Most Kiwis settle for a 30-year mortgage, but you don’t need to stay locked in for that long. Mortgage optimisation can shorten your loan term and save you hundreds of thousands in interest.
Total mortgage
Average monthly repayments (30-year term, 5.5% interest rate)
In total repayments over 30 years
In interest paid over 30 years – more than the loan itself!
For this example, let’s use a mortgage of $800,000. The takeaway? Without a strategy, you risk spending decades paying interest that could have stayed in your pocket and helped fast-track your financial goals.
Every dollar you put in now saves you multiple dollars in long-term interest.
In 30 years:
$800,000 at 5.5% → $4,542/month, $835k interest
In 15 years:
Same mortgage → save about $458k in interest
In 10 years:
Same mortgage → save about $593k in interest
