The case earns $64.87 of contribution per active member-month before the fixed roster and premises costs. Cash break-even is 429.6 active members under the stated financing. Compare that requirement with usable capacity and actual demand before treating the format as viable.
Define the unit before comparing margins
The unit is one active member-month with the stated average paid training attachment. The average revenue includes the membership fee plus that small expected training component; it is not a posted all-inclusive subscription price. Contribution deducts payment costs, consumables and the variable training delivery cost before fixed facility staffing.
Contribution and break-even bridge
| Measure | Value |
|---|---|
| Average revenue per active member-month | $71.00 |
| Variable cost per active member-month | $6.13 |
| Contribution per active member-month | $64.87 |
| Mature fixed operating costs / month | $24,827 |
| Scheduled principal + interest / month | $3,039 |
| Operating break-even active members | 382.7 |
| Cash break-even active members | 429.6 |
| Physical/roster capacity active members | 812.5 |
| Mature modeled active members | 650.0 |
Operating break-even equals monthly fixed costs divided by contribution per unit. Cash break-even adds scheduled principal and interest to that numerator. This is a steady-month test; it excludes changes in working capital and does not recover the opening investment.
What limits the number of units you can sell
A membership count must translate into visits. The model uses an assumed share of active members present simultaneously during the peak interval, compared with an assessed usable-occupancy limit. Neither number is a universal gym standard. Validate visit length, peak demand, equipment queues and safe circulation with the actual layout.
Watch the busiest interval as membership grows. Adding off-peak members may be operationally easier than adding members with identical schedules. Reservations, revised hours or a changed equipment mix can alter capacity, but they also change the product promise and may require a new forecast.
| Input | Case assumption |
|---|---|
| Presold active members at opening | 180.0 |
| Gross new joins / month before target is reached | 40.0 |
| Monthly member churn | 4.0% |
| Modeled retained membership target | 650.0 |
| Monthly membership fee | $65 |
| Paid personal-training sessions / member-month | 0.1 |
| Price per personal-training session | $60 |
| Members simultaneously present at peak | 8.0% |
| Paid trainer delivery cost / session | $30 |
| Consumables / member-month | $1 |
| Planning limit on memberships | 850.0 |
| Assumed usable concurrent attendance | 65.0 |
| Payment processing / sales | 3.0% |
The operating dashboard to keep
| Metric | How to measure it | Why it matters |
|---|---|---|
| Opening/closing active members | Beginning members minus cancellations plus successful new joins. | Reconcile membership growth with the billing system. |
| Monthly churn | Cancellations divided by the membership base exposed to cancellation. | Test how many joins only replace departures. |
| Realized monthly receipts | Collected fees after discounts, freezes and failed payments. | Do not forecast from headline list price alone. |
| Acquisition cost per retained member | Sales/marketing spend linked to cohorts that remain active. | Distinguish a cheap trial signup from sustainable membership. |
| Peak concurrent attendance | Observed people and equipment queues in the busiest interval. | Test the operational limit before selling more identical peak-time demand. |
Review these measures with the same service scope and period each time. Investigate changes in price, mix, timing and quality before assuming that a higher revenue total represents an improvement.
Churn changes the replacement workload
Compare monthly exits with joins and peak attendance. Extra acquisition spend may maintain membership without increasing it; training revenue also creates instructor cost.
Contribution and break-even use the stated unit definition. Collect both its numerator and denominator over the same period. Compare the monthly demand scenarios before interpreting a mature-month threshold as an opening-year result.
