You ring your bank and ask for a better rate on your home loan. “Sorry, that’s the best we can do.” So you start looking around, get pre-approval somewhere else, and go back to hand in your notice — and suddenly there’s a whole new rate on the table. The one they swore didn’t exist.
If that’s happened to you, you’re not imagining it, and you’re not being difficult. It’s how the system is built. There’s even a name for the money it quietly costs you: the loyalty tax.
What the loyalty tax actually is
The loyalty tax is the gap between the sharp rate your bank offers new customers to win them over, and the older, higher rate it leaves you sitting on once you’re already in the door.
Banks know that switching a home loan feels like a hassle. Paperwork, valuations, a fortnight of admin — most people never get around to it. So the safest customer for a bank is a loyal one who never asks any questions. New customers get the attention-grabbing rate. Existing customers get whatever they’re willing to keep paying.
This isn’t a conspiracy theory or one dodgy lender. Australia’s competition watchdog, the ACCC, ran a full inquiry into exactly this.
The numbers back it up
In its Home Loan Price Inquiry, the ACCC found that borrowers who’d had their loan for a while were paying noticeably more than people taking out a brand-new loan:
- Loans that were three to five years old carried rates around 0.58% higher than the average new loan.
- Loans that were ten years or older were paying about 1.04% more — more than a full percentage point.
That doesn’t sound like much until you turn it into dollars. The ACCC’s own example: a borrower with a loan three to five years old could save over $1,400 in the first year by switching to a sharper rate — and more than $17,000 over the remaining life of the loan.
That’s real money. It’s the family holiday, a chunk off your next car, or years shaved off your mortgage — sitting there, unclaimed, because nobody picked up the phone.
(The ACCC figures are from its 2020 inquiry. The gap moves around with the market, but the pattern — loyal customers paying more — has held for years.)
Why the good rate only appears when you’re walking out the door
Here’s the part that stings. Your bank almost always could give you a better rate. The “computer says no” answer is a first line of defence, not the final word.
Retention teams — the people whose actual job is to stop you leaving — usually have a stronger rate ready to go. But it only comes out once you’ve done the hard yards: got pre-approval elsewhere, or lodged a discharge form to move your loan. In other words, you have to credibly prove you’re leaving before they’ll fight to keep you.
Cashback offers tell the same story. When a lender waves a few thousand dollars at a new customer to switch across, they’re showing you there’s flexibility in the system. It’s just pointed at winning new business, not rewarding the customers they already have.
You don’t always have to switch to win
This is the bit most articles skip, and it’s the one that saves you the most hassle.
You do not have to actually move banks to get the better rate. Very often, the smarter play is to get your existing lender to reprice your loan — same bank, same account number, lower rate — so you keep the good rate without the paperwork, the new applications, or the discharge process.
The trick is knowing what a genuinely competitive rate looks like right now, and asking the right way. When your bank can see you know the market — and that you’re ready to move if they don’t budge — the “best we can do” tends to improve very quickly.
That’s exactly the leverage a broker brings to the table, without you having to spend your evenings on hold.
How a broker changes the maths
A mortgage broker doesn’t work for the bank. We work for you, across a whole panel of lenders, so we’re not talking you into one bank’s product — we’re comparing them and finding the one that fits.
Here’s how we usually play the loyalty tax:
- We check where you actually stand. What rate are you on, and how far off the pace is it compared to what’s live in the market today?
- We go to your current lender first. In a lot of cases we can get them to reprice — you keep your loan, drop the rate, and skip the switching hassle entirely.
- If they won’t move, we do the switching for you. We handle the comparison, the application and the paperwork, and only recommend a move if you’re genuinely better off after any fees.
Either way, you’re no longer the customer who quietly pays more for staying put.
A quick self-check: are you paying the loyalty tax?
Ask yourself:
- Have you had your home loan for more than two years without reviewing the rate?
- Do you actually know your current interest rate off the top of your head? (Most people don’t — and that’s exactly what the loyalty tax relies on.)
- Have you seen new-customer or cashback offers advertised that look sharper than your rate?
- Is a fixed-rate period coming to an end in the next six months?
If you answered yes to any of these, there’s a decent chance you’re paying more than you need to — and it’s worth a five-minute conversation to find out.
Frequently asked questions
How do I ask my bank for a better rate?
Call the retention or “customer loyalty” team, not the general line, and tell them you’re reviewing your options. It helps enormously to quote a specific competitive rate you’ve seen. If you’d rather not do the negotiating yourself, a broker can do it for you and knows what number to push for.
Will refinancing hurt my credit score?
Applying for a new loan does leave a mark on your credit file, so you don’t want to be firing off applications everywhere. That’s another reason to start with a repricing request to your current bank, and to let a broker target the right lender if you do switch.
How often should I review my home loan?
At least once a year, and always in the six months before a fixed rate ends. Rates and lender appetites shift constantly — a loan that was competitive when you signed up can quietly fall behind.
Is switching really worth the hassle?
Often, yes — and increasingly, you don’t even have to switch. Getting your current lender to reprice can capture most of the saving with almost none of the effort.
The bottom line
The loyalty tax works because it’s invisible. Banks are betting you won’t check, won’t ask, and won’t move — and for most people, that bet pays off. The moment you show you’re paying attention, the maths changes.
You shouldn’t have to threaten to leave to be treated fairly. Let us do the checking for you: we’ll tell you honestly whether you’re on a good rate, and if you’re not, we’ll fix it — ideally without you having to change banks at all.
