Two identical cars can have different insurance premiums, and the reason often comes down to the Insured Declared Value (IDV). It is a car's insured market value, showing how much a policyholder pays in premiums relative to what they receive if their car is stolen or totalled.
Get it right, and the policyholder is well protected. Get it wrong, and they could end up either overpaying or underinsured.
An IDV Calculator is an online tool that provides an estimate of how much your car is worth, using information like the brand, model, trim level, year, and depreciation rate.
The Insured Declared Value (IDV) of your vehicle is the most you will receive if your vehicle is either written off (total loss) or stolen. As a vehicle depreciates over time, the IDV also depreciates each year.
The Car Insurance Calculator takes the headache out of calculating your car's depreciation each year. The IDV calculator uses the information you enter to provide an approximate value for your car, rather than requiring you to manually calculate it using a table created by the IRDAI.
Note: The calculated IDV is indicative, and the final IDV may vary slightly depending on the insurer’s internal guidelines and verification.
The IDV of a car is calculated using a formula defined by the Insurance Regulatory and Development Authority of India (IRDAI):
IDV = Manufacturer's Listed Selling Price − Depreciation + Value of Accessories (if not included in listed price) − Value of Accessories (if included but not insured)
In most standard cases, the formula simplifies to:
IDV = Ex-Showroom Price − Depreciation (based on vehicle age)
For example, if your car has an ex-showroom price of ₹10 lakh and is 2 years old, a 20% depreciation rate would apply, bringing the IDV to approximately ₹8 lakh.
It is important to note that the ex-showroom price, not the on-road price, is used as the base value. Registration fees, road tax, and insurance are excluded from the IDV calculation. Additionally, the value of parts that are not manufactured, such as tyres and tubes, is calculated separately, with a 50% standard depreciation applied to them.
The IRDAI has established standard depreciation rates that insurers use to calculate a vehicle's IDV based on its age. As a car ages, its depreciation rate increases, reducing its IDV. Understanding these rates can help car owners anticipate how their vehicle's insured value will change over time and plan their insurance coverage decisions more effectively.
| Vehicle Age | Depreciation Rate |
|---|---|
| Less than 6 months | 5% |
| 6 months to 1 year | 15% |
| 1 year to 2 years | 20% |
| 2 years to 3 years | 30% |
| 3 years to 4 years | 40% |
| 4 years to 5 years | 50% |
| More than 5 years | To be mutually agreed upon by the insurer and the policyholder |
Note: For vehicles older than five years, or for discontinued car models, the IDV is determined by mutual agreement between the insurer and the policyholder, often based on a market survey of the vehicle's prevailing value.
| Car Model | Approx. Ex-Showroom Price | IDV (1 Year Old) | IDV (3 Years Old) | IDV (5 Years Old) |
|---|---|---|---|---|
| Maruti Suzuki Swift | ₹7.5 lakh | ₹6.4 lakh | ₹4.9 lakh | ₹3.6 lakh |
| Hyundai Creta | ₹11 lakh | ₹9.4 lakh | ₹7.1 lakh | ₹5.2 lakh |
| Tata Nexon | ₹10 lakh | ₹8.5 lakh | ₹6.4 lakh | ₹4.7 lakh |
| Honda City | ₹12 lakh | ₹10.2 lakh | ₹7.7 lakh | ₹5.6 lakh |

Below are the Key Benefits of Using an IDV Calculator.
It gives a quick estimate of the IDV. This means you no longer need to calculate depreciation to manually estimate your vehicle's IDV.
The car insurance calculator helps you better understand how much your car is likely to be worth at the time of a total loss or theft.
Since the insurance premium is partly based on the IDV, the Car Insurance Calculator helps estimate how changes to the IDV may affect the premium.
Since the premium is partially based on the IDV, using the calculator will give you an idea of how a change in IDV will affect your policy premium.
Vehicle owners can determine whether the IDV offered aligns with the car’s expected market value.
Car insurance premium and insured declared value go hand in hand. Higher the IDV, higher is the car insurance premium and vice versa. As the value of your car depreciates, the premium also decreases. At the time of selling the car, you will get a higher price if the IDV of the car is high. However, factors such as condition of the car, usage, past car insurance claims, etc. are also taken into consideration.
To attract a low premium, you would set a low IDV for your car, but at the time of theft or total loss, a lower IDV will get you a low claim amount. In case of a higher IDV, you are eligible to receive a higher compensation.
IDV is important for a car insurance policy, influencing everything from the coverage a policyholder receives to the premium they pay. It establishes the maximum claim amount payable in the event of total loss or theft, meaning the higher the IDV, the greater the financial protection available.
IDV also directly affects the insurance premium. Generally, a higher IDV results in a higher premium, since the insurer's potential liability is greater. It is therefore important for policyholders to set an IDV that accurately reflects the car's depreciated market value, rather than inflating or deflating it arbitrarily.
Beyond claim payouts and premiums, IDV represents the vehicle's current value in the insurer's eyes. Keeping it aligned with the actual market value helps policyholders avoid two common pitfalls: under-insurance, where inadequate compensation is received at claim time, and over-insurance, where unnecessarily high premiums are paid for coverage beyond the vehicle's real worth. In situations involving very large claims, a well-calibrated IDV ensures that the compensation received is genuinely sufficient to cover the financial loss incurred.
| IDV Type | Advantages | Disadvantages |
|---|---|---|
| Higher IDV | Higher claim payout in case of total loss or theft. Coverage closer to the vehicle’s current market value | Higher insurance premiums that might increase the overall policy cost |
| Lower IDV | Lower insurance premiums with reduced policy costs during renewal | Lower claim amount if the vehicle is declared a total loss. Potential risk of under-insurance |
Choosing a Higher IDV may be suitable when:
The car is new or relatively new
The vehicle has a high market value
The vehicle is used in areas with higher theft or accident risk
The owner prefers higher financial protection
Choosing a Lower IDV may be suitable when:
The car is older and significantly depreciated
The owner wants to reduce premium costs
The vehicle has a lower resale value
Given below are few factors that determine the insured declared value of your car
Insurance companies consider the age of your car when determining the premium as older the car, lesser is the market value i.e. its insured declared value and vice versa.
The make and model of your car has a huge influence on its IDV. The cost of insuring a high end car like a Lamborghini would be higher than that of a Hyundai or Maruti car. High end luxury cars require higher cost and maintenance owing to which the insurance cost is higher.
This refers to the city in which your car is registered. For instance, the IDV of a car will be higher in metro cities like Mumbai, Pune, Delhi since the car would be open to more risks in traffic than ones running in smaller towns.
The value of your car depreciates as it ages; it depreciates in the form of percentage based on its age as mentioned in the above table.
When calculating the IDV of your car, keep in mind the below important things.
Selecting an appropriate IDV helps maintain the balance between insurance cost and financial protection.
You can assess the most appropriate IDV of a vehicle by several factors:
Vehicle age: An older vehicle has a lower IDV because of depreciation.
Current market value: IDV should reflect the vehicle's current market value.
Usage conditions: If the vehicle is used frequently or in high-risk areas, you may want a higher IDV.
Premium affordability: The higher your IDV, the higher your premium, so this factor should be considered when determining whether you can afford it.
Insurer limits: The IDV must remain within the insurer's approved range.
IDV plays an important role in determining the claim amount during major insurance events.
If a vehicle is damaged beyond repair after an accident, the insurance company may deem it a total loss. So, the claim payout will usually be based on the policy's IDV and other terms.
If the insured vehicle is stolen and not recovered, the insurance company will typically pay the IDV listed in the policy.
A Constructive Total Loss occurs when the cost of repairs to your vehicle exceeds a certain percentage of its IDV, typically 75%. At that point, the insurance company will declare your vehicle a Total Loss and pay the IDV as compensation.
IDV typically decreases at each policy renewal because vehicles depreciate over time.
Insurance companies will typically reevaluate the Insured Declared Value (IDV) of a car at the time it is renewed based on the following factors:
How long have you owned your vehicle
How much the vehicle has depreciated
What type of vehicle do you own (model and variant)
Key things to confirm at the time of renewal:
The IDV on the insurance policy
The IDV across different quotes
To see if the policy reflects the market value of the car
To understand the coverage, including any add-on coverage, on the insurance policy you are getting a new renewal for.
Several misconceptions exist regarding a Car Insurance Calculator.
“Higher IDV always means better coverage”
A higher IDV increases the claim limit but also increases the premium. The right IDV should balance cost and coverage.
“Lower IDV only reduces premium, not claim value”
Due to your IDV being lower, you will pay less in insurance and have a lower max claim.
“IDV stays the same throughout the insurance period”
Vehicle depreciates from the date of purchase to the date you are renewing, and at that time, we would recalculate your IDV.
“IDV equals resale value”
IDV is a calculated amount used for insurance purposes. It is determined by applying depreciation guidelines; however, in some instances, IDV may not equal the vehicle's resale value.
“Insurers reduce IDV unfairly”
Most insurers will follow standard depreciation methods to calculate IDV and subsequent reductions to IDV.
Insurance companies reduce the IDV of the car to attract less premium. However, when paying a premium for the policy, always check on the insured declared value as you need to choose the right IDV which is equivalent to the value of your car.
Higher the insured declared value, higher the car insurance premium and vice versa. The cost of insuring a car having a high market value is higher and hence is the premium.
Opting for a higher IDV is a good option only if you own a luxury car, the spare parts of your car are expensive, or if you are willing to pay a higher premium and are looking for more coverage.
If an individual declares a low IDV, he will have to pay less premium. However, the claim amount he will get at the time of total loss or theft of the car will also be less.
Factors such as car registration details, make and model of the car, age of the car, and depreciation rates have a great impact on the calculation of the IDV.
Insured declared value refers to the existing market value of your car minus the depreciation factor which is calculated based on its age.
When you purchase a new car and take it outside the showroom, its value depreciates by 5% directly.
Yes, at the time of policy purchase, you can choose to increase the IDV of the car. However, it is necessary to declare the correct IDV.
Yes, IDV of your car is impacted based on the location as different cities and states in India have different ex-showroom prices of the car.
Opting for a high IDV is a wise choice only if you have an expensive car.
IDV is calculated based on the age of the car and the standard depreciation rates mentioned below.As the car ages, its value starts depreciating.
Car age 6 months & below: 5% depreciation
Car age 6 months to 1 year: 15% depreciation
Car age 1 year to 2 years: 20% depreciation
Car age 2 years to 3 years: 30% depreciation
Car age 3 years to 4 years: 40% depreciation
Car age 4 years to 5 years: 50% depreciation
For cars above 6 months, IDV reduces by 10% each year
IDV in car insurance refers to insured declared value i.e. the total market value of your car; it is the amount you would be eligible to receive in today’s times in case of sale of the car.
The ideal IDV should closely match the car's depreciated market value, providing adequate coverage without significantly increasing the premium. Choosing an IDV that is too low may lead to insufficient compensation in case of theft or total loss. At the same time, an unnecessarily high IDV can increase your premium without offering proportionate benefits.
Policyholders may select an IDV within the insurer's allowed range, usually a small percentage above or below the calculated value. This flexibility helps balance premium costs with the level of coverage required.
The IDV payout is the maximum amount the insurance company is obligated to pay an individual if their vehicle is stolen or written off as a total loss; the figure depends on the insurance policy. The final payout may be adjusted after deducting the applicable excess or deductibles.
According to depreciation rules, the IDV usually goes down after two years and may drop to about 70 to 80% of the original value of the vehicle, depending on the depreciation schedule. Regular renewal helps ensure the revised IDV remains accurate.
The claim amount cannot exceed the IDV specified in the policy, except when deductibles or policy conditions apply. In total loss or theft cases, the insurer settles up to this maximum insured amount. For partial damage claims, the payout depends on the repair estimate and policy terms.
You can slightly increase the IDV during policy purchase or renewal, as long as it falls within the insurer's permissible range. This can be useful if the car has retained strong resale value or includes valuable accessories. However, increasing the IDV also leads to a higher insurance premium.
The calculation method is similar, but depreciation rates, vehicle usage, and insurer policies may vary between commercial and private vehicles. Commercial vehicles often experience higher wear and tear due to frequent usage, which can impact the IDV more significantly.
