What is Churn Rate?
Churn rate is the percentage of paying members who cancel within a period, calculated as cancellations divided by the number of subscribers at the start of that period.

How churn is calculated
Churn = cancellations / subscribers at the start of the period, usually measured monthly. A membership that starts the month with 1,200 subscribers and loses 42 has a monthly churn of 3.5%. Two variants matter: customer churn counts people, revenue churn counts money, and the two diverge when cancellations skew towards your cheapest or your most expensive plan. Report whichever you use consistently, and say which one it is, because a membership can hold customers while losing revenue.
Why churn sets your ceiling
Churn, not recruiting, decides how large a membership can become. At a steady rate, membership plateaus near monthly signups divided by churn rate. Adding 40 members a month at 8% monthly churn stabilises around 500 members however hard you promote; halving churn to 4% lets the same recruiting support 1,000. That is the whole argument for spending a week on retention rather than a week on launches, and it is also why MRR read without churn beside it tells you nothing about next year. Our creator revenue calculators run the plateau arithmetic on your own numbers.
Voluntary and involuntary
A cancellation and a failed payment look the same in the total and need opposite responses. Voluntary churn is someone deciding to leave, and the fix is in the product: onboarding, the first week's value, whether drip content keeps arriving. Involuntary churn is an expired or declined card, and the fix is mechanical: payment retries, card-update emails and a dunning sequence before access is cut. Split the two in your reporting before you act on either, because improving a product to solve what turns out to be an expired-card problem wastes the quarter.
Where the number lives
The platform taking the payment is the only source that sees refunds, declines and mid-cycle cancellations, so read churn there rather than in a spreadsheet. Circle lists Professional at $89 per month, checked 6 October 2026, and Skool lists Hobby at $9 per month and Pro at $99 per month, checked 1 October 2026; both report recurring revenue and cancellations, and they differ in how much of the retention tooling, such as retry logic and win-back emails, is included rather than bolted on. The Circle and Skool comparison covers that split, and the course and membership platforms category lists the alternatives.
Frequently asked questions
What is a good churn rate?
We publish no figure, because churn depends on price, commitment length and whether the purchase is discretionary, and the honest comparisons are against your own previous months. The useful test is the plateau: divide your monthly signups by your churn rate and ask whether the resulting membership size is the business you want.
What does a 20% churn rate mean?
One in five paying members cancelled during the period, usually a month. On 1,000 members that is 200 cancellations, and at a steady rate the membership plateaus at five times monthly signups. It also means the average member stays about five months, so acquisition cost has five months to pay back.
What is the difference between customer churn and revenue churn?
Customer churn counts members who left; revenue churn counts the recurring money that left with them. Losing ten $9 members and losing one $90 member are the same revenue churn and ten times the customer churn. Track both, because the gap tells you which plan is leaking.
Can you reduce churn without changing the product?
Partly. Involuntary churn from failed payments responds to card-retry logic, update reminders and a dunning sequence, none of which touch the product. Voluntary churn does not: it responds to onboarding, to whether the first week delivers something, and to having a reason to log in next month.
