You and your neighbour share the same street, the same local bank branch, and both signed up for a variable mortgage on the same day. Yet when you compare monthly statements, one of you is paying significantly more in interest. How is that possible with a “standard” product?
The Starting Point — The Standard Variable Rate (SVR)
Every variable home loan starts at a publicly advertised rate known as the Standard Variable Rate (SVR). Think of it as the bank’s base price — a mass pricing tool that allows lenders to adjust thousands of loans simultaneously in response to RBA decisions or market shifts.
But here’s what the brochure doesn’t tell you: the SVR is almost never what you actually pay.
The Formula Behind Your Real Rate
What you pay each month is determined by a simple but powerful equation:
Your Effective Rate = SVR − Your Personalised Discount
That discount is shaped by a combination of factors that together form your “discountable profile”:
- Loan-to-Value Ratio (LVR): Lower LVR means more equity and less risk — rewarded with a larger discount
- Loan Size: Higher balances represent greater value to the bank — often attracting better pricing
- Credit History: A clean record signals low default risk — worth more discount
- Relationship Depth: Banking products consolidated in one institution increase your lifetime value
- Market Competition: Active comparison and willingness to switch signals to lenders you’re paying attention
The Loyalty Tax: Why Silence Is the Most Expensive Mistake
Here’s the counterintuitive reality of the mortgage market: banks offer their deepest discounts to new customers. Introductory rates are used to attract borrowers away from competitors. Long-term, passive customers — those who assume the bank is looking after them — are frequently left on higher effective rates.
This is the “Loyalty Tax.” It’s the premium you pay for staying quiet.
Research confirms that customers within the same bank, on the same loan product, can be paying materially different interest rates — the only difference being how actively they engaged with their lender.
What This Means for You
On a $600,000 loan, a 0.75% difference in effective rate translates to a significant cost over the life of the loan. The gap between a proactive borrower and a passive one isn’t just a number on paper — it compounds every single month.
Your interest rate is not a fixed decree. It is a reflection of your perceived value and your willingness to speak up.
Taking Action
If you’ve never reviewed your rate since your loan settled, chances are there’s room to improve your position. A mortgage broker can assess your current effective rate against current market pricing across multiple lenders — helping you understand whether your discount reflects your true financial profile.
The best rate doesn’t go to the most loyal customer. It goes to the most informed and vocal one.
