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.

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.
