.2%). If we had that every month for 12 months it would be up 2.96%.

It was 307.531 in Oct. 2023. Since 315.454/307.531 = 1.02576, that means it was up 2.576% over the last 12 months (news stories round this to 2.6%).

In the last 6 months it is up just 0.717%. If we had that for 12 months it would be up 1.44%.

The non-seasonally adjusted CPI was 315.664 in Oct. and 307.671 in Oct. 2023. That was up 2.60%. So pretty close to the seasonally adjusted CPI. This is still above the Fed's target of 2.0% (although they prefer to use the Personal Consumption Expenditures Price Index which was 2.1% higher in Sep. 2024 than Sep. 2023). 

For more information, see Annual inflation rate hit 2.6% in October, meeting expectations by Jeff Cox of CNBC. Excerpts:

"Inflation perked up in October though pretty much in line with Wall Street expectations, the Bureau of Labor Statistics reported Wednesday.

The consumer price index, which measures costs across a spectrum of goods and services, increased 0.2% for the month. That took the 12-month inflation rate to 2.6%, up 0.2 percentage point from September.

The readings were both in line with the Dow Jones estimates.

Excluding food and energy, the move was even more pronounced. Core CPI accelerated 0.3% for the month and was at 3.3% annually, also meeting forecasts."

The article also discusses what is going up and what is going on. There is a graph of the monthly year-over-year percent change in prices and core prices going back almost 3 years.
