Purchasing a car or bike is a huge investment in your life. But at the same time, you have to understand that with time the car ages and its value depreciates. As soon as you bring your vehicle out of the showroom, the value depreciates by 5% and gradually keeps on falling with each passing year. This depreciation amount is generally considered when you buy or claim insurance for your car or bike.

Therefore, in this article, we will be guiding you in detail on how depreciation on your car or bike is calculated, as well as provide some examples. 

Depreciation Rate For Cars And Bikes

When you buy a car or bike, its value diminishes slowly with time due to natural wear and tear. This phenomenon is known as depreciation. It is the reduced estimated value of a fixed asset within a financial year.

The bike depreciation rate chart is the same as the one for cars. 

Significance Of Insured Declared Value (IDV)

The main purpose of insured declared value (IDV) is to assist you in determining the resale value of your vehicle. The prime objective of IDV is to calculate the policy premium. It also determines the sum that the insurer will pay if your vehicle is irreparably damaged or stolen. Keep in mind that a lower IDV translates to a lower policy premium, whereas a larger IDV equates to a higher policy premium. Therefore, you should keep your IDV as close to your bike's present market value as possible.

Depreciation Rate Of Cars And Bikes After 5 Years

The value of your car or bike continues to decrease after five years, although being dependent on its condition and serviceability. After five years, your vehicle is generally considered obsolete. So, the rate of depreciation is applied accordingly.

For car depreciation rate after five years, the rate gets mutually decided by the insurance provider and owner. To calculate IDV, the car owner and insurance provider mutually decide on a specific range. 

For the bike depreciation rate after five years, the applicable rate to calculate IDV is mutually decided by the policyholder and insurance provider in order to avoid discrepancies.

What Is Zero Depreciation In Car Insurance?

Zero depreciation in car insurance or nil depreciation cover is an add-on where the insurance company does not charge any depreciation for the insured car. The policyholder can claim the total cost of replacing any car parts for accidental damage. Moreover, the depreciation value for any damaged parts is not deducted before the amount is claimed.

By adding zero depreciation to your car insurance, you can claim several benefits, such as: 

  • Save better with high payouts covering the depreciation of your car and damaged parts.
  • No depreciation is charged while settling an insurance claim, helping you to claim a higher amount.
  • The price of this add-on is way less in comparison to the benefits it provides.

How To Calculate Car Depreciation?

Indian insurance companies on their official websites provide car depreciation or IDV calculators. This tool effectively computes your vehicle's depreciation, allowing you to evaluate its worth depending on different parameters. The IDV calculator instantly furnishes proper assessment based on your car's age, condition, and mileage. 

This feature is useful when selling or insuring a used vehicle. Furthermore, using the tool is pretty simple. Just enter your vehicle's registration number, year of manufacture, brand, model, and city of residency to calculate the depreciation of your car.

How To Calculate Bike Depreciation?

To calculate the depreciation of your bike, you can use IDV calculators available on the websites of different insurance providers. The IDV of your bike is generally not calculated based on the price of the vehicle during purchase. This calculator considers its market value from the commencement of the policy. The value tends to vary significantly with time and usage.

Depreciation Rate Formula For Cars

The formula to calculate the depreciation of your car includes two different methods. They are as follows:

  • Diminishing value technique

The formula to calculate the depreciation of your car using the diminishing value technique is:

Purchase value of car * (number of days car owned ÷ 365) * (effective life in years ÷ 200%)

Note: Here, depreciation is calculated considering the base value of the car.

  • Prime cost technique

The formula to calculate the depreciation of your car using the prime cost technique is:

Cost of running the car * (number of days car owned ÷ 365) * (100% ÷ effective life in years)

Note: Here, depreciation is calculated as a particular percentage of the total cost.

Depreciation Rate Formula For Bikes

To calculate the depreciation of your two-wheeler, you can use the following formula:

IDV (insured declared value) = [Current market value of your bike- depreciation costs] + [accessories cost - depreciation value of accessories]

However, if you do not have any accessories attached to the bike, the formula to calculate depreciation is:

IDV = Manufacturer’s registered cost of bike - Depreciation value

Note: It is important for you to appropriately understand the influence of depreciation percentage on your bike's age, to comprehend its IDV.

Example Of Depreciation For Cars

Suppose you purchased a car worth Rs.5,50,000. After two years, its current market value is Rs.5,20,000. If you wish to calculate your IDV during this period, the depreciation rate applicable is 20%.

Therefore, the IDV of your car will be:

IDV at 80% (on Rs.5,75,000) = Rs.4,16,000

Example Of Depreciation For Bikes

Assume the market worth of your bike is Rs.5 lakh while purchasing the bike insurance policy. Here your insurer will reimburse the maximum amount you choose as an IDV if your bike suffers total damage or irreparable loss. It is critical to understand that you may only claim for the IDV if your bike gets stolen or severely damaged during the policy period.

Final Word

The depreciation value of your car or bike depends heavily on the brand, model, and price. Using an online car or bike depreciation calculator accessible from several insurers will help you consider what worth your vehicle presently retains, depending on the current market pricing. Thus, whether you intend to sell a car or bike or get it insured, you must account for all depreciating factors.
