If you’ve had your home loan for more than a year or two, there’s a decent chance you’re paying more interest than you should be.

Not because you made any mistakes when you took it out, but because home loans don’t stay competitive on their own. Someone needs to watch them.

This one’s for homeowners and anyone thinking about refinancing. We’ll walk through the warning signs, what actually matters, and when it’s worth doing something about it.

Know your actual rate (not the one you think you’re on)

This sounds basic, but it’s where most people get stuck.

Your interest rate might not be the rate you signed up for. It might not be the rate on your lender’s website. And it’s definitely not the rate your mate got last year.

The only rate that matters is the one you’re paying right now.

What to do: Pull up your latest loan statement or log into your online banking. Look for your current interest rate and whether it’s variable, fixed, or split. If you haven’t checked in six months, you’re guessing. And guessing costs money.

A lot of people remember the rate they started on and assume it’s still roughly the same. But lenders adjust rates all the time, sometimes monthly. If you took out a loan in 2022 on a certain rate, there’s almost no chance you’re still on that exact number today unless it was fixed and the fixed term hasn’t ended yet.

Even if your rate has moved, it might not have moved as much as the market has. That’s the gap that costs you.

Compare your rate to what’s actually available

When you hear “rates are dropping” or “rates are high”, that’s usually about new customer offers, advertised headline rates, or best case scenarios with tight pricing.

What you should compare instead is your loan type (whether it’s owner occupied or investment), your LVR (which is roughly what you owe versus what the property’s worth), and whether you’ve got features like offset or redraw.

Here’s a rough guide: If your rate is 0.50% above what similar borrowers are getting today, it’s worth a look. If it’s 1.00% or more higher, you’re almost certainly overpaying.

The tricky part is knowing what “similar” actually means. A $400,000 loan at 80% LVR with an offset account should be compared to other loans with the same structure, not to a no frills basic variable with no features. Apples to apples matters here.

And don’t just compare to the flashy advertised rates. Those are often conditional: minimum loan size, specific LVR bands, new customers only. What you want to know is what’s realistically available to someone in your situation.

The loyalty tax is real

Lenders sharpen their pencils for new customers. They don’t always do the same for existing ones.

You’re probably paying the loyalty tax if your rate hasn’t moved in years, you’ve never asked for a review, you took out a good deal a few years back but never followed up, or your lender hasn’t reached out proactively.

This isn’t about your lender being dodgy. It’s just how the system works. The people who review regularly come out ahead.

Banks operate on the assumption that most customers won’t ask. They price aggressively to win business, then quietly let those customers drift into less competitive pricing over time. It’s not personal, it’s business. But it also means the onus is on you to stay across it.

The other side of this is that banks do have room to move when you ask. Retention is cheaper than acquisition, so if you’ve been a good customer and you’re genuinely considering leaving, they’ll often sharpen the pencil to keep you. But you have to ask. They won’t just hand it over.

Look at your repayments, not just the number

Even small rate differences add up fast.

Quick example: A $600,000 loan with a 0.75% rate difference costs you roughly $4,500 extra per year in interest. That’s money walking out the door for no benefit.

If your repayments feel heavy relative to what you owe, that’s usually the first sign something’s off, even before you crunch the numbers.

Over the life of a 30 year loan, that 0.75% difference compounds into tens of thousands of dollars. Most people don’t feel it month to month because the difference might only be a few hundred bucks per month. But those hundreds add up, and they add up faster than you think.

It’s also worth looking at how much of your repayment is actually hitting the principal versus just covering interest. If you’re a few years into your loan and the principal isn’t dropping as quickly as you expected, that’s another flag. It doesn’t always mean your rate is bad, it might just mean your loan term or repayment structure isn’t working efficiently.

Make sure your loan still fits how you actually use money

Overpaying isn’t always about the rate itself.

You might be paying too much if you don’t have an offset but keep savings sitting elsewhere. Maybe you’re on a basic loan paying a premium rate. There’s also the people on feature packed loans who aren’t using any of the features. And sometimes your loan structure just doesn’t match your income or goals anymore.

A loan that made sense three years ago can quietly become inefficient as your situation changes.

Here’s a common one: You took out a loan with a package that included offset, redraw, and extra repayment flexibility. You’re paying a rate that reflects those features, usually 0.20% to 0.40% higher than a basic loan. But you’re not using the offset. You’re not making extra repayments. You’re just paying the minimum each month.

In that case, you’re paying for features you’re not using. You might be better off on a cheaper product without the bells and whistles.

The reverse is also true. Maybe you took out a basic variable because the rate was sharp, but now you’ve got a decent chunk of savings and no offset to park them in. You’re paying tax on that savings account interest while still paying full interest on your loan. That’s inefficient.

Your loan needs to match your actual behaviour, not your intentions.

Ask yourself one honest question

“If I applied for this loan today, would it still be the best option?”

If your answer is “not sure”, it’s time to review it. If it’s “probably not”, definitely review it. And if it’s “no idea”, that’s your answer.

A review doesn’t always mean refinancing. Sometimes a rate negotiation sorts it. Other times the market genuinely has better options.

The point is knowing, not guessing.

Most people avoid this question because they assume reviewing their loan is complicated or time consuming. It’s not. A proper review takes an hour, maybe two if your situation’s complex. What takes longer is avoiding it and then realising years later you’ve been overpaying the whole time.

And here’s the thing: reviewing doesn’t lock you into anything. You’re not committed to switching just because you asked the question. You’re just getting the information you need to make a decision. That’s it.

What a review actually looks like

If you’ve never done a loan review before, here’s what it involves.

You pull together your current loan details: balance, rate, repayments, features. You look at what else is available in the market for someone in your position. You compare the two. Then you decide whether the gap is worth acting on.

Sometimes the answer is no. Your loan’s competitive, your lender’s been fair, and switching would cost more in time and fees than you’d save. That’s fine. At least you know.

Other times the gap is obvious. You’re paying 1.50% more than you should be, and refinancing would save you $8,000 a year. In that case, it’s a no brainer.

The bit that trips people up is the middle ground, where the difference is 0.40% or 0.60%. Is that worth switching for? Depends on your loan size, how long you plan to stay in the property, and what the refinancing process looks like for you.

That’s where a broker helps. We run the numbers, factor in the costs, and give you a straight answer on whether it makes sense or not. No sales pitch, no pressure, just the maths.

When it’s worth switching vs when it’s not

Refinancing isn’t always the right move, even if you’re overpaying.

It’s usually worth it if:

  • The rate difference is 0.50% or more
  • You’ve got at least two years left on your loan
  • Your property value is stable or has gone up
  • You’re not planning to sell in the next 12 months
  • The new loan genuinely suits your situation better

It’s probably not worth it if:

  • You’re within 12 months of paying off the loan
  • You’ve got an active fixed rate with big break costs
  • Your property value has dropped and your LVR is now too high
  • The difference in rate is tiny and the refinancing costs eat up the savings

Every situation’s different, but those are the general guidelines.

The other factor is your time and energy. Refinancing takes a bit of effort: applications, paperwork, settlement. If you’re in the middle of something big (new job, new baby, interstate move), it might not be the right moment even if the numbers stack up. That’s okay. Just don’t let it drift for years.

Final word

Interest creep is silent. It doesn’t send alerts. It doesn’t show up as a line item you notice day to day.

But over years, it’s one of the biggest leaks in household budgets.

The smartest borrowers aren’t constantly switching loans. They’re checking regularly and acting when it makes sense. They’re not precious about their lender. They’re not loyal to a brand. They’re loyal to their own financial position.

If you’re not sure where you stand, you’re not alone. Most homeowners are in the same spot. They’ve got a vague sense their rate might not be great, but they don’t know how to check or what to do about it.

That’s what we do. We take a look at your loan, compare it to what’s available, and tell you straight whether you’re paying too much or sitting where you should be. No drama, no pressure, just a clear answer and a plan if you need one.
