Vehicle Depreciation Rates: Meaning & Impact on Car Insurance
Key Highlights
  • Vehicle depreciation is the gradual loss of a car's value over time.
  • A new car can lose around 10%-15% of its value soon after leaving the showroom.
  • The first year usually sees the biggest drop in value.
  • Standard depreciation rates increase as the vehicle gets older.
  • Depreciation affects a car's resale value and its Insured Declared Value (IDV).
  • During insurance claims, depreciation deductions vary by the material being replaced.
  • Zero-depreciation cover can reduce or remove depreciation deductions on eligible parts.

A car starts losing value from the moment it becomes a used vehicle. Age, mileage, maintenance and market demand all play a role in how much its value falls over time. This reduction is known as vehicle depreciation.

A new car can lose around 10% to 15% of its value soon after leaving the showroom. The first year often sees the sharpest fall, with some cars losing 30% or more of their original value.

Many people think that depreciation is only important when selling a car. But it is not the truth. It also affects car insurance through the vehicle's IDV and deductions made during certain claims.

This blog discusses car depreciation rates and their impact on your insurance decision.

What Is Vehicle Depreciation?

Vehicle depreciation means the reduction in a car's market value over time.

As a car gets older, it becomes less valuable than when it was new. Regular use, wear and tear, and changes in market demand all contribute to this fall in value.

The usual pattern looks like this:

New car Sharp drop in value Gradual depreciation Slower value loss after several years

After around four to five years, many vehicles are worth roughly half of their original price. The rate of depreciation then usually becomes slower.

The exact rate varies from one car to another.

Standard Car Depreciation Rates

The following rates are commonly used for vehicle depreciation in insurance calculations.

Age of Vehicle Depreciation Rate
Less than 6 months 5%
6 months–1 year 15%
1–2 years 20%
2–3 years 30%
3–4 years 40%
4–5 years 50%
Over 5 years Based on the vehicle's market value

These rates are used as a standard reference for insurance purposes. A car's actual resale value can still vary depending on its condition, mileage, and demand.

How Is Vehicle Depreciation Calculated?

A simple formula to calculate depreciation using the motor vehicle depreciation rate.

“Manufacturer’s List Price × Rate of Depreciation declared by IRDAI ÷ 100”

Factors That Affect Vehicle Depreciation

Here are some of the key factors that affect vehicle depreciation:

Age and Mileage

  • Age is one of the most significant factors. Older vehicles generally lose more value because they have been used for a longer period.
  • Mileage also matters. A car that has travelled many kilometres often experiences more wear and tear, which can lower its resale value.

Make and Model

Popular models often retain their value better.

Cars with strong demand in the used-car market usually depreciate more slowly than models that buyers are less interested in.

Condition and Maintenance

A well-maintained car usually holds its value better.

Regular servicing, good tyres and a clean interior can help preserve the car's condition.

On the other hand, accident history, visible damage and poor maintenance can reduce its value faster.

Market Demand

The used-car market also affects depreciation.

If demand for a particular model remains strong, its resale value can stay relatively higher.

Lower demand can lead to faster depreciation.

How Depreciation Affects Your Car's Resale Value

Depreciation directly affects the price you can expect when selling your car.

For example, a vehicle bought for Rs 10 lakh will not usually sell for the same amount after several years.

The final selling price depends on factors such as:

  • Age
  • Mileage
  • Condition
  • Service history
  • Accident history
  • Model popularity
  • Market demand

The higher the depreciation, the lower the expected resale value.

Understanding depreciation can help you estimate how much your car could be worth in the future.

How Does Vehicle Depreciation Affect Car Insurance?

Depreciation also plays an important role in car insurance.

It mainly affects:

  • The Insured Declared Value (IDV)
  • Certain repair claim calculations

Impact on IDV

The Insured Declared Value (IDV) is the approximate value of the insured vehicle.

It becomes especially important if the car is stolen or declared a total loss, subject to the policy terms.

As the car gets older, its value generally falls. The IDV also reduces accordingly.

A lower IDV means the maximum payout in an applicable theft or total-loss claim can also be lower.

That is why it is important to check the IDV while buying or renewing car insurance.

Impact on Repair Claims

Depreciation can also affect repair claims.

When damaged parts are replaced after an insured accident, depreciation deductions can apply to eligible components depending on the policy.

This means the insurer might not pay the full replacement cost of every part under a standard policy.

Material-Wise Depreciation on Car Insurance Claims

Different materials attract different depreciation deductions during partial claims.

Part or Material Depreciation Deduction
Rubber, nylon, plastic items, batteries and tyres 50%
Fibre glass components 30%
Wooden parts 5%
Metal parts Based on the vehicle's age

What Is Zero-Depreciation Car Insurance?

Zero-depreciation cover is an optional add-on available with many car insurance policies.

It is designed to reduce or eliminate depreciation deductions on eligible parts during covered claims, subject to the policy's terms and conditions.

For example, if a covered plastic or fibre component needs replacement after an accident, a standard policy can apply depreciation. With a zero-depreciation add-on, the deduction for eligible parts can be reduced or removed.

This can result in a higher claim payout.

However, zero-depreciation cover does not stop the car from losing market value.

The vehicle continues to depreciate with age and use. The add-on only changes how depreciation is treated while calculating eligible insurance claims.

Market Depreciation vs Insurance Depreciation

These two terms are related, but they are not the same.

Market Depreciation Insurance Depreciation
Reduction in the car's resale value Depreciation considered under the insurance policy
Affects what the car can sell for Can affect IDV and certain claim calculations
Depends on age, mileage, condition, and demand Depends on policy terms and applicable depreciation rules
Relevant when selling the car Relevant when buying insurance or making claims

How Can You Reduce the Impact of Depreciation?

You cannot completely stop a car from depreciating, but you can slow the loss of value.

Maintain the Car Regularly

Follow the recommended service schedule and keep maintenance records.

A well-maintained vehicle usually retains value better.

Keep the Car in Good Condition

Avoid unnecessary damage and repair dents or scratches promptly.

The better the car looks and performs, the stronger its resale value is likely to be.

Check the IDV During Renewal

Do not focus only on the insurance premium.

Check the IDV and understand how it reflects your car's current value.

Consider Zero-Depreciation Cover

If your car is eligible, compare the cost and benefits of a zero-depreciation add-on.

Check the coverage, exclusions, and claim limits before buying it.

Why Should Car Owners Understand Depreciation?

Depreciation affects more than the resale price of your vehicle.

It can influence:

  • Future selling value
  • Insurance IDV
  • Repair claim payouts
  • The usefulness of a zero-depreciation add-on
  • The overall cost of owning a car

Understanding how depreciation works can help you make better decisions when selling your car or renewing its insurance.

Conclusion

Vehicle depreciation is the gradual loss of a car's value as it ages and is used. The biggest drop usually happens during the first few years, after which the rate of value loss tends to slow.

Depreciation also affects car insurance. It influences the IDV and can lead to deductions on certain parts during repair claims. The amount deducted depends on the material being replaced, with different rates applying to plastic, fibre glass, wooden and metal components.

For car owners, it is useful to understand how depreciation works, check the IDV at every renewal and know how depreciation deductions affect claims. If reducing those deductions is important, a zero-depreciation add-on can be worth considering.
