Using customer data science to measure the "Loyalty Lift" and identify structural risks in shopper behavior.
At a Glance
$108M Total Incremental Revenue (Best + New Segments)
60% Higher Annual Spend from Loyalty vs. Non-Loyalty
27% Gap in New Loyalty Member Acquisition (Key Risk)
The Challenge
The objective was to isolate the true incremental value of the Loyalty Program. By comparing Loyalty Members against a representative Non-Loyalty baseline, the business sought to identify which segments were driving genuine growth and where the program faced long-term structural risks.
The Action
We applied a "Lift" methodology across two primary levers:
Acquisition & Retention: Measuring the gap in "Shop Rates" between Loyalty and Non-Loyalty groups.
Basket Growth: Calculating the difference in net spend per shopper.
The Results
The analysis highlighted a strong "Loyalty Lift" in spend, but also revealed critical vulnerabilities in the customer pipeline:
The "Best" Customer Engine: Loyalty Members in the "Best" segment delivered $77.5M in incremental spend. These shoppers visit more often and spend more per visit than their non-loyalty counterparts.
The Spend Premium: Even in the "New" customer segment, a Loyalty Member spends $122 more on average than a Non-Loyalty shopper.
Key Strategic Risks
While the program drives high value, the data identifies three primary risks to long-term sustainability:
1. The $27M Acquisition Gap (Critical Risk)
There is a -27.4% gap in the shop rate of New Loyalty Members compared to the Non-Loyalty base. The program is failing to "hook" new shoppers at the market rate, creating a long-term risk to the customer pipeline.
2. Concentration Risk
Total program success is heavily reliant on the "Best" segment. Because the "New" and "Next Best" segments are not growing at the same rate, the business is over-exposed to the behavior of a small, elite group of shoppers.
3. Margin Erosion & Subsidy
Loyalty Members receive average discounts of 28-29%, compared to 24-25% for non-members. There is a risk that the program is subsidizing shoppers who would have purchased anyway, or training them to wait for deep promotions.
Strategic Recommendation
To mitigate these risks, the program should pivot from "deep discounting" for existing members toward "acquisition incentives" for new shoppers to close the 27% shop-rate gap.
