Interest Only repayment changes

From 23 May 2016, we’re changing the way your interest only monthly repayments are charged to align to industry standard. The new interest repayment methodology  will calculate interest daily on the outstanding balance for that day and charge it monthly, based on the number of days in that particular month. Repayments will continue to be monthly and the total annual interest paid remains the same.

Detail on these changes has been sent to you by post, but more information about these changes is available below, including examples and frequently asked questions.

An example of how the monthly repayment calculation (excluding any fees & charges) could work is:

Example Loan amount Interest rate Monthly Interest Charged calculation Monthly Interest charged $ amount Annual Interest Charged
Current monthly repayment calculation
Until 22 May 2016
$100,000 5% p.a. Annual interest divided by 12 Feb (29 days) = $416.67

Mar (31 days) = $416.67

New monthly repayment calculation
From 23 May 2016 
$100,000 5% p.a. Annual interest divided by 365 multiplied by the number of days in the month Feb (29 days) = $397.26

Mar (31 days) = $424.66
