Where this comes from: Repayments are calculated with a standard amortisation formula using the rate and term you enter. Real repayments depend on lender fees, offset balances and rate changes.

How this calculator works

This calculator applies the standard amortisation formula to a loan amount, interest rate and term, and shows how the balance reduces over the life of the loan.

Assumptions

  • The interest rate stays the same for the whole term
  • Repayments are made on time and in full, with no extra repayments or redraws
  • Fees, offset balances and rate changes are not included

Results are estimates for educational purposes and are not a lending decision, an approval or an offer of credit.
