IDV in car insurance: the one number that decides your theft and total-loss payout

Picture this. Your car is stolen on a Tuesday. You file the claim expecting roughly what the car is worth — and the insurer pays you ₹1.5 lakh less. No loophole, no dispute, nothing to appeal. They're simply paying out a number you approved, without reading it, at your last renewal.

That number is your IDV — and most people rubber-stamp it while comparing premiums. Set it too low to shave a little off the premium, and you've quietly capped your own payout. Set it too high thinking you'll get more back, and you're paying every year for money you can never collect. Either way, the mistake surfaces at the worst possible moment: the day you file a claim.

Here's exactly what IDV is, how it's calculated, and how to check yours before you renew — in about two minutes.

What IDV actually is

IDV stands for Insured Declared Value. It is the maximum amount your insurer will pay if your car is stolen or damaged beyond economical repair — a "total loss." For your car, IDV is your sum insured. Under the India Motor Tariff (GR-8), the IDV "shall be deemed to be the sum insured" for the policy.

Two things it is not:

• It is not your car's resale or market price.
• It is not the ex-showroom price you paid.

IDV is the manufacturer's current listed price for your exact model, minus a fixed depreciation based on the car's age. That depreciation schedule is standardised — not left to each insurer's mood.

How IDV is calculated: the fixed depreciation grid

IDV = the current listed selling price of your model − standardised depreciation for its age. The schedule (India Motor Tariff) is:

Age of vehicle	Depreciation for fixing IDV
Up to 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%
Over 5 years / discontinued model	No fixed rate — agreed between you and the insurer

So a brand-new car insures at roughly 95% of its listed price; a four-to-five-year-old car at about 50%. Past five years there's no fixed grid — the value is negotiated. That last row matters: it's where insurers have the most room to quote you a low IDV, and where you have the most room to push back.

Why a wrong IDV costs you — in both directions

Too low: the trap that looks like a saving

Your own-damage premium is calculated as a percentage of IDV. So a lower IDV means a lower premium — which is exactly why an agent or a quote screen may nudge it down. On the renewal page, it looks like you saved money.

But IDV is the cap on your theft and total-loss payout. Under-state it, and if the car is stolen or totalled, you're paid the low IDV you agreed to — not what it costs to replace the car.

For example: say a fair IDV for your car is around ₹6,00,000, but it's been set at ₹4,50,000 to trim the premium. You might save a few thousand rupees a year. But if the car is stolen, you're paid ₹4,50,000 — a ₹1,50,000 gap that dwarfs whatever you saved on premium. (Illustrative figures — your own numbers depend on your model and insurer.)

Too high: paying for money you can't claim

Some buyers inflate IDV expecting a bigger payout. You'll pay a higher premium for it — but at claim time you can't extract more than the car's genuine value under the policy terms. You've overpaid every year for a number you can never actually collect.

The honest position: a slightly lower IDV for a lower premium is a valid choice — if you knowingly accept the smaller theft/total-loss payout. The problem is when it happens by default, without you realising what you traded away.

The "75% rule" most people miss

Your car doesn't have to be physically destroyed to count as a total loss. Under the tariff, it's treated as a Constructive Total Loss (CTL) when the cost of retrieval and repair crosses 75% of the IDV.

This is where a low IDV quietly cuts twice:

• A lower IDV makes CTL trigger more easily — 75% of a smaller number is a smaller repair bill.
• And once it's declared a total loss, your payout is that smaller IDV — and the policy ends.

So under-setting IDV doesn't just shrink the cheque; it makes the write-off come sooner.

Don't confuse IDV with depreciation on repairs

There are two different depreciation rules in motor insurance, and people mix them up constantly:

• IDV depreciation (the grid above) applies to total loss and theft — the whole-car cap.
• A separate depreciation applies to individual parts in a normal repair claim — for example, 50% on rubber, plastic, tyres, tubes and batteries, and nil on glass (India Motor Tariff).

That second one — parts depreciation on repairs — is what a zero-depreciation add-on waives. IDV is a different lever entirely. Fixing one does nothing for the other.

How to check your own IDV before you renew

A two-minute check before you click pay:

1. Find the IDV on your policy schedule. It's stated explicitly — usually near the premium breakup.
2. Sanity-check it against the grid. Take the current listed price of your exact model, subtract the age-based depreciation above, and see whether your IDV sits roughly in that band — or suspiciously below it.
3. For a 5+ year car, get two or three quotes. There's no fixed grid past five years, so insurers vary widely. Don't accept the first low IDV offered.
4. Decide on purpose. If you want a lower premium and accept a smaller theft payout, fine — choose it knowingly, not by accident.
5. Confirm the premium was actually calculated on the IDV shown. A mismatch is worth questioning.

FAQ

What is IDV in simple terms? It's the most your insurer will pay if your car is stolen or written off. For your car, IDV is the sum insured.

Is a higher or lower IDV better? Neither by default. A lower IDV means a lower premium but a smaller theft/total-loss payout; a higher IDV means a higher premium but you still can't claim more than the car is genuinely worth. It's a trade-off you should make deliberately.

Can I choose my own IDV? Insurers typically let you set IDV within a small range around the computed value. Beyond five years, where there's no fixed depreciation grid, it's negotiated between you and the insurer.

Does IDV affect my premium? Yes. Own-damage premium is calculated as a percentage of IDV, so a lower IDV lowers your premium — and lowers your payout at total loss.

What happens to IDV after five years? There's no fixed depreciation rate. The value is agreed between you and the insurer, so it pays to compare a few quotes rather than accept the first.
