Whats the least amount of money you can have in your account, and not have thee bank take money out of it for interest?
My bank doesn't do this. It's going to be different for different banks. You need to read your paperwork, or call and ask a teller at your bank.
Depends on what bank you use. Mine is $25.
Banks usually pay interest not take it away. However, my bank charges a fee of balance falls below $5. You will need to ask your bank because they are all different.
im allowed to be -500,for a week with no charges,all banks are differant
