Try this out.  Find a martial artist who has been training for at least three years.  Ask them how many years of experience they have in the martial arts.  Then ask them if they would take $100,000 in exchange for all the knowledge, experience, skill, and fitness they gained from the martial arts.  If they say, "no", up the offer.  Offer $500,000, then $1,000,000.  When you find a price high enough that they take you up on your offer divide that total by the number of years of experience, then divide by 12.  You now have a dollar amount that shows what their martial arts training was worth to them.  

Personally I wouldn't take $10,000,000 for mine.

At that rate, classes would cost $33,333.33 per month.
