The Center for Responsible Lending recently issued this 13 page report (PDF) titled, "Overdraft Explosion" . Bankdraft fees for overdraft protection has increased over 35 % in the past 2 years. At an average fee of $34 per overdraft, and over 50 million Americans overdrawing their checking accounts at least once over a 12-month period, that adds up to over $24 billion in fees for the baking industry.
No wonder banks push this "service" to customers even though a survey says most would prefer a denial of service rather than overdraft protection.
Numbers and charts are included in this report.
