IDV explained: how your car’s insured value is set (and why it matters)
Insured Declared Value is the maximum a motor claim can pay and the base your premium is built on. Set it wrong and you lose either way.
Key takeaways
- IDV is the cap on a total-loss or theft payout, and the base for your premium.
- Under-declaring IDV to cut premium means a smaller payout when the car is written off.
- Over-declaring does not increase your payout — insurers pay the car’s actual value.
When you insure a car, one number quietly governs both what you pay and what you can ever get back: the Insured Declared Value (IDV). Most buyers skim past it. That is a mistake.
What IDV actually is
IDV is the insurer's assessment of your vehicle's current market value — roughly the showroom price less depreciation for its age. It is two things at once:
- The maximum claim the insurer will pay if the car is stolen or a total loss (written off beyond economical repair).
- The base on which your own-damage premium is calculated.
Because it drives both, IDV is where a lot of buyers unknowingly trade away protection for a slightly lower premium.
The under-declaring trap
Some buyers (or agents chasing a cheaper quote) set a low IDV to shrink the premium. It works — the premium drops — but the day the car is stolen or written off, the payout is capped at that low IDV. You saved a little each year and lost a lot once.
Over-declaring doesn't help either
Setting IDV higher than the car is worth does not get you a bigger payout — at total loss the insurer settles at the vehicle's assessed value, not an inflated IDV. You would simply have paid a higher premium for nothing.
The right approach
Set IDV close to the honest current market value of your car. That keeps your premium fair and your total-loss payout adequate. When you renew, IDV naturally falls as the car ages — that is correct, and it is why an older car costs less to insure on the own-damage part.
Illustrative example (not a quote): two identical cars, one insured at a realistic ₹6 lakh IDV and one under-declared at ₹4 lakh. Both are stolen. The first owner is made whole; the second is short ₹2 lakh — far more than the small premium they saved.
Where a broker helps
At renewal, insurers often propose an IDV at the low end of the allowable band (it makes their quote look cheaper). A Trustner broker checks the IDV is realistic for your car, compares own-damage and third-party components across insurers, and makes sure a cheaper quote isn't cheaper only because your future payout was quietly cut.
