What is Depreciation, and Why Does it Matter in Car Insurance?
Car depreciation is the reduction in the value of a car and its parts due to wear and tear from the time of purchase to when it is sold. This depreciation directly impacts the Insured Declared Value (IDV) of the car as well as its insurance premium.
Car insurance companies calculate the IDV by subtracting the vehicle depreciation rate from the manufacturer's selling price at the time of purchase. In the event of an accident involving the insured vehicle, the IDV determines the maximum compensation a car owner can receive from the car insurance company.
How Do Insurers Calculate Car Depreciation Rates?
Insurers consider these factors to determine the car depreciation rate and insurance premium:
- Age of the Car: The physical condition and mileage of a car are calculated based on its age. The older the car, the lesser its value.
- Fuel Efficiency: Fuel-efficient cars are cost-effective and have a good resale value.
- Model of the Car: Large luxury cars have a higher depreciation rate than smaller cars because their parts/maintenance are usually more costly.
- Maintenance: The more maintained a car is, the lower its depreciation will be. If your vehicle has bodywork issues or a poor interior, you can expect a high depreciation rate.
- Number of Owners: When it comes to calculating the car depreciation rate, the rule is that the fewer the owners, the better its value.

How to Minimise Car Depreciation Rate?
Here are a few simple tips to minimise depreciation on your car and get a higher IDV and resale value:
- Maintenance of Your Car: Keeping your car in good shape increases your chances of receiving a better resale value. Ensure that you maintain a record of the timely servicing. Also, try avoiding modifications in your car, as selling it becomes more difficult.
- Buy a High-Resale Car Model: Some cars hold their value better than others. Do deep research on the resale values of various four-wheelers before you buy one. By this, you can avoid a car with a higher depreciation rate.
- Buy Zero Depreciation Cover: Buy the zero depreciation add-on cover under your car insurance policy, as it repays you for the claim amount that gets deducted due to vehicle depreciation.
