Introduction
Every year, as a car gets older, the same question becomes more pressing at renewal: is the Own Damage component of the comprehensive policy still worth paying for, or has the time come to move to Third-Party-only cover? There is no single answer. The decision depends on your car's IDV, premium, age, usage and the financial risk you are willing to take.
This blog explains how insurance changes as your car ages, how IDV works after 5 years, how to compare the cost of comprehensive and Third-Party cover, and when each option may make sense. It also looks at how No Claim Bonus (NCB) factors into the decision.
Keep in mind
Car age is not the only factor to consider. Compare the cost of cover with your car's value and financial risk.
IDV reduces as the car ages and is mutually agreed with the insurer after 5 years.
Third-Party cover is mandatory. Switching to Third-Party only does not mean driving uninsured.
You lose Own Damage cover for theft, fire, floods and accident damage to your car.
Your No Claim Bonus can make comprehensive cover more affordable.
What changes as a car gets older, the insurance logic
A car insurance policy has 2 premium components that behave differently as the car ages.
The Third-Party (TP) premium is fixed by the Insurance Regulatory and Development Authority of India (IRDAI) based on the engine capacity of the car. For a car up to 1,000cc, such as a Maruti Alto or a Renault Kwid, the annual Third-Party rate is ₹2,094. This rate does not change based on the car's age. Whether the car is 3 years old or 13 years old, the Third-Party premium for the same engine class is the same.
The Own Damage (OD) premium is calculated on the car's IDV, which falls each year in line with the IRDAI depreciation schedule. As the IDV falls, the OD premium falls with it. A 10-year-old car has a significantly lower OD premium than the same model at 2 years old, but it also has a significantly lower IDV, which means the maximum payout in a theft or total-loss claim is also significantly lower.
As the car gets older, the OD premium usually becomes cheaper, but the car’s value also falls. At some point, the premium may no longer feel worth paying compared with the amount you could receive if the car is damaged or stolen. That point is different for every car, every owner, and every usage situation.
The Goods and Services Tax (GST) at 18% applies to the total premium on both plan types.
How the IDV works for older cars
The IDV is the current market value of the car, the maximum the insurer pays in a theft or total loss claim. For cars up to 5 years old, the IDV follows a fixed IRDAI depreciation schedule:
For cars over 5 years old, there is no fixed IRDAI schedule. The IDV is agreed by mutual consent between the insurer and the car owner. This is where the renewal review becomes most important, and where the most variation exists between insurers.
The insurer’s default IDV may not match your car’s actual market value. For example, a well-maintained 9-year-old car with low mileage and no accident history may be worth more than the same model with high mileage or past repairs. If you think the default IDV is too low, you can discuss and negotiate it with the insurer.
Before deciding whether to keep comprehensive cover on an older car, find out what the insurer's proposed IDV is. Research what the car would actually sell for in the used market today. If the insurer's IDV is close to the actual market value and the OD premium is proportionate, the comprehensive cover is providing real value. If the IDV has drifted below the actual market value, you are paying for cover that would pay out less than the car is worth.
Situations where comprehensive still makes sense for an older car
Age of the car alone is not a sufficient reason to move to Third-Party only. These are the situations where comprehensive cover continues to make financial or practical sense even on a car over 8 years old.
High-risk parking or location
A car parked on a public street in a city with a high vehicle theft rate is exposed to a risk that Third-Party cover does not address at all. If theft is a realistic risk for your specific car in your specific location, the IDV, even a low one, is better protection than none.
Regular highway or long-distance use
Accident risk increases on highways and unfamiliar routes compared to predictable urban commuting. A car used primarily for long-distance travel faces a different risk profile than one used for short local trips. Comprehensive cover on a highway car protects against damage that is more likely to occur.
Flood-prone routes or parking
Natural calamity cover, floods, cyclones, and lightning, is included in comprehensive cover and excluded entirely from Third-Party only. A car regularly parked in a basement during monsoon season in a flood-affected city faces a real risk that Third-Party only does not address.
The owner cannot absorb a large repair bill
If an unexpected repair bill of ₹40,000 to ₹80,000 would cause financial difficulty, the Own Damage cover, even at a lower IDV, provides protection worth having. The decision depends not just on the IDV and premium, but also on whether you can afford to pay for unexpected repairs or replace the car yourself.
An older car with high actual market value
Some older cars may be worth more in the used-car market than the standard depreciation-based IDV suggests. This can apply to well-maintained, low-mileage cars or models with strong resale value. In such cases, negotiating the IDV with your insurer becomes important, and comprehensive cover may still be worth keeping.
Situations where moving to Third-Party only makes sense
Moving to Third-Party only on an older car can make financial sense in these situations.
The IDV is low and the OD premium is a large part of it
If the insurer would pay ₹1.2 lakh for a total loss but you are paying ₹8,000 or more a year for OD cover, the premium may not offer enough value. If two or three years of premiums could cover a likely repair, paying for repairs yourself may be more cost-effective.
The car is used only for short local trips
If you mainly drive short, familiar routes and park in a private garage or gated compound, your risk of a major accident may be lower. In this case, the value of OD cover may also be lower.
You have a trusted mechanic and can pay for repairs
If you can get minor repairs done at a reasonable cost and afford moderate repair bills yourself, you may not need to pay for OD cover. This can be worth considering if you have built up a good NCB and want to avoid losing it through a claim.
The car is nearing the end of its life
If you plan to replace the car within the next one or two years, the cost of OD cover may not be worth it for the remaining period. The decision depends on whether the cover still provides enough value until you replace the car.
Moving to Third-Party only does not mean going uninsured. Third-Party cover remains in place, and the compulsory ₹15 lakh personal accident cover for the owner-driver is still required.
What you give up when you move to Third-Party only
Before making the switch to Third-Party only, it is worth being explicit about what is no longer covered. The events mentioned below are covered under comprehensive cover and not covered under Third-Party only:
Theft
If the car is stolen, the insurer pays nothing under Third-Party only. The full replacement or recovery cost falls with you
Accident damage to your own car
If you are in a collision and the car is damaged, Third-Party only pays nothing toward repairing your car, even if the accident was not your fault and the other driver cannot be identified or is uninsured
Fire
Damage from fire, whether from an electrical fault, a fuel leak, or an external source, is excluded under Third-Party only
Flood and natural calamities
Flood damage, cyclone damage, and earthquake damage to the car are excluded under Third-Party only
Man-made events
Vandalism, riot damage, and damage during a civil disturbance are excluded
The decision to move to Third-Party only is not simply a premium saving. It is an acceptance of the full financial risk for each of the events above. If any of these risks are likely for your car, consider the potential cost before dropping OD cover.
How the NCB connects to this decision
The No Claim Bonus (NCB) reduces your Own Damage premium for every claim-free year. This means the longer you go without making a claim, the less you pay for comprehensive cover.
For an older car, where the IDV and OD premium are already lower, a good NCB can make keeping comprehensive cover more affordable than the headline premium suggests. So, compare the OD premium after the NCB discount with the cover you would receive before deciding to switch to Third-Party only.
If a recent claim has reset your NCB, your OD premium will be higher at renewal. This may make Third-Party only more attractive, but consider whether your NCB will rebuild or whether you are likely to make more claims.
Moving to Third-Party only does not cancel your NCB. It remains valid for 3 years and can be used again if you buy comprehensive cover for the same or a new car within that period.
What this means: Your decision should be based on the actual OD premium you pay after NCB, not just the standard premium quoted by the insurer.
What Kiwi Insurance does differently
On an older car, the OD premium is already lower than it was when the car was new. A higher NCB discount can reduce that premium further, making comprehensive cover more affordable to keep.
Super NCB can go up to 90%
While a standard NCB is capped at 50%, Kiwi Super NCB can provide up to a 90% discount on the OD premium. This can significantly reduce the cost of comprehensive cover for a car that is already older.
One claim does not reset the NCB to zero
With Kiwi Super NCB, your discount drops by one level after a claim instead of going back to zero. This helps retain some of the benefit built up through previous claim-free years.
The higher discount can change the calculation
A lower OD premium after applying Super NCB can make comprehensive cover more affordable compared with moving to Third-Party only. The actual benefit depends on your car, IDV and premium at renewal.

Conclusion
The decision to keep comprehensive cover or move to Third-Party only on an older car is a financial calculation, not an age-based rule. The IDV, the OD premium net of NCB, the compulsory deductible, the depreciation deductions on older parts, and the owner's ability to absorb an unexpected repair bill all contribute to the comparison. Comprehensive cover continues to make sense on older cars that face real theft, flood, or accident risk, or where the owner cannot absorb a large repair bill.
With Kiwi Insurance, Super NCB makes the comprehensive plan more affordable on older cars by delivering a larger discount that steps down rather than resets after a claim.

Frequently asked questions
It depends on the car’s IDV, the OD premium after the NCB discount, and whether you can afford unexpected repair or replacement costs yourself. Comprehensive cover may still be useful if the car is at higher risk of theft, flooding or accidents, or if a large repair bill would be difficult to manage.
