Negative Equity on Your Car Loan: What It Means, Why It Happens, and How Australians Can Avoid Getting Trapped

What Is Negative Equity on a Car Loan?

Negative equity — sometimes called being "upside down" or "underwater" on your loan — happens when your car is worth less than the amount you still owe on it. The maths is brutal and simple: if your loan balance is $28,000 but your car would only sell for $21,000 today, you have $7,000 in negative equity. You own the car, but the car doesn't own itself — the bank does, and then some.

It sounds like an edge case. It isn't. Used car values that were inflated during the supply-chain crunch of 2021–22 have softened significantly since then, leaving a wave of Australians who financed at peak prices now sitting on loans that are worth more than the metal in their driveway. And the problem compounds: the longer your loan term, the more of your early repayments go to interest rather than principal, which means your equity position barely moves in the first year or two.

How Does Negative Equity Actually Happen?

It usually starts on the day you drive out of the dealership. New cars can lose significant value the moment they leave the lot, and if you financed close to 100% of the purchase price, you're often in negative equity from day one before you've even missed a repayment. Here are the specific traps that make it worse:

• No deposit or a small deposit. The less you put in upfront, the more you borrow — and the more exposed you are when the car drops in value. Financing the full purchase price means you owe more than the car's worth almost immediately.
• Long loan terms. A 5–7 year loan stretches your repayments so low they feel manageable, but most of that early cash goes to interest, not reducing your principal. Your loan balance barely budges while the car depreciates hard.
• Rolling in extras. Dealers love bundling accessories, extended warranties, and insurance products into your loan amount. A $3,000 bull bar or a $2,500 paint protection package sounds like nothing — but you're paying interest on those extras for the life of the loan.
• Buying at peak used-car prices. Australians who bought popular models like the Toyota RAV4 or Ford Ranger at 2022 prices are now commonly in negative equity as used car values have retreated sharply from those highs.
• Rolling old negative equity forward. This is the sneakiest trap of all. You trade in a car where you owe more than it's worth, and the dealer quietly folds the shortfall into your new loan. Suddenly you owe $27,000 on a $25,000 car before you've even driven away.

What ASIC Found in June 2026 — and Why It Matters

This isn't just personal finance theory. In June 2026, ASIC released Report 832 — Lifting the Bonnet: ASIC's Review of Car Loans — and the findings are uncomfortable reading for anyone who got their finance through a dealership. ASIC examined data from over 350,000 loans across eight of Australia's largest car finance providers. What they found: significant shortcomings in how lenders oversee the dealers and brokers who sell their loans. In plain English, lenders were letting dealers do what they liked with little accountability for the outcomes borrowers ended up with.

The report also highlighted real cases of harm — including lenders repossessing cars after rejecting hardship assistance requests, leaving borrowers with debt and no car. When your car gets repossessed while you're in negative equity, you still owe the shortfall. You lose the car and the debt follows you. ASIC Commissioner Alan Kirkland was direct: "Responsibility for consumer outcomes cannot be outsourced." That's a regulator telling the finance industry it's been passing the buck — at your expense.

The Real Rate You're Paying (Not the One on the Poster)

Here's a figure that should stop you mid-scroll: the Reserve Bank of Australia reports the average fixed-term personal loan rate — which includes car loans — is currently 9.06% p.a. Compare that to the 5.66%–5.94% rates you'll see advertised, and you start to understand the gap between the marketing and the reality. Most Australians don't get the headline rate. Your actual rate depends on your credit profile, whether you own property, and frankly, how much the dealer's finance manager wants to make on the deal.

At 9% on a $35,000 loan over 5 years, you're paying approximately $9,300 in interest over the life of the loan. Reduce that rate to 6.5% and you save around $4,200. That's real money. But very few people walk into a dealership knowing to fight for it.

The ATO Update You Should Know About From 1 July 2026

If you use your car for work, there are a couple of fresh numbers worth knowing heading into the new financial year. From 1 July 2026, the ATO has increased the cents-per-kilometre rate to 91 cents per kilometre (up from 88 cents), meaning you can now claim up to $4,550 in car expense deductions without keeping a logbook — just multiply 5,000km by 91 cents. That's a small but real improvement for anyone using their personal car for work purposes.

For business owners and self-employed Australians, the car depreciation limit for the 2026–27 financial year is now $69,883. If you finance a vehicle above that value for business use, you can only claim depreciation up to that cap — a detail that matters when you're structuring a loan. Always speak to a financial adviser or registered tax agent about how these thresholds apply to your specific situation.

What Happens When You Try to Sell or Trade In?

This is where negative equity stops being theoretical and starts costing real money. If you want to sell your car privately while you still owe more than it's worth, the sale won't fully cover the loan. You'll need to make up the difference yourself. And if you're trading in at a dealership, there's a very good chance the finance manager will offer to "help" by rolling your negative equity shortfall into your next loan — making your new loan start underwater before you've signed anything.

The PPSR (Personal Property Securities Register) is the other thing most Australians don't know about. When you take out a car loan, the lender registers a security interest against the vehicle on the PPSR. That security interest stays with the car — not the seller — until the loan is formally discharged. If someone buys a car from you without knowing there's finance outstanding, the lender can legally repossess the vehicle from the new owner. This is why any sale of a financed vehicle must clear the loan as part of the transaction.

How to Avoid Getting Trapped in Negative Equity

There's no magic fix, but there are clear moves that reduce your exposure:

• Put down a real deposit. Even 10–15% upfront changes your equity position from day one and gives the car's value room to depreciate without pulling you underwater.
• Choose a shorter loan term. A 3-year loan costs more per month but puts you in a positive equity position much faster. A 7-year loan feels cheaper weekly but leaves you exposed for years.
• Don't roll in the extras. If a dealer wants to bundle accessories, warranties, or add-on insurance into your loan, ask to see the total interest cost of doing so over the loan term. Often, paying separately or skipping the extras entirely is the smarter call.
• Don't roll old debt forward. If you owe more on your current car than it's worth, deal with that shortfall before financing your next one. Rolling it into a new loan just guarantees you start the next chapter underwater too.
• Check your loan balance vs. car value regularly. You can get a trade-in appraisal at a dealership, use an online valuation tool, or ask an independent valuer. Knowing your equity position keeps you in control of your options.
• Compare rates before you sign anything. The finance desk at a dealership is not your friend when it comes to rate shopping. Getting pre-approved from a bank, credit union, or non-bank lender before you visit the lot gives you leverage and a benchmark rate to measure the dealer's offer against.

What Milam Does Differently

Most car finance products leave you with nothing at the end — you've paid down the loan, you hand back or sell the car, and that's it. No equity payout. No share of the car's residual value. Just years of repayments and a handshake goodbye. Milam works differently. With Milam's model, customers get lower weekly payments and an equity payout when they return the car — so you actually walk away with something in your pocket, not just a folder of receipts. It's a fundamentally different approach to the question: what do I actually get out of this?

In a world where ASIC is warning about lender misconduct, where the average car loan rate is sitting nearly 4 percentage points above advertised lows, and where negative equity is quietly trapping thousands of Australians, the most powerful thing you can do is understand the game being played — and choose a product that's actually designed to work in your favour.
