CHICAGO, Jan. 09, 2026 (GLOBE NEWSWIRE) — Numerator, a data and technology company providing insights into consumer behavior, released its December 2025 Numerator Consumer Price Index (CPI) with an advance read on inflation trends across everyday consumer goods. According to Numerator, prices for everyday household purchases increased 0.29% in December, following a 0.36% increase in November and a 0.04% increase in October. In December, prices for everyday goods are up 2.4% versus a year ago.
Similar to the U.S. Bureau of Economic Analysis’ Personal Consumption Expenditures (PCE) price index, the Numerator CPI tracks prices and changes in consumer purchases over time. The data cover approximately 20% of the consumption basket captured in the overall PCE price index, and closely tracks the PCE Food & Beverage index, offering a reliable signal of retail price changes experienced by U.S. consumers.
“Everyday goods inflation remains elevated at roughly 2% to 2.5% annually,” said Paul Stanley, Senior Economist, Numerator. “Because these categories represent frequent, essential purchases, consumers continue to feel the impact of persistently high prices even as monthly changes are moderate.”
Additional key findings from Numerator’s December CPI:
- Prices for everyday household goods increased 0.29% month over month in December, following a 0.36% increase in November and a 0.04% increase in October.
- Prices for everyday household goods are up 2.4% year over year.
- Following November’s nine-month low of 2.2%, inflation ticked up in December to 2.4% growth vs. year ago, ending a trend of three consecutive months of slowing year-over-year price increases.

METHODOLOGY
Numerator’s consumer inflation measure is constructed using both base-period and current-period quantity weights to combine item prices, an approach that is consistent with the structure of the U.S. Bureau of Economic Analysis’ PCE Price Index.
The index is calculated from verified, item-level transactions provided by a panel of 200,000 geographically and demographically representative U.S. households. These data include purchases across categories such as grocery, household goods, and health and beauty. The data capture changes in consumer purchasing behavior when prices change, including brand switching, downsizing, and shifts in where consumers buy.
Values are aggregated monthly to produce index levels and month-over-month and year-over-year percent changes, providing a current view of inflation trends. The dataset uses verified household purchase data from the demand side, offering visibility into consumer behavior as prices evolve.
The Numerator CPI’s year-over-year inflation measure has a 0.93 correlation with the PCE Food and Beverage index since 2019.
