Hi Andrew. Really good questions! In my opinion, the answer to the commission versus rent question depends on a couple of factors. If I’m looking at it from the studio owner’s perspective, by charging a monthly rent you will have a known monthly rental income that you can budget from and make projections on. If you’re the trainer, unless you have a client following that can not only satisfy and justify paying the monthly rental, but also leave you with net income in your pocket, a monthly rental makes little sense.
As for commissions, from the studio owner’s perspective, this system would allow you to attract newer trainers with little following, and allows you and your rental revenue stream to grow along with their business. If attracting trainers to your studio is of little concern, then commission may not be so advantageous. However, with a commission-based system, it is fairer to all concerned since the trainers using the facility more are paying more (similar to the whole rental-space concept of if you were renting studio space, you would expect to pay more rent if you had a larger rental space than other tenants). As a trainer, I would like the commission system because, as I said, it would encourage a newer trainer with a smaller following to sign-on with your studio. One caveat: as the studio owner, the commission system is going to be a lot more difficult to administer since it’s going to require a lot more record-keeping.
I hope this helps.
