The
Consumer Price Index for All Urban Consumers: All Items in U.S. City
Average (CPIAUCSL) was 323.364 in Aug. and 324.368 in Sept.
Since 324.368/323.364 = 1.003105, that
means it was up 0.3105%. If we
had
that every month for 12 months it would be up 3.79%.
It was 314.851 in Sept. 2024. Since 324.368/314.851 = 1.0302, that means it was up 3.02% over the last 12 months.
The
non-seasonally adjusted CPI was 324.800 in Aug. and 315.301 in Aug.
2024. That was up 3.01%. 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 2.7% higher in Aug. 2025 than Aug. 2024).
“Prices that people pay for a variety of goods and services rose less
than expected in September, according to a Bureau of Labor Statistics
report Friday that keeps the door wide open for another interest rate
cut next week.The consumer price index
showed a 0.3% increase on the month, putting the annual inflation rate
at 3%. Economists surveyed by Dow Jones had been looking for readings of
0.4% and 3.1%, respectively. The annual rate reflected a 0.1 percentage
point uptick from August.
Excluding
food and energy, core CPI showed a 0.2% monthly gain and an annual rate
also at 3%, compared with estimates of 0.3% and 3.1%, respectively.
Core CPI on a monthly basis had posted 0.3% gains in both July and
August.”
The article also discusses what types of products are going up in price and what is going down. There is a graph of the monthly year-over-year percent change in prices and core prices going back almost 4 years.
and is not seasonally adjusted. It is also the December to December
change in the CPI. That site also looks at how the 12 month average for
the CPI changed from one year to the next.
