What Is Core PCE? How the Fed’s Inflation Gauge Works

Core PCE, short for Core Personal Consumption Expenditures, is the inflation measure the Federal Reserve watches most closely. It tracks the average change in prices across a wide range of goods and services American households consume, with food and energy stripped out to reveal the underlying trend. The Fed adopted it as its preferred inflation gauge in 2000 and, in January 2012, formally set its 2% inflation target in terms of the PCE price index.1Board of Governors of the Federal Reserve System. Federal Reserve Issues FOMC Statement of Longer-Run Goals and Monetary Policy Strategy Every interest rate decision runs through this number.

What the PCE Index Measures

The Personal Consumption Expenditures Price Index is compiled by the Bureau of Economic Analysis as part of the GDP calculation. It captures roughly two-thirds of all domestic final spending in the United States.2Bureau of Economic Analysis. NIPA Handbook Chapter 5 Personal Consumption Expenditures

The basket is broad. Durable goods like cars and appliances. Non-durable goods like clothing and groceries. Services from healthcare to legal advice. And unlike some inflation measures, PCE doesn’t stop at what households pay out of pocket. It also counts spending made on consumers’ behalf, including employer-provided health insurance, Medicare, and Medicaid.3Federal Reserve Bank of Cleveland. Infographic on Inflation: CPI versus PCE Price Index That inclusion is a big reason healthcare carries more weight in the PCE than it does in other inflation gauges.

The index also uses a Fisher-Ideal formula, which continuously updates the weights of items in the basket to reflect how people actually shift their buying when prices change.4Bureau of Labor Statistics. Differences Between the Consumer Price Index and the Personal Consumption Expenditures Price Index When beef gets expensive and shoppers switch to chicken, the formula reflects that. Fixed-basket measures don’t, which tends to overstate inflation over time.

What “Core” Adds

The difference between headline PCE and Core PCE is simple: Core PCE excludes food and energy prices.5U.S. Bureau of Economic Analysis. Personal Consumption Expenditures Price Index, Excluding Food and Energy

Those two categories swing hard. A drought spikes grocery bills. A geopolitical crisis sends gasoline up 20% in a month. These shocks are real, and families feel them, but they’re usually temporary and driven by forces disconnected from the broader economy’s health. Filter them out and what remains is a slower-moving picture of price pressures building across the rest of consumer spending: services, housing, manufactured goods, medical care.

That’s the signal policymakers want. A gasoline spike shouldn’t dictate a rate hike that takes months to work through the economy. Persistent price growth across services and goods probably should.

Why the Federal Reserve Cares

Congress gave the Fed a dual mandate in a 1977 amendment to the Federal Reserve Act: maximum employment and stable prices.6Board of Governors of the Federal Reserve System. The Dual Mandate and the Balance of Risks “Stable prices” is defined operationally as 2% annual growth in the PCE price index, and Core PCE is the version Fed officials watch most closely to gauge whether that trend is on track.

In August 2020, the Fed adopted flexible average inflation targeting. Under this framework, after a stretch when inflation has run persistently below 2%, the Fed will aim for inflation moderately above 2% for a while so the average returns to target.7Board of Governors of the Federal Reserve System. The Federal Reserve’s New Framework: Context and Consequences The 2% goal didn’t change. The willingness to tolerate temporary overshoots did. Core PCE remained the yardstick.

As of the March 2026 FOMC meeting, the median projection among Fed officials puts Core PCE inflation at 2.7% for the year, with individual estimates ranging from 2.2% to 3.0%.8Board of Governors of the Federal Reserve System. Summary of Economic Projections, March 18, 2026 That’s still above target, and each monthly release is read against that gap.

How Core PCE Differs From the CPI

Most people encounter inflation through the Consumer Price Index, published by the Bureau of Labor Statistics. CPI and PCE cover similar ground but consistently produce different readings, for three reasons.

The first is scope. CPI measures only out-of-pocket spending by urban households. PCE covers all households and includes spending done on their behalf by employers and government programs.3Federal Reserve Bank of Cleveland. Infographic on Inflation: CPI versus PCE Price Index Healthcare is the clearest example: CPI captures what you pay at the doctor’s office, while PCE also counts what your insurer, employer plan, or Medicare paid on your behalf.

The second is how heavily housing counts. Shelter makes up roughly 35% of CPI, giving rent and home prices an outsized pull on the headline. Housing’s share of PCE is significantly smaller because PCE covers a wider range of spending.3Federal Reserve Bank of Cleveland. Infographic on Inflation: CPI versus PCE Price Index

The third is the formula. CPI uses a Laspeyres formula with a relatively fixed basket. PCE uses the Fisher-Ideal formula that adjusts for consumer substitution.9U.S. Bureau of Economic Analysis. What Accounts for the Differences in the PCE Price Index and the Consumer Price Index The combined effect: PCE inflation tends to read slightly lower than CPI inflation over time.

What Core PCE Doesn’t Tell You

The exclusion of food and energy is a blunt instrument. Research from the Federal Reserve Bank of Dallas found that some food and energy components are actually stable and carry useful signal, while some non-food, non-energy items are highly volatile and add noise Core PCE doesn’t filter out. From 2005 through 2019, quarterly headline PCE inflation averaged 1.77%, while Core PCE averaged 1.61%. A trimmed mean PCE, which removes whatever items are most volatile in a given month regardless of category, averaged 1.78% and tracked headline inflation more closely.10Federal Reserve Bank of Dallas. Which Core to Believe? Trimmed Mean Versus Ex-Food-and-Energy Inflation

There’s also a simpler point. People buy food and gasoline. Households spending a large share of income on groceries and fuel feel inflation Core PCE isn’t designed to reflect. The measure was never meant to describe any individual family’s cost of living. It’s a policy tool built to help central bankers see through short-term price swings, and it should be read that way.

Where To Find the Number

The BEA publishes Core PCE monthly as part of its Personal Income and Outlays report, typically about four weeks after the reference month ends.11U.S. Bureau of Economic Analysis. Personal Income and Outlays, January 2026 Both month-over-month and year-over-year figures are available directly on the BEA’s website.5U.S. Bureau of Economic Analysis. Personal Consumption Expenditures Price Index, Excluding Food and Energy

The year-over-year number is the one that drives headlines. It compares the current month’s index level to the same month a year earlier, smoothing seasonal patterns and giving a clearer read on sustained inflation. When a news report says “Core PCE came in at 2.8%,” that’s almost always the annual figure. The month-over-month number is useful for spotting emerging trends but bounces around more and gets less weight from policymakers.
