The Loyalty Tax: What Staying Put Really Costs

Summary:

If you have stayed with the same lender for years, this guide shows what that loyalty could be costing you. It also helps you decide whether refinancing your home loan is worth it right now.

• The loyalty tax is the gap between your bank’s new-customer rate and the higher one you are left on. It is worth about 0.56 percentage points, or roughly $3,360 a year on a $600,000 loan.
• No cut is expected before 2027, and the Reserve Bank has warned it could raise again. Waiting is a gamble both ways, and the sharpest new-customer deals come and go fast.
• Switching pays off when your monthly saving beats the cost of moving. Even a 0.2 per cent gap was about $100 a month on one $750,000 review.
• Asking your bank to reprice is a smart first step. The sharp rate often only lands once you request a discharge authority, and a retained rate can drift back up.
• Fixing protects against a rise, but you miss any fall and can pay a break fee. Splitting the loan gives you some of both.
• A softer valuation lifts your LVR, but a conservative figure can be challenged. On one deal, five missed comparable sales added about $25,000 and cleared LMI.

If you have been with the same lender for a few years, it is easy to assume your rate is as good as it gets. Your loan settled before the rate rises. You have never missed a repayment. Loyalty should count for something. Yet the sharpest pricing usually goes to new customers, not to you.

That gap has a name: the loyalty tax. On a $600,000 balance it can add up to around $3,360 a year in extra interest, going by the back-book pricing regulators have flagged. This guide shows what it costs, when to refinance your home loan, and how to decide.

What is the loyalty tax, and why does your bank let you pay it?

The loyalty tax is the gap between the rate your lender offers new customers and the higher rate it charges you. Banks compete hard for new business. They count on existing customers not checking. The Australian Competition and Consumer Commission (ACCC) and the Australian Securities and Investments Commission (ASIC) have both found that existing borrowers pay more than new ones.

There is a reason the sharpest rate rarely lands in your inbox. When you ask for a better deal, a lender first weighs how long you have held the loan, your equity, your savings and expenses, and your credit profile. It does this even on a spotless record.

New-customer pricing is called the front book. Existing-customer pricing is the back book. The two are set separately. Big-bank existing customers pay in the order of 0.30 to 0.50 per cent more than new customers, on ACCC and ASIC findings (accc.gov.au). The current back-book gap has been measured at around 0.56 percentage points, which is why staying put can drain real money over a year.

Has the rate picture shifted, and are the sharpest deals being pulled?

As of August 2026, the Reserve Bank of Australia (RBA) cash rate is 4.35 per cent. It has held since mid-June, according to the Reserve Bank of Australia (rba.gov.au). No cut is expected before 2027. The RBA has also warned it could raise again if inflation proves stubborn. So waiting for relief is a gamble in both directions. The sharpest new-customer deals can come and go quickly too.

Two things follow. Even while the cash rate sits still, lenders keep competing for new borrowers. A sharp deal can be on the table now and gone next month.

Waiting until money is tight is the worst time to move. In our experience, borrowers who leave a review until they are stressed can pay materially more, sometimes one to three percentage points. They can also lose access to the leanest lenders. Acting from a position of stability keeps your options open. If the gap is real for you, refinancing your home loan is one way to close it.

How much lower does a new rate need to be to make switching worth it?

There is no single magic number. Switching is worth it when the monthly interest you save beats the cost of moving. Work it out simply. Take your switching costs and divide by your monthly saving. That gives you a break-even in months. The MoneySmart mortgage switching calculator (moneysmart.gov.au) does the maths for you.

Even a small gap adds up. In one real Fox review, about 0.2 per cent on a roughly $750,000 loan came to around $100 a month. That is a real customer example, not a quote or an offer.

The rate is only part of the decision. What often matters more is structure. An offset account. Redraw. Whether variable, fixed or a split suits how you manage money. A review looks at all of it, and it costs you nothing. The real decision is the structure that fits your life, not timing the RBA.

Should you ask your bank to reprice first, and will it match the new-customer rate?

Yes. Asking your lender to reprice is a sensible first step, and MoneySmart suggests doing exactly that before you switch. Be ready to move, though. The sharpest rate often only appears once you request a discharge authority. That is the form that starts moving your loan to another lender. So that repricing offer is a reaction to losing you, not a reward for loyalty.

There is a pattern worth knowing. Once you lodge the discharge request, some lenders slow the paperwork. Then a retention team calls with a better rate. On a variable loan, that retained rate can drift back up over time. The win can fade if you are not watching. So we compare your offer against the wider market before you accept it. Then you know whether staying really is your best move.

Fix now or stay variable, and what if you fix and rates fall in 2027?

Fixing trades flexibility for certainty. A fixed rate locks your repayment, so a future rise cannot touch you during the fixed term. The trade-off is real. If rates fall, you do not share in the drop. Breaking a fixed loan early can also trigger a break fee. Staying variable keeps you flexible and open to any cut. The risk is that a rise flows straight through.

Here is a real example. One customer we reviewed refixed to a noticeably lower rate and saved about $350 a month. Within a few months, that saving had already outrun the break cost of leaving their old fixed loan. That will not be everyone’s outcome, but it shows why the break fee is a number to weigh, not a reason to freeze.

Prefer the security of fixing, but worry about missing a future cut? You can split the loan. Fix only part of it and keep the rest variable. You can also add a rate-lock fee to hold a fixed rate between approval and settlement, if you fear it will move first.

Two things are worth keeping in mind. A cut is not always passed on in full. Many fixed loans also cap extra repayments, often around $10,000 a year. With no cut expected before 2027, fixing today is less about catching a fall and more about guarding against a rise. This is the fixed vs variable home loan decision, and our guide to a fixed, variable or split structure walks you through it.

Is a review still worth it if your equity dropped when prices fell?

Often, yes. Your equity depends on your property’s current value, and a valuation is not one fixed number. As of mid-2026, CoreLogic reported national dwelling values down 0.4 per cent for the month. Sydney and Melbourne were softer over the June quarter, while Brisbane, Perth and Adelaide kept rising, but more slowly. A lower valuation lifts your loan-to-value ratio (LVR). Even so, a conservative figure can often be challenged.

In one deal we saw a 10 to 20 per cent difference between valuation methods. That was worth about $100,000 on a single property. A short-form or desktop valuation can be challenged. You do it with three or more genuine comparable sales from the past six months.

On one refinance, five missed comparable sales added about $25,000 to the valuation. That pushed the loan under the threshold. It cleared lenders mortgage insurance (LMI), saved around $15,000, and the customer moved to a lower rate. If your equity is under 20 per cent, LMI may apply, and MoneySmart notes you can ask your current lender about an LMI refund.

Is refinancing worth it for your situation?

Refinancing is not right for everyone, and a good broker will tell you when to stay put. It tends to be worth a proper look if any of these fit you. You have not reviewed your rate in two years or more. Your fixed term is ending. You want to consolidate debt or access equity. Your repayments are stretching your budget. In those cases you may be eligible for a sharper deal, and a review confirms it either way.

Already struggling to meet your repayments? A new loan is not the first answer. Speak with a free financial counsellor through the National Debt Helpline (ndh.org.au, 1800 007 007) first. For most people, though, a mortgage refinance review simply confirms whether you are on a fair deal. It costs nothing to find out.
