Ehsan's Analysis
NRR in e-commerce subscription is almost always below 100% — meaning your installed base shrinks every month. The median DTC subscription NRR is 85-90%, meaning you lose 10-15% of revenue from existing subscribers monthly through cancellations, downgrades, and skipped months. The rare exceptions (Amazon Subscribe & Save at ~105% NRR, Chewy Autoship at ~103%) succeed because they expand wallet share over time: customers add new products to existing subscriptions. The NRR playbook for e-commerce is simple but rarely executed: after month 3 of a subscription, surface a "frequently bought together" recommendation personalized to that customer's consumption pattern. Stitch Fix grew NRR above 100% by expanding box sizes (3 items → 5 items) for satisfied customers, turning a retention problem into an expansion opportunity.
