Eighth annual Retailer Preference Index (RPI) for U.S. Grocery

Since its inception in 2017, dunnhumby’s Retailer Preference Index (RPI) has been a key resource for U.S. retailers and brands, surveying over 10,000 shoppers annually to track customer preferences across 60+ grocery retailers. The latest RPI offers vital insights into the factors driving customer loyalty, with an emphasis on price, promotions, and rewards—key pillars for long-term success in an increasingly competitive market.

With projected slow grocery sales growth in 2024, the report highlights the importance of balancing quality and savings, especially as consumer focus shifts toward price sensitivity. The RPI methodology uniquely blends financial data and customer perceptions, providing actionable insights for retailers to improve their value propositions and competitive standing. The findings reveal that top-ranking retailers, such as H-E-B, Market Basket, and Aldi, are growing significantly faster than their lower-ranked competitors, who often struggle with value differentiation.
