Well, much of this is relative, was kinda part of my point. As well, if one is self-employed as opposed to be an employee, this makes a major difference.
I still vaguely remember moving from Corporate society to self-employed...and never looked back, tho I used to love working in the Corporate world.
It depends a lot, of course, on the type of business also. I have known people whose profit margins are so large they can give out lavish gifts and parties for their employees, take large bonuses, and have a merry old time.
Then others who have to watch how every little cent is spent.
I seem to recall, and also think I am misremembering, and don't feel like looking it up, that a business should shoot for a 40% profit over 60% CODB, roughly...tho that would depend on the business...feel free to correct me.
