Repayment estimate

Home loan repayments

Explore a principal-and-interest repayment using your loan amount, rate, term and preferred repayment frequency. Check the example loan amount and term, then enter the interest rate you want to explore.

Your scenario

Enter your figures to see an estimate.

Enter an annual interest rate, check your loan amount and term, then select Calculate repayment estimate.

The calculator uses the rates you enter. It does not display a lender rate or product offer.

General estimate only. This is not credit assistance, a quote, offer, recommendation or approval. It uses the nominal annual rate divided by the selected number of repayment periods and assumes a constant rate and regular principal-and-interest repayments. It does not reproduce lender-specific daily accrual or rounding and excludes fees, offsets, redraw and rate changes. Talk with a broker about your actual options.
