A good gym attrition rate is 2 to 3% of members lost per month. Most independent gyms run at 5 to 8%, and many owners have never calculated theirs at all. This article shows you how to measure attrition properly, what the benchmarks are, and the three fixes that reliably bring it down.
Those benchmarks come from the Gym Owner Network: 500+ gyms mentored across 16 countries, most running or moving to a small group personal training model. We track attrition across the network every month, because it's the single most honest number in a gym business.
What is gym attrition and how do you calculate it?
Gym attrition is the percentage of your members who leave each month. Calculate it by dividing members lost by total members at the start of the month. Lost 6 members from 120? That's 5%. Same day every month, same method, no exceptions.
Two rules to keep the number honest:
Count everyone who stopped paying. Cancellations, freezes that never return, quiet non-renewals. If the direct debit stopped, they left. Owners soften this number instinctively. Don't.
Track it monthly, not annually. Annual figures hide the bleed. A gym can tell itself "we keep most members" while losing 6% a month, which is more than half the member base over a year.
If you've been winging your numbers and you're a little scared to look at the bank, this is the number to start with. Clarity is kindness, including with yourself.
What is a normal attrition rate for a gym?
Across the independent gym market, 5 to 8% monthly attrition is common. Across the GON network, well-run small group gyms hold 2 to 3%. The gap between those two figures is mostly model and coaching ratio, not luck or postcode.
Here's what each level means in practice:
- 2 to 3% monthly: healthy. Roughly a third of your membership turns over per year. Referrals can largely replace it.
- 4 to 5% monthly: leaking. Half your gym turns over yearly. Marketing spend is partly going to replacement, not growth.
- 6%+ monthly: the bucket has a hole. Growth is mathematically painful: every new member is cancelling out a leaver.
Average member lifespan is the same number from the other side. At GON network gyms, members stay 18+ months on average, against an industry standard of around 9. Double the lifespan means double the lifetime value of every member you sign, before you spend a penny more on marketing.
The outlier that shows the ceiling: MARCHON, the performance gym founded by GON co-founder Ollie Marchon, has run attrition as low as 1%.
Why do gym members actually leave?
Members leave when they stop being seen. Price and life admin are the reasons on the cancellation form. The reason underneath, in most cases, is that nobody noticed them drifting: attendance slipped, progress stalled, and no one said anything until the cancellation email arrived.
This is where the coaching ratio stops being a philosophy and starts being a retention system. In a session capped at six, the coach knows every member's programme, mood, and attendance pattern. A missing member is visible the day they go missing. At 1:12 or 1:15, the quiet ones are invisible by design.
So before blaming the market, run the diagnostic upstream, the way we do in mentorship:
- Is it a visibility problem? Do you know, today, which members haven't attended in 10+ days? If not, attrition isn't your problem. Tracking is.
- Is it a product problem? Are specific sessions, coaches, or times leaking more than others? The data usually points somewhere specific.
- Is it a pricing-handled-badly problem? A price rise done without notice or context spikes attrition. The rise is rarely the mistake. The delivery is. Here's how to raise prices without losing members.
How to fix a high attrition rate
The fixes are unglamorous and they work. Three moves, in order:
1. Build the going-quiet alarm. Track attendance weekly. Any member absent 10 to 14 days gets a personal message from their coach, not a marketing email. Human, specific, about them. Most drifting members come back when someone notices early. None come back once they've decided.
2. Put progress in front of members. People stay where they can see themselves winning. Reviews every 8 to 12 weeks, measurable markers, and coaches trained to connect today's session to the member's goal. In a small group model this is structurally easy, because every member already has an individual programme to review against.
3. Fix the ratio if the ratio is the leak. If your sessions have crept to ten or twelve people, retention work is patching a product problem. Members in oversized "small group" sessions are paying attention-level prices for class-level attention, and they can feel it. Capping at six costs spots on the timetable and buys you years of member lifespan. See the full comparison: SGPT vs group classes.
What we'd tell you not to do: launch a retention "campaign." Discounts for staying, loyalty points, win-back offers. These treat the symptom, teach members that leaving triggers rewards, and change nothing about why people drift.
Frequently asked questions
What is a good attrition rate for a gym?
2 to 3% of members lost per month. That's the standard well-run small group gyms hold across the GON network. Above 5%, treat it as the business's most urgent problem.
What's the difference between attrition and churn?
Nothing meaningful. Both describe members leaving as a percentage of the base. Pick one word, one formula, and track it the same way every month.
How long does the average gym member stay?
Around 9 months across the independent gym industry. GON network gyms average 18+ months. Coaching ratio, individual programming, and early intervention on drifting members drive the difference.
Does raising prices increase attrition?
Done badly, yes, briefly. Done properly, after the product visibly improved, with straight communication and notice, the effect is far smaller than owners fear, and revenue per member rises enough that a small loss still nets positive.
High attrition is a structure problem, not a market problem
Your town didn't get less loyal. Your members aren't flakier than members were five years ago. Somewhere between the ratio, the tracking, and the member journey, the structure is leaking, and structure is fixable.
