To give you an idea, I think at my current rates I'd need about 30-40 students to break even on equipment costs, insurance, rent, etc. Since I can only reasonably do about 25 students in a class, and would expect two classes per student per week, I'd need 4 classes to even break even. That's the max number of classes I can currently offer, so break-even is really my end game. I've been using cheap equipment and free space, and in a year I've made no personal income from my program. Granted, my current program is VERY small, but costs add up fast. Just my cheapo mats (which may last another 6-12 months) cost me about $1,000 and some hours of personal time to make them more usable.I am not saying many instructors are making a living on it. I am saying it is hard to believe most of the instructors are not making some money (=making money out, right?). And I said I know people (and I know very little) living on it as extreme examples.
In my first month teaching, I was making money for my organisation and for me (50/50) with a few students. (Ok, all my earnings I put back on my own training and equipment, fuel... but it was from the first month.) So how to believe people in the market for decades and/or dozens of student don't make some money?
Ok, I put a lot of money and time on my own training before having some earnings. But after decades still not making some money overall? You don't know no one making some money, really?
Ok, you may say it is like this. I will not argue more about that. It is since a while no more about 'requirements to open a dojo'. Perhaps about 'requirements to keep the door open'... New thread to come?
