Interest rate hikes are one of the biggest concerns for home loan borrowers in Australia. But what many borrowers underestimate is how even a small increase can significantly impact both monthly repayments and total loan cost.
Let’s look at a practical example.
If you have a home loan of $692,000 at an interest rate of 6.54% over a 30-year term, your monthly repayment is approximately $4,392.
Now, consider a 25 basis point (0.25%) rate hike, increasing your interest rate to 6.79%.
Here’s the real impact:
- Your monthly repayment increases by approximately $115
- Over the life of the loan, you will pay an additional ~$41,250
That’s the hidden cost of a small rate rise.
While $115 per month may not seem alarming at first, over time, it adds up to a substantial financial burden. This is why understanding interest rate movements is critical for every mortgage holder.
