How Excess and Deductible Terms Impact Car Insurance Claims

When buying car insurance, many policyholders focus on the premium, Insured Declared Value (IDV), add-ons and coverage limits. However, another important factor that directly affects the amount received during a claim is the deductible, also commonly referred to as an excess.

A deductible is the portion of an eligible claim that the policyholder has to bear before the insurer pays the remaining amount, subject to the policy terms. IRDAI advises vehicle owners to compare deductibles along with coverage and IDV because a lower premium may sometimes be associated with a higher deductible or lower coverage.

Understanding how compulsory and voluntary deductibles work can help car owners estimate their potential out-of-pocket expenses before making a claim.

What Is a Deductible or Excess in Car Insurance?

In motor insurance, a deductible or excess is an amount that the insured agrees to bear when an eligible claim arises.

For example, suppose the admissible repair cost after an insured accident is ₹40,000 and the applicable deductible is ₹2,000. If all other policy conditions are satisfied, the insurer may pay ₹38,000, while the policyholder bears ₹2,000.

The actual settlement can also be affected by other factors, such as depreciation, policy exclusions, sub-limits, uncovered expenses and the applicable IDV.

Therefore, the deductible should not be confused with the total amount of damage suffered.

Compulsory Deductible

A compulsory deductible is the portion of an eligible claim that the policyholder must bear according to the policy terms.

IRDAI’s motor insurance guidance explains that a standard compulsory excess applies to motor policies, with the applicable amount depending on factors such as the type and characteristics of the vehicle.

The compulsory deductible is generally applicable to covered own-damage claims according to the policy wording. It is not an optional amount that the policyholder can simply remove at the time of making a claim.

For example, if the applicable compulsory deductible is ₹2,000 and the admissible own-damage claim is ₹25,000, the deductible can reduce the insurer’s payable amount to ₹23,000, assuming there are no other deductions.

Policyholders should always check the exact amount stated in their policy schedule.

Voluntary Deductible

A voluntary deductible is an additional amount that the policyholder chooses to bear over and above the compulsory deductible.

In return for accepting a higher out-of-pocket contribution, the policyholder may receive a reduction in the applicable own-damage premium. IRDAI specifically identifies opting for a voluntary additional deductible/excess as one factor that can result in a premium discount.

For example:

• Compulsory deductible: ₹2,000
• Voluntary deductible: ₹3,000
• Total deductible: ₹5,000

If an eligible claim is assessed at ₹30,000, the insurer’s payment could be ₹25,000 before considering other applicable deductions.

The exact treatment depends on the policy wording.

How Deductibles Affect the Final Claim Amount

The simplest way to understand the impact is through an example.

Suppose a car is involved in an accident and the insurer assesses an eligible repair loss of ₹50,000.

Particulars	Amount
Admissible repair cost	₹50,000
Compulsory deductible	₹2,000
Voluntary deductible	₹3,000
Total deductible	₹5,000
Amount after deductible	₹45,000

In this simplified example, the policyholder bears ₹5,000 and the insurer’s liability before any other applicable adjustments is ₹45,000.

However, actual claim settlements may involve depreciation or other policy-specific deductions. Therefore, the final amount should not be calculated solely by subtracting the deductible.

Small Claims Can Be Affected More Significantly

Deductibles can have a relatively larger impact on smaller repair claims.

Consider two claims:

Claim A: ₹10,000 loss with a ₹2,000 deductible
Claim B: ₹1,00,000 loss with a ₹2,000 deductible

In the first case, the deductible represents 20% of the admissible claim. In the second case, it represents only 2%.

This illustrates why policyholders should understand their deductible before deciding whether a minor repair should be claimed under the policy or paid personally. A claim can also have implications for future premiums or No Claim Bonus (NCB), depending on the policy and circumstances.

Deductible Is Different From Depreciation

Deductible and depreciation are two different concepts.

A deductible is the amount the policyholder is contractually responsible for under the policy.

Depreciation relates to the reduction in the assessed value of certain vehicle parts because of age and usage, subject to the applicable policy terms.

For example, a claim could involve:

• Repair cost: ₹60,000
• Depreciation adjustment: ₹8,000
• Deductible: ₹2,000

The final payable amount could therefore be affected by both the depreciation adjustment and deductible.

This is one reason a policyholder should not assume that the insurer will simply pay the repair bill minus the deductible.

Deductible and IDV Are Also Different

The Insured Declared Value (IDV) represents the insured value of the vehicle for own-damage purposes and is particularly relevant in situations such as total loss or constructive total loss.

The deductible, by contrast, represents the policyholder’s agreed contribution toward an eligible claim.

A lower IDV does not mean a lower deductible, and a higher deductible does not increase or decrease the vehicle’s IDV automatically.

IRDAI recommends comparing IDV and deductibles alongside coverage when purchasing motor insurance.

Why a Higher Deductible Can Reduce Premium

A voluntary deductible transfers a larger portion of potential claim costs to the policyholder.

Because the policyholder agrees to bear more of the loss, the insurer may offer a premium discount on the relevant own-damage coverage.

However, a lower premium should not be considered in isolation.

For example, two policies may have similar coverage but different premiums:

Feature	Policy A	Policy B
Annual premium	₹12,000	₹10,500
Deductible	₹2,000	₹5,000
Potential out-of-pocket cost	Lower	Higher

The cheaper policy may require the policyholder to contribute more when a claim occurs.

This is why IRDAI recommends comparing premium, deductible, coverage and IDV together.

Deductibles and Third-Party Insurance

A deductible should not automatically be assumed to apply identically to every part of a motor insurance policy.

Motor insurance can include third-party liability coverage and own-damage coverage, depending on the policy structure.

Deductible provisions should therefore be checked against the specific section of the policy and the type of claim being made.

The policy schedule and wording are the appropriate documents for determining whether a particular deductible applies.

How to Check Your Deductible Before Buying a Policy

Before purchasing or renewing car insurance, check:

1. The compulsory deductible.
2. Whether a voluntary deductible has been selected.
3. The total deductible if both apply.
4. Whether the deductible applies per claim, event or according to another specified basis.
5. Whether additional excess provisions apply in particular circumstances.
6. The IDV.
7. Depreciation provisions.
8. Add-on coverage and exclusions.
9. NCB implications.
10. The claims procedure and documentation requirements.

The exact provisions should always be verified in the policy schedule and policy wording.

How to Choose an Appropriate Deductible

There is no single deductible that is suitable for every car owner.

A policyholder should consider how much of a repair bill they could comfortably pay from their own funds. Choosing a high voluntary deductible simply to reduce the premium can increase out-of-pocket costs when a claim occurs.

Conversely, a lower deductible may provide a smaller financial contribution at claim time but can involve a higher premium.

The important point is to compare the overall cost and coverage, rather than choosing a policy solely because it has the lowest premium.

Common Mistakes to Avoid

Car owners commonly make several mistakes when evaluating deductibles:

• Looking only at the annual premium
• Ignoring the policy schedule
• Assuming the insurer will pay the entire repair bill
• Confusing deductible with depreciation
• Not checking voluntary deductible selection
• Ignoring IDV and coverage differences
• Assuming every claim is subject to exactly the same treatment
• Failing to understand add-on conditions

Reading the policy wording before an accident occurs can make the claims process easier to understand.

Conclusion

Excess and deductible terms have a direct impact on how much a policyholder may need to pay when making an eligible car insurance claim. A compulsory deductible is generally required under the applicable policy terms, while a voluntary deductible is an additional amount selected by the policyholder and may reduce the premium.

A higher deductible can lower the upfront insurance cost, but it also increases the policyholder’s potential contribution during a claim. Therefore, car owners should compare the premium, deductible, IDV, coverage, exclusions and add-ons together.

Most importantly, the deductible should be considered as part of the overall insurance cost rather than as a minor detail. Understanding it before purchasing or renewing a policy can help prevent unexpected out-of-pocket expenses when a claim occurs.
