How to Read the CPI Inflation Report
A plain-English guide to headline CPI, core CPI, monthly changes, year-over-year changes, and the limits of one inflation release.
What CPI measures
The Consumer Price Index measures the average change over time in prices paid by urban consumers for a defined basket of goods and services. It is a broad price measure, not a personal receipt for any one household.
The report is useful because it gives a consistent way to compare price changes over time. It cannot tell a reader exactly how their rent, grocery bill, insurance premium, or wage changed.
Monthly versus year-over-year changes
The monthly change compares the index with the prior month. The year-over-year change compares it with the same month one year earlier. Both can matter, but they answer different questions.
A single monthly result can be noisy. Reading the category detail, revisions, and several months of data gives more context than treating one number as a permanent trend.
Headline and core CPI
Headline CPI includes all major categories. Core CPI excludes food and energy to make underlying price patterns easier to compare. Core is not a more real household budget; it is a different analytical measure.
