How Mortgage Repayments Are Estimated
For principal-and-interest lending, the calculator uses a standard amortising-loan formula. Each scheduled repayment includes interest for the period and an amount that reduces the outstanding principal.
For interest-only lending, the estimated repayment covers interest for the selected period without reducing the original principal balance.
Actual lender repayments may differ because lenders can apply daily-interest calculations, repayment-date conventions, rounding rules, fees and product-specific features.
What the Calculator Does Not Include
The estimate does not include:
Application or establishment fees
Annual package fees
Lender’s mortgage insurance
Offset-account balances
Redraw transactions

Fixed-rate break costs

Changes to the repayment schedule
A lender’s individual calculation method

How Extra Repayments May Affect a Loan
For principal-and-interest calculations, an additional repayment is applied to the outstanding principal each selected repayment period.
If the rate and scheduled repayment remain unchanged, reducing principal earlier may shorten the indicative repayment period and reduce estimated total interest.
Actual lender treatment can depend on the loan terms. Some fixed-rate products limit additional repayments or may charge costs.
