Things to know about this calculator:

When comparing options, the calculator identifies the option where you'll pay the least in total interest (compared against the option where you'd pay the most in total interest).

Where you’ve split your home loan into two or more portions, total repayment means the combined repayments for all portions of the loan. Once a portion of the loan has been repaid, your total repayment amount will reduce accordingly.

Interest rates are based on having a minimum of 20% equity.

To calculate results and compare options, it assumes:

  • *The interest rate selected remains the same for the relevant loan term. Realistically, the interest rate is likely to change over the relevant loan term
  • You make all your repayments in full and on time
  • You pay the minimum required, and don't make any additional lump sum payments or borrow more under the loan
  • Your repayment amounts are calculated on a 'principal + interest basis' for the loan term and therefore doesn't work for revolving loans.

Generally you’ll need 20% equity. In limited circumstances we may lend to borrowers with a minimum of 10% equity but this is subject to loan-to-value ratio (LVR) restrictions.
