That's not an easy question to answer. First of all it depends, are you an independent contractor? Here an IC rents space and runs their own classes/schedules/curriculum, and pay their own insurances. They charge according to their expenses, the studio/studio owner can not tell them how do do things, and can not be involved with their classes including collecting fees from the IC students. They are under self employment. On the other hand, I own my business and have my own studio.
I hire employees. Now, as far as what I offer them for a wage is based on all my expenses of running the business, rent, utilities, licencing, water, sewage, garbage, office supplies, classroom supplies, cleaning supplies, cost of equipment(mats, poles,etc.), liability teaching insurance, commercial property insurance, unemployment insurance premiums, workers comp premiums, etc. After all the expenses of running the business are totaled, that helps determine what hourly wage I pay them. They either accept and work, or they decline and go elsewhere. I provide insurance for all my employees, and ongoing training.
The pay scale depends on their experience and amount of training, and which level of pole they are teaching. I'm afraid I'm not much help. Every area is different due to cost of living, demographics, etc. :)
