What Is IDV in Car Insurance? Total-Loss Payout Rules 2026

Quick answer: IDV (Insured Declared Value) is the sum insured on the own-damage part of your motor policy — the most your insurer will pay if the vehicle is stolen or written off. It is not what you paid for the car, and it is not the resale price. It is the manufacturer's listed selling price of your exact variant, minus a fixed depreciation percentage set by the vehicle's age.

IDV is the one number on your policy nobody checks

Open your motor policy schedule. Near the top there is a line marked "IDV" or "Insured's Declared Value". Most people skim past it on the way to the premium. That figure is the ceiling on every own-damage payout you will ever receive under that policy — and unlike the premium, you cannot renegotiate it after a crash.

Two things follow. First, IDV only exists on policies that cover your own vehicle: a comprehensive package or a standalone own-damage cover. A third-party-only policy carries no IDV, because it does not pay for your vehicle at all — our explainer on comprehensive versus third-party cover sorts out which you hold. Second, IDV is re-fixed at the start of every policy period and falls each year as the vehicle ages. This year's number is not last year's.

How insurers arrive at your IDV

The method comes from General Regulation 8 of the India Motor Tariff. Own-damage pricing was de-tariffed in 2007 and insurers now set their own rates, but the product structure — policy wordings, IDV, depreciation — still runs on the tariff's General Regulations. That is why the same grid turns up in policy wordings filed with IRDAI right across the market.

Start with the manufacturer's listed selling price for your exact make, model and variant. Then subtract depreciation by age:

• Not exceeding 6 months — 5%
• 6 months to 1 year — 15%
• 1 to 2 years — 20%
• 2 to 3 years — 30%
• 3 to 4 years — 40%
• 4 to 5 years — 50%

Past five years the grid simply stops. The tariff provides that IDV for vehicles over five years old, and for obsolete models, is settled by mutual agreement between insurer and insured — which in practice means the insurer proposes a figure and you either accept it or push back. Accessories fitted to the vehicle that are not part of the listed price are valued separately and depreciated on the same basis.

Note what the base excludes: registration charges, road tax and the insurance cost itself. That is why a one-year-old car's IDV already sits well below what you spent getting it on the road. Nothing has gone wrong — the formula was never measuring your out-of-pocket cost.

The General Insurance Council maintains a standardised IDV calculator for private cars, built so that the same make, model, variant, age and state produce a consistent IDV across insurers, with values refreshed monthly. If a quoted IDV looks odd, that is a sensible place to sanity-check it.

When IDV actually decides your money

For an ordinary dent-and-repair claim, IDV barely matters — the insurer pays the assessed repair cost. IDV becomes the whole ballgame in three situations.

Theft

There is nothing left to repair. You are paid the IDV, less the deductible on your schedule, once the police file an untraced-vehicle report.

Total loss

The vehicle is destroyed or rendered permanently incapable of use. Again, IDV is the payout.

Constructive total loss

This is the one that catches people out. The vehicle can be repaired — it is simply not worth repairing. The market standard under the tariff framework is that once the aggregate cost of repair and retrieval crosses 75% of IDV, the insurer declares a constructive total loss and pays the IDV rather than funding the repair. Individual wordings can express the threshold differently, so read yours instead of assuming 75% applies everywhere.

Constructive total loss shows up most often after serious water ingress, which makes this worth reading alongside what a motor policy does and does not do for flood damage to a car.

The expensive mistake: shaving IDV to cut the premium

Own-damage premium is charged as a percentage of IDV, so a lower IDV genuinely does produce a lower premium. A deflated IDV is an easy way to make a quote look sharp. Do the arithmetic once and you will never fall for it.

Take a car with a listed price of Rs 10,00,000, now three and a half years old. At 40% depreciation, the IDV works out to Rs 6,00,000. Accept a quote pitched at Rs 4,50,000 instead and you have cut your maximum theft or write-off payout by Rs 1,50,000. Because the own-damage rate applied to IDV is a small percentage, the premium you saved is a fraction of the cover you surrendered — a certain small gain traded against a rare large loss, which is the exact opposite of what insurance is for. (Figures are illustrative; your rate and variant price will differ.)

The reverse has limits too. You cannot inflate IDV to manufacture a bigger payout: insurers typically permit only a modest band of variation around the computed value, and a motor claim remains a contract of indemnity.

IDV depreciation is not parts depreciation

This is the most common mix-up. The age grid above fixes your IDV, and IDV governs total-loss and constructive-total-loss claims. A separate schedule — General Regulation 9 — governs partial claims, where damaged parts are replaced. There, depreciation is charged on the parts themselves:

• Rubber and nylon or plastic parts, tyres, tubes, batteries and airbags — 50%
• Fibreglass components — 30%
• Parts made of glass — nil
• All other parts, including wooden parts, by vehicle age — nil up to 6 months, 5% to 1 year, 10% to 2 years, 15% to 3 years, 25% to 4 years, 35% to 5 years, 40% from 5 to 10 years, and 50% beyond 10 years

That parts schedule is exactly what a zero-depreciation add-on buys out. Zero-dep does nothing whatsoever for your IDV — it only stops the insurer applying these percentages to a repair bill. Two different problems, two different fixes, and a frequent reason people feel short-changed on a claim they believed was fully covered.

If the vehicle is written off, one step people forget

A total-loss settlement is not the end of the paperwork. Under Section 55 of the Motor Vehicles Act, 1988, where a vehicle has been destroyed or rendered permanently incapable of use, the owner must report the fact to the registering authority within fourteen days and forward the registration certificate for cancellation. Insurers commonly ask for proof of this before releasing the settlement.

Expect two other adjustments. If you keep the wreck, its salvage value is deducted from what you receive; if the insurer takes the wreck, you are paid the IDV less the deductible. And a write-off is still a claim, so the no-claim bonus you had built up resets when you insure the next vehicle.

Renewal checklist

• Read the IDV on the schedule before you read the premium.
• Check it against your vehicle's age band in the grid above, or the GI Council calculator.
• Confirm that accessories, CNG or LPG kits and aftermarket fittings are separately declared and valued.
• If the vehicle is over five years old, ask how the offered IDV was arrived at — that is the negotiable zone.
• Never accept a lower IDV purely to hit a premium target.
• Find the constructive-total-loss threshold in your own policy wording.
• Note the compulsory deductible printed on your schedule; it comes off every own-damage claim, including a write-off.

Frequently asked questions

Is IDV the same as my car's market value?

No. Market value is what a buyer would actually pay, reflecting condition, kilometres, service history and local demand. IDV is a formula applied to the variant's listed price. The two can differ substantially in either direction, especially for models with strong resale demand.

Can I ask for a higher IDV at renewal?

You can ask, and insurers usually allow some variation around the computed figure. How much varies by insurer and is at their discretion, so treat it as a conversation rather than a right. It matters most for older vehicles, where the figure is set by agreement anyway.

Does IDV apply to two-wheelers as well?

Yes. The same General Regulation 8 basis applies to bikes and scooters on own-damage cover. The GI Council's standardised calculator currently covers private cars, so for two-wheelers you will be working from the depreciation grid and your insurer's quote.

Why did my IDV fall so sharply in the second year?

Because the grid steps rather than sliding smoothly. A vehicle just under six months old carries 5% depreciation; cross one year and it is 15%; cross two and it is 20%. Renewing a few weeks either side of a birthday can land you in a different band.

After a flood, do I get repair costs or IDV?

It depends on the assessed repair cost against the constructive-total-loss threshold in your wording. Below it, the insurer funds the repair with parts depreciation applied. Above it, the claim is settled at IDV. Cover for water damage itself requires own-damage cover, and engine damage from water ingress often needs an engine-protection add-on.

Does a zero-depreciation add-on raise my IDV?

No. Zero-dep waives depreciation on replaced parts in a repair claim. Your IDV, and therefore your theft and write-off payout, is unchanged.
