What one point of churn costs your gym
Put in five of your own numbers to get your monthly churn, average member lifetime, LTV and LTV:CAC, plus what a single percentage point of churn is worth to you over a year. Every output comes from your inputs, and there’s no email gate.
Your numbers
4.5% monthly churn
An average member stays 22.2 months.
Cutting monthly churn by one percentage point is worth about $5,333 a year to you. That is the number worth putting against any retention fix.
- Lifetime value per member
- $1,382
- LTV to CAC ratio
- 11.5:1
- Revenue lost to churn, next 12 months
- $12,960
- Spend to replace them at your CAC
- $25,920
For scale: an AI receptionist at $1,499 pays for itself in 3.4 months if it recovers a single point of churn.
What this does not model
- Seasonality (January joiners and September joiners churn differently)
- Contract length, freezes and minimum terms
- The split between voluntary cancellations and failed payments
- Any benchmark for what “good” looks like in your segment
Where the leak usually is
Four levers, in rough order of leverage
Most churn comes from a handful of identifiable gaps, and most of those are operational.
The first 30 days
The highest-leverage window in the membership, and one many gyms leave to chance. A follow-up from a staff member inside 48 hours and a second visit booked before the first one ends do more than any app feature.
The staff relationship
Whether a member knows a staff member's name by week two predicts whether they stay better than almost anything on your feature list.
Involuntary churn
Failed cards silently lapse memberships nobody decided to cancel. Automatic retries and card-updater support bring back members who never intended to leave.
Missed-visit follow-up
A message after roughly two weeks of no check-in, referencing something specific, works far better than a monthly newsletter, because it responds to what the member stopped doing instead of a date on the calendar.
Methodology
How the numbers are calculated
Monthly churn is cancellations divided by starting members. Average member lifetime in months is the reciprocal of that rate. Lifetime value is the monthly fee multiplied by that lifetime, plus any joining fee. LTV:CAC divides the result by what you told us a member costs to acquire.
The value of one percentage point is the figure worth checking. It takes 1% of your member base and values each of those members at their full remaining lifetime instead of a single month, because a member you keep goes on paying every month.
This page has no benchmarks. Published gym retention averages differ so much between a boutique studio, a 24/7 access gym and a CrossFit box that a single average would mislead more than it helps. Track your own number monthly, ideally by join-date cohort. That usually needs a dashboard from $799 on top of your platform, because built-in reports rarely slice that way.
Before you buy any software to fix retention, check what share of your cancellations were failed payments instead of decisions. If it’s a large share, the fix is in your billing configuration and costs nothing.
FAQ
Gym retention and churn questions
How do you calculate gym member retention rate?
Monthly churn is cancellations in a month divided by the members you started that month with. Retention is the inverse. Average member lifetime in months is the reciprocal of the monthly churn rate, so 4% monthly churn means an average stay of 25 months. The calculator does all three from your own numbers.
What is a good gym retention rate?
It depends so heavily on what kind of gym you run that a single number isn't worth quoting; the methodology section explains why. Your own trend matters more. Track the same calculation monthly, and by join-date cohort if your platform can, so you can tell whether something you changed moved it. An improving rate tells you more than one that merely looks respectable against someone else's benchmark.
Why does one percentage point of churn matter so much?
Because it applies to your whole base every month. A point of churn on 400 members is four people a month who would each have kept paying for their remaining average lifetime. The calculator turns that into an annual figure so you can compare it with the cost of fixing it. Most retention fixes cost three or four figures, and the leak they close is often five.
Should I count failed payments as churn?
Yes, and separately if you can. A meaningful share of member losses are involuntary: a card expires, a payment fails, the membership lapses without anyone deciding anything. It is the cheapest churn to fix, because those members did not choose to leave: automatic retry schedules, card-updater support and a front-desk queue for the stragglers recover a good portion of them without touching programming or facilities.
What is a healthy LTV to CAC ratio for a gym?
As a rough sanity check rather than a rule, a business that spends more to acquire a member than that member is worth is in trouble, and one at parity has no margin to invest in growth. Beyond that, the ratio is most useful for showing direction: if it is falling, either acquisition is getting more expensive or members are leaving sooner, and those two problems have completely different fixes.
