How do companies calculate car insurance premium

Sunday, 7 July 2013

Ever wondered how your car insurance premium is calculated? Often the premium can be adjusted for any bonus or discount that the insurer is willing to offer you, but in any case these are calculated only after the insurer has fixed a premium that they want to charge you. Here we explain the factors that influence the premium that you pay for your car.
Insured declared value
At any given point, your car has some value associated with it. If you suffer a total loss in an accident, how much do you think you should be compensated for, assuming you had insurance for your car? The amount that you are compensated for under a comprehensive motor insurance coverage is directly linked to what is the value of the vehicle at that point in time.
If you have a new car that you have just driven out of a showroom, its value is more than say a three-year-old car with 30,000 km on it. Insured declared value, or IDV, is the value that the insurance company places on your vehicle to estimate its worth at the time you apply for motor insurance.
Motor insurance policies are indemnity policies. That's just a technical way of saying that they just compensate you for an amount up to financial loss that you have suffered on the vehicle, and no more.
IDV is the maximum amount that you can claim under a motor insurance policy to compensate for any loss arising from theft or accident. So, if you suffer total loss in an accident of your three-year-old car that is worth Rs 4 lakh at the time of the accident, under no circumstances will you be compensated for more than Rs 4 lakh.
When you buy a new car and are getting insurance for it, the IDV is calculated on the basis of the price of the new car, i.e., its ex-showroom price. If you have a car for which you are renewing the insurance, the IDV will be adjusted for any operational wear and tear that the car has experienced, or to put it in technical terms the IDV is adjusted for any depreciation that it has undergone for a vehicle of its age.
What if you have any accessories like a special music system or speakers in your car? In this case, the value of these items that are additional to the price of the car are added to the IDV, adjusted for any depreciation that these items might have undergone. If you are getting a policy for a car that is more than 5 years old, then the IDV is determined on the basis of an understanding between you and the insurer after adjusting for the depreciation schedule.
Please keep in mind that the IDV calculation is used only for a comprehensive insurance policy and not a third party insurance cover.
Cubic capacity of the vehicle
Every car has an engine size, which is measured as its cubic capacity. The size of the engine affects the insurance premium you have to pay for a third party insurance cover.
The premium amount is the same for a new car as for an older car, because the premium is a function of the engine size, and not the age of the car. Engine capacity is not a criterion used for calculating premium for a comprehensive cover.
The table below shows the rates (as of June 2010) on the third party cover premium amount according the engine size. The higher the cc, the higher will be the premium. You can find out the cc from the registration papers of your vehicle. (See Cover Drive: Table 1).
These figures are the basic minimum amounts as stipulated by the Indian Motor Tariff Act. There might be an additional amount that you are obliged to pay above this minimum for third party coverage. These minimum amounts are the same, irrespective of the brand or the age of the car. All that matters is the engine capacity.
