What do leaving members
actually cost you?

How the figure is worked out

Your annual membership revenue is your active members multiplied by the average monthly fee, times twelve. The cost of churn is the share of those members who leave in a year, valued the same way. It is straight arithmetic on the numbers you entered — there is no benchmark hidden in it and no assumption you did not set yourself.

Treat it as a floor, not a full answer. It counts one year of lost fees. It does not count what those members would have paid in their second and third years, what you spent acquiring them, or the referrals a long-standing member brings that a departing one does not. The real cost is higher, which is rather the point.

Why we will not tell you the industry average

The churn rate above is a slider because we are not going to quote you a figure we cannot stand behind. Numbers circulating online are rarely sourced, and churn varies so widely by program mix, contract length, age group and local market that an average across all of them tells an individual business very little.

There is a more useful reason too. An average cannot tell you where you lose people. Knowing you are at twenty per cent does not tell you whether they leave at month three or month eighteen, which program they were on, or which of them were already slipping before they cancelled. Those answers are only in your own history.

The number worth having instead

A rate is a symptom. What changes decisions is the shape underneath it: how long members last before they go, which intake months held and which did not, and who is thinning out in their first ninety days while there is still time to make a phone call.

That is what Black Belt CRM reads out of the history you already have — and it is the part most platforms do not compute at all. See the retention reports

Questions

What is a membership churn rate?

The share of members who cancel over a period, divided by the number you started with. A raw count of cancellations cannot be compared month to month because it moves with the size of your roster; a rate can. It is the number owners quote to each other, and the one most platforms do not compute.

How do I work out what churn costs my business?

Multiply the members you lose in a year by what each one pays per month, then by twelve. That is the arithmetic this calculator does. It is a floor rather than a full answer, because it does not count what those members would have paid in later years, or what you spent acquiring them.

What is a good churn rate for a gym or studio?

We do not publish one, deliberately. Figures circulating online are rarely sourced, and they vary so widely by program, contract length and market that an average is close to meaningless for any individual business. The number that matters is your own, measured from your own history.

Why does keeping 5% more members matter so much?

Because retained members compound and new ones cost money to acquire. A small improvement in retention lifts revenue every month it holds, without any increase in marketing spend. That is why the calculator shows it as a separate figure.

No. The arithmetic runs in your browser. Nothing is transmitted, nothing is stored, and there is no sign-up to see the result.
