If you have 250 students do you really need a book to tell you how to make money???
Any moron can make money from 250 students without sacrificing costs. Its called economies of scale. The average cost incurred per student gets less as the number of students increase. Why? Because fixed costs such as rent get spread over a large number of students. So when you had 40 students charging them 100 each you payed 50 into costs so 50 remained for you. The costs change by very little with every new student but the money you get is still 100. Eventually you will get 100 from each student but only pay 20 for each student, leaving you with 80. If you do some correct cost planning with expanion (more instructors more salaries etc etc) you can also afford to start advertising more heavily.
Its not a secret formula for gods sake.
All that is required is someone with the right knowledge about cost and profits, you dont even need the right knowledge just some experience, and a business model that you intend to follow.
The most important thing is getting the venue (dojo), after that its all down to quality teaching and word of mouth and advertising. Not some crappy business formula. I bet you anything, I can tell you all the stuff the book says, but just dressed with less fancy crap. You have to remember the guy who wrote the book didnt write it to help all the poor dojo owners, he wrote it to make money!
So, yes there are strategies that you can pursue without sacrificing quality, but they should be quite obvious. All that is required is to sit down withsomeone who has a head for maths and calculate osts and expenditures.
Dude X has 20 students each paying 100 per month.
(in reality you have to include sales of gi's and camps and whatever else you do)
That means revenue of 2,000 a month
say rent and electricity is fixed at 1,000 a month.
That means that you are making yourself 1,000 a month.
Which is not that much to live with.
From salary that you take out a loan for 10,000
5,000 is spent on advertising and 5,000 on paying the salary of a new instructor for the next 5 months.
Say that through the advertising you get an influx of another 20 students immediately on the first day of the new month (highly unrealistic but good enough for our purpose)
From those 20 students you get the fee of the 100 and therefore make 2,000 on what you made before. But you dont have any extra costs. so you get 3,000 a month now.
1,000 for you, 1,000 for the extra instructor and 1,000 to go towards paying back the loan.
You still have the 5,000 left because you got the influx of the students through the advertising and therefore payed the new instroctur through that. So with that 5,000 you can split it into two, 2,500 goes to a new add campaign, not with some better targeting, and 2,500 goes towardsarranging some more classes for the future, some extra equipment to deal with the student influx etc.
You see from the EXTREMELY simplified model above that it really isnt that hard to do it yourself if you re4ally wanted to. In more cases though people want to teach to transmit the art not to get loads of money therefore people feel the need to educate sifu wiht small basement dojos. When in fact they themeselves dont care about the money, and the sifus who do care about the money dont need to buy the book to be successfull at what they do.
Basically, all those books are a poor excuse for not attending a simple accountancy course. There are so many variables that a book could not possibly cover all that is there. What if you have a venue, what if you want to buy one, what if you are renting and want to buy one, what if you ahve nothing, what if you have summer camps twice a year, what if you want to keep the ration of instructors to students high, what if equipment involves shipping stuff from china or japan. What if this and that. Those books that claim to provide formulas are crap, WHY? BECAUSE THEY DONT KNOW THE VARIABLES, SO HOW CAN THEY KNOW THE FORMULA???
