This article explains what IDV (Insured Declared Value) means in motor insurance, how it is calculated using IRDAI’s depreciation schedule and why choosing the right IDV affects both your annual premium and your claim payout. Covers cars and two-wheelers. Takes about 5 minutes to read.
IDV – Insured Declared Value – is the number that decides everything when a claim goes bad. Car stolen? Written off after a crash? Whatever your insurer pays you is capped at the IDV. Full stop. It’s not the price you originally paid for the vehicle. It’s what the insurer says the car is worth right now, after depreciation is factored in. Get the IDV right and you’re covered properly. Let it drift too low – or deliberately set it low to save on premium – and you’ll feel that gap at the worst possible moment.
Two things. That’s what IDV controls: how much you get paid if the worst happens, and how much you pay every year for that cover. Higher IDV means a bigger payout if the car’s stolen or written off – and a slightly higher annual cost. Lower IDV trims the premium. But it also trims the cheque you receive when you need to claim.
Say your IDV is ₹5,00,000 and your car gets stolen. You walk away with ₹5,00,000, minus any deductibles. Fine. But what if the car was genuinely worth ₹6,50,000 in the market at that point? That ₹1,50,000 shortfall is yours to absorb. No claim process will recover it. That’s underinsurance – and it’s far more common than most policyholders expect, because shaving the IDV to cut premium feels clever right up until you actually need to make a claim.
WATCH OUT
Setting a very low IDV to save on premium looks smart on paper. In practice, the insurer pays only up to the IDV in a total loss or theft claim – not what the car is actually worth. Never set IDV significantly below the vehicle’s real market value.
QUICK STAT
As of 2025, third-party-only policies account for roughly 66% of all motor insurance policies in India – meaning only about 1 in 3 insured vehicles carries comprehensive own-damage cover with IDV protection.

The formula isn’t complicated. IRDAI sets it via the Indian Motor Tariff:
DID YOU KNOW?
IRDAI’s India Motor Tariff (GR-8) defines IDV as the vehicle’s ‘Sum Insured’ – fixed at the start of each policy period based on the manufacturer’s listed selling price adjusted for age-based depreciation. This is the regulator’s own definition, not a product feature that insurers can modify.

IDV = Manufacturer’s Listed Ex-Showroom Price − Depreciation
The depreciation rates are fixed by regulation – they don’t shift based on how well the car has been maintained or how low the mileage is. Age is the only variable:
| Vehicle Age | Depreciation Rate | IDV as % of Ex-Showroom Price |
|---|---|---|
| Under 6 months | 5% | 95% |
| 6 months to 1 year | 15% | 85% |
| 1 to 2 years | 20% | 80% |
| 2 to 3 years | 30% | 70% |
| 3 to 4 years | 40% | 60% |
| 4 to 5 years | 50% | 50% |
Once a car crosses 5 years, this table stops applying. At that point, IDV becomes a negotiation – you and the insurer settle on a figure based on the car’s condition, its model and what similar vehicles are actually selling for in the second-hand market.
DID YOU KNOW?
One thing most people get wrong: IDV is calculated on the ex-showroom price – not the on-road price. GST, registration and road tax don’t count. Manufacturer-fitted accessories are included; anything aftermarket needs to be declared separately.
Take Priya. She picks up a brand-new Maruti Swift LXi – ex-showroom price ₹8,00,000. Here’s what happens to her IDV over 5 years:
| Policy Year | Vehicle Age | Depreciation Rate | IDV |
|---|---|---|---|
| Year 1 | Under 6 months | 5% | ₹7,60,000 |
| Year 2 | 1–2 years | 20% | ₹6,40,000 |
| Year 3 | 2–3 years | 30% | ₹5,60,000 |
| Year 4 | 3–4 years | 40% | ₹4,80,000 |
| Year 5 | 4–5 years | 50% | ₹4,00,000 |
Priya’s car is stolen at the start of year 2. The insurer pays her ₹6,40,000 – not the ₹8,00,000 she originally paid. That ₹1,60,000 difference isn’t an error or a technicality. It reflects real depreciation on a 2-year-old vehicle. A car that’s been on the road for two years is genuinely worth less – and IDV accounts for that.
But here’s where things go sideways. Say Priya chose a lower IDV at year-2 renewal – ₹5,50,000 instead of ₹6,40,000 – figuring she’d save a bit on premium. She probably saved ₹300–500 for the year. Then the car gets stolen. She receives ₹5,50,000. The remaining ₹90,000? Gone. That’s the trade she made without fully thinking it through.
PRO TIP
Added a music system, custom alloys or a dashcam? Declare them separately. They’re not covered under the standard IDV. Add-on cover for accessories is available and usually inexpensive – worth it for anything of real value.
Your IDV is the base the own-damage (OD) portion of your comprehensive premium is calculated on. The relationship is roughly proportional – push IDV up by 10% and OD premium goes up by about 10% too. Not complicated.

India’s non-life insurance industry underwrote ₹2.90 trillion in direct premium in FY 2023-24 – a 12.76% year-on-year increase. Motor insurance is the single largest segment within this.

Worth knowing though: OD is only part of what you pay. Third-party insurance – the mandatory cover under the Motor Vehicles Act – is set by IRDAI based on engine capacity alone. IDV has zero effect on it. So when you lower the IDV to save money, you’re only trimming the OD component, not the full bill.
For Priya’s year-2 IDV of ₹6,40,000, the OD premium lands somewhere around ₹4,000–5,500 depending on the insurer and any add-ons. Nudge the IDV to ₹7,00,000 and that adds roughly ₹400–600 to the year. Not a dramatic difference. But the extra ₹60,000 in claim cover? That’s very real.
Here’s how it plays out across a range of IDV values for a 3-year-old mid-segment petrol car (1,000–1,500cc). Third-party premium is fixed by IRDAI regardless of IDV [IRDAI – flag for review]. OD rates are indicative – actual figures vary by insurer, NCB and location.
| IDV | OD Premium (~2.5% of IDV) | Third-Party Premium* | Approx. Total Premium |
|---|---|---|---|
| ₹3,50,000 | ₹8,750 | ₹3,416 | ₹12,166 |
| ₹4,00,000 | ₹10,000 | ₹3,416 | ₹13,416 |
| ₹4,50,000 | ₹11,250 | ₹3,416 | ₹14,666 |
| ₹5,00,000 | ₹12,500 | ₹3,416 | ₹15,916 |
| ₹5,50,000 | ₹13,750 | ₹3,416 | ₹17,166 |
| ₹6,00,000 | ₹15,000 | ₹3,416 | ₹18,416 |
Third-party premium for 1,000–1,500cc private cars per IRDAI schedule [IRDAI – flag for review]. OD rates are approximate and vary by insurer, NCB and add-ons. The point: going from ₹3,50,000 IDV to ₹6,00,000 costs you roughly ₹6,250 more per year in OD premium. In return, your total loss cover goes up by ₹2,50,000. That’s a reasonable exchange.
QUICK STAT
Increasing IDV by ₹1,00,000 on a mid-segment car typically adds around ₹2,500 to the annual OD premium – roughly ₹7 a day. The same ₹1,00,000 gap at claim time comes entirely out of your own pocket.

Honestly, there’s no universal answer. It depends on your car, your finances and how much shortfall you’re comfortable carrying. Here’s how to think through it:
PRO TIP
A practical rule of thumb: keep your IDV no more than 10–15% below the actual market value of your car. Going lower saves marginally on premium but creates a significant gap at claim time. Check current resale prices on CarDekho or OLX Cars before deciding.
Want the numbers? Here’s what the IDV trade-off actually looks like in practice. Starting point: ₹6,00,000 IDV – roughly the market value of a 3-year-old mid-segment car.
| IDV Chosen | vs Market Value IDV | Annual Premium Saving | Claim Gap in Total Loss | Years to Break Even |
|---|---|---|---|---|
| ₹6,00,000 (full) | — | — | — | — |
| ₹5,40,000 (−10%) | ₹60,000 under | ~₹1,500/yr | ₹60,000 | 40 years |
| ₹4,80,000 (−20%) | ₹1,20,000 under | ~₹3,000/yr | ₹1,20,000 | 40 years |
| ₹4,20,000 (−30%) | ₹1,80,000 under | ~₹4,500/yr | ₹1,80,000 | 40 years |
WATCH OUT
Notice something? In every row, the years needed to break even on premium savings – through accumulated savings alone – exceeds any realistic ownership period. The maths just doesn’t work in favour of underinsurance.
Each year, IDV falls as the vehicle ages. When the renewal notice arrives, the insurer quotes a figure based on the standard depreciation schedule. That’s a starting point – not a take-it-or-leave-it number. You can push for a higher IDV (and pay a bit more), accept what they offer, or go lower to trim costs. It takes 5 minutes to think through. Most people don’t bother. They just click renew.
That 5-minute inertia is the single biggest reason people end up underinsured. Before you renew, check what similar cars are actually selling for on CarDekho or OLX. If the insurer’s IDV is noticeably below that – ask for a revision. They can usually accommodate it.
Cross the 5-year mark and the formula no longer applies. IDV becomes whatever you and the insurer agree on. They’ll base it on:
For older vehicles, it’s worth shopping around. IDV quotes can vary meaningfully between insurers once the fixed formula is off the table – and a higher IDV from one provider doesn’t always mean a proportionally higher premium. Run a quick comparison on an aggregator before you commit.
IDV – Insured Declared Value – is the maximum payout you receive if your vehicle is stolen or declared a total loss. It represents the current market value of the vehicle after applying IRDAI’s depreciation rates to the original ex-showroom price. Not what you paid for it. What it’s worth now.
Yes, every year. As the vehicle ages, IDV falls in line with IRDAI’s fixed depreciation schedule – from 5% in year one up to 50% by year 5. Beyond 5 years, the table stops applying and IDV is negotiated directly with the insurer.
IDV = Manufacturer’s listed ex-showroom price minus depreciation. The depreciation rate depends on the vehicle’s age – 5% for under 6 months, rising to 50% for a car between 4 and 5 years old. After 5 years, it’s an open negotiation.
Ideally, yes. If the IDV is lower than your outstanding car loan, a total loss settlement won’t fully cover what you owe the lender. You’d need to make up the difference from your own pocket. Many banks and NBFCs require IDV to be at least equal to the outstanding principal – worth checking your loan terms.
No. IDV only applies to the own-damage component of comprehensive motor insurance. Third-party cover is mandatory and its premium is set entirely by IRDAI based on engine capacity – IDV doesn’t come into it at all.
Yes, and you should consider it if your car has held its value well. At renewal, you can request a higher IDV than the insurer’s default quote. You’ll pay a marginally higher OD premium but get meaningfully better protection in a total loss or theft scenario.
You’re underinsured, and the difference is yours to absorb. The insurer pays up to the IDV – not what the car is worth on the open market. This is exactly why reviewing IDV against current resale prices at every renewal matters.
Not exactly. IDV uses a fixed IRDAI depreciation rate applied to the original ex-showroom price. Resale value is what a real buyer would pay today – and for popular models in good condition, that can be noticeably higher than the IDV. When resale value exceeds IDV, you’re already underinsured by default unless you push for a higher IDV.
IDV is calculated using a formula; market value is what someone would actually pay for your car right now. They’re related but rarely identical. For popular models in good condition, market value often exceeds IDV – which is why checking current resale prices before renewal is worth the 5 minutes.
Only in a total loss scenario – not for repairs. In a partial loss claim (accident damage, flood, fire), the insurer pays actual repair costs minus deductibles and part-depreciation. IDV becomes relevant only when repair costs exceed 75% of the IDV, triggering a constructive total loss settlement.
For cars under 5 years old, the base calculation is standardised – IRDAI’s depreciation schedule applies across all insurers. But the final quoted IDV can vary slightly. For vehicles over 5 years, where IDV is openly negotiated, variation between insurers can be meaningful. Always compare rather than accepting the first quote.
Zero depreciation (or ‘nil dep’) is an add-on that removes the depreciation deduction on parts replaced in a repair claim. It doesn’t change your IDV. IDV still caps the payout in a total loss or theft claim. The two serve different purposes – zero dep helps with repair claims; IDV determines the worst-case settlement.
Same formula, same IRDAI depreciation schedule. Ex-showroom price minus the applicable rate based on the bike’s age. Identical to cars – 5% under 6 months, up to 50% between 4 and 5 years. Beyond 5 years, it’s a negotiated figure, same as cars.
For anything over 5 years, IDV is negotiated. For a 10-year-old car, that typically lands somewhere between 15 and 25% of the original ex-showroom price – though it varies significantly by model and how much demand there is in the second-hand market. Compare across at least 2 to 3 insurers before settling.
Yes, within a range. For cars under 5 years old, IRDAI permits IDV to be set within ±15% of the formula value. You can request higher – paying a bit more on OD premium – or go lower to cut costs. Above 5 years, it’s fully open. Use your car’s current resale value as the anchor when you negotiate.
For EVs, the formula is the same – ex-showroom price minus depreciation. But the battery pack is usually the most expensive part of the vehicle and often treated separately by insurers, since it depreciates differently. Before insuring an EV, ask specifically how the battery is valued and whether it’s covered under the standard IDV or needs a separate add-on.
