How is no claim bonus calculated in car insurance?

Car insurance is mandatory in India, and your premium depends on multiple factors such as the vehicle’s IDV, registration location, and claim history. One of the most effective ways to bring down the annual premium is through the No Claim Bonus (NCB), a discount that insurers offer when you complete a policy year without filing any claims. The discount applies only to the own-damage portion of the premium and grows each year you remain claim-free, reaching up to 50% after five consecutive years. Knowing how NCB is calculated and retained can result in meaningful savings over the life of your vehicle.

What is No Claim Bonus?

No Claim Bonus (NCB) is a discount or rebate offered by car insurance companies on the Own Damage premium portion when no claims are made during the policy year. It serves as a reward for claim-free driving, promoting safer and responsible vehicle usage.

For example, if you do not make any claims in your first year, you are entitled to a 20% NCB discount on your next year's own damage premium (excluding third-party car insurance premium and taxes). In subsequent claim-free years, this discount increases by about 5% annually, reaching up to 50% by the sixth year. This tiered discount incentivizes continuous claim-free driving and careful vehicle maintenance.

How to Calculate No Claim Bonus in Car Insurance?

The No Claim Bonus calculation starts from your second policy year onwards, based on consecutive claim-free years. The NCB applies only to the Own Damage premium, the part of your premium covering damage to your car, and not the third-party liability premium.

 The NCB discount rates typically follow this pattern as per industry standards and IRDAI guidelines:

Example: If your total car insurance premium is ₹10,000 with an Own Damage premium portion of ₹7,000, and you qualify for a 20% NCB after a claim-free first year, your payable own damage premium reduces by 20% of ₹7,000 = ₹1,400. Thus, your revised premium will be ₹10,000 - ₹1,400 = ₹8,600 plus applicable taxes.

This means your NCB discount directly lowers only the Own Damage premium, but overall reduces your total premium cost.

Benefits of NCB in car insurance 

NCB offers several practical advantages beyond just a lower premium number.

• Discount on premium: The most direct benefit is a percentage reduction on the own-damage premium at renewal. This is applied automatically when the insurer confirms your claim-free status for the previous year.
  

• Higher savings over time: If you continue without making claims, the NCB grows from 20% to 50% over five years. On a car with an own-damage premium of ₹15,000, a 50% NCB saves you ₹7,500 every year, which adds up significantly over the vehicle’s lifespan.
  

• Transferable between vehicles and insurers: NCB is linked to the policyholder, not the car. If you sell your car and buy a new one, or switch to a different insurer, you can carry forward the accumulated NCB by providing the required documentation.
  

• Encourages safe driving: Since making a claim reduces or removes the NCB, it motivates drivers to drive carefully and avoid filing claims for minor damage that can be repaired out of pocket.
  

• Long-term cost advantage: Maintaining NCB over multiple years makes comprehensive car insurance increasingly affordable, especially as the car ages and the IDV drops simultaneously.
  

• NCB protection add-on available: Some insurers offer an add-on that lets you make a limited number of claims (usually one or two) during the year without losing your accumulated NCB, providing an extra layer of financial security.

Important terms and conditions of No Claim Bonus

To retain and maximise your NCB benefit, keep the following conditions in mind.

• NCB applies only to own-damage policies: It is not available on standalone third-party policies. You must have a comprehensive or own-damage cover to earn and use NCB.
  

• Any claim during the policy year resets NCB: If you file even a single claim, the accumulated NCB is cancelled, and you have to start building it again from zero in the next claim-free year. The only exception is if you have an active NCB protection add-on.
  

• Renew within 90 days of expiry: If your policy lapses and you do not renew within 90 days after the expiry date, your NCB entitlement resets to zero. Timely renewal is essential to preserve the discount.
  

• NCB is transferable with documentation: You can transfer NCB to a new car or a different insurer during the renewal period. The previous insurer issues an NCB certificate, which the new insurer verifies before applying the discount. Acceptance is subject to the new insurer’s terms.
  

• NCB is tied to the policyholder, not the vehicle: This means if you sell your car, the NCB stays with you and can be applied to the insurance policy of your next vehicle.
  

• Incorrect NCB declaration can attract penalties: Insurers verify NCB certificates during underwriting. If discrepancies are found between your declared NCB and the actual records, the insurer may ask for premium adjustments or reject the claim.

How the No-Claims Bonus  discount works?

Here are the key points to understand how the No-Claims Bonus reduces your car insurance premium over time:

1. Earned for Claim-Free Years If you don’t make any claim during a policy year, you earn an NCB at the time of renewal. This discount increases with every consecutive claim-free year.

2. Discount on Own Damage Premium: NCB is applied only to the own damage component of your car insurance premium—not on the third-party liability portion.

3. Progressive Increase in Discount: The NCB typically grows step-by-step as follows:

• 1st claim-free year: 20% discount

• 2nd year: 25%

• 3rd year: 35%

• 4th year: 45%

• 5th year: 50% (maximum)

4. Reset on Claim If you make even a single claim during the policy period, your accumulated NCB usually drops to zero at renewal.

5. Transferable Benefit NCB is linked to the policyholder, not the vehicle. So, if you sell your car and buy a new one, you can transfer your NCB to the new policy.

6. Protection Add-On (Optional) Some insurers offer an NCB protection add-on, allowing you to make a limited number of claims without losing your accumulated bonus.

Things to remember about No-Claim Bonus (NCB)

A No-Claim Bonus (NCB) is a reward given by insurers for not making any claims during a policy year. While it helps reduce your premium significantly, there are a few important points you should keep in mind:

1. NCB is linked to you, not your vehicle

NCB is tied to the policyholder, not the car. If you sell your car or buy a new one, you can transfer the NCB to your new vehicle.

2. It increases every claim-free year

With each consecutive year of no claims, your NCB percentage increases (usually up to 50%). The longer you avoid claims, the higher your discount on premiums.

3. It gets reset after a claim

If you make even a single claim during the policy period, your accumulated NCB typically drops to zero at renewal, unless you have NCB protection.

4. NCB protection add-on helps

By opting for an NCB protection add-on, you can retain your bonus even after making a limited number of claims in a year.

5. Timely renewal is crucial

If you fail to renew your policy within the grace period (usually 90 days), you may lose your accumulated NCB.

6. Applicable only on own-damage premium

NCB discount is applied only to the own-damage component of your car insurance premium—not on third-party liability coverage.

7. Transfer requires proof

To transfer your NCB to a new insurer or vehicle, you need to provide an NCB certificate from your previous insurer.

8. Avoid small claims

It’s often better to pay for minor repairs out of pocket instead of raising a claim, so you can preserve your NCB and enjoy higher discounts in the long run.

What is an NCB protector in car insurance?

The NCB protector is an add-on cover that safeguards your accumulated NCB even if you make a claim during the policy period. Under a standard policy, raising even a single claim resets the NCB to zero at renewal. The NCB protector removes this risk by allowing you to file a specified number of claims (usually one or two per year, depending on the insurer) without any impact on your NCB percentage.

This add-on is particularly valuable for policyholders who have built up a high NCB over several years and do not want a single unforeseen incident to wipe out their discount. The cost of the add-on is a small percentage of the base premium, but the savings from preserving a 45% or 50% NCB far outweigh the additional expense. It is a practical addition to any comprehensive car insurance policy, especially for drivers who commute in heavy traffic or park in areas prone to minor damage.

How does claim, policy lapse, or vehicle theft affect NCB?

Here’s how different situations can impact your accumulated No-Claims Bonus and future premiums:

• Claim impact: If you make a claim during the policy year, your NCB is usually cancelled or reduced. If you have NCB protection, this impact may be mitigated.
  

• Policy lapse: Failure to renew your policy within the 90-day grace period after expiry leads to loss of NCB.
  

• Vehicle theft or total loss: NCB may be forfeited if the vehicle is stolen or declared a total loss, as insurers cannot recover costs from third parties.

Documents required for NCB transfer

When transferring NCB to a new insurer or a new vehicle, you typically need to provide the following documents.

• Valid NCB certificate from your previous insurer, confirming the claim-free record and the NCB percentage earned.

• Copy of the previous insurance policy showing comprehensive or own-damage car insurance coverage and the NCB applied.

• Vehicle Registration Certificate (RC) of the new car if you are transferring NCB to a different vehicle.

• Proof of ownership transfer (Form 29 and Form 30) if the previous vehicle was sold.

• New vehicle insurance policy documents from the new insurer, if applicable.

Always confirm the specific documentation requirements with your new insurer before initiating the transfer to avoid delays in applying the NCB discount.

Other factors affecting car insurance premiums

Beyond NCB, several other factors determine the premium you pay for car insurance each year.

• Insured Declared Value (IDV). The current market value of the car after depreciation directly impacts the own-damage premium. A newer car with a higher IDV costs more to insure.

• Vehicle age and location. Older vehicles have lower IDVs but may carry higher repair risks. Cars registered in metro cities attract higher premiums due to traffic density and theft rates.

• Engine capacity (CC). The IRDAI fixes third-party car insurance premium rates in slabs based on cubic capacity. Cars with engines above 1500cc fall into the highest premium bracket.

• Driver age and experience. Some insurers factor in the primary driver’s age and driving record during underwriting. Younger or less experienced drivers may face marginally higher premiums.

• Type of cover. Comprehensive policies cost more than standalone own-damage or third-party policies because they combine both types of coverage.

• Add-ons selected. Optional covers like zero depreciation, engine protection, roadside assistance, and return to invoice increase the base premium but extend coverage for specific risks.

• GST at 18%. Applied on the total premium amount including add-ons and fees. This is a mandatory charge that adds to the final cost.

Understanding these factors alongside NCB helps you plan your car insurance purchase and renewal more effectively, balancing cost with adequate coverage.

Conclusion

No Claim Bonus in car insurance is a valuable discount that rewards claim-free driving with progressive savings on the own-damage premium. Starting at 20% after the first claim-free year and reaching 50% after five consecutive years, NCB can significantly reduce your annual insurance cost over time. The discount is tied to the policyholder and can be transferred when buying a new car or switching insurers, provided the transfer is completed within the renewal window with proper documentation. Filing a claim resets the NCB, but the NCB protection add-on offers a way to preserve the discount even after one or two claims. Renewing your policy on time, avoiding unnecessary small claims, and understanding the terms and conditions around NCB are simple steps that help you maximise this benefit.
