▦ How this calculator works
The calculator uses the amortising-loan formula: it converts your annual rate to a monthly rate, then solves for a fixed monthly payment that fully repays the loan (principal and interest) over the number of months in the term.
◇ Assumptions and what's not included
Lenders mortgage insurance, offset or redraw balances, rate changes over the loan term, annual fees, stamp duty and other upfront purchase costs are not included — see the Offset & Redraw and Stamp Duty calculators for those.
▤ What to do next
Compare this estimate against your lender's formal quote, test both a higher-rate and a shorter-term scenario, and confirm whether your rate is fixed or variable before committing.

Frequently asked questions
Is this a fixed or variable rate calculation?+
It works for either — enter the rate you want to test. It assumes the rate stays constant for the full term, which only holds true for a fixed-rate loan.
Does this include lenders mortgage insurance (LMI)?+
Yes. Enter a lender quote when available; otherwise the calculator uses its displayed planning estimate when LVR exceeds 80%. LMI varies by lender and borrower.
What is a comparison rate and should I use it here?+
The comparison rate includes most fees and is usually higher than the advertised rate. Using it here gives a more realistic total cost estimate.
How much extra does a longer loan term cost?+
A longer term lowers the monthly repayment but increases the total interest paid — try changing the term to see the trade-off directly.
