When you take out comprehensive car insurance in Australia, you’re usually asked to pick how your car is valued for a total-loss claim: agreed value or market value. It’s an easy box to tick without thinking — but it decides exactly how much you’d be paid if your car were written off or stolen, and it affects your premium too. Get it wrong and you could be underinsured, or paying for cover you don’t need.
Here’s a clear, side-by-side look at agreed value vs market value so you can choose the option that matches your car and how you use it.
The quick answer
Agreed value means you and the insurer lock in a set figure upfront — if the car is written off, that’s roughly what you’re paid (less any excess). Market value means the insurer pays what the car is worth at the time of the claim, based on its make, model, age, condition and kilometres. Agreed value gives you certainty; market value usually costs less in premium but leaves the payout to be calculated later.
How agreed value works
With agreed value cover, you nominate (or the insurer proposes) a fixed sum insured when you take out or renew the policy. That figure is “agreed” between you and the insurer, and it’s the amount used to settle a total-loss claim, minus your excess and subject to the policy terms. Some insurers offer a range and let you pick within it.
The upside: certainty. You know exactly what you’re covered for, which protects you against depreciation during the policy year and is reassuring for newer cars, financed cars, modified cars or anything you’d struggle to replace at a generic “market” figure.
The trade-off: premiums are often higher, and you usually need to review the agreed figure each renewal so it stays sensible as the car ages.
How market value works
With market value cover, you don’t set a figure. If the car is written off, the insurer assesses what it was worth at the time of the claim — using its age, condition, kilometres and comparable sales — and pays that, less your excess.
The upside: market value policies often come with a lower premium, and for an older car that’s depreciating steadily, the payout may be perfectly adequate. You’re not paying to insure a figure higher than the car is realistically worth.
The trade-off: uncertainty. The amount is decided after the loss, not before, so it can be lower than you expected — especially if the market has softened — and there’s more potential for disagreement about what the car was worth.
Agreed value vs market value — side by side
| Feature | Agreed value | Market value |
|---|---|---|
| Payout amount | Set figure agreed upfront | Assessed at the time of claim |
| Certainty | High — you know the number | Lower — calculated after the loss |
| Premium | Usually higher | Usually lower |
| Protects against depreciation in the year | Yes | No |
| Need to review each renewal | Yes (keep the figure realistic) | Not really |
| Often suits | Newer, financed, modified or higher-value cars | Older, lower-value or high-depreciation cars |
Cover terms, definitions and how each value is calculated vary between insurers — always read the Product Disclosure Statement (PDS) for the specific policy.
Which should you choose?
It comes down to the car and how much certainty you want:
Agreed value tends to suit newer cars, cars under finance (where you want the payout to cover what you owe), modified or prestige vehicles, and anyone who simply wants to know the exact figure they’re covered for. If a total loss would leave you scrambling to replace the car, the certainty can be worth the higher premium.
Market value tends to suit older, lower-value cars that depreciate predictably, owners watching their premium, and situations where the likely payout is close enough to the car’s worth that paying extra for a locked-in figure doesn’t add much.
A practical tip when you’re buying a car: factor the insurance choice into your running costs before you sign, not after. If you’re financing the car, agreed value can help make sure a write-off payout lines up with the loan balance. Our guide to buying a car covers the wider cost picture, and it’s worth understanding the difference between comprehensive and third-party cover first, then choosing how your car is valued within a comprehensive policy.
Whatever you choose, read the PDS and check how that insurer defines and calculates the value — the labels are standard, but the fine print isn’t.
Frequently asked questions
What is the difference between agreed value and market value car insurance?
Agreed value means you and the insurer set a fixed payout figure when you take out the policy, so you know exactly what you’re covered for. Market value means the insurer decides the payout at the time of a claim based on the car’s age, condition and comparable sales. Agreed value offers certainty; market value is usually cheaper.
Is agreed value or market value better for car insurance?
Neither is universally better — it depends on your car. Agreed value suits newer, financed, modified or higher-value cars where certainty matters. Market value can suit older, lower-value cars and owners wanting a lower premium. Consider the car’s value, whether it’s under finance, and how much certainty you want before choosing.
What does agreed value mean on car insurance?
Agreed value is a set amount you and your insurer agree on when you start or renew the policy. If your car is written off or stolen, that figure is used to settle the claim, minus your excess and subject to the policy terms. It protects you from depreciation during the policy period.
What does market value mean in car insurance?
Market value is what your car is worth at the time of a claim, not a figure set in advance. The insurer assesses the car’s make, model, age, condition and kilometres against comparable sales to decide the payout, less your excess. It can be lower than expected if values have fallen.
Does agreed value cost more than market value?
Usually, yes. Agreed value policies often have higher premiums because you’re locking in a guaranteed figure that’s protected from depreciation during the year. Market value policies are typically cheaper because the payout is assessed at claim time. Compare quotes for both on your specific car to see the real difference.
Should I insure a financed car for agreed or market value?
Many owners of financed cars choose agreed value so the payout in a write-off is more likely to cover what they still owe. With market value, depreciation could leave the payout short of the loan balance. Check the figures against your loan and read the policy, as terms vary between insurers.
How do insurers calculate market value?
Insurers estimate market value using your car’s make, model, year, condition and kilometres, compared against recent sales of similar vehicles and valuation guides. Because it’s assessed at the time of the claim, the figure reflects current conditions, which can be higher or lower than when you bought the policy. Definitions vary, so check the PDS.
