What counts as retained is clear for subscriptions and arbitrary for almost everything else.
Subscription businesses
A customer either has an active subscription or does not, which makes retention observable and comparison meaningful within the model.
Even here, downgrades and pauses complicate a binary reading.
Repeat purchase businesses
A customer who bought in January and not since may be lapsed or may buy annually, and only an arbitrary window distinguishes them.
The window choice determines the retention figure entirely, and it is set differently by different businesses.
Occasional purchase categories
Where the natural purchase interval is years, retention as usually measured is close to meaningless.
Repeat purchase rate over a longer horizon is the more honest measure here.
The measurement period
Monthly and annual retention figures describe the same customers and produce very different numbers, and both are quoted as retention.
Comparing across periods without converting is a common and substantial error.
Revenue rather than customer retention
Retaining a customer whose spend halved is retention by one measure and a substantial loss by another.
Revenue retention alongside customer retention describes the situation where either alone misleads.
