The important thing to remember is that when you deposit money into your account, you are loaning the bank money. Open an account that charges little or no service fees. Be aware of all the possible fees that the bank can charge you. This way, you won't get any surprises at the end of the month. Many accounts provide you with a debit card, but their convenience makes spending all too easy.
Transaction fees can also add up quickly.
Determine how much money you'll need for a given period, and then withdraw that amount at one time, rather than making frequent withdrawals. Ultimately, you'll save on transaction fees. Keep debit cards for emergencies or preplanned purchases. If you have multiple bank accounts open and never use them, or just keep small balances lingering inside each one, consider closing them and keeping only one account. Even if you drive a Ferrari and live in an immaculate condo, you may still be bankrupt.
