An overdraft occurs when a transaction exceeds the available balance in a bank account, resulting in a negative balance. Banks may cover the transaction (for a fee) or decline it. The CFPB has issued rules limiting overdraft fees on debit card and ATM transactions for large banks.
Overdrafts occur when a payment — check, debit card swipe, ACH debit, or ATM withdrawal — exceeds your available balance. Banks historically charged $25–$35 per overdraft transaction, which added up quickly on small-dollar purchases. The CFPB's overdraft rules (finalized in 2024) cap overdraft fees at $5 for large banks (over $10B in assets), though the rule faces ongoing legal challenges. Most banks offer overdraft protection: a linked savings account, line of credit, or credit card that automatically covers the shortfall. Some banks now offer 'no-fee overdraft' products that allow small negative balances (typically up to $50) without penalty. A Non-Sufficient Funds (NSF) fee is technically distinct from an overdraft fee: an NSF is charged when the bank returns the transaction unpaid (bounced check), while an overdraft fee is charged when the bank pays it (covering the negative balance). Both damage cash flow and can trigger additional fees from the payee (e.g., returned check fees from a landlord or merchant).
A linked overdraft line of credit may appear as a tradeline but is rarely a major credit factor. Unpaid overdrafts sent to collections can hurt your credit and result in account closure and a record in ChexSystems (a bank reporting bureau).
Yes. Under the CFPB's Regulation E, you can opt out of one-time debit card and ATM overdraft coverage. If opted out, overdraft transactions are declined rather than covered and charged a fee.
