IDV Calculator 2026 with Premium and Payout Trade-Off

IDV, or Insured Declared Value, is the maximum amount your insurer will pay you if your car is stolen or damaged beyond economical repair in what is called a total loss or constructive total loss. It is effectively the sum insured for the own-damage part of your policy.

The IDV is not what you paid for the car and not its current resale price; it is the manufacturer’s listed selling price reduced by a standard age-based depreciation prescribed under the India Motor Tariff. Because a car depreciates as it ages, the IDV falls at every renewal, which means your total-loss cover shrinks year by year. Getting the IDV right matters a great deal: set it too low and you are under-compensated after a theft or write-off, set it too high and you simply pay extra premium for cover you cannot actually claim, since insurers settle total losses on the vehicle’s genuine value.

IDV is calculated by taking the manufacturer’s listed selling price of your exact make and model and subtracting a standard depreciation percentage based on the vehicle’s age. The depreciation schedule under the India Motor Tariff is 5% for cars up to six months old, 15% from six months to a year, then 20%, 30%, 40%, and 50% for each subsequent year up to five years. So a car listed at 10 lakh rupees that is three years old has 30% depreciation and an IDV of 7 lakh rupees.

If you have accessories that were not fitted by the manufacturer, their value is added to the IDV and depreciated on the same schedule. For vehicles over five years old, the standard schedule no longer applies and the IDV is agreed mutually between you and the insurer based on the car’s condition and market value. This calculator applies the exact tariff schedule and also shows the adjustable band your insurer typically allows.

Yes. The Own Damage premium is charged as a percentage of the IDV, so the relationship is direct and proportional: a higher IDV means both a higher premium and a higher potential payout, while a lower IDV means a lower premium and a lower payout. This is the core trade-off this calculator is built to show.

For example, moving from the recommended IDV to the high end of the band might cost you a couple of thousand rupees more in annual premium but increase your total-loss payout by tens of thousands of rupees. Whether that is worth it depends on your circumstances: a newer car in a high-theft area may justify the higher IDV, while an older car you plan to replace soon may not. The key is to look at the actual rupee figures for premium and payout at each IDV level rather than treating higher or lower as automatically better, which is exactly what the Low, Recommended and High band in this tool lets you do.

To an extent, yes. While the tariff prescribes a recommended IDV from the depreciation schedule, insurers allow you to adjust it within a band, typically around plus or minus 15% of the recommended figure, though the exact range varies between companies. This flexibility exists so you can align the IDV with your car’s actual condition and your own preferences on premium versus cover.

A car in excellent condition with low mileage might justify the higher end, while one with heavy wear might sit lower. However, you cannot set the IDV arbitrarily high to inflate a potential payout, because on a total-loss claim the insurer assesses the vehicle’s real value and will not pay far beyond genuine market worth regardless of a declared figure. The sensible approach is to choose within the band based on your car’s true condition and the premium-versus-payout trade-off, which this calculator displays for the low, recommended and high options.

Your IDV decreases every year because it is based on the vehicle’s depreciating value, and the depreciation percentage applied under the tariff rises with age. A car up to six months old has only 5% depreciation, but by five years the figure reaches 50%, so the IDV of a five-year-old car is roughly half its original listed price.

This mirrors how cars lose value in the real world: a vehicle is worth less each year, so the maximum a total-loss claim can sensibly pay also falls. Some owners are frustrated to see their IDV drop at renewal even when they are willing to pay more premium to keep it high, but the depreciation schedule is standardised across all insurers and cannot be overridden. The practical consequence is that your total-loss protection shrinks over time, which is worth remembering if you have a large outstanding car loan on an ageing vehicle, since the gap between what you owe and what the IDV would pay can widen dangerously.

After five years, the standard depreciation schedule under the tariff stops applying, and the IDV becomes a matter of mutual agreement between you and your insurer. Instead of a fixed percentage, the insurer assesses the vehicle’s current condition, mileage, and prevailing market value to arrive at a fair figure, and you negotiate around that. This is why a well-maintained older car can command a somewhat higher IDV than a neglected one of the same age and model.

For these vehicles, the best practice is to anchor your expectation to genuine resale value, which you can gauge from recent listings for similar cars. This calculator handles vehicles over five years by switching to a market-value input, so you can enter a realistic resale figure and see the corresponding premium band rather than being told the tool cannot help. Just be honest with the figure: declaring an inflated value only raises your premium, because a total-loss settlement on an older car will reflect its real worth, not an optimistic declaration.

Generally no. While a lower IDV does reduce your premium, it also reduces the maximum you can claim on a total loss or theft, and that reduction usually outweighs the premium saving. Consider what you are actually trading: shaving a few thousand rupees off your annual premium in exchange for being paid tens of thousands of rupees less if your car is stolen or written off.

That is a poor bargain for most owners, because the whole point of comprehensive cover is protection against exactly those large, unlikely events. The premium saving from a low IDV is small and certain, while the shortfall on a claim is large and happens precisely when you can least afford it. The only situations where a lower IDV might make sense are when the car is old and low-value anyway, or when you are deliberately self-insuring part of the risk. For most people with a car of meaningful value, choosing the recommended IDV or slightly above is the wiser decision, and this calculator shows you exactly what each option costs and pays.

Accessories are included in the IDV only if they were not part of the manufacturer’s listed selling price and you specifically declare them. Anything fitted by the manufacturer and already reflected in the listed price is automatically covered. But aftermarket additions like a premium sound system, alloy wheels, or other fittings you added yourself are extra, and to insure them you must add their value to the IDV, where they are depreciated on the same age-based schedule as the vehicle.

If you do not declare them, they are simply not covered, so if your car is stolen you would receive nothing for those accessories. This is a common and costly oversight. The trade-off is that declaring accessories raises your IDV and therefore your premium slightly, but it ensures those items are actually compensated on a total loss. This calculator lets you enter the accessories value separately so you can see both the correctly higher IDV and the premium that goes with insuring them properly.

Not exactly, though they are related. IDV is a formula-based figure derived from the manufacturer’s listed price and a standard depreciation schedule, whereas resale value is what a buyer would actually pay in the open market, which depends on condition, mileage, demand, service history, and location. For newer cars within the five-year schedule, the IDV and resale value are often broadly similar but rarely identical, since the tariff depreciation is a standardised approximation rather than a market assessment.

For cars over five years, the two converge more closely because the IDV is then set by mutual agreement based on market value. It is a good idea to sense-check your IDV against recent resale listings for your model: if the IDV looks far out of line with what similar cars are selling for, you may want to adjust within the permitted band. Using resale value as a reality check helps you avoid both under-insuring, where the IDV is too low to compensate you fairly, and over-insuring, where you pay premium for value you cannot recover.

IDV directly determines your payout only on a total loss or theft, not on ordinary partial-damage repair claims. If your car is repairable after an accident, the insurer pays the repair cost, subject to depreciation on individual parts and your policy deductible, and the IDV does not cap that repair payout in the same way. However, IDV still matters indirectly for repairs, because when repair costs approach or exceed a large fraction of the IDV, usually around 75%, the insurer may declare the vehicle a constructive total loss and settle the IDV rather than pay for repairs.

So a lower IDV makes it more likely your car is written off after significant damage, since the repair-to-value ratio crosses the threshold sooner. In that sense, the IDV interacts with your repair claims at the margin. For most routine repairs, though, the relevant factors are the repair estimate, part depreciation, and your deductible rather than the IDV itself, and it is on total losses and theft that the IDV becomes the decisive number.

Yes, the same principle and a similar age-based depreciation approach apply to two-wheelers, so this calculator works for bikes and scooters as well as cars. The IDV of a two-wheeler is its manufacturer’s listed price reduced by depreciation according to its age, and it represents the maximum payout on theft or total loss, exactly as for a car. The main practical difference is scale: two-wheeler values and therefore IDVs are much smaller, so the rupee figures and premiums are correspondingly lower.

The same rules about not under-insuring, declaring accessories, and reassessing older vehicles by market value all apply. Two-wheeler theft is relatively common in many Indian cities, which makes setting an adequate IDV particularly important for bike owners, since a stolen bike is settled at its IDV. To use this calculator for a two-wheeler, simply enter its listed price and age, and the same depreciation logic and premium band will apply, giving you the recommended IDV and the trade-off between cover and premium.

The premium rate is the percentage of your IDV that the insurer charges as the base Own Damage premium, and for comprehensive cover in India it typically falls somewhere between about 2.5% and 3.5%, though the exact figure varies by your car’s engine capacity, its age, your city, and the insurer. Metro cities with heavy traffic and higher theft rates tend to attract rates at the upper end, while smaller towns may see lower rates. If you have a recent quote or renewal notice, you can work out your actual rate by dividing your Own Damage premium by your IDV, and enter that for the most accurate result.

If you do not have that figure, the default of around 3% gives a reasonable illustration. Remember that this rate produces only the base Own Damage premium; your final premium will also include the third-party component fixed by the regulator, any add-on covers you choose such as zero depreciation, and it will be reduced by your No Claim Bonus. This calculator focuses on the IDV-linked Own Damage portion so you can see how IDV choices affect that part directly.

You can request an IDV within the band your insurer permits at each renewal, but you cannot escape the underlying depreciation, so your maximum available IDV falls each year regardless. At renewal, the recommended IDV is recalculated based on your car’s new, older age and the corresponding higher depreciation, and you can then choose within roughly plus or minus 15% of that figure.

So while you can opt for the higher end of the band to keep your cover as generous as the rules allow, you cannot hold the IDV at last year’s level, because the car is now a year older and worth less. This is an important expectation to set: renewing does not reset depreciation. If keeping strong total-loss cover matters to you, choosing the upper end of the permitted band at each renewal is the most you can do, and this calculator shows you what that upper figure is and what premium it carries, so you can make the choice deliberately rather than accepting whatever single number an insurer’s website defaults to.

A constructive total loss is when a vehicle is damaged so severely that the cost of repairing it approaches or exceeds a large proportion of its IDV, at which point the insurer decides it is not economical to repair and instead settles the claim by paying the IDV, treating the car as a write-off. In India this threshold is commonly around 75% of the IDV, meaning if the repair estimate reaches roughly three-quarters of your insured value, the insurer may declare a constructive total loss rather than fund the repairs.

When this happens, you receive the IDV, less any policy deductible and subject to the vehicle’s salvage being handed over, and the car is written off. This is one of the key situations where the IDV becomes the number that matters, because your payout is the IDV rather than a repair cost. It also explains why a lower IDV increases your chance of a write-off after heavy damage: with a smaller IDV, a given repair bill crosses the total-loss threshold more easily, so the vehicle is more likely to be declared a constructive total loss.

No, zero depreciation cover and IDV are two different things that people often confuse. IDV is the total-loss and theft payout, based on the depreciated value of the whole vehicle. Zero depreciation, also called bumper-to-bumper cover, is an add-on that changes how partial-damage repair claims are settled: normally the insurer deducts depreciation on replaced parts according to their material, but with zero depreciation cover you are reimbursed the full cost of those parts without that deduction.

So zero depreciation affects the amount you receive on ordinary repair claims, not the IDV or the total-loss payout. Buying zero depreciation cover raises your premium because it increases the insurer’s exposure on repair claims, but it does not raise your IDV. Both features are worth understanding separately: IDV protects you against the catastrophic loss of the whole car, while zero depreciation protects you against depreciation deductions on the smaller, more frequent repair claims. This calculator deals with the IDV side; zero depreciation is a distinct add-on you choose on top.

The underlying depreciation schedule is standardised under the India Motor Tariff, so for a car within the first five years, every genuine insurer should arrive at broadly the same recommended IDV from the same listed price and age. That is why the recommended figure this calculator produces should closely match what any insurer’s own IDV calculator shows for the same inputs. Where insurers do differ is in three areas.

First, the band they allow you to adjust within can vary, with some permitting a wider range than others around the recommended figure. Second, the base listed price they use as the starting point can differ slightly if they reference different price databases for the same model and variant. Third, for vehicles over five years, where IDV is mutually agreed, there is naturally more variation because it depends on each insurer’s assessment of condition and market value. So while the core depreciation math is uniform, the final IDV you are offered can vary at the edges, which is another reason to understand the recommended figure yourself and treat any single insurer’s number as a starting point for discussion rather than a fixed given.
