Further up in the thread someone said 37 million credits a week, the sort of money you can supposedly easily make with a carrier IF you stay around the bubble, however if you head in the black, it's a constant drain on your resources!
That's like buying a Ferrari for one million Euros/Pounds/Dollars etc, THEN having to pay them a couple of thousand a week for the privilege of keeping it!! :0.
I make $100m+ per week easily out in the black, I also don't have all services, many of which are unnecessary, and some I only activate when I need them, $37m a week is for everything and all running all the time, I get away with around $10-$12m per week depending on how many jumps I do with the carrier, making enough money to pay maintenance is trivial. Also you should be thanking us beta testers, the initial maintenance per week in the beta was 10x the current cost, and jump times were 2 hours+.
