Introductory rate calculator

How to use the introductory rate calculator

1. Enter your loan amount

   Type the amount you plan to borrow, starting from the $250,000 default.

2. Choose your loan term

   Select the full mortgage term in years (30 years by default).

3. Pick repayment frequency

   Select monthly, fortnightly or weekly repayments from the dropdown.

4. Set introductory term and rate

   Choose how long the honeymoon discount lasts (default 5 years) and enter the introductory interest rate (default 4.00%).

5. Enter revert variable rate

   Input the ongoing variable interest rate (default 5.50%) that applies once the introductory period ends.

To see how upfront and ongoing fees change the true cost of a discounted rate, run our comparison rate calculator.

You see your repayment during the introductory term, your higher repayment after reverting to the variable rate, total interest on the honeymoon loan, and total interest if the loan stayed at the variable rate from day one.

What the honeymoon rate comparison covers

Why the revert rate matters for visa holders and expats

A honeymoon rate only saves money if the revert variable rate stays competitive, or if you can refinance when the discount ends. If you're on a bridging visa or temporary visa, your ability to switch lenders later depends on your visa status, partner situation and equity at that time.

Lenders also apply APRA's 3.0 percentage point serviceability buffer to the ongoing rate rather than the temporary discount. If you're already paying a high revert rate from overseas, some lenders on our panel assess an eligible Australian expat refinance with a 0% servicing buffer up to 80% LVR, with no cash out.
