9.  Frequently Asked Questions About IDV in Motor Insurance 

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. 

Why Does IDV Matter for Your Motor Insurance Policy? 

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.  (Source: Mordor Intelligence Motor Insurance Report, 2025) 

How Is IDV Calculated in India? 

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. *(Source: IRDAI India Motor Tariff, GR-8)* 

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. 

IDV Calculation Example: Priya’s Maruti Swift 

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. 

What Is Included and Excluded in IDV? 

Included in IDV 

• Ex-showroom price of the vehicle 

• Manufacturer-fitted accessories that come standard with the variant — such as a factory-installed sunroof, alloy wheels or rear camera 

Excluded from IDV 

• GST, registration charges and road tax 

• Aftermarket and custom accessories (music systems, custom alloys, roof racks, tinted glass) 

• Electrical or electronic fittings not factory-installed 

• CNG or LPG bi-fuel kits — these must be separately insured under an add-on 

• Tyres and tubes beyond the manufacturer’s standard fitment 

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. 

IDV and Your Insurance Premium: What’s the Link? 

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. 

QUICK STAT 

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. *(Source: IRDAI Annual Report 2023-24)*  (Source: IRDAI Annual Report 2023-24) 

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.  (Source: Indicative calculation based on ~2.5% OD rate) 

Should You Choose a Higher or Lower IDV? 

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: 

Choose a Higher IDV If: 

• Your vehicle is relatively new — under 3 years old 

• You live in an area with elevated theft risk 

• You have an outstanding car loan — most lenders require the IDV to cover at least the outstanding principal 

• You cannot afford to absorb a large financial shortfall in a total loss scenario 

Choose a Lower IDV If: 

• Your vehicle is older — 5 years or more — with low resale value 

• You have a strong emergency fund and are comfortable self-insuring the gap 

• The vehicle is rarely used and the likelihood of theft or total loss is low 

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. 

What Happens to IDV at Policy Renewal? 

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. 

IDV for Vehicles Older Than 5 Years 

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: 

• Make, model and variant of the vehicle 

• Current second-hand market prices for that model and age 

• The vehicle’s condition, mileage and service history 

• Prevailing insurer market surveys 

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.

Frequently Asked Questions About IDV in Motor Insurance 

Q1:  What does IDV stand for in motor insurance? 

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. 

Q2:  Does IDV decrease every year? 

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. 

Q3:  What is the formula for IDV calculation in India? 

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. 

Q4:  Should IDV be higher than my outstanding car loan amount? 

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. 

Q5:  Does IDV apply to third-party motor insurance? 

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. 

Q6:  Can I increase my IDV at renewal? 

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. 

Q7:  What happens if my car is worth more than the IDV at claim time? 

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. 

Q8:  Is IDV the same as the resale value of my car? 

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. 

Q9:  What is the difference between IDV and market value? 

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. 

Q10:  Does IDV apply in a partial loss claim — not just total loss? 

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. 

Q11:  Is IDV the same across all insurers, or does it vary? 

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. 

Q12:  What is zero depreciation cover and how does it differ from IDV? 

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. 

Q13:  How is IDV calculated for a two-wheeler? 

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. 

Q14:  What is the IDV for a car older than 10 years? 

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. 

Q15:  Can I negotiate IDV with my insurer? 

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. 

Q16:  How does IDV work for electric vehicles (EVs)? 

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.
