The loyalty tax: why long-term customers often pay more — and how to fight it
Walk into almost any lender as a new customer and you will be offered a sharper rate than many of that lender's existing borrowers are paying for the identical loan. This gap has a name — the loyalty tax — and it is one of the most reliable features of the Australian home loan market. Regulators have examined it, lenders quietly rely on it, and borrowers pay it mostly because they never check. The fix does not always require refinancing: often a single structured phone call, called a repricing request, closes most of the gap. Here is why the gap exists and exactly how to run that call.
Why existing customers pay more
No lender publishes a policy of charging loyal customers extra, but the pricing mechanics produce that result naturally:
- Front-book vs back-book pricing. Lenders compete for new business (the front book) with discounts and offers, while existing loans (the back book) drift with standard variable movements. Over years, the two diverge.
- Discounts that never update. The discount you negotiated at settlement was calibrated to the market at that time. The market moved; your discount did not.
- Inertia does the work. Refinancing takes effort, so most borrowers do not act, and pricing teams know it. The expected cost of losing a slice of inattentive customers is lower than the cost of repricing the whole back book.
None of this requires bad faith — it is competition working hard at the point of acquisition and barely at all afterwards. The practical consequence: the longer since you last negotiated, the more likely you are paying above the going rate for your own loan.
Step 1: Find out what you're actually paying
You cannot fight a gap you have not measured. From your statement or banking app, note your current interest rate, loan type (owner-occupier or investment, principal-and-interest or interest-only), remaining balance and any package fees. Then estimate your LVR — balance divided by a realistic current property value; our [LVR and LMI calculator](/calculators/lvr-lmi) makes this quick. LVR matters because lenders price in bands, and if your equity has grown you may qualify for a cheaper band than the one you were priced in originally.
Step 2: Gather your evidence
A repricing request succeeds on specifics, not sentiment. The evidence that moves a pricing team:
- Your own lender's new-customer rate for the same loan type and LVR, from their website. This is the strongest card: it removes any argument about different products or credit profiles.
- Two or three written competitor offers or advertised rates for a comparable loan at your LVR. Advertised rates are useful; a genuine approval-in-principle or a broker's comparison is stronger.
- Your standing as a customer: clean repayment history, time with the lender, other products you hold, and your LVR band.
Skip appeals to loyalty — pricing teams respond to the credible risk of losing the loan, not to tenure by itself. The evidence exists precisely to make that risk credible.
Step 3: Run the repricing request
Call your lender and ask for the home loan retention or pricing team — front-line staff often cannot approve discounts, so being routed correctly matters. Then keep the script simple:
- State your rate and what the lender offers new customers for the same loan and LVR
- Mention the competitor rates you have gathered
- Say plainly that you are reviewing the loan and prepared to refinance if the gap cannot be closed
- Ask: "What is the best rate you can offer to keep this loan?"
Some lenders respond on the call; others lodge a pricing request that takes a few days. If the first answer is weak, ask for it to be escalated as a formal pricing review — and if you hold your loan through a broker, ask the broker to lodge the repricing request instead; they run these regularly, know each lender's process, and can lodge it with the evidence already attached.
Get any offer in writing, and check whether it is a genuine rate reduction or a temporary discount that expires.
A 15-minute chat is usually enough to map your options — free, no obligation.
Step 4: Decide with the numbers, not the relief
A quick concession from your lender feels like a win, but measure it before accepting. Model your balance over your remaining term at the new offer versus the best external offer using our [repayment calculator](/calculators/repayment). If your lender closes most of the gap, staying often wins once you count the switching costs — discharge fee, government registration fees, time. If a meaningful gap remains, refinancing is the honest answer; our [step-by-step refinance guide](/articles/refinance/how-to-refinance) covers the process, and the [refinance page](/loans/refinance) covers what lenders assess. Beware settling for a token discount simply because the call was easier than the paperwork — that is the inertia the loyalty tax feeds on.
Make it a habit, not a one-off
The loyalty tax is not cured by one phone call; it regrows. A rate you negotiated two years ago is subject to exactly the same drift as the rate you started with. Put an annual reminder in your calendar to spend twenty minutes checking your rate against your lender's new-customer pricing, and treat fixed-rate expiries as mandatory review points — our [fixed rate cliff guide](/articles/refinance/fixed-rate-cliff-guide) explains why loans roll onto expensive revert rates when nobody is watching. Borrowers who review annually rarely accumulate a large gap; borrowers who never review almost always do.
When repricing won't be enough
Repricing has limits. It cannot fix a loan whose structure no longer suits you — wrong features, wrong split, no offset — and it will not help much if your lender's sharpest pricing is simply uncompetitive for your profile. It also does nothing for borrowers who want to change loan term, release equity or consolidate debt, all of which need a new application. In those cases, go straight to comparing the market rather than negotiating a better version of the wrong loan.
Talk it through with a broker
A broker can tell you quickly whether your rate is above the market for your LVR and loan type, lodge the repricing request with your current lender on your behalf, and line up the refinance alternative if the lender does not move. If you have not checked your rate in over a year, [get in touch](/contact) — the first look costs nothing and the loyalty tax only compounds while it goes unmeasured.
Frequently asked questions
What is the loyalty tax on home loans?
It is the gap between the rates lenders offer new customers and the rates many existing customers pay for the same loan. It arises because lenders discount heavily to win new business while existing loans drift upward with standard rate movements, and most borrowers never renegotiate.
What is a repricing request?
A repricing (or rate review) request is a formal ask to your current lender to reduce the rate on your existing loan, usually handled by their retention or pricing team. It requires no new application, no valuation in most cases, and no change of loan — just evidence that your rate is above what the market, including your own lender, offers comparable new borrowers.
Will asking for a lower rate affect my credit score?
No. A repricing request with your existing lender is not a credit application, so no enquiry is recorded on your credit file. A refinance to another lender, by contrast, is a full application and does involve a credit check.
How often can I ask my lender for a better rate?
There is no formal limit — an annual request is reasonable, and any trigger event such as a fixed term expiring, your LVR dropping below 80 per cent, or a visible gap opening against new-customer rates justifies asking sooner. Lenders decline requests they consider unwarranted, but asking costs nothing.
What evidence works best in a repricing request?
The strongest evidence is your own lender's advertised new-customer rate for the same loan type and LVR, because it eliminates excuses about product differences. Add two or three competitor rates for comparable loans, your clean repayment history, and your current LVR band. A broker can package this evidence and lodge the request for you.
Is it better to reprice or refinance?
Reprice first — it is free, fast and carries no credit enquiry. If your lender closes most of the gap, staying usually wins after switching costs. If a meaningful gap remains, or your loan's structure no longer fits, refinance. The mistake is accepting a token discount because the phone call was easier than the paperwork.
