Old Car? Third-Party vs Comprehensive Insurance — Exactly When to Switch (2026)

·

As a car ages its value falls but comprehensive premium doesn't drop as fast. Here's the simple math for when own-damage cover stops being worth it.

Old Car? Third-Party vs Comprehensive Insurance — Exactly When to Switch (2026)
The verdict: Keep comprehensive while the car is under ~8–10 years and still worth something; consider third-party-only once it's 10+ years, IDV is under ~₹1 lakh, and you could absorb a repair yourself. Never drop third-party — it's the legal minimum.

For a new car, comprehensive is a no-brainer. For a 12-year-old car worth little, it can look like throwing good money after bad. Here's the line, with numbers.

Why the math shifts as the car ages

Comprehensive premium is tied to your car's IDV, which falls every year — but the own-damage payout is capped at that shrinking IDV, minus depreciation and deductibles. So each year you pay premium for a smaller possible payout.

A worked example

13-yr-old hatchbackFigure
IDV (max own-damage payout)~₹80,000 (and falling)
Comprehensive premium~₹6,500/yr
Third-party only~₹2,500/yr
Extra you pay for own-damage~₹4,000/yr to protect a shrinking ₹80k

A simple decision rule

  • Keep comprehensive if: under ~8–10 yrs, meaningful value, you couldn't absorb a big repair, or high-risk driving.
  • Third-party only if: 10+ yrs, IDV under ~₹1 lakh, secondary/occasional car, and you have savings to self-insure.

Middle path: third-party plus one cheap high-value add-on (roadside assistance) instead of full comprehensive — get quotes both ways.

FAQ

Legal to keep only third-party? Yes — it's the legal minimum; own-damage is optional.
