PCE belongs to the national accounts#
The PCE price index measures price change for goods and services purchased by or on behalf of people residing in the United States. It includes household spending and relevant expenditures made on behalf of households, making its scope broader in some areas than direct out-of-pocket consumer purchases.
PCE and CPI differ by design#
BEA separates formula, weight, scope, price and residual effects when comparing PCE with CPI. PCE uses a Fisher-Ideal formula that can reflect changing expenditure patterns, while CPI uses a modified Laspeyres formula. Different populations, covered expenditures and source data can therefore produce different inflation rates.
Overall and core PCE are separate views#
Overall PCE includes the full covered set of goods and services. Core PCE excludes food and energy to provide a view less affected by their short-term volatility. Core is not a replacement for the overall index and does not remove the economic importance of food or energy costs.
Read the full Personal Income and Outlays release#
The monthly publication includes personal income, disposable income, consumption expenditures, saving and price indexes. Label monthly and 12-month PCE changes separately, compare overall and core measures, and review whether spending or income estimates changed alongside prices.
Revisions are part of national-account measurement#
BEA can revise recent PCE estimates as more complete source data arrive and can revise longer histories during annual or comprehensive updates. The latest release should be read with revisions to prior months rather than as an isolated value with permanently fixed history.
Federal Reserve use does not create a mechanical signal#
The FOMC states its longer-run inflation objective in terms of the annual change in the PCE price index. That does not mean one overall or core PCE release determines the next policy decision. Officials consider a wider set of inflation, labor, activity and financial evidence, and market reactions remain expectation-dependent.

Key principles#
National-accounts scope
PCE includes spending by households and relevant purchases made on their behalf.
Formula difference
PCE and CPI use different formulas, weights, coverage and source data.
Revision path
Monthly source updates and broader national-account updates can alter history.
Policy limit
The Fed's PCE-based objective does not turn one release into a policy or trading command.
