What $900,000 mortgage at 6% over 30 years really costs

Your monthly repayment of A$4,317 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$3,600 is interest and only A$717 reduces the principal. This shifts gradually over 30 years.

Over the full 30-year term, you pay A$834,035 in interest โ€” 116% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
