May 2026 CPI: Housing, Tuition, Daycare and Energy Costs

The Bureau of Labor Statistics’ Consumer Price Index for Urban Consumers (CPI-U) shows May 2026 headline annualized inflation at 4.25% and core inflation at 2.85%. The CPI weighting was updated in December 2025. Since 2000 the cumulative change is 99.1% for headline CPI and 89.0% for core CPI.

Among the eight CPI categories, Housing and Medical Care have more than doubled since 2000, each rising over 100%. Food and Beverage and Transportation also rose more than 100% over the same period. Apparel has increased about 6% since 2000 and shows clear seasonal swings. Volatility in the Transportation category is driven largely by the Motor Fuel subcategory.

The BLS does not treat Energy as a standalone expenditure category. The agency publishes an Energy aggregate that combines household energy in the Housing category and motor fuels in Transportation. In the December 2025 weighting, Energy accounts for 6.297% of the CPI basket, roughly 3.4 percentage points for household energy and 2.9 percentage points for transportation fuels. Energy price swings appear in Transportation measures and in prices of goods and services that use energy in production or delivery.

Certain subcategories have risen much faster than the headline index. College Tuition and Fees, which carries a 1.351% weight in the CPI, is up nearly 200% since 2000 on a sticker-price basis; the BLS measure does not subtract grant aid or scholarships. Daycare and Preschool, weighted at 0.699%, has climbed more than 160% since 2000 and accelerated after late 2022 following the end of pandemic-era stabilization grants and tighter labor markets in childcare.

Core CPI excludes food and energy while keeping other household staples and services in the calculation; alcoholic beverages remain included in the core series. Economists and the Federal Reserve commonly reference core CPI to evaluate inflation trends without the short-term volatility of food and energy.

The impact of price changes varies by household. Long-commute families see larger effects from motor fuel price swings than households that use public transit or work remotely. Households with high medical expenses or with tuition and childcare costs face concentrated price increases. Lower-income households and people on fixed incomes spend a larger share of their budgets on food, energy, housing and transportation.

Headline CPI is a weighted average of many goods and services. Individual households experience inflation according to the specific mix of items they buy.
