A gym financial plan needs five things a business-plan template usually skips: a revenue model built from capacity rather than a growth percentage, a month-by-month enrolment ramp, a break-even date you can defend, an explicit churn assumption, and enough working capital to reach that date — and the capacity number is the one almost every plan omits.
If you've already written the narrative sections and stalled on the spreadsheet, this is the part that decides whether anyone funds it.
The most common failure is a revenue line that grows 10% a month because 10% seemed reasonable.
Build it from the floor up instead:
That gives you a weekly ceiling. Everything in your projection has to sit under it.
For an appointment or PT-led model, substitute trainer hours available × utilisation × rate. Same logic: the constraint is delivery, not demand.
Here's the number lenders notice is missing, and the one that changes decisions.
Your revenue has a hard maximum: classes × spots × fill × price. Most plans project growth straight through it without ever stating what it is. If your ceiling is $38,000 a month and month 14 of your projection shows $46,000, the plan is not optimistic — it's wrong, and it's wrong in a way that's obvious to anyone who checks.
State the ceiling explicitly, then show what you'd do to raise it: add classes, add a room, add trainers, raise price. That turns an omission into a growth plan.
It's also the honest way to size the business. A single-room studio has an arithmetic limit, and knowing it early tells you whether the model works before you sign a lease.
You do not open full. Plans that show month-one revenue at steady state are the fastest way to lose a reader.
Model the ramp explicitly: presales before opening, the first-month surge, the month-three dip when the initial cohort's novelty wears off, and the slower compounding after. Show the numbers monthly for at least the first 18 months — annual averages hide exactly the period where you run out of money.
Change your churn assumption by two percentage points and your year-three revenue moves more than almost any other variable. It deserves to be stated, not buried.
Put it in the plan as an explicit number with a rationale, then show what happens at a worse rate. A plan that says "we assume 5% monthly churn, and here's the model at 8%" reads as competent. A plan with no churn line reads as untested.
This matters operationally too, not just on paper. The gap between 5% and 8% monthly churn is the difference between a business that compounds and one that runs on an acquisition treadmill — we've written about the arithmetic of retention separately.
Break-even is not a ratio, it's a month. Fixed costs — rent, insurance, base staffing, software, utilities, loan servicing — divided by contribution per member, gives the member count you need. The ramp tells you when you reach it.
Then answer the question that follows: how much cash do you need to survive until that month? That's your working capital requirement, and underestimating it is the most common reason otherwise-viable gyms fail. It belongs in the funding ask, not as an afterthought.
Add a cushion for the things that slip: build-out overruns, a delayed occupancy permit, a slower ramp than modelled.
January is not a typical month. Neither is July.
If your model averages the year, it will show a comfortable cash position that never exists in reality. Show the January surge, the spring attrition, the summer trough. Lenders who know the category will look for it, and its absence signals you haven't run one of these before.
Whoever reads this will check the same handful of things: whether the revenue build is bottom-up, whether the assumptions are stated rather than implied, whether the cash-flow statement ever goes negative, and whether you've asked for enough money.
The U.S. Small Business Administration publishes a standard business-plan and financial-projection structure worth matching, simply because it's the format most readers already expect. Familiar structure means they spend their attention on your numbers rather than on finding them.
Include all three statements — profit and loss, cash flow, and balance sheet. Profit and loss alone is the most common gap, and cash flow is where gyms actually die: you can be profitable on paper in month nine and still be unable to make payroll in month seven.
The plan's real value starts on opening day, when you can compare it to what's happening.
That only works if you can see actuals at the same granularity you modelled — revenue by class, cost per class, contribution per member, churn by month. Most operators find this out the hard way: the model is monthly and detailed, the accounting is quarterly and aggregate, and the two never meet.
Mako reports profit and loss, cash flow, and margin per class in real time rather than at quarter-end, which is what makes the comparison possible at all. If you built the plan bottom-up from capacity, you can check it against reality the same way.
For the full plan structure around these numbers, see our guide to writing a gym business plan. If you're opening a specialist facility, gymnastics business plans have their own constraints.
