Another consideration is the modality. I live in S. FLA and here Yoga and Aquatic instructors get paid on average 20% greater than other group instructors. Commercial gyms typically pay less too. However, as a manager the more I allow an instructor to make~the better instructors I get. Then the bigger the class gets and everyone earns more.
Just a consideration…
Danny it really depends on where and what kind of class you are starting. I personally started my own Bootcamp at my local park. I contacted the county parks and was given the go ahead to use the park space at no cost (no overhead). I currently reside about 20 mins south of Atlanta. In the first year attendance was a struggle and averaged about $12 per hour. As I continued marketing and providing perks and bring a friend deals within 2 years we grew substantially. I am currently in my 3rd year of our BootCamp and average about 40 participants per class. My average hourly has gone up to around $83 per hour. Like with anything in this field the time and effort will reap rewards.
