A new study commissioned by the Center for Responsible Lending (CRL) examined data from 2011 to see how banks apply overdraft fees to various types of transactions. Overdrafts from debit card purchases generated a median fee of $1.75 for every dollar overdrawn. Bounced checks, meanwhile, usually earned a fee of 56 cents for every dollar over the available account balance; and ATM users paid an average 39 cents for each dollar overdrawn. For all transactions, the median overdraft fee in 2011 was $35 -- up from $34 in 2007. CRL has recommended that authorities prohibit overdraft fees on debit card and ATM transactions and ban the practice among many banks of reordering checking account withdrawals to maximize fees.
