What $400,000 mortgage at 5.5% over 30 years really costs

Your monthly repayment of A$1,817 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$1,467 is interest and only A$350 reduces the principal. This shifts gradually over 30 years.

Over the full 30-year term, you pay A$334,093 in interest โ€” 104% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
