Calculate weekly, fortnightly or monthly mortgage repayments
Estimate principal-and-interest or interest-only repayments for an Australian home loan. Then add regular extra repayments or a lump sum to see how the strategy may reduce total interest and shorten the mortgage term.
The result is an estimate rather than a lender quote. Actual repayments can change with the interest rate, fees, repayment frequency and loan conditions.

Mortgage repayment calculator questions
How are mortgage repayments calculated?
The estimate uses the loan balance, interest rate, loan term, repayment type and frequency you enter.
How do extra repayments affect my loan?
For principal-and-interest loans, paying down the balance sooner may reduce total interest and shorten the repayment period. Check whether your loan limits extra repayments.
Is this a lender quote?
No. It is a planning estimate and does not include every lender fee, policy or future interest-rate change.
