The Consumer Price Index for All Urban Consumers: All Items in U.S. City Average (CPIAUCSL) was 327.460 in Feb. and 326.588 in Jan. Since 327.460/326.5881 = 1.00267, that means it was up 0.267%. If we had that every month for 12 months it would be up 3.25%. 

It was 319.679 in Feb. 2025. Since 327.460/319.679 = 1.0243, that means it was up 2.43% over the last 12 months.

The non-seasonally adjusted CPI was 326.785 in Feb. and 319.082 in Feb. 2025. That was up 2.41%. 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 2.8% higher in Jan. 2026 than Jan. 2025).

For more information see Consumer prices rose 2.4% annually in February, as expected by Jeff Cox of CNBC. Excerpt:

"Prices consumers pay for a broad range of goods and services rose in line with expectations for February, offering a final look at inflation pressures before an oil shock tied to the Iran war rattled the outlook.

The consumer price index increased a seasonally adjusted 0.3% for the month, putting the 12-month inflation rate at 2.4%, according to Bureau of Labor Statistics data released Wednesday. Both numbers matched the Dow Jones consensus forecast.

Stripping out volatile food and energy prices, the core CPI posted a 0.2% monthly reading and 2.5% annual rate, compared with forecasts for 0.2% and 2.5%, also in line with the estimates.

The annual rates were unchanged from January, indicating that inflation was holding above the Federal Reserve’s 2% target but not getting worse.

While the report showed inflation broadly stable, prices rose modestly for shelter and services while several goods categories, including used vehicles and auto insurance, saw declines."

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.
