Consumer spending is the value of goods and services bought by or on behalf of U.S. residents. It is the largest component of U.S. gross domestic product (GDP), so changes in inflation-adjusted spending contribute to measured economic growth. But a rise in the dollars households spend does not necessarily mean they are buying more: prices may have risen faster than spending.
What is consumer spending?
The Bureau of Economic Analysis (BEA) calls consumer spending personal consumption expenditures (PCE): the value of goods and services purchased by, or on behalf of, U.S. residents. The phrase “on behalf of” matters. PCE can include an insurer’s payment toward a patient’s hospital bill, not only the amount a household pays directly. BEA defines and reports consumer spending.
PCE covers household consumption across goods and services and is part of the expenditure approach to GDP. It is not the same statistic as the Bureau of Labor Statistics’ (BLS) average consumer-unit expenditures. PCE is a national-account measure of spending in the U.S. economy; BLS’s figure comes from a household survey and describes average spending by a “consumer unit,” a survey category for people who make spending decisions together. The two measures answer related but different questions.
How does consumer spending affect the economy?
GDP measures the value of final goods and services produced in the United States. In the expenditure approach, it combines PCE with private investment, government spending, and net exports. When inflation-adjusted PCE rises, it adds to measured GDP growth, all else equal. The other components, imports, price adjustments, and later data revisions also matter, so PCE’s contribution is an accounting result—not proof that consumer spending alone caused a particular growth outcome.

In BEA’s third estimate for 2024, PCE represented 67.9% of current-dollar GDP and contributed 1.87 percentage points to real GDP growth. Real GDP grew 2.8% that year. The 67.9% figure is a share of GDP measured in current dollars; the 1.87 percentage-point figure is PCE’s contribution to the change in real GDP. They are different measures and should not be read interchangeably. BEA’s April 2, 2025, third-estimate analysis reports these figures.
That large share helps explain why consumer spending is watched as an indicator of economic activity. The BEA describes spending by consumers, including spending on their behalf, as a major force in national economic growth and publishes PCE data as part of its regular releases. BEA’s consumer-spending explainer describes the measure and its uses.

Why can spending rise while households buy less?
Nominal spending is the number of dollars spent at current prices. Real spending adjusts for price changes to estimate the amount of goods and services those dollars buy. If prices climb faster than outlays, nominal spending can increase even as real spending falls.
BLS illustrates the distinction with its 2024 consumer-unit data: average annual expenditures were $78,535, up 1.8% in nominal terms from 2023. Average consumer-unit inflation was 2.9%, and BLS calculated that real spending declined 1.1%. These are survey-based averages for consumer units, not aggregate BEA PCE. BLS’s 2024 consumer-expenditure report provides the figures and methodology.
For any monthly or annual spending report, check whether the change is in current dollars or inflation-adjusted dollars, and note the period and data vintage. BEA revises national-account estimates as more complete information becomes available, so a previously reported growth rate may change.
What happens when consumers spend less?
If real PCE declines while the other GDP components stay unchanged, it subtracts from measured GDP growth. In practice, other components can also rise or fall, and the effect on total GDP depends on how they move. A decline in nominal spending alone is not enough to establish that households are buying fewer goods and services; prices may have changed too. Look at real PCE to assess the inflation-adjusted change in consumption.
Rank #4
The available GDP and household-spending figures describe measured spending and its contribution; they do not by themselves quantify how debt, saving, or income distribution changes the economy-wide effect. Avoid treating one household’s choices, or a single spending release, as a complete explanation of economic growth.

Not automatically. PCE is used both to measure consumption in the national accounts and, through the PCE price index, to measure inflation. Those roles are related but distinct: a spending total describes outlays, while a price index tracks changes in prices. The figures here establish how spending and inflation are measured, not a standalone causal estimate of how much consumer spending produces inflation.

The Federal Reserve’s longer-run inflation objective is 2%, measured by the annual change in the PCE price index. CPI is another widely used inflation measure, but it is a different index and is not the Fed’s stated target measure. The Fed notes that PCE adapts more quickly to changes in consumer spending patterns than CPI. Any comparison should identify the index and time period. The Federal Reserve explains its PCE inflation measure.
