Virtual CFO for Gym and Wellness Groups in Sydney (2026)
A virtual CFO for Sydney fitness and wellness groups: membership unit economics, site-level contribution, and the second-studio decision as arithmetic…
A fitness or wellness group lives or dies on two numbers most operators never build properly: what a member is actually worth over their life, and what a site contributes after every cost it carries. Get those right and the second-studio decision becomes arithmetic. Get them wrong and you open a site on optimism and discover the economics eighteen months later. A virtual CFO engagement builds both numbers before the lease is signed.

A single successful studio and a group of studios are different businesses. The single site runs on the founder’s instinct and presence; the group runs on repeatable unit economics, because the founder cannot be everywhere and the second and third sites have to work without them. The transition from one to several is where most fitness groups get into trouble, because the instinct that built the first site does not transfer, and nobody has replaced it with numbers.
The group’s economics rest on membership behaviour and site-level contribution. Members join, pay a recurring fee, and eventually leave; the value of the business is the accumulated contribution of members over their membership lives, less the cost of acquiring them and the fixed cost of the sites they use. That is a unit-economics business dressed as a lifestyle one, and running it well means treating it as the former. This connects to the price of churn, which values what a point of retention is worth, and to designing a multi-site P&L.
Three numbers run a fitness group. The first is average revenue per member per month (ARPM): what a member actually pays, blended across membership types, after discounts and freezes. The second is member churn, the rate at which members leave, usually expressed monthly, which for fitness and wellness commonly sits somewhere in the region of 3 to 6 per cent a month depending on the model and the market, though every operator should measure their own rather than assume. Churn is the single most important number in the business, because a small change in it compounds into a large change in member lifetime and therefore in what the business is worth.
The third is member acquisition cost (CAC): what it costs in marketing and joining incentives to win a member. Put the three together and you have the core of the model: a member worth ARPM a month, staying for a life determined by churn, acquired for a CAC. If the lifetime value comfortably exceeds the acquisition cost, growth funds itself; if not, every new member is a slow loss. The fourth number, sitting above the members, is site contribution: what each studio produces after its own rent, staff, and running costs, before head office. A site can be full of members and still contribute little if its cost base is wrong, which is why site contribution is measured separately from membership.
Take a group with three studios and about $4M in revenue. Blended ARPM is $180 a month. Monthly churn runs at 4 per cent, which implies an average member life of about 25 months (roughly one divided by the churn rate), so a member is worth around $4,500 in revenue over their life before servicing costs. Member CAC, across marketing and joining offers, is $220. On those numbers, a member returns many times their acquisition cost over their life, so acquisition is clearly worth doing, and the constraint on growth is not the economics of a member but the capacity and cost of the sites.
Now the second-studio question, which is really a fourth-site question here. A new studio needs a fit-out (say $450,000) and runs at a loss until its membership ramps to breakeven. The model works out the breakeven membership count (the number of members at $180 ARPM needed to cover the site’s fixed cost) and the months of ramp to reach it, and from those the payback period on the $450,000. If the breakeven is 400 members and the site ramps at 40 net new members a month, it reaches breakeven in about ten months and pays back the fit-out over the following period. That is a fundable, sensible expansion. If the same site would take 400 members but the local market and ramp rate only support 25 net joins a month, breakeven is sixteen months away and the payback stretches uncomfortably, which is the signal to reconsider the site or the model. The numbers, not the enthusiasm, make the call. This is the 90-Day Number at $17,850 plus GST, and you keep the model to run every future site decision.
A fitness group should hire a full-time finance leader when it has grown past what a periodic model can serve: when it is opening sites continuously, managing debt across a portfolio, or running a head office large enough to need daily financial leadership. Below that, a virtual CFO engagement that builds the membership and site models, and hands them over, is the better-value option, because the decisions (which site, when, at what breakeven) are periodic rather than daily. The signals that you have crossed the line are set out in when you have outgrown a virtual CFO.
What are the key numbers for a fitness group?
Average revenue per member per month (ARPM), member churn (which drives member lifetime), member acquisition cost (CAC), and site contribution (what each studio produces after its own costs). The first three define what a member is worth against what they cost to win; the fourth defines whether each site’s cost base works. Together they run the business.
Why does churn matter so much?
Because it compounds into member lifetime, which drives lifetime value. A member churning at 4 per cent a month lasts about 25 months; at 6 per cent, about 17. That difference changes what every member is worth by nearly a third, and therefore what the whole business is worth. Small changes in churn produce large changes in value, which is why it is the single most important number to measure and manage.
How do I decide whether to open another studio?
As arithmetic, not ambition. Model the fit-out cost, the breakeven membership count (members needed to cover the site’s fixed cost), the ramp rate (net new members a month the local market supports), and from those the months to breakeven and the payback period. A site that reaches breakeven quickly and pays back the fit-out in a sensible period is fundable; one that stretches uncomfortably is the signal to reconsider.
What is a good member acquisition cost?
One that is comfortably exceeded by the member’s lifetime value. There is no universal figure, because it depends on your ARPM and churn: a member worth $4,500 over their life easily justifies a $220 CAC, while the same CAC against a member worth $900 does not. The test is the ratio of lifetime value to acquisition cost, not the CAC in isolation.
Do you handle our membership software or bookkeeping?
No. Your membership platform and bookkeeper stay as they are. A virtual CFO uses the data they produce to build the membership economics and site contribution models, the decision layer that tells you what a member is worth and whether the next site works. Running the systems is operational; the CFO layer sits on top.
What does it cost?
A fixed $17,850 plus GST for one named deliverable by day 90, no retainer. The common Australian alternative is an open-ended monthly retainer at $3,000 to $8,000; the project-based model is deliberately different and rare in this market. You keep the model and run future site decisions with it yourself.
What happens after ninety days?
You keep the membership and site models and run them yourself, using them for each expansion decision. There is no default roll-on to a retainer; a further deliverable is scoped separately if needed.
