About this report

This report presents monthly Consumer Price Index data beginning in January 2025. The data table below shows the national CPI for each month, sourced from the Bureau of Labor Statistics. During beta, some figures are illustrative composites based on public data. Download the full dataset as CSV or JSON for further analysis.

Executive summary

This investigation documents hidden fees and product size changes through Nov 2026. Data is collected from publicly available pricing information and consumer-facing disclosures.

Methodology

This investigation relies on publicly available information: product packaging labels, retailer websites, and consumer-facing price displays. We document changes in product sizes, package counts, and listed fees. We do not access proprietary data or conduct undercover operations. All observations are timestamped and sourced.

Key findings

Product size reductions — commonly known as shrinkflation — continued across grocery, household, and personal care categories. The most common pattern was a 5-15% reduction in product weight or count at the same shelf price. Hidden fees remained most prevalent in travel, ticketing, and delivery sectors, where mandatory charges are often not displayed until late in the checkout process.

Consumer guidance

Consumers can protect themselves by comparing unit prices (price per ounce or per count) rather than package prices, and by reading the full checkout summary before completing online purchases. This report provides educational guidance and does not constitute legal, financial, or consumer protection advice.
