One in Three Cars Sold in June Was Electric. Here's the Finance Trap Nobody's Talking About.

Australia's EV boom is real. The finance risk is realer.

Let's start with the facts on the ground. June 2026 was Australia's strongest June on record for new vehicle sales, with 140,058 units sold — up 9.88% on the same month last year. Battery electric vehicles didn't just show up to that party. They took it over, overtaking hybrids and diesel to become the second most popular drivetrain behind petrol for the month. BYD alone sold 18,881 vehicles in June — just 243 fewer than Toyota. The Model Y set an all-time sales record of 8,072 units in a single month.

This is not a niche trend. This is the Australian car market reshaping itself in real time. And wherever there's a gold rush, there's someone selling shovels — including finance products that look great on paper and get complicated when reality sets in.

What most EV buyers don't know about their finance deal

Most Australians financing a car in 2026 are using one of two structures: a Guaranteed Future Value (GFV) loan or a standard loan with a balloon payment. Both work on the same basic logic: a chunk of your car's value is deferred to the end of the loan term, which lowers your weekly repayments now. Sounds good. Here's the problem.

That deferred chunk — whether it's called a guaranteed future value, a residual, or a balloon — is calculated based on what the lender or manufacturer thinks the car will be worth in three to five years. For a petrol Toyota or a Ford Ranger, lenders have decades of data to work with. For a 2026 BYD Sealion, a Chery Omoda E5, or even a third-generation Tesla, that number is largely a guess.

And the guesses, so far, have not been great. Studies show that some EVs have depreciated by more than 50% over three years — compared to around 39% for a typical petrol vehicle over the same period. One analysis found that a 2021 EV initially priced at $52,800 was worth approximately $24,689 three years later — a 53% drop. If your GFV or balloon was set at 40% of the purchase price and the car is only worth 30%, you've got a problem that lands squarely on your lap.

Why the depreciation math is getting harder, not easier

Here's what's making this worse in 2026 specifically: volume. Australia's EV market grew 77.5% in the first half of the year. That means a massive wave of EVs bought in 2023 and 2024 — many through novated leases — are starting to come off their terms right now. More used EVs flowing into the market means more downward pressure on resale prices. One market analysis found that the off-lease supply wave is actively building and will continue to exert downward pressure through 2026–2027.

At the same time, technology keeps moving. Newer EV models arrive with better range, better software, and better batteries — which makes a 2023 model feel old faster than a 2023 petrol car ever would. That's not a criticism of EVs. It's just physics. And it's a genuine factor in residual value calculations that most dealers are not walking you through when they're handing you a pen.

The three scenarios that catch Australians off guard

1. The balloon payment you can't pay — and can't refinance

With a balloon payment loan, at the end of your term you either pay the balloon in cash, refinance it, or sell the car and use the proceeds to cover it. If the car's market value has dropped below your balloon amount — welcome to negative equity. You owe more than the car is worth, and you're back at the dealer starting from behind.

2. The GFV that protects the lender, not you

A standard GFV loan sounds safer because the lender guarantees a future value. But read the fine print carefully. That guarantee is conditional. Exceed the agreed kilometre limit, have any damage the lender deems excessive, or miss a service — and the guaranteed value can be voided. You hand the car back and still owe the difference. Meanwhile, if the car is worth more than the GFV, most lenders keep the upside. You get nothing.

3. The EOFY finance rush

June was Australia's biggest-ever month for new car sales — and that pressure is exactly the environment where bad finance decisions happen. Dealers are chasing manufacturer targets, short windows get advertised as urgent, and the finance office is where the real costs accumulate. One industry analysis found that EOFY finance office pressure — through extended warranties, interest rate markups, and add-ons — can total $8,400 or more in unnecessary costs. The car deal looks great. The finance deal quietly erases it.

What EV depreciation actually looks like in 2026

The good news is that the depreciation curve is not uniform. Mainstream models with strong brand recognition, wide service networks, and long battery warranties are holding value better. The average EV in early 2026 is holding roughly 55.5% of its value after 36 months — but that average masks a wide spread. Some models are well above that. Some are well below.

What drives better residual value in an EV? Battery condition, software support, manufacturer warranty coverage, broad buyer appeal, and established service infrastructure. A Tesla Model Y in 2026 has all of those. A brand-new entrant from a brand Australians haven't heard of yet — potentially not. And if you're financing that vehicle with a balloon or GFV, the lender's estimate of future value needs to account for all of that uncertainty.

The ATO angle (if you're buying for business)

For business owners buying an EV, there's an additional layer of complexity. The ATO car limit for 2026–27 is $69,883 — meaning that's the maximum value you can use to calculate depreciation, even if you pay more for the vehicle. If you buy a car above that threshold, you cannot claim depreciation on the excess. You also cannot claim a GST credit on the portion above the car limit. The ATO's cents-per-kilometre rate for 2025–26 sits at 88 cents per kilometre, capped at 5,000km. These thresholds matter enormously when you're choosing between a $68,000 EV and a $72,000 one — but the dealer will rarely bring them up unprompted. Speak to a financial adviser or your accountant before signing anything.

What Milam does differently — and why it matters here

The core problem with most EV finance in Australia right now is that the buyer carries all the residual value risk, and gets none of the upside. You make payments for three to five years, hand the car back, and walk away with nothing — or worse, walk away owing money because the residual was set too high.

Milam is built differently. Our structure gives you lower weekly payments and an equity payout when you return the vehicle — meaning if your car retains value, you actually benefit from that. You're not just a payment machine for someone else's asset. You're building something real. In a market where EV residual values vary wildly and lenders are still figuring out the pricing, that's not a small thing. It's the difference between a finance product that works for you and one that works against you.

Five questions to ask before you finance an EV in 2026

• What is the residual or balloon value, expressed as a dollar amount? Get it in writing. Don't accept a percentage without seeing the actual number.
• What happens if the car is worth less than that residual when the term ends? Who carries that risk — you or the lender?
• What conditions could void a GFV guarantee? Kilometre caps, damage clauses, and service requirements can all disqualify you.
• What is the total cost of the loan, including all fees? ASIC found establishment fees reaching $9,000 on a single loan — always ask for the full cost, not just the rate.
• If the car is worth more than the GFV at the end of the term, who keeps the difference? The answer to this question tells you everything about whose side the product is actually on.
