Car insurance premium calculation is done primarily on the basis of Insured Declared Value (IDV) of the specific model. The IDV is calculated on the ex-showroom price of the car and it changes annually as per the depreciation rate of a certain model. The other factors affecting car insurance premium include no claim bonus which is rewarded to the insured for not making any claims during the policy term. No Claim Bonus(NCB) can be accumulated to a staggering 50% on the premium amount. Discount on car insurance can be availed if the car owner has installed an anti-theft device approved by ARAI (Automobile Research Association of India) or opts for a voluntary deductible.
Yes, the policy can be cancelled and the unused premium amount refunded usually on a pro-rata basis. This will happen only if an alternate insurance proof is offered, and claims aren’t raised subject to 30 days prior to the policy expiry date. If a claim is raised, refund shall not be made. There could also be a nominal cancellation, which is charged.
For the purpose of applying premium rate, the place where the vehicle is registered is taken into consideration, instead of the place where the vehicle is used. If your vehicle has been registered in Mumbai, the rate applicable for Zone A is charged. Even when you shift to a different city, the same premium rate will be applicable for your vehicle. Similarly, if a vehicle is registered in a town or a tier 2 city, it attracts Zone B premium rate. Subsequently even if the owner shifts to a metro, he will continue to be charged the Zone B rate.

If at all your premium decreases it could be because your IDV has reduced. Or perhaps, you had a claim-free year so you can ask for NCB discount. Or perhaps you chose to discontinue certain add-on covers. For example, you may have had a zero-depreciation add-on but that would be valid only till the 5th year. From the 6th year onwards, since the add-on is discontinued, your premium is lowered by default.


If your car is not insured and involved in an accident, you might have to pay to rent a car or cover repairs yourself. Comprehensive and Collision coverage as part of your car insurance policy is a much better value because, even if you're not involved in an accident, you can still be protected against theft, fire, vandalism and windshield damage.
