Gym Financial Plan: Projections That Hold Up

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.

Build revenue from capacity, not from a growth rate

Evidence note: SBA recommends explained financial projections, five-year outlooks, and quarterly or monthly first-year detail. SBA does not establish that 10% is a common gym error or that 18 months is the correct horizon. Use evidence-based assumptions, explain them, and choose a horizon matching the financing and operating decision. Sources: Plan your business - Small Business Administration.

Build it from the floor up instead:

• Classes per week your schedule actually runs
• Evidence note: The displayed capacity identity is arithmetically coherent for class-based revenue and gives an upper bound under stated assumptions. Fill, attendance, price, schedule, appointment, PT, and capacity definitions can differ; no universal forecasting standard is cited. Show the formula, define every input, and model appointment and PT capacity separately. Source status: No primary source was found for the earlier universal claim as of 2026-09-01.
• × realistic fill rate — not 100%, and not your best class

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.

The capacity ceiling

Here's the number lenders notice is missing, and the one that changes decisions.

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.

Enrolment ramp, month by month

You do not open full. Plans that show month-one revenue at steady state are the fastest way to lose a reader.

Churn is your most sensitive input

Evidence note: Include a reproducible sensitivity table showing churn, acquisition, price, capacity, and cash effects. No model, baseline, membership mix, pricing, or sensitivity table is provided to substantiate the comparison. Source status: No primary source was found for the earlier universal claim as of 2026-09-01.

Break-even, with a date

Evidence note: SBA recommends income statements, balance sheets, cash-flow projections, expense detail, and funding sufficient to cover operating needs. The formula depends on contribution and fixed-cost definitions, and SBA does not establish the article’s “most common failure” claim. Retain the statement as planning guidance and show assumptions and cash-flow timing. Sources: Plan your business - Small Business Administration; Manage your business - Small Business Administration.

Add a cushion for the things that slip: build-out overruns, a delayed occupancy permit, a slower ramp than modelled.

Model seasonality honestly

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.

What lenders and landlords actually test

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.

Keep the plan alive after you open

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.

Features are vendor-authored and available by plan; illustrative dashboard numbers are not independent outcomes and forecasts are not guarantees. Date the feature statement, identify plan availability, and separate product capability from financial results. Sources: Mako first-party: Mako Financial Planning and CFO Tools.
