How can I make withdrawals without losing interest on my Advantage Saver account?

Advantage Saver’s interest is made up of a base interest rate and bonus interest rate. You don't need to meet any eligibility criteria to receive the base interest rate.

To earn bonus interest, you’ll need to make sure your account balance at the end of the month is at least $250 higher than it was at the start of the month. The $250 can’t include interest we’ve paid to you.

Here are some examples to help explain:

Example 1:

  Account Balance CreditDebitBalanceOutcome
Opening Balance $120,000     
Deposit  $250   $120,250  
Withdrawal   $1,000 $119,250  
Closing Balance    $119,250 No Bonus Interest Paid

In this example, the balance has decreased by $750 from the opening balance. This means you aren't eligible for bonus interest as you haven’t increased your balance by $250 at the end of the month.

Example 2:

  Account Balance CreditDebitBalanceOutcome
Opening Balance $120,000     
Deposit  $250   $120,250  
Withdrawal    $120,250  
Closing Balance    $120,250 Bonus Interest Paid

In this example, the balance at the end of the month has increased by $250 from the opening balance. Congratulations, you’re eligible for bonus interest.

Example 3:

  Account Balance CreditDebitBalanceOutcome
Opening Balance $120,000     
Deposit  $250   $120,250  
Withdrawal   $1,000 $119,250  
Deposit  $1000   $120,250  
Closing Balance    $120,250 Bonus Interest Paid

In this example, you’ve withdrawn money from your account, but you‘ve deposited enough to increase the closing balance by the minimum $250 needed to earn bonus interest. Congratulations.

Is my money safe in a savings account?

Yes. Money placed in a savings account with a bank, building society or credit union is protected by the Australian Government’s Financial Claims Scheme (FCS).

The scheme protects deposits up to $250,000 per person, per financial institution. In the unlikely event that a financial institution closes you’ll have the peace-of-mind that your money is safe.

Learn more about the FCS.
