What $300,000 mortgage at 6% over 25 years really costs

Your monthly repayment of A$1,546 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$1,200 is interest and only A$346 reduces the principal. This shifts gradually over 25 years.

Over the full 25-year term, you pay A$223,897 in interest โ€” 93% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
