I’d imagine even a moderately engaged gym user would lose the gym money on every visit, in staffing costs alone. The marginal cost of each user rises too, as people that are unable to get on machine are more likely to churn. It is however usually outweighed by the huge numbers of people who simply do nothing with their subscription.

A gym user attending a gym doesn't incur significant additional staffing costs. The work required to clean the gym may increase a bit but that'd be nowhere near the price of even the cheapest gym memberships.

That's not a cost, it's a factor for the overall churn rate and marginal cost for acquiring a new user. It'd limit the max profitability of a gym (i.e. getting to churn = growth equilibrium) but it's not an operational cost.

But that's not the right way to gauge "cost per member-usage". If you get a lot more usages, you will have to pay noticeably more for staff, maintenance, replacement, etc.

For comparison, how would you gauge the actual cost of sending a letter in the mail? Naively, you would say "well, you can't detect the cost of sending it in labor or fuel costs, so it's zero".

But that would be wrong. The right way is to say "how much would it cost to send a million more letters? The cost of one letter should be treated as one millionth of that" because, in the large, your marginal costs will scale that way as letter transmission goes up and down.

So yeah, the gym is, for all relevant purposes, bearing a small cost each time you use the gym.[1] It's just that, for the vast majority of members, all those usages cost them much less than the membership fee.

In my professional experience with gyms, the most expensive thing you can do, is use the treadmills a lot. They are the most expensive machinery, and most prone to breaking down.

I go to the gym and I interact with 1, sometimes 2 staff members. The people at the front who check my card and sometimes the guy who works in the locker room if I can't get mine open.

They are on staff anyways. It costs them nothing extra.

What is true is that they can understaff (and have less equipment) than if they had 100% regular participation.

The gym I went to before was 24/7 and completely unstaffed outside of daytime hours. When the place was unstaffed, a fingerprint reader was used to verify you were the owner of the card.
