A debit excess interest charge occurs when your transaction account balance falls below zero without prior arrangement. This typically happens if you make a payment or withdrawal that exceeds the available funds in your account, effectively creating an unplanned overdraft.
When your account remains overdrawn, the bank applies interest on the negative balance until the account is brought back into credit. This is distinct from a standard arranged overdraft facility, which is a pre-approved credit limit specifically designed to cover such shortfalls.

Steps to address an overdrawn account
If you notice your account is overdrawn, you should address it as soon as possible to stop further interest from accruing. Here is the standard way to resolve a negative balance:
- Check your balance: Log in to the CommBank app or NetBank to confirm the current negative amount. Ensure you check both your "Available balance" and "Account balance" to see if any recent transactions are still processing.
- Transfer funds: Move money from another personal account or have someone transfer funds into your account immediately. This brings the balance back to zero or above.
- Review transactions: Identify why the account went overdrawn. Look for recurring direct debits or automated payments that might have cleared unexpectedly.
- Contact the bank: If you are unable to clear the negative balance, contact Commonwealth Bank support to discuss the situation. They can explain the specific fees applied and potential options for your account type.
Troubleshooting common issues
Login or MFA difficulties
If you cannot access your account to check the balance, it is often due to an expired session or a multi-factor authentication (MFA) delay. Try closing the app entirely and restarting your device. If the issue persists, call the CommBank support line for manual account verification.
App or browser errors
Sometimes the interface may show a delayed balance, particularly during weekend hours. Clear your browser cache or check if there is an update available for the CommBank app in the app store. If the figures do not update after a few hours, contact the bank to confirm your actual balance.
Account access or lockouts
If your account is locked due to security protocols following an overdrawn status, you will need to verify your identity to regain access. This is a security measure. You will generally need to visit a branch with your identification or speak to a representative via the phone banking service to resolve the block.
Pro-Tip: Set up low-balance alerts in the CommBank app. By receiving a notification when your account hits a specific threshold, you have a better chance of transferring funds before an unplanned debit excess situation occurs.
Frequently Asked Questions
Why was I charged interest even though I don't have a loan?
Interest is charged because the account has effectively borrowed money from the bank by going into a negative balance. For example, if you have $10 in your account and a $50 bill is processed, you are $40 overdrawn. The bank charges interest on that $40 until you deposit enough money to cover it. The main limitation is that interest accrues daily, so leaving the account overdrawn for a long time increases the total charge. You should deposit funds as soon as you notice the negative balance.
Can I have these fees waived if it was an accident?
In some cases, if you have a strong history of maintaining a positive balance, you might be able to request a reversal of a fee. This typically involves speaking to a representative to explain that the overdraft was an isolated incident, such as a timing mismatch between a deposit and a direct debit. Note that this is not a policy and depends on your account standing. Your best next step is to call customer service and politely explain your situation.
