Insured Declared Value (IDV)

Insured Declared Value (IDV) is the maximum Sum Assured fixed by the insurer which is provided on theft or total loss of vehicle. Basically, IDV is the current market value of the vehicle. If the vehicle suffers total loss, IDV is the compensation that the insurer will provide to the policyholder.

IDV is calculated as manufacturer’s listed selling price minus depreciation. The registration and insurance cost are excluded from IDV. The IDV of the accessories which are not factory fitted, are calculated separately at extra cost if insurance is required for them.

Depreciation Schedule to fix IDV of a Car

The following table shows the depreciation schedule used to fix the IDV of a car:

Age of Vehicle % Depreciation for adjusting IDV
Not exceeding 6 months 5%
Exceeding 6 months but not exceeding 1 year 15%
Exceeding 1 year but not exceeding 2 years 20%
Exceeding 2 years but not exceeding 3 years 30%
Exceeding 3 years but not exceeding 4 years 40%
Exceeding 4 years but not exceeding 5 years 50%

The IDV of vehicles aged over 5 years is calculated by mutual agreement between insurer and the insured. Instead of depreciation, IDV of old cars is arrived at by assessment of vehicle’s condition done by surveyors, car dealers etc.

IDV Calculator

The IDV Calculator is an online tool that determines the market value of your car as well as estimates the ideal premium amount that you should be paying for your car insurance. It takes into account the age of your vehicle or depreciation to arrive at the correct IDV for your car.

Insured Declared Value = (Company’s listed price – the depreciation value) + (Cost of vehicle accessories - the depreciation value of these parts)

The above-mentioned formula is to calculate the IDV for a new car that is equipped with extra accessories that were added after the purchase of the car. In case you do not have any such accessories in the vehicle, the IDV calculation is simple.  You can easily calculate Insured Declared value of your using the online IDV calculator. And the formula is enclosed below:

IDV = Manufacturer’s registered price – the value of depreciation

The depreciation applicable will be as per the table gave above.

For instance - If your car’s value or IDV is fixed at INR 5 lakh at the time of policy purchase, the insurer will recompense a maximum amount in the event of total loss or damage will be INR 5 lakh. It is imperative to you will get compensation only in case of constructive total loss or in case of theft of the car within the policy term.

Things to Keep in Mind While Calculating IDV for a Car

Make sure that you take into consideration the below-mentioned points to carefully assess the IDV of your car-

  • The value of your car is derived by deducting the depreciation value from the actual market price. In any case, it is the maximum compensation that you will get in case of total loss or theft of your car.
  • Correct valuation of IDV may cost you less premium
  • Just to reduce the premium do not reduce the IDV of your car, as this would mean less claim or a disputed claim
  • Right declaration of IDV would mean rightful claim
  • Do your research or check with the manufacturer before agreeing to the IDV set by your car insurance provider
  • Also, assess the premium cost and check if it has been correctly evaluated on the basis of your car’s IDV
  • It is important that you get adequate coverage and are satisfied with the Insured declared value as it involves a lot of money. You can also negotiate to get the desired IDV.
  • While renewing your car insurance plan, make sure that the cost of the premium is determined on the basis of the IDV. If your car’s market value as compared to the IDV is very high, this would mean exorbitant premium in comparison to a car that costs lower.

You can also fix your car’s IDV online, but this will vary from one insurer to another. It also gives you an opportunity to adjust your IDV while renewing your car, so make sure that you don’t miss a chance.

Factors that Help to Determine the IDV of a Car

The following factors help an IDV calculator to estimate the IDV of your car. Take a look:

  • Age of the Car – The age of your car is one of the biggest factors that help determine the IDV of your car. The higher the age of your car would be, the lower will be its IDV.
  • Make and Model of the Car – The make & model of the car helps to determine how high-end is the car and how high would be its repair cost. For example, the IDV of a BMW X7 would be higher than the IDV of a Hyundai Santro due to its higher cost and maintenance.
  • Standard Depreciation – The depreciation schedule shown in the table earlier impacts the IDV of your car. The depreciation to the market value of your car is charged based on the percentage mentioned in the depreciation schedule.
  • City of Car Registration – The city where your car has been registered also influence the IDV. The IDV of a car registered and running in a metropolitan city like New Delhi will be open to more risks than the IDV of a car running in a small town in UP.

How Does IDV Affects Car Insurance Premium?

The IDV of your car is directly proportional to your car insurance premium. This means the higher the value of IDV, more will be the amount of premium charged to you. Similarly, as the IDV of your car will reduce with its increasing age, the premium amount payable by you will also reduce.

However, it is not advisable to opt for a lower IDV just to reduce your premium amount because it will result in losses. A lower IDV means you will receive a lower compensation amount in case of total damage or theft claims. The whole idea is to get an IDV closest to the market value of your car without paying enormous amounts as premium.

Why is IDV important in Car Insurance?

As explained, IDV is the amount that you will get in case your vehicle is stolen or suffers total loss. It is highly recommended to get IDV which is near the cost of market value of car.

Why Should You Care About Your Car’s IDV?

The IDV of your car is an extremely crucial aspect of buying a car insurance policy. Besides determining the maximum compensation amount for your car, it also plays a vital when it comes to the premium of your car insurance policy.

The IDV is the key to the amount of premium that you will pay for your car insurance. This is because IDV reflects the current market value of your car and mirrors the liability of your motor insurance company at the time of claim settlement. Lower IDV means lower liability for the insurance provider and thus, a lower premium is charged and vice versa. However, there are other factors, such as the type of cover, geographic zone, add-on covers, etc that also help arrive at the final premium amount for your car insurance policy.

That’s not all. The IDV of your car also plays an important role when you decide to sell it. If the IDV of your car is high, it will automatically fetch you a higher selling price. Similarly, a lower IDV will lead to selling your car for a lower price. Although there are other factors, such as claims experience, that also affect the selling price of your car, you should be extremely careful when fixing the IDV for your car.

Insured Declared Value FAQs

  • Q1: What will be the IDV for a new car?

    Ans:  Ideally, the insured declared value or IDV of a new car should be equivalent to the invoice value of the car. However, depreciation is deducted even from the value of a new car because it has been sold for usage. Generally, the depreciation charged on a new car is about 5% and thus, the default maximum IDV of a new car stands at 95% of the invoice value of the car.
  • Q2. How much is the IDV of a car outside the showroom?

    Ans:  The moment a new car leaves the showroom, depreciation is taken into account to estimate the IDV. Up to the first six months of buying a car, most motor insurers levy only 5% of depreciation on the invoice value of the car. Therefore, the IDV of a car outside the showroom will be the ex-showroom value of the car minus 5% depreciation i.e. 95% of the invoice price of the car.
  • Q3. Is it wise to go for a high IDV?

    Ans:  Whether you should go for a high IDV or a low IDV depends completely on the age and condition of your car. If your car is relatively new and is in a perfect condition, then going for a high IDV is ideal. However, if your car is older than five years and is not in a very good condition then it is better to avoid a high IDV and go for a low IDV.
  • Q4. How much can the IDV of a car vary?

    Ans:  IDV of car insurance is decided by taking into account the depreciation value of the car. However, motor insurance companies allow car owners to increase or decrease the set IDV by 15%. So if the IDV of your car is Rs 5 lakh as per the depreciation, you have the freedom to choose an IDV between Rs 4,25,000 and Rs 5,75,000.
  • Q5. Which IDV is the best for cars?

    Ans:  The best IDV for cars or any other vehicle is the one which is the closest to the current market value of the car.
  • Q6. Why does IDV vary from one insurance company to another?

    Ans:  The IDV of your car may vary from one insurance company to another because insurers reduce the IDV to attract the customers by offering lower insurance premium. Lower IDV also reduces their liability, thereby, allowing them to pay lower compensation during claim settlements.
  • Q7. Why does the IDV of a car reduce every year?

    Ans:  The IDV of a car reduces every year because the market value of the car reduces every year. This happens due to the depreciation in the car’s value with age and usage.
