Key Takeaways
- The loyalty tax is the rate premium existing borrowers pay while their bank advertises sharper deals to new customers, and regulators have measured the gap for years.
- You can spot it by comparing your current rate against your lender’s new-customer offer and checking how long it has been since your last review.
- On a $600,000 loan, a gap of around 0.40% can cost more than $1,600 a year, and the figure compounds across a long loan term.
- Requesting a review, negotiating from your equity, or refinancing can close the gap, and complex borrowers often carry the widest premium.
Your bank knows exactly what it would charge a stranger walking through the door today. The question is whether that number is lower than the rate you are quietly paying on your existing home loan. The loyalty tax is the premium many long-standing borrowers pay simply for staying put, while their lender saves its sharpest pricing for new customers it has not won yet.
For most households, the mortgage is the largest monthly commitment, so even a fraction of a percentage point matters. The loyalty tax rarely announces itself. Your repayments do not suddenly jump. Instead, the discount you negotiated years ago slowly loses ground against the rates advertised to everyone else, and the drift is easy to miss until you go looking for it.
This gap is measurable and fixable. Once you know how to read your own rate against the current market, you can decide whether to negotiate, restructure, or move. As a refinancing mortgage broker, we compare your existing loan against dozens of lenders and put the real number in front of you, so the decision rests on evidence, not guesswork.
What the Loyalty Tax Really Is
The loyalty tax is not a fee on your statement or a line in your contract. It is the difference between what your lender charges you and what it offers someone applying today. How that difference forms explains why it can grow without you noticing:
The Split Between New and Existing Pricing
Lenders compete hardest for borrowers they do not yet have. To win that business, they advertise their sharpest variable rates and discounts to new applicants. Existing customers usually sit on an older discount that was set when their loan began. Over time, the two prices drift apart, because the rate offered to newcomers keeps moving while yours often stays where it was.
The Reason Your Rate Drifts Higher
In a rising-rate environment, lenders tend to pass increases on to existing borrowers in full, while softening the rates they advertise to attract new business. When rates fall, the reverse can happen, with new-customer pricing dropping faster than the rate applied to your loan. Either way, the borrower who does nothing ends up paying more than a fresh applicant for the same loan.
The Regulatory Findings Behind the Gap
The Australian Competition and Consumer Commission (ACCC) found in its 2020 inquiry that borrowers with older loans paid more than newer ones, and the gap widened the longer a loan had been held. The Reserve Bank of Australia (RBA) has reported a similar pattern, with loans around four years and older charged roughly 40 basis points more on average than newer loans. The Australian Securities and Investments Commission (ASIC) has also pointed to a pricing premium for established customers at the major banks.
How to Tell If You Are Paying the Loyalty Tax
Spotting the loyalty tax takes a short look at your own loan, not any special tools. A few checks will usually tell you whether your rate has fallen behind the market:
Checking Your Current Interest Rate
Start with the number. Log in to your banking app or grab your latest statement and find the interest rate on your loan, not the comparison rate. Note whether it is variable or fixed, because a fixed rate is locked until its term ends and will not reflect the market until then. Many borrowers cannot recall their rate, which is the inertia lenders count on. Write it down, because every other check builds on this figure.
Comparing Against New Customer Offers
Next, look at what your own lender advertises to new borrowers for the same type of loan. That is the cleanest measure of new-customer versus existing-customer pricing, because it strips out differences between banks. Compare like with like, matching your loan purpose, repayment type, and rough loan-to-value position, so you are not weighing an owner-occupier rate against an investor one. A noticeable gap is the clearest sign you may be carrying a loyalty premium. Variable rates across the market can differ by more than 2%, so it is worth comparing beyond a single lender.
Reviewing the Time Since Your Last Rate Review
The longer a loan sits untouched, the wider the gap tends to grow. Industry surveys suggest a large share of borrowers have never switched lenders, and many have not renegotiated in years. A home loan rate review roughly every 12 months keeps the drift in check. A loan you have not reviewed since before the last run of rate changes is worth a closer look.
Watching for Discount Slippage and Added Fees
The loyalty tax does not always show up as a higher headline rate. Sometimes a package discount expires, or annual fees and add-ons erode the value of a rate that still looks reasonable on paper. Read the full cost of your loan, including ongoing fees, not just the headline rate.
What the Loyalty Tax Costs Over Time
A fraction of a percentage point can feel too small to chase. On a mortgage measured in hundreds of thousands of dollars and decades of repayments, it adds up quickly:
The Annual Cost on a Typical Loan
On a $600,000 variable loan, a rate around 0.40% above the new-customer rate can add roughly $135 to $170 a month in extra interest. Across a year, that is more than $1,600 staying in the bank’s pocket rather than yours.
The Compounding Effect Across the Loan Term
Interest is charged on your outstanding balance month after month, so a small premium does not stay small. Left unchecked over several years, a modest gap can cost tens of thousands of dollars in additional interest across the life of a loan. Reducing your rate early in the term generally saves more than the same reduction made later, because more of your balance is still outstanding.
The Impact of a Larger Loan Balance
The bigger your remaining balance, the more each basis point matters. Industry analysis suggests that a borrower who took out a loan several years ago and never renegotiated could be paying well above the sharpest rates available today, with potential savings running into five figures over a couple of years once switching costs are counted. Your own number depends on your balance, rate, and remaining term.
These figures are general estimates only. Your actual position depends on your loan size, interest rate, remaining term, and your lender’s fees, so treat them as a starting point, not a quote.
How to Close the Gap With Your Lender
Finding the gap is the hard part. Closing it is usually more straightforward, and you have more than one option:
Requesting a Rate Review First
Ask your current lender to match or beat what it offers new customers. A short call to the retention team, armed with the new-customer rate and a competing offer, often produces a discretionary discount. Lenders would generally rather trim your rate than lose your loan to another bank.
Negotiating From Your Equity and Credit Position
Your bargaining power grows with your position. Borrowers with at least 20% equity and a solid repayment history usually have more room to negotiate, because they represent lower risk to the lender. Raising the prospect of switching can help, since the risk of losing your business often prompts a better offer.
Refinancing to a More Competitive Loan
When your lender will not move far enough, refinancing to another lender resets your rate to current market pricing and can unlock features your old loan lacked. The process of changing lenders typically runs four to six weeks from application to settlement, and a broker manages the paperwork and lender correspondence on your behalf.
Weighing the Costs of Switching
Refinancing is not free, so the saving has to outweigh the cost of moving. Typical costs include a discharge fee from your current lender, possible application and valuation fees, and break costs if you are leaving a fixed rate early. Some lenders offer cashback deals of $2,000 to $4,000 that can offset these, though a cashback paired with a higher rate can cost more over time. Where the numbers do not stack up, other options if you cannot refinance can still trim your rate without switching.
Why Complex Borrowers Carry a Bigger Loyalty Tax
The loyalty tax is not spread evenly. Borrowers with more involved finances often pay the widest premium, usually because reviewing their loan feels harder and fewer lenders court them. The very features that make a file complex also make a rate review more valuable:
Self-Employed and Variable Income Borrowers
Self-employed borrowers, contractors, and those with variable income are sometimes parked on higher rates, because refinancing seems to demand more paperwork. In practice, the right lender treats two years of tax returns and business financials as routine. A review is often well worth the effort, given how far a long-held loan can drift.
Trust and Company Structures
Loans held through trusts or company structures can be harder to compare, which is why the loyalty tax tends to settle in. Not every lender prices these arrangements the same way, so a borrower who set up the structure years ago may be sitting well above what a specialist lender would offer today.
Self-Managed Super Fund (SMSF) Loans and Property Portfolios
SMSF loans and portfolios spanning several properties multiply the effect. A small premium on one loan is one thing; the same premium repeated across a portfolio compounds quickly. From 10 August 2026, an SMSF can no longer borrow to buy residential property, though existing loans are protected and can still be refinanced, so reviewing the rate on an SMSF loan still matters. Outside super, investors reviewing equity across multiple properties can also find opportunities beyond a lower rate, such as turning equity into a portfolio.
How Ongoing Reviews Keep the Loyalty Tax Away
Escaping the loyalty tax once helps, but the gap reopens the moment a loan is left to drift again. A steady review habit turns a one-off saving into a lasting one:
Scheduling Regular Rate Reviews
A rate that was competitive at settlement will not stay that way forever. Setting a fixed point to review your loan, rather than waiting to feel stung, keeps you ahead of the drift. We review our clients’ rates every six months after settlement, so a widening gap is caught early, not years later.
Tracking Market Movements and Lender Changes
Lenders adjust their pricing constantly, and not only when the RBA moves. The cash rate sat at 4.35% through the middle of 2026 after a run of increases, yet new-customer offers kept shifting underneath that headline. Lenders also move variable rates independently of the cash rate, on their own funding costs and competition for new business. Keeping an eye on the market tells you whether your rate is still holding up.
Acting Before the Gap Widens
A review that flags a premium is the prompt to act while the saving is largest. Leaving it for another year lets the gap keep working against you, so a small delay can cost more than acting would.
Where This Leaves You and Your Home Loan
You no longer have to wonder whether your bank is quietly charging you more than the person applying today. The moment you check your rate against the market, the advantage that inertia handed your lender starts working for you instead.
The next move is straightforward. Pull up your current rate, compare it against what your lender advertises to new borrowers, and decide whether the gap is worth closing. Whether you negotiate, restructure, or move, acting sooner keeps more interest in your hands.
When you want that number checked across the market, Unconditional Finance can compare your loan with a wide panel of lenders and keep reviewing it so the gap does not reopen.
Frequently Asked Questions (FAQs)
1. Is the loyalty tax legal in Australia?
Yes. Charging existing customers a different rate to new ones is legal, and no rule forces a lender to automatically pass its sharpest pricing on to you. Regulators including the ACCC and the RBA have raised concerns about transparency, but the responsibility to check your rate still sits with you.
2. How much more do existing customers usually pay?
It varies by lender and by how long you have held the loan. Regulator findings point to a premium of about 0.30% to 0.50% for established customers at the major banks, and the dollar cost grows with the size of your loan.
3. How often should I review my home loan?
Around once every 12 months suits most borrowers, and sooner if rates have moved or your circumstances have changed. We run a rate review for our clients every six months after settlement to keep the drift in check.
4. Will my bank lower my rate if I ask?
Often, yes, though it is at the lender’s discretion. Coming prepared with your lender’s new-customer rate and a competing offer strengthens your case. When the retention team will not move far enough, refinancing becomes the alternative worth weighing.
5. Does refinancing hurt my credit score?
A single credit enquiry from a new lender may cause a small, temporary dip. Multiple enquiries in a short window can have more effect, so compare options before applying, not lodging several at once. Over time, a loan structure that keeps your repayments manageable can support a healthier credit profile.
6. Can self-employed borrowers escape the loyalty tax?
Yes. Self-employed and variable-income borrowers can review and refinance like anyone else, usually by providing two years of tax returns and business financials. Because these files are sometimes left on older rates for longer, the potential saving from a review can be larger, not smaller.
