For a new car, comprehensive insurance is a no-brainer. For a 12-year-old car worth very little, paying comprehensive premium can start to look like throwing good money after bad. So where's the line? Here's how to decide with numbers instead of guesswork — while staying legal and safe.
First, the non-negotiable
Third-party insurance is mandatory, whatever your car's age. Dropping all insurance is illegal and financially reckless — third-party covers your liability if you injure someone or damage their property, which can run into lakhs. The only real question is whether to keep the own-damage (comprehensive) portion.
Why the math shifts as the car ages
Comprehensive premium is tied to your car's IDV (market value), which falls every year. But it doesn't fall to zero, and the own-damage payout is capped at that shrinking IDV — minus depreciation and deductibles. So each year you pay premium for a smaller and smaller potential payout. Past a point, the cover costs too much relative to what it can ever pay you.
A worked example
Example: a 13-year-old hatchback has an IDV of about ₹80,000. Comprehensive costs ~₹6,500/year; third-party alone is ~₹2,500. The most the own-damage part can ever pay on a total loss is ~₹80,000 (less depreciation). If the car is in good shape and you can absorb a repair or even a write-off, paying an extra ₹4,000/year to protect an ₹80,000 asset that keeps shrinking may not be worth it.
A simple decision rule
- Keep comprehensive if: the car is under ~8–10 years, still has meaningful value, you couldn't comfortably absorb a big repair, or you drive a lot in high-risk conditions.
- Consider third-party only if: the car is 10+ years old, IDV is low (say under ~₹1 lakh), the car is a secondary/occasional vehicle, and you have savings to self-insure repairs.
A smart middle path
You don't have to go all-or-nothing. Some drivers keep third-party plus one cheap, high-value add-on (like roadside assistance or basic own-damage) rather than full comprehensive with every rider. Get quotes both ways and compare — see our premium-reduction guide.
FAQ
Is it legal to keep only third-party? Yes — third-party is the legal minimum; own-damage is optional.
Will I lose my No Claim Bonus if I switch to third-party? NCB applies to own-damage; if you return to comprehensive later within the allowed window, you can often retain it — check with your insurer.
What if the old car gets stolen? Without comprehensive, theft isn't covered — factor that into the decision.
