Car insurance is a contract between the owner of the car and an insurance company that serves to safeguard your vehicle from several unforeseen risks such as loss due to theft, accidents, or natural disasters.

Insured Declared Value (IDV) in Car Insurance

 

For any new or used car to be legal in India, it needs to be covered under a valid car insurance policy. Apart from that, the mere fact of knowing that your car is insured against any unforeseen event will give you peace of mind. While purchasing or renewing a car insurance policy, you pay a certain amount as a premium to the insurance company. There are various factors that decide the premium amount of your car insurance policy, and IDV or Insured Declared Value is one of the most significant factors.

  

What is IDV in car insurance? Why is IDV important ?

  

Insured Declared Value (IDV) is the sum insured of the vehicle at the beginning of the policy. It is the maximum amount that policyholders will get when they make a claim on a car insurance policy. Simply, it is the current market value of your car. If your car is stolen or gets severely damaged to an extent where it is beyond repair, the car insurance claim amount payable to you by your insurer is then calculated based on IDV. Hence, it is crucial to insure your car with the right IDV.

The IDV can be calculated with the following formula:

IDV (Insured Declared Value) = Ex-showroom price – Depreciation %

Key factors that influence your car insurance IDV

The IDV of a car is usually calculated based on the following key factors:

• Type of car:

Cars come in various types, from hatchbacks to sedans and SUVs etc. Therefore, the IDV calculated for each type differs from the other. Generally, SUVs attract higher value than sedans, and sedans have a higher value than hatchbacks.

• Make and model:

The make and model can be a deciding factor for calculating IDV since higher-end cars have higher IDV than lower-end cars due to the difference in repair and maintenance costs.

• Depreciation:

Depreciation is a decrease in the car's value due to wear and tear. As soon as you take the car out of the dealership, it starts depreciating. Hence, an older car has a lower IDV than a new car.

Other factors that may affect the calculation of an IDV can be -Place of registration, Accessories, Age of the car etc.

Why is calculating the right IDV important?

 

There is a direct correlation between the IDV of your car and your car insurance premium. The higher the value of IDV, the more the premium will be. For old cars, the IDV is usually lower, therefore the low amount of the premium.

However, it is crucial that you calculate the right amount for IDV, as opting for a lower IDV just to reduce your cost of the premium is not advisable, as it may prove to be non-beneficial and result in a loss if your car is stolen or meets with an accident and is totally damaged, the insurance company will only pay you the amount of IDV decided at the beginning and as per other policy conditions.

Hence, it is highly recommended to calculate the IDV of your car properly while buying or renewing your car insurance policy. Choosing the IDV that is near the market value of your car is advisable.

How to calculate IDV for car insurance?

The Insured Declared Value (IDV) represents your car’s current market value and forms the basis for your insurance coverage. Calculating IDV is simpler than it sounds, as it primarily depends on your car’s ex-showroom price and its depreciation over time.

Step 1: Understand Depreciation

As per IRDAI guidelines, insurers follow a fixed depreciation schedule based on the vehicle’s age:

Vehicle Age

Depreciation %

Less than 6 months

5%

6 months – 1 year

15%

1 – 2 years

20%

2 – 3 years

30%

3 – 4 years

40%

4 – 5 years

50%

More than 5 years

Depreciation is mutually decided by insurer and insured, usually 50% or more, depending on the car’s condition

Step 2: Apply the Formula

The basic formula for calculating IDV is:

IDV = Ex-Showroom Price – Depreciation

Step 3: Include Accessories (if any)

If your car has non-factory accessories, their depreciated value is added separately:

IDV = (Ex-Showroom Price – Depreciation) + (Cost of Accessories – 50% Depreciation)

Note: Factory-fitted accessories are already included in the ex-showroom price.

Choosing the right IDV ensures your premium is fair while providing adequate coverage in the event of theft, damage, or total loss. Regularly updating your IDV can help avoid under-insurance or overpaying on premiums.

How to calculate the cost of vehicle depreciation?

Depreciation is the reduction in your vehicle’s value over time and plays a key role in calculating its IDV. The rate of depreciation is standardised under the Motor Tariff Act as follows:

Age of Vehicle

Depreciation %

6 months and below

5%

6 months – 1 year

15%

1 – 2 years

20%

2 – 3 years

30%

3 – 4 years

40%

4 – 5 years

50%

 

Relation between a car’s IDV and its insurance policy premium

The Insured Declared Value (IDV) directly impacts your car insurance premium. A higher IDV means the insurer’s maximum payout in the event of theft or total loss is higher, which increases the premium. Conversely, a lower IDV reduces the premium but also lowers the claim amount. Choosing the right IDV ensures a balance between affordable premiums and sufficient coverage, protecting your vehicle without overpaying for insurance.

Conclusion

The Insured Declared Value (IDV) serves as the cornerstone of your car insurance policy, representing your car’s real-time worth. Selecting the correct IDV ensures you’re neither underinsured nor overpaying for coverage. When buying or renewing your car insurance with Zurich Kotak, always choose an IDV close to your car’s market value for fair, comprehensive protection against total loss or theft.
