Retention Metrics
Churn, Repeat Rate, and Retention Rate Are Not the Same Number
MechanicMembers earn rewards or status through repeat purchases, subscriptions, or engagement; tiers or benefits unlock as cumulative activity crosses thresholds.
CostThe member pays with money, personal data, attention, or the opportunity cost of choosing this program over alternatives.
RewardPoints, discounts, freebies, exclusive access, or tier-based perks that increase perceived value with continued participation.
Retention metrics are the backbone of any loyalty program, but they are often conflated.

Cohort Analysis: Why a Blended Retention Number Hides the Problem
MechanicCohort analysis groups members by join date or first purchase, then tracks each group's retention over time to reveal how loyalty mechanics, tier design, or subscription terms perform across different member vintages.
CostThe member pays the standard price for goods or services, plus the ongoing effort of participating in the program, such as carrying a card, logging in, or maintaining a subscription.
RewardPoints, discounts, free items, tier status, or subscription benefits that the member receives in exchange for repeat engagement.
A blended retention number is the average of all members active in a given period, regardless of when they joined.

Measuring Retention Without Confusing Correlation With Loyalty
MechanicA loyalty program that tracks member behavior over time and uses control groups or holdout segments to separate true retention effects from selection bias and natural repeat purchasing.
CostThe member gives up purchase data, attention, and sometimes a small fee or enrollment step; the business forgoes margin on rewards and invests in measurement infrastructure.
RewardPoints, discounts, free shipping, exclusive access, or tier-based perks that are intended to increase the likelihood of a repeat purchase or renewal.
Retention programs are often judged by how many members come back.

The Time Window That Makes or Breaks a Retention Metric
MechanicA time-window retention metric tracks whether a member returns within a defined period after a key event such as a purchase, reward redemption, or subscription renewal. The window is set by the business and becomes the pass/fail test for retention.
CostThe member gives up time and attention to return within the window, and may also spend money or effort on a purchase or engagement to stay active.
RewardThe member receives a tangible or intangible benefit for returning in time, such as points, a discount, access to a tier, or continued subscription service.
A retention metric is only as useful as the time window attached to it.
