What refinancing really costs: break fees, LMI and traps

Refinancing your home or investment loan in Australia always comes with costs: discharge fees to leave your current lender, application and government fees with your new lender, and sometimes chunky fixed‑rate break costs or a fresh hit of Lenders Mortgage Insurance (LMI). The real question is whether those costs are outweighed by lower interest and a better structure over the next few years.

In practice, refinancing costs in Australia usually range from a few hundred dollars in basic fees to many thousands when fixed break fees or new LMI are involved. To decide if it’s worth it, you need to identify every cost, estimate your interest savings, and work out how long it takes to “breakeven” — then only move if that timeline suits your plans.

If you haven’t yet looked at the broader picture of when and why to refinance, it’s worth reading this alongside our guide on how to decide when refinancing makes sense.

Start by listing every fee your current and new lenders will charge.

1. Start with the real question: will you be better off?

Before drilling into break fees and LMI, anchor everything to one test: after all costs, will you be clearly better off over the period you’re likely to keep the new loan? For most people, that’s 3–5 years, not the full 30‑year term.

A simple breakeven example

Say you have:

• Current loan: $700,000, 25 years remaining
• Current rate: 6.60% p.a. (principal and interest)
• New rate on offer: 5.90% p.a. (principal and interest)

Indicative repayments:

• At 6.60%: about $4,750 per month
• At 5.90%: about $4,467 per month

So you’d save roughly $283 per month, or about $3,400 per year, before costs.

Now assume typical costs to refinance:

• Discharge fee with current lender: $350
• New lender’s settlement / legal fee: $400
• Government registration fees: $300
• Valuation fee: $400 (if not covered by the lender)

Total upfront cost: $1,450.

Breakeven time: $1,450 ÷ $283 ≈ 5.1 months. If you plan to keep the property and loan structure for at least a few years, that’s a pretty clear win.

Once you layer in potential break fees on a fixed loan or new LMI, that breakeven can blow out to years — which is where people get caught.

For a full process on how to do this comparison across multiple scenarios, see our broader practical guide to refinancing costs, risks and process.

2. Common upfront refinancing costs in Australia

Most borrowers will face at least some version of these fees when switching lenders.

2.1 Discharge and settlement fees

These are charged by your current lender to release their mortgage over your property and close the loan.

Typical ranges (illustrative):

• Discharge / termination fee: $150–$400 per loan
• Settlement / production of title fees: $0–$300

If you have multiple loan splits or properties, these can stack up because fees are often per account or per title.

2.2 New lender application and ongoing fees

Your new lender may charge:

• Application / establishment fee: $0–$600 (some waive this for promotions)
• Settlement / legal fee: $0–$500
• Annual package fee (if using a package): about $300–$400 per year

Zero‑fee refinance deals often exist, but compare the interest rate and features. A slightly higher rate can cost far more than a one‑off application fee over time.

2.3 Government mortgage registration fees

State and territory land titles offices charge to register the new mortgage and remove the old one.

• Typical registration and discharge charges: around $200–$400 per property (varies by state/territory)

These are unavoidable; they apply even if you refinance with the same lender under a completely new loan number.

2.4 Valuation fees

Many lenders cover one standard valuation for refinances, but not all. And if your property is unusual, rural or high‑value, you may pay out of pocket.

• Standard metro valuation: $0–$500 (often rebated)
• Specialised / prestige / non‑standard security: can be higher

Valuations matter because they determine your loan‑to‑value ratio (LVR) — and therefore whether you tip over the 80% line and into LMI territory.

2.5 Rate‑lock fees (for fixed rates)

If you’re fixing all or part of your new loan, lenders often charge a rate‑lock fee so the fixed rate is guaranteed between approval and settlement.

• Typical rate‑lock fee: often around 0.10–0.20% of the fixed portion, or a set fee (e.g. $500–$1,000), depending on lender policy

Whether this is worth it depends on how volatile fixed rates are and your risk appetite.

Weigh break costs and LMI against realistic interest savings over time.

3. Break costs on fixed and package loans

For many borrowers, break costs are the big unknown — and where the worst surprises live.

3.1 What are break costs?

Break costs (sometimes called economic costs) are charged if you end a fixed‑rate period early or drastically change the loan (for example, large extra repayments or switching to variable before the fixed term ends).

They’re meant to compensate the lender for the difference between the interest they expected to earn and what they can now earn in wholesale markets. That means break costs can be very sensitive to interest rate movements, particularly after rapid RBA cash rate changes.

Exit fees on variable rate home loans were banned for new loans from 1 July 2011, but fixed‑rate break fees are still allowed.

3.2 When do break costs apply?

You might face break costs if you:

• Refinance to a new lender during a fixed period
• Switch from fixed to variable with your current lender
• Make extra repayments beyond the lender’s allowed limit
• Fully repay the loan (e.g. after a sale) before the fixed term ends

Always ask your current lender for a break cost estimate in writing before you start a refinance.

3.3 How big can fixed break costs be?

The exact calculation is complex and lender‑specific, but a rough illustration helps.

Assume:

• Fixed loan balance: $500,000
• Fixed rate remaining term: 2 years
• Your fixed rate: 2.29% p.a.
• Current wholesale rate for remaining term: 4.50% p.a.

In this scenario, market rates are higher than your fixed rate. That usually means little or no break cost, and in some cases, a small adjustment in your favour.

Reverse it:

• Your fixed rate: 5.00% p.a.
• Current wholesale rate for remaining term: 3.50% p.a.

Now rates are lower than your fixed rate, so breaking early can trigger a large cost — sometimes many thousands of dollars, depending on remaining term and balance.

It’s not unusual to see fixed break costs run into the $10,000–$30,000+ range on sizeable loans fixed at significantly above current market rates.

3.4 Should you ever pay a big break cost to refinance?

Sometimes, yes. If you’re sitting on an uncompetitive fixed rate with years left to run, and your loan is large, a sharp rate cut plus better structure can still be worth it.

You’d run the same breakeven logic:

1. Get a written break cost quote from your lender.
2. Add all other refinance fees.
3. Calculate interest savings over 3–5 years at the new rate.
4. Only proceed if savings exceed costs comfortably within the time you expect to keep the loan.

A broker who understands both home and investment structures can also explore options like keeping part of the fixed loan and refinancing only the variable portions.

4. Lenders Mortgage Insurance (LMI) when you refinance

LMI is a major line item that can make or break the case for refinancing.

4.1 When does LMI apply on a refinance?

LMI usually kicks in when your new loan is above 80% LVR. On owner‑occupied loans some lenders may go to 85% without LMI, and on certain schemes or professions you might get more flexibility, but as a rule of thumb:

• ≤80% LVR: no standard LMI

• 80% LVR: LMI generally applies, unless a government guarantee or other exemption is involved

If property values have softened or you’ve topped up the loan over time, you may find that refinancing to a new lender triggers LMI, even if you didn’t pay it originally.

4.2 Can you transfer your existing LMI?

In most cases, no. LMI is a policy between the lender and the insurer, not you personally. When you move lenders, the new lender will usually require a new LMI policy based on current LVR and their insurer’s premiums.

Sometimes you can get partial relief if you refinance within a short timeframe and your new lender uses the same LMI provider, but this is the exception rather than the rule.

4.3 How much can LMI cost on a refinance?

LMI premiums grow quickly once you go above 80% LVR.

Indicative example:

• Property value: $800,000
• Loan at 90% LVR: $720,000

An LMI premium on a 90% LVR loan of $720,000 can easily be in the $15,000–$20,000+ range, depending on the lender and your profile. It’s often capitalised into the loan (added to the balance) rather than paid in cash, meaning you pay interest on it for years.

That’s why staying under 80% LVR generally unlocks lower pricing and avoids LMI altogether — a principle that holds for both new loans and refinances.

4.4 Strategies to avoid or reduce LMI when refinancing

If you’re close to 80% LVR, there are levers you can pull:

• Extra repayments before refinance to push LVR below 80%
• Seeking a lender with a sharper valuation (without inflating figures)
• Reducing the refinance amount by paying down other debts separately
• Using a family guarantee (where appropriate and fully understood)

If none of that keeps you below 80% LVR, weigh the upfront LMI cost against:

• The rate difference
• The loan size
• Your future plans (holding period)

Only swallow a new LMI hit if the numbers stack up over a realistic timeframe.

For a wider breakdown of when LMI is worth it versus when it’s just a drag, see our refinancing costs, risks and process guide.

5. Less obvious refinancing “gotchas” that quietly cost you

Beyond obvious line‑item fees, there are structural and timing traps that can quietly erode your benefit.

5.1 Extending your loan term and paying more interest overall

Many refinances reset the clock back to 25 or 30 years, even if you’ve already paid off a chunk of term.

Example:

• Existing loan: $600,000, 20 years remaining, 6.40% p.a.
• New loan: $600,000, 30 years, 5.90% p.a.

Your monthly repayment falls, but because you’re paying over 30 years instead of 20, total lifetime interest may still be higher despite the lower rate.

You can avoid this by asking the new lender to match your remaining term or set a shorter term on the main home loan split, then using offsets for flexibility.

5.2 Cashback offers that cost more than they save

Cashback offers of $2,000–$4,000 to refinance can look tempting. But if the cashback lender’s interest rate is 0.20–0.30% higher than the sharpest competitor, you can easily “repay” that cashback through higher interest within a few years.

Always compare:

• Net upfront cash (cashback minus all fees)
• The rate and features you’re accepting for the next 3–5 years

Free money is only free if the structure and pricing are still competitive.

5.3 Double interest in the changeover period

If settlement timing is messy, you can briefly pay interest on both loans at once — especially if your old lender is slow to discharge.

Careful coordination between broker, solicitor and both lenders can reduce this risk. Aim for same‑day settlement and keep surplus funds ready to clear any overlap.

5.4 Losing good features or sabotaging your tax position

Cheaper is not always better if you lose valuable features such as:

• Multiple loan splits to separate home, investment and personal purposes
• An offset account linked to your non‑deductible home loan
• Flexible redraw limits or construction / renovation features

For investors and self‑employed clients, collapsing everything into one big loan can also blur what’s deductible and what’s not. Keeping separate splits by purpose makes later refinancing, selling and tax advice far easier.

5.5 Extra hurdles for self‑employed borrowers

If you’re self‑employed, lender policy and documentation pathways matter as much as price. A move from alt‑doc to full‑doc once your tax returns are strong can cut your rate significantly, but switching too early could leave you stuck with higher pricing or a decline.

Our guide on documentation pathways for home loans and the self‑employed refinancing timing guide walk through how to time this correctly.

5.6 Serviceability buffers and “no” after you’ve already paid fees

Most lenders assess your ability to repay at about 3% above the actual rate, in line with APRA guidance. That means if you’re tight on borrowing capacity, you can pay for valuations and other costs only to be knocked back late in the process.

A good broker will run realistic serviceability tests before you commit to a specific lender, including for any future debt consolidation or equity release.

Good structuring can save interest and avoid future refinancing headaches.

6. Stay or switch? A comparison over three years

Here’s a simplified snapshot of how costs and savings can play out over three years for a typical owner‑occupied loan.

Assumptions (illustrative only, not advice or live rates):

• Current balance: $650,000, 25 years remaining
• Current rate: 6.60% p.a. (stay scenario)
• New lender sharp rate: 5.90% p.a.
• LVR at new lender: 78% (no LMI scenario) or 87% (LMI scenario)

This table shows three important points:

1. Sometimes a reprice with your existing lender almost matches the benefit of a full refinance without any costs.
2. A clean no‑LMI refinance can deliver strong savings after a relatively short breakeven period.
3. Once you add a large new LMI premium, the advantage can shrink materially — or disappear altogether if your rate gap is smaller.

That’s why it’s critical to run these numbers before you get seduced by a headline rate or cashback.

7. A quick way to run the numbers this week

If you’re time‑poor, here’s a practical process you can complete in a couple of evenings.

7.1 Pull together the key data

From your current lender:

• Loan balance(s) and remaining term
• Current rate(s) and repayment type (P&I vs IO)
• Fixed/variable breakdown and fixed‑rate expiry dates
• Any package, offset or annual fees

7.2 Get written cost and break fee estimates

Ask your current lender for:

• A payout figure for a settlement date around 60 days away
• Any fixed‑rate break costs if you exit or vary early
• Confirmation of discharge / settlement fees per loan

From a broker or prospective new lender, get:

• Indicative rate and product options
• Estimated application / settlement fees
• Whether valuations and rate‑lock are free or charged

7.3 Estimate interest savings

Use a reputable calculator or have your broker run scenarios:

• Current repayment and 3‑year interest cost at your existing rate
• New repayment and 3‑year interest cost at each proposed rate

Subtract: current 3‑year interest – new 3‑year interest = gross saving.

7.4 Net off every cost

Add together:

• Old lender discharge and settlement fees
• New lender application and settlement fees
• Government registration fees
• Any rate‑lock cost
• Any new LMI premium (even if capitalised)
• Estimated fixed break costs

Compare this sum to your 3‑year gross saving.

7.5 Decide based on your plans

Refinancing is usually more compelling if you:

• Expect to keep the property for at least 3–5 years
• Are not planning major structural changes (e.g. selling or big equity release) soon
• Can maintain or shorten your remaining loan term, rather than stretching it

If you’re likely to sell or significantly restructure within 1–2 years, the maths often favours negotiating harder with your current lender instead of switching.

8. When paying these costs still makes sense — and when it doesn’t

8.1 When paying to refinance is usually worth it

Refinancing costs are more likely to pay for themselves when:

• Your rate is clearly uncompetitive and the gap is at least 0.40–0.60% on a sizeable balance
• You have more than 10 years left on the loan and plan to hold the property
• You can avoid new LMI by keeping LVR at or below 80%
• You’re moving from alt‑doc to full‑doc with stronger financials, unlocking much sharper pricing
• You’re cleaning up messy structures: consolidating consumer debts into a shorter‑term split, separating home and investment loans, or isolating business borrowing

In these cases, a few thousand dollars in costs can unlock tens of thousands in long‑term savings and a safer structure.

8.2 When staying or just repricing is usually better

Refinancing may not stack up if:

• Your loan balance is modest (e.g. under $250,000) with less than 5–7 years remaining
• You’ll trigger large new LMI for only a small rate advantage
• Fixed break costs are significant and your fixed period ends relatively soon
• You expect major life changes (sale, separation, relocation, business restructure) in the short term

In those cases, pushing your existing lender for a rate review or minor restructure can be safer than a full refinance.

For borrowers juggling home and business needs, our guide on when business growth means you’ve outgrown your old home loan can help you decide if a structural overhaul is worth the effort.

Key takeaways

• Refinancing costs range from a few hundred dollars in basic fees to tens of thousands where fixed break costs and new LMI premiums apply.
• The right way to decide is to compare 3–5 years of interest savings against every cost, not just chase the lowest headline rate.
• Staying above 80% LVR often drags in new Lenders Mortgage Insurance, which can materially reduce or wipe out the benefit of switching.
• Extending your term back to 30 years can quietly increase total interest paid, even if your new monthly repayment is lower.
• Cashback offers, poor timing and loss of useful loan features are common traps that can leave you no better off after refinancing.
• Self‑employed and multi‑property borrowers need to be especially deliberate about timing, documentation pathway and structure before they move.

If you’d like a decision‑grade view of your own numbers — including all the hidden costs and the realistic breakeven period — a broker who understands both residential and business lending can run the scenarios and help you choose whether to switch or stay put.
