The pros of overdraft involve providing coverage when an account unexpectedly has insufficient funds, avoiding embarrassment and "returned check" charges from merchants or creditors. But it's important to weigh the costs. Overdraft protection often comes with a significant fee and interest which, if not paid off in a timely manner, can add an additional burden to the account holder. According to the Consumer Financial Protection Bureau, customers who had overdraft protection, in fact, often paid more in fees than those without it.
