What is churn?

The rate at which customers or subscribers stop using a service.

In plain English

Churn measures how many customers leave in a period, as a percentage of those you had. Five per cent monthly churn means you lose about half your customers over a year.

It is the most consequential number in any recurring business, because it works against everything acquisition achieves. Growth is acquisition minus churn, and churn compounds silently.

What to know

Compounding makes it brutal
Reducing monthly churn from five per cent to three transforms lifetime value and the economics of acquisition.
Early churn is a fit problem
Customers leaving in the first weeks usually mean the promise and the product did not match, which is a marketing issue.
Later churn is a value problem
Long-standing customers leave when the value stops being felt or a need changes. Different cause, different fix.
Ask the leavers
Cancellation is the most honest research opportunity you get. Most businesses waste it entirely.

Why it matters

Cutting churn is usually cheaper than raising acquisition and improves every other number at once. Lifetime value rises, payback shortens, and the acquisition you can afford increases. It is the least glamorous growth lever and often the largest.

Common mistakes

×Tracking new signups closely and churn occasionally.
×Treating all churn as one problem rather than separating early from late.
×Never asking departing customers why they left.
×Overselling in marketing, which produces customers who leave quickly.

FAQs

What is a good churn rate?

It depends on price point and market, but lower is always better and small improvements compound significantly.

How do I reduce churn?

Fix the onboarding for early churn, and make continuing value visible for later churn. Ask leavers what happened.
