What Is Overdraft?
When a bank account balance goes below zero because a transaction exceeds the available funds.
Overdraft Explained
An overdraft occurs when you spend more money than you have in your account, causing the balance to go negative. Banks may cover the transaction and charge an overdraft fee, or they may decline it. Overdraft fees typically range from $25 to $35 per occurrence. On bank statements, overdrafts appear as negative balances and associated fee charges. When analyzing CSV data from statements, tracking overdraft fees helps identify patterns and calculate the total cost of overdrafts over time.
Technical Details
Banks handle overdrafts through several mechanisms: overdraft protection (linked savings account or credit line covers the shortage), courtesy overdraft (bank pays the transaction and charges a fee), and standard decline (transaction is rejected). The order in which banks process transactions affects overdraft occurrence; processing large transactions first can trigger multiple overdrafts on smaller subsequent transactions. Bank statements show overdraft fees as separate line items, typically described as 'Overdraft Fee,' 'OD Fee,' or 'Insufficient Funds Fee.' Running balances in CSV data clearly show when accounts enter negative territory.
Examples
- An account balance of $50 followed by a $75 purchase resulting in a -$25 balance
- A $35 overdraft fee charged after a transaction exceeds available funds
- A bank statement showing three overdraft fees totaling $105 in a single day
