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.
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.
