Australia Is Buying EVs at Record Speed. Here's Why Picking the Wrong Finance Could Cost You $15,000.

The EV Sales Boom Is Real. The Finance Trap Is Realer.

Let's start with the numbers, because they are genuinely staggering. In June 2026, 140,058 new vehicles were sold in Australia — the strongest June on record. The Tesla Model Y alone moved 8,072 units in a single month, an all-time record, outselling the Ford Ranger and the Toyota HiLux. BYD sold 18,881 vehicles in June — just 243 cars fewer than Toyota. EVs and plug-in hybrids hit 35.8% of new passenger car sales for the month. At the same point last year, EVs were just 11% of new vehicle sales. That's not growth. That's a structural shift.

Australians are clearly excited. But excitement is exactly when you need to slow down and read the fine print on your finance contract. Because the same EV market that's booming in the showroom has a dirty secret in the used-car lane — and if your finance deal doesn't account for it, you're the one who pays.

The Depreciation Problem Every EV Buyer Needs to Know

Here's a number that should be required reading before you sign anything: a one-year-old electric vehicle in Australia loses an average of 25% of its value. By comparison, a one-year-old petrol car loses about 11.5%. Hybrids? Just 1.7%. That's not a small gap — it's a chasm.

The data gets more confronting when you zoom in on specific models. The Chery Tiggo 7 Pro dropped 42% in value in just over a year. The BYD Atto 3's 2024 model depreciated 35.84%. And the Tesla Model Y RWD from 2022? Its value was almost halved — a 48.93% depreciation rate — driven largely by Tesla's own aggressive price-cutting strategy between 2023 and 2024.

That last point is crucial, and it's one most finance companies don't want to talk about. When Tesla slashed the Model Y's price to $55,900, every used Tesla on the market dropped in value overnight. The manufacturer controls the new-car price. You, sitting in your driveway with a 2-year-old EV and a loan still running, have zero control. You just watch the equity evaporate.

The RBA Has Rates on Hold — But That's Not the Whole Story

The RBA held the cash rate at 4.35% at its June 2026 meeting, and the next decision isn't until 11 August. That sounds like stability — but context matters. The RBA has raised rates three times already in 2026, driven by an energy shock and persistent inflation running well above the 2–3% target. The RBA has explicitly said further tightening remains possible. Meanwhile, big four banks are now questioning whether rate cuts will even arrive before mid-2027.

What does this mean for your car loan? It means the interest rate environment is not your friend right now. The comparison rate on a standard car loan from a dealer — once you factor in establishment fees, monthly fees, and that sneaky dealer commission baked into your rate — can sit materially higher than the headline number. ASIC's Report 832, published in June 2026 after reviewing over 350,000 car loans, found establishment fees of up to $9,000 on a single loan. That's 18% of an average loan amount — added to your principal, so you pay interest on the fee for the full term. At 4.35% base rates, that's real money compounding against you every week.

So the Industry's Answer Is GFV. But Which GFV?

The car industry has spotted the depreciation anxiety and responded. In July 2026, Tesla and finance platform Driva launched a Guaranteed Future Value loan for Model Y and Model 3 buyers. Mazda followed almost immediately with its own GFV product, Mazda Assured, targeting first-time EV buyers specifically. The pitch from both: lock in a minimum resale value upfront, keep your repayments lower, and don't stress about what the car is worth at the end.

It sounds great. And structurally, a properly designed GFV loan is better than a standard loan for an asset that depreciates fast. But — and this is the part that gets quietly glossed over — not all GFV products are built the same. Here's what to look for:

• What happens to your equity if the car is worth MORE than the GFV? In a standard GFV loan, you return the car and walk away. If the market held and the car is worth $5,000 more than the guaranteed figure, who keeps that? With a Milam product, you keep it. With a standard dealer GFV? Read the fine print carefully.
• What are the mileage and condition conditions? Tesla and Driva's GFV only applies if the vehicle meets fair wear and tear guidelines and stays within an agreed annual kilometre limit. Go over those limits and the guarantee doesn't protect you the same way. That's a significant condition that most salespeople won't volunteer upfront.
• What's the actual residual figure — and who sets it? Nobody is publishing those numbers publicly yet. A conservative GFV set by the lender means they carry minimal risk and the 'guarantee' is more brand reassurance than genuine financial protection. Ask for the exact residual figure in writing before you sign anything.
• What are the fees? A GFV loan can still carry establishment fees, monthly fees, and a dealer commission embedded in the rate. The structure is better than a balloon loan — but the costs around it still matter.

The Thing That's Really Different About How Milam Approaches This

Standard GFV loans give you protection on the downside — if the car depreciates past the guaranteed amount, the lender wears it. That's genuinely useful. But most of them don't give you anything on the upside. You return the car, you get nothing back. You've been making repayments for three or four years, and you walk away with zero equity to put toward your next vehicle.

Milam is built on a different premise: you should get equity back when the car goes back. Lower weekly repayments than a standard loan, and an equity payout when the term ends — instead of handing the car back and walking away empty-handed. In a market where EVs can depreciate 25% in year one, the structure of your finance product isn't a minor detail. It's potentially a $10,000–$15,000 decision.

What You Should Actually Do Before Signing an EV Finance Deal Right Now

The EV market in Australia right now is a genuinely exciting place to be a buyer. More choice, better technology, and increasingly competitive pricing from brands like BYD, Kia, Hyundai, Polestar and Tesla. But the volume of Australians rushing into showrooms — 631,583 new vehicles sold in the first half of 2026 alone — means dealers are busier and less patient. That's a pressure environment. Don't make a $60,000 decision in a hurry.

• Get the residual figure in writing. Any GFV loan should tell you exactly what the car will be guaranteed at — before you sign, not after.
• Ask about mileage caps. If you drive 20,000km a year and the GFV assumes 15,000km, the guarantee may be materially weaker than you think.
• Get the comparison rate, not the headline rate. The headline rate is marketing. The comparison rate includes fees and is the number that tells you what the loan actually costs.
• Ask what happens to any equity above the GFV. If the car is worth more than the guaranteed figure at the end of the term, you should know upfront who benefits from that.
• Don't finance a car at a 4.35% cash rate environment using dealer finance without comparing alternatives first. In a high-rate environment, the spread between a well-structured product and dealer finance can be thousands of dollars over a 4-year term.

The Bottom Line

Australia's EV boom is real and it isn't slowing down. Record sales, record model diversity, and genuine competition finally driving prices down. But the finance market hasn't caught up with the asset class. EVs depreciate faster than petrol cars, the RBA's rate environment is not borrower-friendly, ASIC has just confirmed the industry is riddled with excessive fees and weak oversight, and most GFV products being sold in showrooms today protect the lender a lot more than they protect you.

Choose your finance product as carefully as you choose your car. The weekly repayment number on the showroom screen is designed to look affordable. What it doesn't show you is what you walk away with — or don't — at the end. That's the number that actually matters.
