Lenders quietly charge loyal customers more — typically 0.3–0.8% above what new customers get. On a $550,000 balance, half a percent is around $2,700 a year.

Australians who switched lenders saved an average of about $1,900 a year (PEXA). The calculator shows your potential number; the free TAG health check confirms it against real lender offers within 24 hours.

How much does refinancing save on average?

Around $1,900 a year for Australians who switch to a new lender, according to PEXA's refinancing research — more if your rate has drifted well above market. Your actual saving depends on your balance and rate; the calculator above gives you a personal estimate in seconds.

Does the saving outweigh the switching costs?

Usually, yes — typical refinance costs are $300–$700, so a saving of even $100 a month pays them back in months. The exceptions are large fixed-rate break costs, which is why we always get your exact break fee before recommending a switch.
