The good news? Making extra repayments can significantly reduce your loan balance, cut years off your mortgage, and save you a substantial amount of money in interest.

Let’s say you take out a $400,000 mortgage at 5% interest for 30 years.
- Without extra repayments:
- Monthly repayment = $2,147
- Total interest paid = about $373,000
- With an extra $200/month:
- Loan term reduced by 5 years and 4 months
- Total interest saved = about $70,000
