Potential saving

$307/month

Switching from your 6.50% rate to Pacific Mortgage Group’s 5.59% — the lowest owner-occupier rate in our comparison — could cut your repayments by about $307 a month ($3,678 a year), and save roughly $91,960 in interest over your remaining 25 years.

How this works

We compare your current rate against the owner-occupier principal-and-interest rates in our live home-loan comparison, then estimate the repayment and interest difference over your remaining term using a standard amortisation model. The figures are general estimates — your real saving depends on the comparison rate (which folds in fees), your loan-to-value ratio, your repayment type, and any offset or redraw you use. Treat this as a starting point, not advice, and confirm the numbers with each lender.

Frequently Asked Questions

How much can I save by refinancing my home loan?

It depends on the gap between your current rate and the best rate you can move to, your loan balance, and how long you have left. Even a fraction of a percent off a large balance can save thousands a year in repayments and tens of thousands in interest over the life of the loan. This tool estimates the difference using the lowest owner-occupier rate in our live comparison.

Is it worth refinancing for a small rate difference?

Often, yes — but weigh the savings against switching costs. Discharge fees, settlement and any new lender fees can run to several hundred dollars, and some loans charge an annual package fee. If the interest saved over a year or two clearly beats those costs (and you'll keep the loan that long), refinancing usually pays off. A cashback offer can cover the switching costs entirely.

What is a refinance cashback?

Some lenders pay a one-off cash incentive when you refinance an existing home loan to them, usually scaled to your loan size and paid within a couple of months of settlement. They typically require a loan-to-value ratio of 80% or less and exclude refinances within the same banking group. Always check the rate as well — a sharp cashback on a mediocre rate can cost more over time than a lower rate with no cashback.

Does refinancing hurt my credit score?

A refinance application creates a credit enquiry, which can dip your score slightly and temporarily. Making many applications in a short window has a larger effect, so it's better to compare first and apply once. The long-term saving from a lower rate generally outweighs a small, short-lived change to your score.

Is this refinance calculator financial advice?

No. It gives general estimates using a simplified model (constant interest rate, principal-and-interest repayments, no fees or offset) and the advertised rates in our comparison. Your lender's figures, your LVR and your specific circumstances will differ. Confirm details with each lender and consider your own situation before deciding.
