Actually, if im right, theres a lot more to it, like intrests for leaving your money there... etc.  
Btw, if you go to the bank section you will see that it says this. 
Withdraw Fee: 1% of what you withdraw. 
Deposit Fee: 0% of what you deposit.  
and 
Interest Rate 2% 
Confirming what i just say.... So, just deposit your money and get lots more with time!
