What $500,000 mortgage at 4.5% over 25 years really costs

Your monthly repayment of A$2,223 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$1,500 is interest and only A$723 reduces the principal. This shifts gradually over 25 years.

Over the full 25-year term, you pay A$266,999 in interest โ€” 67% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
