Why is my trade-in value so low? And should you sell separately?
Key takeaways
- A trade-in figure is a trade price, not a retail one. The gap pays for reconditioning, selling, holding the car, legal duties to the next buyer and market risk.
- Ask every dealer for two numbers in writing: the drive-away price with no trade-in, and the changeover with your trade. The difference is your real trade figure.
- Before you sign, read the contract's conditions on kilometres and condition. Photograph the odometer on appraisal day and again at handover.
- If you're GST-registered and used the car in your business, GST is generally one-eleventh of the trade-in value. Ask whether the figure includes it.
Your trade-in value is low because a dealer pays a trade price, not a retail one. The gap between the two pays for reconditioning, selling and holding the car, legal duties to the next buyer, and the risk that prices fall before it sells. A trade-in figure is also one number inside a bigger deal, so it can look higher or lower than what you’re really being paid.
Selling separately leaves you ahead only when an outright offer for your car beats the real trade figure inside the changeover quote. Here’s how to find that figure, and what can change it on delivery day.
Where does the gap between retail and trade go?
The price on a dealer’s windscreen is a retail asking price. Your trade figure is what the dealer can pay today and still make money once everything in between is done.
| Cost or risk | What it involves for the dealer |
|---|---|
| Reconditioning | Detailing, paint touch-ups, wheels, tyres and anything the appraisal found |
| Servicing and repairs | Bringing the logbook up to date and fixing faults before resale |
| Selling the car | Advertising, photos, sales staff and test drives |
| Holding the car | Yard space and the cost of money tied up until it sells |
| Market movement | Used prices can fall while the car waits for a buyer |
| Duties to the next buyer | Statutory warranty in some states, plus Australian Consumer Law protections |
| Profit | The margin that keeps the dealership running |
Two of these are easy to overlook. Used prices move week to week: industry data firm Datium Insights reported them down 3.1% in the week to 12 October 2026. A licensed dealer also takes on legal duties a private seller doesn’t. The ACCC says Australian Consumer Law protections apply to second-hand cars bought from a licensed dealer, but mostly not to private sales. In Victoria, for example, a licensed motor car trader must give a statutory warranty of 3 months or 5,000 km on used cars less than 10 years old that have travelled less than 160,000 km.
Fit matters too. A dealer already holding several cars like yours may pass your trade on to another dealer or an auction, and the trade figure may allow for that extra step.
None of this means every low trade figure is fair. It does mean a retail price is the wrong yardstick. Compare a trade figure with other real offers instead, as our guide on online valuations versus real offers explains.
How does a changeover price hide your trade value?
When you trade in, the number that matters is the changeover: the total you pay to hand over your car and drive away in the new one.
Because the changeover is a single figure, the dealer can split it between the new car’s price and your trade figure however it likes. Two splits look very different on paper.
- A generous trade figure and a small discount. Your trade looks great. The changeover may not be.
- A modest trade figure and a big discount. Your trade looks poor, even if the overall deal is good.
Either way, the trade-in figure on its own tells you very little. You need two numbers in writing: the new car’s drive-away price with no trade-in, and the changeover with your trade. Your real trade figure is the first number minus the second.
Watch the duty line as well. In Victoria, the State Revenue Office charges motor vehicle duty on the higher of the purchase price or the market value. In the Northern Territory, the dutiable value includes any trade-in allowance. In both, a new-car price lifted to show a bigger trade figure can mean paying more duty.
Worked example: finding the real trade figure in a changeover quote
The numbers below are made up to show the method. They aren’t valuations for any car.
Say you’re buying a new mid-size SUV and trading in your current car. Two dealers quote you.
| Line in the quote | Dealer A | Dealer B |
|---|---|---|
| New car, drive-away, with your trade | $54,990 | $52,490 |
| Trade-in figure shown | $31,000 | $28,000 |
| Changeover (what you pay) | $23,990 | $24,490 |
| New car, drive-away, no trade-in | $51,990 | $52,490 |
| Real trade figure (no-trade price minus changeover) | $28,000 | $28,000 |
Dealer A seems to pay $3,000 more for your car. It doesn’t. Both dealers are really paying $28,000 for it. Dealer A lifted the new car’s price by $3,000 to show a bigger trade figure. The only real difference is that Dealer A’s no-trade price is $500 lower, so its changeover is $500 better.
Now bring in an outright offer for your car from a separate buyer. If you buy from Dealer A with no trade-in, you pay $51,990, less whatever you sell your own car for.
- Outright offer of $29,500: your net cost is $22,490, which is $1,500 better than Dealer A’s changeover.
- Outright offer of $27,000: your net cost is $24,990, which is $1,000 worse than trading in.
So the outright offer has to beat the real trade figure, not the trade-in line on the quote, and by enough to cover any extra time or effort. To run the same check on your own quotes:
- Ask each dealer for the drive-away price with no trade-in, in writing.
- Ask for the changeover with your car traded in, also in writing.
- Subtract the changeover from the no-trade price. That’s your real trade figure.
- Get at least one outright offer for your car in the same week, so the market hasn’t moved between quotes.
- Check that every quote covers the same car, accessories and on-road costs, and the same choice of cash or dealer finance.
Can a dealer cut your trade-in value at delivery or after handover?
Before handover, it can happen. New cars can take weeks or months to arrive, and you keep driving the old one in the meantime. If your trade was appraised early, the dealer may look at it again on delivery day, so check whether your contract ties the trade figure to the car’s kilometres or condition at delivery.
The reasons that can fairly change a trade figure are much the same as for any offer.
- More kilometres than the contract allows for.
- New damage since the appraisal, such as a scrape or hail.
- A new warning light, or missing keys or service books.
- Anything the dealer wasn’t told about, such as past accident repairs.
Finance works a little differently. If there’s money owing on your trade, the dealer usually pays the lender out of the trade figure. A payout higher than the one the dealer worked from doesn’t change what your car is worth, but it does change how much you hand over on delivery day.
After handover is a different matter, because by then you should already have what you were promised. In Victoria, Consumer Affairs Victoria says a licensed motor car trader must pay you for your car, or provide the trade, before trying to sell it. It also tells sellers not to sign anything that transfers ownership until they’ve received their payment or trade. That’s sound practice in any state: don’t hand over the old car or sign its transfer until the new one is ready and the paperwork shows the trade figure you agreed.
If a dealer tries to reduce an agreed, written trade figure after handover, ask for the reason in writing. If nothing about the car was misdescribed and you can’t sort it out, contact your state or territory’s consumer affairs or fair trading agency. Our guide on why a car offer drops after inspection covers which reasons hold up.
The best protection starts on appraisal day. Get the trade figure, the odometer reading and any known damage written into the contract. Photograph the car and its odometer then and again at handover. Tell the dealer about finance owing and past repairs up front.
Why are trade-in rules of thumb on forums unreliable?
Car forums are full of rules of thumb: a trade offer should sit a set percentage below retail, or a dealer “needs” a fixed dollar margin on every trade. They’re opinions, not market data, and four things make them a poor guide to your car.
- People quote the trade figure, not the changeover. A “great trade” on a forum may have been paid for with a smaller discount on the new car.
- Every post is one car, one dealer and one month. Used prices move week to week.
- Dealer appetite changes. A dealer short of your model may pay more than one with three on the lot.
- Condition and history vary. Two cars with the same badge can be priced well apart once someone checks the logbook, keys and panels.
The only reliable benchmark is a set of real offers for your car, made in the same week.
Do you charge GST on a trade-in if you have an ABN?
Having an ABN doesn’t settle it on its own. What matters is whether you’re registered for GST and how the car was used. If the car is privately owned, the answer is no. The ATO says GST is not payable on the disposal of privately owned assets. That includes a sole trader’s car that wasn’t used in the business and on which no GST credit was claimed.
If you’re registered for GST and the car was used solely or partly in your business, it’s different. The ATO explains that trading the vehicle in is generally a taxable sale. GST is generally one-eleventh of the price, and you report it at G1 and 1A on your BAS. The dealer may ask you for a tax invoice showing the trade-in value and the GST.
That matters when you compare quotes, so ask whether the trade figure includes GST. In a made-up example, if a $33,000 trade figure includes GST, $3,000 of it is GST you account for to the ATO. The same rule applies if you sell the car outright, so GST doesn’t tip the decision either way. Luxury car tax can also apply when a GST-registered seller sells a luxury car.
These are general rules, not advice for your situation, so check with your accountant. Our guide on whether you pay tax when you sell your car goes into more detail.
Should you sell separately instead?
Sell separately when an outright offer beats your real trade figure by more than the extra effort is worth to you. Trade in when the numbers are close and one contract and one handover matter more. Timing is the usual worry, because selling first could leave you without a car. Our page on selling your car instead of trading it in covers how to line the sale up with your delivery date, including finance on the old car. For every option side by side, private sale included, see the best way to sell a second-hand car.
Two numbers, then decide
You don’t need to guess whether your trade-in value is low. Work out your real trade figure from the no-trade price and the changeover, then put it next to an outright offer from the same week. The bigger number wins, once you’ve allowed for your time.
If your car is 2021 or newer with 100,000 km or less, we can give you that second number. Sell Your Car Australia is run by Autohaus Australia Pty Ltd, a NSW licensed motor dealer (MD 077404). The business is run by a valuer who has priced cars since 1992 and supplies dealerships nationwide. The offer is a genuine one, made by phone, not an online estimate.
If you accept, we can often pay a deposit the same day. We inspect the car at a time and place that suits you and pay the balance into your bank account. We collect the car only after you confirm the funds have cleared. If you’d like to keep driving it until your new car arrives, tell us your delivery date on the call and we’ll confirm what timing works. If there’s finance owing, we deal with your lender directly to pay out the loan, then pay you any equity. Settlement usually takes 2 to 3 business days. As one seller, Rahul A, put it: “No haggling, or dealerships trying to get a lower price.”
The valuation is free, with no obligation and no fees taken out of the offer. Start with a free valuation or call 1800 73 55 73. If your car is older or has more kilometres, send it through anyway and we’ll tell you straight away if we can help.
Questions sellers ask
Is it better to trade in or sell my car?
It depends on the gap between your real trade figure and what buyers will pay for the car on its own. Work out the real trade figure from the dealer's no-trade price and changeover, then compare it with outright offers made in the same week. A private sale may return more again, but it takes time and you carry the payment and scam risk.
Can I sell my car after I've ordered a new one?
Yes. If the new-car contract doesn't include a trade-in, you can sell your car whenever you like. If it already lists your car as a trade-in, talk to the dealer first, because the trade is part of the deal you signed, and get any change to a no-trade price in writing. When you sell to us, the car is collected only after you confirm the funds have cleared, so tell us your delivery date on the call and we'll confirm what timing works.
Will a dealer give a fair trade-in on a used car I'm buying?
The same maths applies. Ask for the used car's drive-away price with no trade-in and the changeover with your trade, and the difference is what the dealer is really paying for your car. A used car has no current list price to check against, so without both numbers it's even harder to see how the deal has been split.
What happens if I owe more on the car than the trade-in figure?
The shortfall doesn't disappear when you trade in. The lender still has to be paid in full, so the difference is added to what you pay for the new car. If you sell to us instead, we deal with your lender directly to pay out the loan, and any negative equity has to be covered before settlement.
