FAQs on What is IDV?

1. In the case of a new car, what will be the IDV?

If possible, the invoice value of a new car should equal the insured declared value or IDV. A new car is still depreciated even when it is a brand new car because it has been sold for usage. As a rule of thumb, depreciation is about 5% on new vehicles, so a new car's default maximum invoice value is 95% of its invoice value.

2. What is the invoice price of an outside-the-showroom car?

To estimate the IDV, depreciation is taken into account when a new car leaves the showroom. Most motor insurers charge only 5% of depreciation on the car's invoice value in the first six months after purchase. Therefore, the IDV of a vehicle outside the showroom is the invoice price minus 5% depreciation, therefore 95% of the ex-showroom value.

3.Do you think it's wise to go for a high IDV?

You should choose a high IDV if your car is old and in good condition or a low IDV if it is in poor condition. When you have a new car in good shape, you should go for a high IDV. However, if your vehicle is more than five years old and not in excellent condition, you should find a low IDV and avoid one with a high IDV.

4. To what extent can a car's IDV vary?

The IDV of car insurance is determined by factoring in the vehicle’s depreciation value. Nevertheless, motor insurance companies allow their customers to increase or decrease their set IDV by 15%. As a result, if your IDV as calculated by depreciation is Rs 5 lakh, you can choose between Rs 4,25,000 and Rs 5,75,000.

5. Which is the best IDV for cars?

Depending on the type of vehicle, IDV is best when it is the closest to the vehicle’s current market value.

6. IDVs differ among insurers for a variety of reasons. What are they?

Your car's IDV may differ from one insurance company to another since insurers lower the IDV to attract customers by lowering insurance premiums. A lower IDV also reduces their liability, compensating claimants at lower levels.

7. What causes the IDV of a car to decrease every year?

The IDV of a car decreases every year due to the depreciation of the car's market value. Cars depreciate as they get older and are used more frequently.

8. How are declared values calculated in the case of car insurance?

Depreciation on automobile parts is deducted from the Insured Declared Value. Registration and insurance on the vehicle are not included in the IDV. Accessories fitted to the car are calculated separately if they are not factory-fitted.

9. What is the best IDV for me?

As soon as you purchase a car, you are given the IDV based on the manufacturer's listed selling price. In normal circumstances, the depreciation of a new car is five percent, so the maximum IDV should be ninety-five percent of the vehicle's ex-showroom price.

10. What causes the IDV to decrease every year?

According to the Insurance Declared Value (IDV), your car is insured up to the maximum value for which it is covered in the event of total loss/theft for any given year. In normal circumstances, the value of a car depreciates over time. Because of this, the IDV of your vehicle is not just determined by its depreciated value but also by its market value.
