How this estimate works

Illustration only, not financial advice, a loan offer or lender approval. Monthly principal-and-interest repayments, a constant nominal annual rate divided by 12, and no offset, redraw, interest-only periods or rate changes. Figures are rounded to whole dollars; lenders may calculate differently.

The one-off payment is applied after the selected number of monthly repayments, before the next month’s interest. Regular repayments stay unchanged. If the balance is smaller, only that balance is paid. Assumes extra payments are permitted without fees.
