Frequently asked questions

How does bonus interest work?

Increase the balance of your Advantage Saver account by $250 before the end of each month (excluding interest payments, withholding tax and fees) to earn bonus interest.

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:

Opening balance Deposits Withdrawals Closing balance
$50,000 + $250 - $1,000 $49,250

No bonus interest paid
$50,000 + $250   $50,250

Bonus interest paid
$50,000 + $1,250 - $1,000 $50,250
