Agreed Value vs Market Value Insurance

When you insure your car or other assets, you typically choose between agreed value and market value. This choice affects how much you receive if your vehicle is written off or a total loss is declared.

What is Agreed Value? What is Market Value? Side-by-Side Comparison Which is Better? NZ Insurer Options FAQs

What is Agreed Value Insurance?

With agreed value insurance, you and your insurer agree on a specific dollar amount for your vehicle (or asset) when you take out or renew the policy. If your vehicle is written off or stolen, you receive this agreed amount (minus your excess), regardless of what the vehicle might be worth on the open market at the time of the claim.

The agreed value is typically set based on the vehicle's market value at the time of policy inception, though you may be able to negotiate a higher value if you have modifications, low mileage, or the vehicle is in exceptional condition.

Agreed value provides certainty - you know exactly what you will receive in a total loss situation. This is particularly valued by owners of classic cars, modified vehicles, or vehicles that may be difficult to value using standard market guides.

Tip
Review your agreed value at each renewal. If you set it too high, you may be paying more in premiums than necessary. If it is too low, you may not receive enough to replace your vehicle.

What is Market Value Insurance?

With market value insurance, your vehicle is insured for whatever it is worth on the open market at the time of the claim - not when you took out the policy. This means the payout can go up or down depending on market conditions, depreciation, and the condition of your vehicle.

Insurers typically use industry valuation guides (such as the Red Book or Trade Me listings) to determine market value. They may also consider the vehicle's age, mileage, condition, and recent sale prices of similar vehicles.

Market value policies generally have lower premiums than agreed value policies because the insurer's maximum liability decreases as the vehicle depreciates. However, there is less certainty about what you will receive in a total loss.

Important
With market value cover, your payout reduces over time as your vehicle depreciates. A car you bought for $25,000 might only be valued at $18,000 two years later.

Side-by-Side Comparison

Here is how agreed value and market value compare across the key factors that matter when choosing your cover.

Agreed Value vs Market Value Comparison
Feature Agreed Value Market Value
Payout amount Fixed at policy inception Determined at time of claim
Certainty of payout High - you know the amount upfront Lower - depends on depreciation and market
Premium cost Generally higher Generally lower
Depreciation impact None - payout is locked in Payout decreases as vehicle depreciates
Best for newer vehicles Yes - protects against rapid depreciation Can work if premiums are a priority
Best for older vehicles Less common; may not be offered Often the default option
Classic/modified vehicles Strongly suited May undervalue modifications
Risk of over-insuring Possible if value set too high Not applicable - based on current value
Risk of under-insuring Possible if not reviewed at renewal Possible if market guides undervalue the vehicle

Which Valuation Method is Better?

Neither option is universally better - the right choice depends on your vehicle and priorities. Here are some common scenarios:

For new or near-new vehicles, agreed value is commonly chosen because new cars depreciate rapidly in the first few years. With market value, you could face a significant gap between what you paid and what your insurer pays out.

For older vehicles with lower values, market value is often the default and may be the only option offered. The premium savings of market value are more meaningful when the vehicle's value is lower.

For classic cars, modified vehicles, or imports, agreed value is often essential. Standard market value guides may not accurately reflect the true value of these vehicles. Classic car insurance specialists typically offer agreed value as standard.

For vehicles with finance owing, agreed value can be important. If you owe more on the vehicle than its market value (sometimes called being "upside down" on a loan), a market value payout may not cover your remaining loan balance.

Note
Some insurers offer a third option called "retail value" which bases the payout on what it would cost to buy a similar vehicle from a dealer. This sits between agreed value and market value.

What NZ Insurers Offer

Key Takeaways

  • Agreed value locks in a set payout amount; market value is based on the vehicle's worth at claim time
  • Agreed value provides more certainty but typically costs more in premiums
  • Market value premiums are usually lower but payouts decrease as your vehicle depreciates
  • Agreed value is commonly chosen for new, classic, modified, or financed vehicles
  • Market value is often the default for older vehicles with lower values
  • Review your agreed value at each renewal to ensure it reflects your vehicle's current worth

Frequently Asked Questions

Yes, most insurers allow you to switch at renewal. Some may allow mid-term changes. Contact your insurer to discuss your options and any premium adjustment.
The agreed value is typically based on industry valuation guides, your vehicle's age, mileage, and condition. You and your insurer must both agree on the amount. Some insurers may request a professional valuation for high-value or unusual vehicles.
If you believe your insurer's market valuation is too low, you can provide evidence such as recent sale listings for similar vehicles, a professional valuation, or dealer quotes. If you cannot reach agreement, the IFSO can assist with disputes.
This depends on your policy and whether the modifications were declared to your insurer. You should inform your insurer of any modifications and ensure the agreed value reflects the total value including modifications.
House insurance in NZ typically works differently. Most policies offer either a specified sum insured (similar to agreed value) or a replacement value. The concept is similar - ensuring your sum insured reflects the actual cost to rebuild your home.
