What is a Car IDV?

If simply put, IDV is the acronym for Insured Declared Value. In layman terms, it is the current market value of your car, from insurance’s point of reference. It refers to the highest value of money that would be payable by the insurer company per the terms of your vehicle’s insurance policy.

There might be cases where your vehicle may be subject to a total loss or a total constructive loss. It might so happen that it gets stolen, or even gets damaged to a point that it cannot be repaired. In all such cases, the vehicle IDV would be the maximum amount that you can claim from the insurance company.

Why is IDV important?

IDV is very crucial in determining the actual value of your car. In case you suffer any mishappening or damages, you are eligible to get the maximum financial protection if you know your vehicle’s IDV. 

A high IDV constitutes a higher premium you need to pay to buy a policy or insurance. It can be a hassle at first, but it justifies the price tag in the long run. On the flip side, undervaluing your vehicle’s IDV may seem a smart idea at first, but it can hamper the car’s actual market value, and it significantly drops the insurance rates as well. 

What is IDV Calculator?  

IDV calculator is a tool used by car owners to estimate the IDV of their vehicles. As the importance of IDV has increased prominently in the last couple of years, the usage for the IDV calculators has also risen. You need to fill in specific details, such as Age of your vehicle, and the number of kilometres it has piled up to calculate the exact amount of market depreciation it has faced and the remaining value. 

How does IDV affect your car insurance?

IDV can affect you in several ways; 

  • Firstly, you have to calculate the actual IDV of your vehicle, without overestimating or underestimating its value. If you overvalue your car’s IDV, then you may have to pay a higher sum of premium to receive the insurance. 
  • An undervaluing IDV can lead to an instant downfall in the vehicle’s market value. IDV also helps in deciding the right insurance slab with apt policy selection and justifiable premiums.

IDV Calculate Table

The following is a universal IDV calculate table used by manufacturers to compute an accurate IDV for your vehicle:

Age of Vehicle % Depreciation for adjusting IDV
Not exceeding 6 months


Exceeding 6 months but not exceeding 1 year


Exceeding 1 year but not exceeding 2 years


Exceeding 2 years but not exceeding 3 years


Exceeding 3 years but not exceeding 4 years


Exceeding 4 years but not exceeding 5 years


The table depicted above can help in calculating the IDV. If your car is less than six months old, then depreciation will be less than 5%, mainly because the engine is still fresh and many safety policies by manufacturers are still backing the vehicle.

The depreciation rates take a toll after six months, as the overall structural integrity starts to vary out. After exceeding one year, the depreciation rate increases to 20%, due to many manufacturers’ safety policies being exhausted by this time period. 

This rate keeps exceeding by 10% each year under it exceeds the 5-year mark. After that, you need to reevaluate your vehicle from any vendor or manufacturer in order to get the actual market price.

How to Calculate Car IDV

To determine vehicle IDV, proper calculations are to be done. To do the same, the insurance companies usually operate on certain easily available parameters and then adjust those with the standard available car depreciation rates, set by the Indian Motor Tariff. The factors are listed below:

  • First purchase or registration date of the vehicle available on the registration certificate
  • City where the vehicle was registered, also available on the registration certificate
  • Current registration type- company owned or individual owner
  • Ex- showroom price i.e. the actual price of the car with addition to the state tax
  • Manufacturer, make and model of the vehicle
  • Cubic capacity, which is based on the model details
  • Vehicle description, which is also based on the model details

How Car Valuation is Different from Car IDV?

While car IDV determines the value of your car, it does so strictly for insurance purposes. On the other hand, car valuation is the market value of your car, which you can get if you wish to sell it. It differs from the IDV as the considerations for both are different. Car valuation also depends upon the demand and supply of your car.

For example, the IDV of your vintage car might be extremely low, but its car valuation will be very high since it is rare. Also, the car valuation depends upon the condition of your car and its engine, whereas the IDV would only go by the age of the car and not its conditions.

Therefore, IDV though similar in nature, is starkly different from car valuation.
