What $500,000 mortgage at 5% over 20 years really costs

Your monthly repayment of A$2,640 covers both interest and principal. In the early years, the majority goes toward interest โ€” in month 1, approximately A$1,667 is interest and only A$973 reduces the principal. This shifts gradually over 20 years.

Over the full 20-year term, you pay A$233,558 in interest โ€” 58% of the loan amount. This is why extra repayments are so powerful: use the slider above to model the impact.
