The Real Cost Per Member of Commercial Cardio Equipment

Key Takeaways:

• Cardio capital should always be divided by the member base that funds it. In the default planning scenario — 12 units at $4,500 installed across 300 members — each member carries $180 of cardio capital.
• Amortization is what turns capital into an operating number: over an 8-year service life, $54,000 of cardio becomes roughly $22.50 per member per year, before maintenance.
• Maintenance is not a rounding error. At 5% of capital per year, a $54,000 cardio fleet adds about $9.00 per member per year to the cost of those machines.
• Break-even has two versions. Covering rent, payroll and utilities is one number; covering the cardio fleet as well is a second, higher number that most operators never calculate.

Cardio Is Usually the Most Expensive Per-Member Category in the Room

Cardio machines are the most visible equipment in a commercial gym and, per member, frequently the most expensive. They cost more per unit than most strength machines, they wear faster because they run loaded for hours a day, they need more clear floor space per unit, and their service parts — belts, decks, bearings, motors, consoles — are consumables with a scheduled replacement rhythm.

None of that appears in the invoice conversation. An operator negotiates a package price, approves it, and moves on. What gets missed is the per-member arithmetic that decides whether the fleet can be carried comfortably or whether it quietly absorbs the margin the business needs.

This tool does that arithmetic. Give it the fleet size, the installed unit cost, the service life, and the member base, and it returns the capital burden per member, the annual cost per member, and the member count required to break even with the cardio fleet in the model.

What “Cost Per Member” Actually Measures

Three different numbers get called “cost per member,” and mixing them up produces decisions that look disciplined but are not.

Capital burden per member is total cardio capital divided by the member base. It answers a single question: how much money each member is effectively carrying. In the default scenario this is $180 per member — a number that matters when membership pricing is being set and when a lender asks how the capital is being recovered.

Annual cost per member converts that capital into an operating figure: annual amortization plus annual maintenance, divided by the member base. This is the number that belongs in a profit-and-loss conversation, because a cash-flow statement does not care about purchase date. In the default scenario it lands at about $31.50 per member per year.

Cost as a share of membership revenue compares the annual cost per member against the revenue each member generates. At a $50 monthly fee, each member generates $600 per year, and the cardio floor absorbs roughly 5% of it. That ratio is the cleanest way to judge whether a fleet is proportionate to the business it serves.

The Three Inputs That Change the Answer Most

Unit cost. Cardio pricing spans a wide range between tier levels and sourcing channels, and the same fleet can be built at very different capital levels. The per-member calculation should use the installed cost — unit price plus freight, rigging, and installation — not the quoted unit price.

Fleet size relative to the member base. This is where cardio planning usually goes wrong in both directions. A 12-unit fleet across 300 members is 4.0 units per 100 members, inside the 2.0-4.5 planning band. A 16-unit fleet across the same base pushes density above the band and adds capital the membership cannot use. A 5-unit fleet leaves members queueing at peak, and queueing members cancel.

Service life and maintenance rate. These two turn a one-time capital number into an annual operating cost, and they are the inputs operators are most likely to estimate generously. A fleet assumed to last 12 years produces a comfortable annual figure; the same fleet at a realistic 7-9 years produces a tighter one. Maintenance is the same story in reverse: 3% of capital per year looks tidy until the fleet is old enough that belt and deck replacement becomes routine.

Reading the Break-Even Output

The tool returns two break-even figures on purpose.

Operating break-even divides fixed monthly costs — rent, payroll, utilities, and everything else that runs regardless of the equipment — by the monthly fee. In the default scenario that is 240 members at $50 per month.

Full-cost break-even adds the monthly recovery of the cardio fleet to those fixed costs before dividing. Cardio recovery in the default scenario is about $787 per month, which moves break-even to roughly 256 members.

The 16-member gap is the honest answer to the question “what does the cardio floor cost us?” It is also the number that disappears from most business plans, because cardio is treated as a one-time purchase rather than a monthly obligation that has to be funded.

Where This Calculation Goes Wrong

Per-member cardio math fails in four predictable ways:

• Using list or retail unit pricing. Commercial cardio purchased through distribution rarely reflects the installed cost of a fleet. Freight, rigging, and installation are part of the capital.
• Planning density from competitor observation. What a nearby club runs is a marketing decision as much as a planning one. Unit count should follow the member base and peak-hour behavior.
• Ignoring maintenance in the operating model. A fleet with no maintenance line in the budget is not a fleet with no maintenance cost; it is a fleet with an unplanned expense.
• Comparing cardio to strength on purchase price alone. This distinction is exactly what separates this page from the category-level comparison in the cardio vs strength ROI analysis, which looks at revenue generation per zone rather than the per-member burden of one fleet.

For a real-world example of what an aging cardio floor does to the operating budget, see the case notes on replacing an entire cardio section after 18 months.

Expert Insight

We recommend modelling the cardio floor per member, not per unit. Per-unit pricing is how cardio gets purchased; per-member cost is how it gets paid for. The two numbers only agree when the member base is known and the fleet density is inside the planning band.

Avoid setting the fleet size from the room’s available wall space. The room determines how many units can physically fit; the member base determines how many units can be carried. Those two limits are rarely the same, and the smaller one wins.

This makes sense when the fleet size, installed unit cost, and expected member base are all available — which is true at any point after the lease is signed and the pricing model is drafted.

This is usually the wrong choice when it is used to justify a fleet that has already been ordered. The number is most useful before the purchase order, while the density and tier decisions are still open.
