It is obvious that a car doesn’t hold its showroom value for long. The moment you drive it off the lot, its price starts to drop, a process known as car depreciation. This drop isn’t random; it depends on a few key things like how old the car is, how many kilometres it’s been driven, its overall condition and even how popular that model is in the market.
Depreciation also ties directly to motor insurance through the Insured Declared Value (IDV), the maximum amount your insurer will pay if your car is stolen or completely damaged. So whether you’re planning to sell your car, renew your car insurance policy, or simply calculate your ownership costs, understanding depreciation can help you make smarter financial choices.
Read on to see how these factors influence your car’s value and insurance premium.
7 Factors Influencing Car Depreciation
The following are the major factors that influence car depreciation:
1. Age of the Vehicle
Age is one of the biggest factors affecting car depreciation. As a vehicle gets older, its market value steadily declines. Cars that are more than 10 years old usually have the lowest resale value, as wear and tear, outdated technology and reduced efficiency make them less desirable to buyers. The only exceptions are classic, collectible or specialty models, which can sometimes appreciate in value due to their rarity or growing demand among enthusiasts.
2. Mileage and Odometer Reading
Mileage also plays a major role in car depreciation. In general, the higher the mileage, the lower the car’s value. A vehicle that has been driven extensively is likely to show more wear on its engine, tyres and interiors, which brings down its resale price. On the other hand, cars that are driven less and well-maintained tend to retain their value longer, as they usually have less mechanical stress and appear in better condition overall.
3. Physical Wear and Tear
A car’s condition greatly affects its resale value. Worn tyres or brakes, scratches, dents and faded paint can quickly bring down its worth. In contrast, well-maintained cars serviced regularly at authorised centres and backed by proper service records depreciate more slowly. Vehicles with accident history or frequent repairs tend to lose value faster due to concerns about reliability.
4. Brand Value and Market Trends
Brand reputation and demand play a big role in how much value a car retains. Models from trusted manufacturers with reliable after-sales support and affordable maintenance usually depreciate slower. Market preference also matters. SUVs, for instance, often have higher resale value. Policy changes, like new emission rules or fuel regulations, can also influence how quickly a car loses its worth.
5. Number of Owners
Multi-owner vehicles usually lose their value faster, since continuous changes in ownership make it challenging to determine the maintenance history. Well-documented single-owner vehicles are usually more desirable in the second-hand market.
6. Fuel Type and Efficiency
Fuel type also affects how a car holds its value. Petrol cars generally retain their resale value better than diesel vehicles, which face stricter emission norms and higher registration costs in many states. Cars that are more fuel-efficient usually depreciate slower, as they remain cheaper to run. As electric and hybrid vehicles become more common, factors like government incentives and the availability of charging infrastructure will play a big role in how their value changes over time.
7. Insurance and Depreciation Link
Depreciation has a direct effect on motor insurance, particularly affecting the Insured Declared Value (IDV), which determines the highest claim payable in the event of theft or complete loss. Vehicles that depreciate more have lower IDV, which influences insurance premiums and settlement claims.
Similarly, if you do not file any claims during the policy year, you can benefit from a No Claim Bonus, which can you your car insurance premiums. NCB in car insurance is a reward you get for safe driving for not making any claims during your policy period.
How to Calculate Car Depreciation According to IRDAI?
The standard rates of depreciation for the purpose of arriving at the Insured Declared Value (IDV) of a vehicle, as per Insurance Regulatory and Development Authority of India (IRDAI), are as follows:
| Age of Vehicle | Depreciation Rate |
| Less than 6 months | 5% |
| 6 months to 1 year | 15% |
| 1 year to 2 years | 20% |
| 2 years to 3 years | 30% |
| 3 years to 4 years | 40% |
| 4 years to 5 years | 50% |
| More than 5 years | Determined mutually between insurer and insured |
Conclusion
Car depreciation is shaped by a combination of factors, such as age, mileage, wear and tear, brand reputation, ownership history, fuel type and changing economic or regulatory conditions. Together with IDV calculations in car insurance, these determine how much value a vehicle retains over its lifetime. Understanding these factors helps you make smarter financial decisions, whether selling your vehicle or renewing a car insurance policy.
