Indoor Golf Memberships: Fill Quiet Hours Without Overbooking Prime Time

Start with two calendars

Our example has three bays, open 10 hours a day for 26 days: 780 available bay-hours per month. We designate four hours per open day as peak time: 312 peak hours and 468 off-peak hours. Your busy periods may look different.

List paid public bookings and member bookings separately in each window. Also reserve time for leagues, lessons, maintenance and closures. A monthly total can fit while the evening calendar is full.

To test quiet-hour demand, ask prospective customers about specific times and prices. “Would you join?” is less useful than “Would you book Tuesdays at 11 a.m. for $40 per bay-hour?” Run a small offer with clear terms and track paid bookings, repeat visits and cancellations. Interest alone is weaker evidence than use at the proposed price.

Count dues once, and hours every time

Suppose 40 members each pay $120 monthly and initially use four included hours. That produces $4,800 in dues and occupies 160 bay-hours. The effective collected rate for those member hours is $30. If the same members use six included hours, receipts stay $4,800 but use rises to 240 hours: $20 per member bay-hour.

This is a planning ratio, not an accounting revenue-recognition rule. Use receipts net of refunds and exclude sales tax collected for remittance. Model extra-hour charges separately; our example has none. Do not multiply member hours by the posted public rate and then add dues on top.

In the four-hour case, assume half of member use falls in peak time. Add 200 paid public peak hours at $60 and 60 paid public off-peak hours at $40. Total receipts are $19,200 across 420 occupied hours—$45.71 per occupied bay-hour, even though the peak public price is $60.

Stress-test the promise before making it

Now test a six-hour membership at the same price, with two-thirds of member use requested at peak time. Members request 160 peak hours. Combined with the 200 public peak hours, that requires 360 hours in a 312-hour window.

The following downside assumes all member requests are honored and 48 public peak hours are lost, with no shift to another time. It is one stress case, not a prediction. If customers shift, the result improves; if member requests are denied, test dissatisfaction and cancellations instead.

More occupied hours produce a worse result here because extra included use displaces paid peak bookings. The 5% receipts allowance and $3 usage allowance represent separate costs; do not count the same expense in both. Results exclude debt principal, owner compensation, income tax, capital spending and replacement reserves unless you add them.

Try an off-peak membership, a stated peak-hour allowance, or separately priced peak upgrades. Publish clear booking windows, guest rules, rollover limits and cancellation terms. Model the service you can actually honor; do not assume unused member hours will rescue the economics.

Use the lease total your bank account will feel

In this example, the $16,000 fixed-cost assumption contains $5,500 base rent, $1,200 in assumed common-area, property-tax and building-insurance pass-throughs, $600 in fixed occupancy utilities, and $8,700 in other fixed operating costs. That makes modeled occupancy cost $7,300, not $5,500.

Actual leases allocate expenses differently. Get the proposed lease, current pass-through estimate, reconciliation history where available, utility evidence, rent increases and repair responsibilities in writing. Ask which costs can change and who pays for HVAC replacement. Have your lease adviser review those terms before committing.

Confirm permitted use, occupancy and accessibility requirements with the relevant authorities; verify simulator clearance with the equipment supplier; and obtain buildout, electrical and HVAC quotes. Decide what happens if approvals or construction take longer than expected, including when rent begins.

Keep opening cash separate from operating runway

Deposits, equipment, buildout and opening inventory consume cash before the calendar fills. Estimate those payments first. Then prepare a month-by-month cash schedule for the money left after opening, including debt payments, owner withdrawals and any remaining construction bills.

A separate fictional ramp with monthly net cash changes of −$2,400, −$1,600, −$800 and +$980 reaches a cumulative low of −$4,800 after month three. That requires at least $4,800 of starting operating cash merely to avoid going below zero in that scenario, before any chosen reserve. It is not a recommended reserve amount. A one-month opening delay or additional capital bill can change the answer.

Annual membership cash paid upfront should appear when collected in the cash schedule. It also carries an ongoing access promise. Track future member hours and potential refunds; do not treat all of that cash as free money for expansion.

Your next step: write the membership on one page

Before approving an offer or signing a lease, put these five items together:

1. The promise: dues, included hours, allowed times and booking rules.
2. The calendar: member and public use by daypart, with closures removed.
3. The receipts: dues plus paid bookings, counted once, divided by all occupied hours.
4. The cost evidence: written occupancy and operating quotes, with missing items flagged.
5. The downside: full member use, weaker off-peak bookings and a slower cash ramp.

Expansion operators should also separate new demand from customers moving over from the first location. A full second calendar can still reduce combined profit if it empties the first.

Useful takeaway: approve the membership only after its booking promise fits the peak calendar and its downside fits your cash plan. The number of memberships sold is only part of the decision.

Put the assumptions into a preliminary model

The free calculator provides a simple break-even screen; the sample shows the full plan format. For a first blended estimate, count all occupied bay-hours and use a collected hourly rate that already includes dues. Do not add those same dues again as other revenue. Translate any per-hour costs into an appropriate variable-cost estimate. Keep the separate daypart calendar and detailed cash schedule alongside the model: the tool does not enforce membership rules or model individual bookings.

The $149 automated preliminary assessment uses your inputs to produce three scenarios, weekly booking targets, rent sensitivity, a slow-start stress test and pre-lease checks. Complete the assessment, continue to secure Square payment, and return after confirmation to open and save your plan.

It does not independently verify demand, competitors, property suitability or construction costs, and it is not a lender-grade feasibility study.
