─────  CAR INSURANCE  •  INDIA  •  2026 EDITION  ─────

Every year, thousands of Indian car owners discover — usually at the worst possible moment — that their insurer will not pay what they expected after an accident or theft. The reason is rarely fine print or fraud. It is a single number, fixed quietly at the time of buying or renewing the policy, that most people never look at twice: the Insured Declared Value, or IDV.

Get it wrong, and you could be short by lakhs of rupees exactly when you need the money most. Get it right, and you pay a fair premium while staying fully protected. This guide breaks down everything an Indian car owner needs to know about IDV — in plain language, backed by IRDAI's official rules.

01  What Exactly Is IDV?

The Insured Declared Value is the maximum sum your insurer agrees to pay if your car is stolen or declared a total loss (damaged beyond economical repair). Think of it as the "sum insured" for your vehicle under a comprehensive or standalone own-damage motor policy.

In simple terms:  IDV = Current manufacturer's ex-showroom price of your car − Depreciation (based on the car's age), as per the schedule fixed by the Insurance Regulatory and Development Authority of India (IRDAI).

It does not apply to third-party liability cover, which is priced separately by IRDAI based on engine capacity, regardless of your car's value. IDV governs only the own-damage portion of your policy — repairs, theft, and total-loss payouts.

02  Why IDV Is the Single Most Important Number in Your Policy

✓  It decides your maximum payout — if your car is stolen and never recovered, or written off after an accident, IDV is the ceiling, not the price you paid or what a dealer would offer today.

✓  It moves your premium directly — a higher IDV means a higher own-damage premium; a lower IDV lowers your premium but also your protection.

✓  It anchors your loan settlement — lenders typically insist on an IDV high enough to cover the outstanding loan amount.

✓  It affects add-on eligibility — covers such as Return-to-Invoice are calculated with reference to IDV.

03  How IRDAI Calculates IDV

THE OFFICIAL DEPRECIATION TABLE

IDV is not something insurers can set arbitrarily. Under the India Motor Tariff framework that IRDAI continues to enforce, every insurer must apply the same standardised, age-based depreciation schedule to the vehicle's current ex-showroom price (base model, before accessories):

For cars older than five years, or for discontinued models, there is no fixed slab — the IDV is negotiated directly between the insurer and the policyholder, usually referencing the current used-car market value.

04  A Worked Example

Here is how the numbers actually play out for a mid-size hatchback in a real accident scenario:

The takeaway:  with the correct IDV, the owner recovers close to the car's true depreciated value. With an artificially low IDV — say, ₹3,50,000 instead of ₹4,80,000 — the same accident would leave the owner short by well over a lakh of rupees.

05  The 75% Rule: When Your Car Becomes a “Total Loss”

IRDAI's motor insurance rules specify that a vehicle is treated as a Constructive Total Loss (CTL) when the aggregate cost of repair and retrieval exceeds 75% of its IDV. Once that threshold is crossed, insurers do not pay for individual repairs — instead, they settle the claim at the full IDV (minus the value of the wreck, i.e., salvage), and the registration certificate for that vehicle must be cancelled.

06  Common Mistakes Indian Car Owners Make

✕  Accepting the lowest auto-suggested IDV to shave a few hundred rupees off the premium, without realising it shrinks the claim ceiling by tens of thousands.

✕  Forgetting to declare CNG/LPG kits, branded alloy wheels, or other aftermarket accessories, leaving them uninsured at the time of a claim.

✕  Not renegotiating IDV for a well-maintained older car (5+ years), where insurers may default to an unfairly low figure unless the owner pushes back with evidence of the car's condition.

✕  Ignoring the lender's minimum IDV requirement on a financed vehicle, which can create a mismatch between the loan payoff amount and the claim payout.

✕  Confusing IDV with resale value — IDV is a claims ceiling fixed by a regulatory formula, not what a buyer would actually pay for the car today.

07  How to Choose the Right IDV

1. Start from the insurer's IRDAI-calculated default figure — it is usually a fair, defensible baseline for the current policy year.

2. Cross-check it using more than one insurer's online IDV calculator; the base ex-showroom price and depreciation slab should match across providers for the same car and age.

3. Declare and separately insure any non-factory accessories or fitments you have added.

4. If your car is well-maintained with low mileage and you plan to keep it for a few more years, avoid pushing the IDV artificially low just to save on premium.

5. If you are close to selling or scrapping the car, a marginally lower IDV within the permissible range can be a reasonable way to trim the premium.

6. For financed vehicles, confirm the IDV meets or exceeds your lender's minimum requirement before finalising the policy.

08  IDV vs No Claim Bonus (NCB)

DON'T CONFUSE THE TWO

IDV and NCB are frequently mixed up, but they do very different jobs. IDV decides how much you can claim; NCB decides how much discount you earn on the own-damage premium for staying claim-free. IRDAI mandates a uniform NCB slab structure across all insurers, applied only to the own-damage premium:

Filing even one claim resets NCB to zero, while IDV is recalculated every year regardless of your claims history. A high NCB and a poorly chosen IDV can coexist — a cheap premium is not the same thing as adequate cover.

09  Frequently Asked Questions

A.  Not entirely. Insurers are permitted some flexibility around the IRDAI-calculated figure, but they will generally decline an IDV that is unrealistically low or high relative to the standard schedule, since both increase the insurer's risk of moral hazard or under-recovery.

A.  The own-damage premium moves roughly in proportion to IDV, but the increase is usually modest compared to the extra protection gained — particularly for newer or well-maintained cars.

A.  There is no fixed depreciation slab beyond five years. The IDV is mutually agreed between you and the insurer, so it is worth negotiating using comparable used-car listings or valuation reports as evidence.

A.  No. Third-party-only policies carry a fixed premium set by IRDAI based on engine capacity, independent of the car's value. IDV only applies to the own-damage component of comprehensive or standalone own-damage covers.

A.  IDV is fixed at the start of each policy period and generally cannot be revised mid-term. You can review and adjust it only at the next renewal.

10  The Bottom Line

IDV rarely gets a second glance at renewal time, buried between the premium amount and the payment button. But it is the number that decides what happens on the worst day you could have with your car — a theft, a fire, an accident too severe to repair. Spend five extra minutes checking it every year, declare your accessories, and negotiate it fairly if your car is ageing well. That small effort is what turns a car insurance policy from a compliance formality into real financial protection.
