If you are a contractor and not an employee, what percentage does your airport take?
or do you get the full instructor rate since you have to buy everything yourself?
My current school, we get 2/3rds of the instructor fee. I think that is reasonable and makes me feel worth my time, especially since they buy the insurance.
($21.00/hour Primary)
(22 or 23/hour advanced)
$20/hour is not bad, there are many CFIs making a lot less.
If you are busy enough getting paid $20/hour while paying your own insurance is a much better deal than getting your insurance paid for and only getting paid $15/hour.
