IDV is applicable to policies that provide coverage for damage to the insured vehicle, such as comprehensive car insurance and standalone own-damage policies.
However, it does not apply to third-party insurance because such policies only cover liabilities arising from injury, death, or property damage caused to another person. Since third-party insurance does not cover damage to the insured vehicle, there is no requirement to determine an IDV.
For vehicles covered under comprehensive insurance, the IDV forms an important part of the policy and is usually specified in the policy schedule.
The IDV is generally calculated by considering the manufacturer's listed selling price of the vehicle and then applying depreciation based on the vehicle's age.
In simple terms:
IDV = Manufacturer's Listed Selling Price – Depreciation
The calculation excludes registration charges, road tax, and insurance costs.
For vehicles fitted with accessories not included by the manufacturer, the value of those accessories may also be considered separately while determining the final insured value.
Age of Vehicle | Depreciation Applied |
Up to 6 months | 5% |
6 months to 1 year | 15% |
1 year to 2 years | 20% |
2 years to 3 years | 30% |
3 years to 4 years | 40% |
4 years to 5 years | 50% |
Note: For vehicles older than five years, the IDV is generally determined through mutual agreement between the insurer and policyholder, based on the vehicle's condition and market value.
IDV is not a fixed figure throughout a vehicle's lifetime.
As a car ages, its market value gradually declines due to depreciation, wear and tear, and changing market demand. As a result, the IDV generally decreases at every policy renewal.
Two cars of the same make and model may also have different IDVs depending on factors such as age, condition, modifications, and insurer assessment.
Various factors influence the IDV assigned to a vehicle. These include:
Older vehicles attract higher depreciation. This may result in a lower IDV.
Premium vehicles generally have a higher IDV compared to economy models.
A well-maintained vehicle may command a better market valuation than one with visible wear and damage.
Additional accessories not included by the manufacturer may influence the overall insured value if declared.
Demand and resale value in the used-car market can also impact the assessment of a vehicle's value.
The IDV value is more than just a number mentioned in the policy document.
It directly affects:
A well-chosen IDV value helps strike a balance between adequate protection and a reasonable premium.
Some vehicle owners assume that selecting the highest possible IDV in car insurance will automatically result in a larger claim pay-out. However, this is not always the case.
Insurance claims are settled according to policy terms and the actual value of the vehicle. Choosing an unrealistically high IDV can increase the premium without necessarily providing proportionately higher benefits.
Similarly, opting for a significantly lower IDV may reduce the premium but could leave the vehicle underinsured.
For this reason, selecting an IDV that reasonably reflects the vehicle's market value is generally advisable.
The concept of IDV applies to two-wheelers as well.
Just like a car insurance plan, the IDV in a bike insurance policy represents the estimated market value of the vehicle after depreciation. It is used to determine compensation in cases of theft or total loss.
The calculation principles remain largely the same, although the vehicle value and depreciation amounts may differ.
There is no single IDV value for car insurance that suits every vehicle.
When reviewing the IDV offered at renewal, consider:
The ideal IDV is usually one that closely reflects the vehicle's realistic market value rather than being excessively high or low.
Many insurers also provide an IDV calculator for car insurance, allowing policyholders to estimate an appropriate value before renewal.
Neither option is ideal if it does not reflect the vehicle's actual worth.
A very high IDV in car insurance may increase costs, while a very low IDV may lead to inadequate coverage in the event of a major loss. The goal should be to choose an IDV that reasonably aligns with the vehicle's current market value.
Use an IDV calculator to understand valuation estimates before renewal.
The Insured Declared Value is one of the most important elements of a car insurance policy. It influences claim settlements, determines the extent of financial protection available, and affects the premium payable for own-damage coverage. Understanding how IDV works can help vehicle owners choose appropriate coverage and make more informed decisions at the time of policy purchase or renewal.
A suitable motor insurance policy from SBI General Insurance can help vehicle owners stay financially protected while ensuring their coverage reflects the value of their vehicle.
IDV, or Insured Declared Value, is the estimated current market value of a vehicle after depreciation. It serves as the maximum sum insured for theft or total loss claims under own-damage coverage.
IDV is calculated by applying depreciation to the manufacturer's listed selling price of the vehicle, excluding registration charges, road tax, and insurance costs.
Yes. A higher IDV in car insurance generally results in a higher own-damage premium, while a lower IDV may reduce the premium.
Insurers may allow some flexibility in selecting the IDV within prescribed limits. However, the chosen value should reasonably reflect the vehicle's market value and insurer guidelines.
