See Consumer Price Index for All Urban Consumers: All Items in U.S. City Average from FRED (Federal Reserve Economic Data) compiled by the Research Division at the Federal Reserve Bank of St. Louis for data on the seasonally adjusted CPI.  

That site shows a graph but if you click on the Download button you will get the actual numbers in Microsoft Excel.

The Consumer Price Index for All Urban Consumers: All Items in U.S. City Average (CPIAUCSL) was 333.979 in May and 332.568 in June. Since 332.568/333.979 = 0.99578, that means it was down 0.422% since 1 - .99578 = 0.422. If we had that every month for 12 months the CPI would be down 4.95%. 

 

It was 321.435 in June 2025. Since 332.568/321.435 = 1.0346, that means it was up 3.46% over the last 12 months.

The non-seasonally adjusted CPI was 333.952 in June and 322.561 in June 2025. That was up 3.53%. So pretty close to the seasonally adjusted CPI. This is well above the Fed's target of 2.0% (although they prefer to use the Personal Consumption Expenditures Price Index which was 4.1% higher in May 2026 than May 2025).

 

For more information see Consumer prices rose 3.5% annually in June, less than expected as energy prices eased by Jeff Cox of CNBC. Excerpt: 

"Consumer prices posted their biggest decline in more than six years during June as a sharp swoon in energy prices provided at least temporary relief from this year’s inflation surge, the Bureau of Labor Statistics reported Tuesday.

The consumer price index, a broad measure of costs for goods and services across the U.S. economy, was lower than expected across the board. The CPI fell a seasonally adjusted 0.4% for the month, bringing the annual inflation rate down to 3.5%."

 "Core inflation, which excludes food and energy, was flat on the month, putting the 12-month rate at 2.6%. The consensus forecast was for respective increases of 0.2% and 2.9%, following a 2.9% May level."

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.
