  • IDV and car insurance premium: Now, let us understand the bearing IDV has on your car insurance premium. It actually has a direct impact on the premium. This is because the premium of your plan depends on the size of the cover. When the IDV is high, your car has a high valuation and is covered with a high car insurance cover. The premium of the high cover is also high. Similarly, when the IDV is low and your car is cover is lower too, the premium is less too. Therefore, the IDV does have a very strong impact on the premium of your car insurance policy.
  • IDV and car insurance claims: The IDV also affects the car insurance claims. This is because if your vehicle is stolen or it is completely damaged, your insurance provider will pay you compensation according to the IDV. So here too, the insured declared value plays a very crucial role.
