What $300,000 mortgage at 6.5% over 25 years really costs

Your monthly repayment of A$1,620 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$1,300 is interest and only A$320 reduces the principal. This shifts gradually over 25 years.

Over the full 25-year term, you pay A$246,149 in interest โ€” 103% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
