Loaded insurance rates you are seeing for O/O hauling crude

I'm trying to figure out, what kind of insurance rates are you paying to the company you are leased onto?

I am not talking about your bobtail insurance cost, I am specifically looking for the amount you are billed each week or month by the carrier you are leased onto while under a load.

Example: At the company I was leased onto last year, they retained $58 per week to cover the insurance they had on my power until while I was under their load.

 

Thanks for the feedback! I'm trying to understand if it makes sense for me to go and form my own authority if I am already picking up 100% of the cost of the insurance.
