Customer retention rate

Customer retention rate is the share of customers you had at the start of a period who are still customers at the end of it, excluding any new customers acquired during the period. It is the complement of logo churn, and like churn it is meaningless without a stated cohort and time window.

How it is calculated

Take customers at the end of the period, subtract those acquired during the period, divide by customers at the start. Excluding new acquisitions is the step most often skipped, and skipping it lets growth mask retention.

Why it matters

Retention compounds. A business retaining a high share of customers can grow on a modest acquisition rate, while one with weak retention has to acquire faster every period just to stay level — which shows up as rising acquisition cost rather than as a retention problem.

Where retention problems originate

Often in acquisition rather than in service. Accounts sold on a use case the product serves badly churn on schedule regardless of how good the follow-up is, which makes qualification one of the cheapest retention investments available.

How Autocloz handles it

Autocloz reports activity and pipeline against accounts on one shared timeline, so accounts that have gone quiet are visible as a list rather than something someone has to remember to check. It does not model subscription billing, so retention accounting itself belongs in your billing system.

FAQ

How do you calculate customer retention rate?

Customers at the end of the period, minus customers acquired during the period, divided by customers at the start of the period. Excluding new acquisitions is essential — including them lets growth hide a retention problem.

Is retention rate the same as the opposite of churn?

For logos, yes: retention and churn sum to the whole. For revenue they diverge, because expansion within retained accounts can offset revenue lost elsewhere, which is why net revenue retention can exceed one hundred percent.
