When you buy or renew car insurance, you may see the term IDV mentioned alongside the premium. But what exactly does IDV mean, and why does it matter?
IDV stands for Insured Declared Value. It is an important concept in motor insurance, particularly when considering claims involving situations such as theft or a total loss, subject to the terms of the policy.
This guide explains IDV in car insurance in simple language, including what it means, how it is determined, why it affects premiums, and what you should check when comparing policies.

What Is IDV in Car Insurance?
IDV means Insured Declared Value.
In simple terms, IDV represents the insured value of the vehicle for applicable purposes under a motor insurance policy.
It is particularly relevant when a vehicle is considered a total loss or constructive total loss, or when the vehicle is stolen, subject to the applicable policy terms and conditions.
IDV should not simply be considered the same as the price you would receive if you sold your used car privately.
Why Is IDV Important?
IDV can be an important factor when comparing car insurance policies because it is connected with the insured value of the vehicle.
For example, suppose two insurance options have similar premiums but different IDVs. Looking only at the premium would not give you the complete picture.
You should also examine:
- IDV
- Coverage
- Deductibles
- Exclusions
- Add-ons
- Claim conditions
- Policy terms
This is why comparing car insurance purely on price can be misleading.
How Is IDV Determined?
The method used to determine IDV depends on the applicable motor insurance framework and insurer's policy terms.
Generally, the vehicle's value is considered after accounting for depreciation according to the applicable methodology.
Factors can include:
- Vehicle's age
- Manufacturer and model
- Original listed value
- Applicable depreciation
- Accessories, where relevant
- Policy terms
The exact calculation can vary, so always check the IDV shown in the actual insurance quotation or policy document.
Is IDV the Same as the Market Value of Your Car?
No.
This is an important distinction.
IDV is not necessarily the same as the current second-hand market price of your vehicle.
The price at which you might sell a used car can depend on factors such as:
- Vehicle condition
- Mileage
- Location
- Service history
- Demand for the model
- Number of previous owners
- Local market conditions
IDV is determined according to the applicable insurance methodology and policy terms.
How Does IDV Affect Car Insurance Premium?
IDV can have an effect on the premium for certain motor insurance covers.
Generally, a higher insured value can result in a higher premium for the relevant own-damage cover, while a lower insured value can result in a lower premium.
However, premium is influenced by several factors, not IDV alone.
Other factors can include:
- Vehicle details
- Location
- Type of coverage
- Add-ons
- Deductibles
- Claim history
- Applicable discounts
- Insurer pricing
Therefore, don't choose a policy solely because it has the lowest premium.
What Happens If You Choose a Very Low IDV?
A lower IDV may make the applicable premium lower in some circumstances.
However, there can be an important trade-off.
If the vehicle is subsequently subject to an eligible total-loss or theft claim, the applicable settlement can be affected by the insured value and the policy terms.
Therefore, choosing an artificially low IDV simply to reduce the premium may not be appropriate.
What Happens If You Choose a Higher IDV?
A higher IDV may increase the applicable premium.
However, a higher IDV can also mean a higher insured value for applicable claims, subject to the policy's terms and conditions.
The objective should not simply be to select the highest possible IDV.
Instead, compare the IDV offered by the insurer with the applicable methodology and your vehicle's circumstances.
IDV and Total Loss
IDV becomes particularly important when a vehicle is treated as a total loss or constructive total loss under the applicable policy.
For example, if a vehicle is severely damaged in an accident and meets the policy's definition of a total or constructive total loss, the claim settlement will be determined according to the policy terms.
IDV can be relevant to that settlement.
The exact calculation may also consider deductibles and other applicable conditions.
IDV and Car Theft
IDV can also be relevant when an insured vehicle is stolen.
If the claim is accepted and the policy provides the applicable theft coverage, the settlement is handled according to the policy conditions.
The policyholder should therefore check the IDV when buying or renewing comprehensive or own-damage motor insurance.
Does IDV Matter in Third-Party Insurance?
IDV is primarily relevant to the insured vehicle's own-damage coverage rather than third-party liability protection.
A third-party-only policy generally does not provide own-damage protection for your vehicle.

IDV and Comprehensive Car Insurance
IDV is particularly relevant when comparing comprehensive or other policies that provide own-damage protection.
A comprehensive policy generally combines third-party liability protection with specified protection for the insured vehicle.
However, comprehensive insurance does not mean every possible loss is covered.
Exclusions, deductibles, limits and other conditions continue to apply.

Simple IDV Example
Imagine that you have an older car and are comparing two insurance quotations.
Policy A
- Lower premium
- Lower IDV
- Similar basic coverage
Policy B
- Slightly higher premium
- Higher IDV
- Similar basic coverage
The cheaper option is not automatically the better comparison simply because the premium is lower.
You should examine why the IDVs differ and check the policy terms, deductibles, exclusions and other features.
The actual suitability depends on the individual vehicle and policy.
What Should You Check Before Accepting the IDV?
Before purchasing or renewing car insurance, check:
1. Vehicle Details
Make sure the vehicle's make, model, variant and registration details are correct.
2. IDV
Check the IDV shown in the quotation and policy document.
3. Premium
Compare the premium after considering the coverage and applicable add-ons.
4. Deductible
Check both compulsory and voluntary deductibles where applicable.
5. Add-ons
Understand exactly what additional protection each selected add-on provides.
6. Exclusions
Read the exclusions rather than assuming that comprehensive insurance covers every situation.
7. Claim Conditions
Understand the insurer's claim process and documentation requirements.
IDV vs Resale Value
These two terms are often confused.
| IDV | Resale Value |
|---|---|
| Used for applicable motor insurance purposes | Price a buyer may pay for the used vehicle |
| Determined according to applicable insurance methodology | Determined by the used-car market |
| Relevant to certain insurance claims | Relevant when selling the vehicle |
| Appears in applicable insurance documentation | Depends on buyer, seller and market conditions |
Your car's resale price and its insurance IDV therefore do not necessarily have to be identical.
Common Mistakes to Avoid
Choosing Insurance Only on Premium
A cheaper premium may come with a different IDV, deductible, coverage or set of exclusions.
Ignoring the IDV
Always check the IDV when reviewing an own-damage or comprehensive insurance quotation.
Assuming Higher IDV Is Always Better
Higher IDV can also mean a higher premium. Compare the overall policy rather than focusing on one number.
Assuming IDV Equals Market Price
IDV and second-hand market value are different concepts.
Not Reading the Policy Conditions
The actual claim settlement depends on the policy wording and applicable conditions.
