What Is No Claim Bonus (NCB) in Motor Insurance?

If you have held a motor insurance policy for more than a year without making a claim, your insurer owes you something. Not literally, but in the form of a discount on your next renewal premium. This is the No Claim Bonus, commonly referred to as NCB, and it is one of the most financially valuable features in motor insurance that a surprisingly large number of vehicle owners either do not know about or do not understand well enough to use properly.

The concept is straightforward. Drive carefully, avoid accidents, do not file claims, and your insurer rewards you with a progressively larger discount on the own damage component of your premium every year. Stay claim-free long enough and that discount can reach 50%, cutting nearly half your premium cost simply through careful driving and informed decision-making.

This guide explains exactly how NCB works, how it accumulates, what can reduce or eliminate it, and the strategies that help you protect and maximise it over time.

What Exactly Is No Claim Bonus?

No Claim Bonus is a discount offered by motor insurers on the own damage (OD) premium component of your policy at the time of renewal, as a reward for not making any claims during the previous policy year.

A few important clarifications upfront:

• NCB applies only to the own damage portion of your premium, not to the third-party liability premium, which is regulated by IRDAI and fixed regardless of your claim history
• NCB belongs to the policyholder, the vehicle owner, not to the vehicle itself. If you sell your car and buy a new one, your accumulated NCB travels with you
• NCB is not transferable between different policyholders. If you sell your car, the buyer does not inherit your NCB
• NCB is valid across insurers. If you switch insurance companies at renewal, your accumulated NCB must be honoured by the new insurer upon verification

How NCB Accumulates Over Time

The discount structure for NCB in India is standardised by the Insurance Regulatory and Development Authority of India (IRDAI). It works on a slab system based on consecutive claim-free years:

• After 1 claim-free year: 20% discount on OD premium
• After 2 consecutive claim-free years: 25% discount
• After 3 consecutive claim-free years: 35% discount
• After 4 consecutive claim-free years: 45% discount
• After 5 or more consecutive claim-free years: 50% discount

The progression is cumulative and consecutive. Every year you go without a claim, the discount increases. Miss a year, either by making a claim or by letting the policy lapse for more than 90 days and the NCB resets to zero.

At the 50% level, the financial impact is significant. If your own damage premium is ₹12,000 annually, an NCB of 50% saves you ₹6,000 every year. Over several years, this compounds into a substantial total saving.

A Practical Example of NCB in Action

Consider Ramesh, who buys a new car in 2019 and takes a comprehensive motor insurance policy. His own damage premium is ₹10,000 per year.

• 2019-2020: No claims filed. At renewal, he receives 20% NCB. OD premium becomes ₹8,000.
• 2020-2021: No claims filed. NCB increases to 25%. OD premium becomes ₹7,500.
• 2021-2022: No claims filed. NCB increases to 35%. OD premium becomes ₹6,500.
• 2022-2023: No claims filed. NCB increases to 45%. OD premium becomes ₹5,500.
• 2023-2024: No claims filed. NCB reaches the maximum of 50%. OD premium becomes ₹5,000.

By year five, Ramesh is paying half the own damage premium he started with. And as long as he continues to avoid claims, the 50% discount is maintained indefinitely at renewal.

Now consider what happens if in 2021-2022 Ramesh files a claim for minor accident damage. His NCB resets to zero. At the next renewal, he pays the full ₹10,000 OD premium again and must rebuild from scratch.

What Causes NCB to Reset to Zero

NCB is lost entirely in the following situations:

• Filing any own damage claim during the policy year, regardless of the claim amount
• Letting the policy lapse for more than 90 days without renewal. If the gap between expiry and renewal exceeds 90 days, the insurer is not obligated to honour the accumulated NCB
• Selling the vehicle without transferring the NCB to a new vehicle purchase. If you sell your car and do not buy another within a reasonable timeframe, the NCB may not be retained

One claim, even for a relatively minor repair, resets five years of accumulated discount instantly. This is why the decision of whether to claim or pay for repairs out of pocket is worth thinking through carefully each time.

The Critical Decision: Should You Claim or Pay Out of Pocket?

This is one of the most practically important questions in motor insurance, and the answer is not always obvious.

The general principle is: if the cost of repair is significantly lower than the NCB benefit you stand to lose by claiming, pay for the repair yourself.

Here is how to think through it. Suppose your OD premium is ₹12,000 and you have accumulated 35% NCB, saving ₹4,200 per year. You have a minor accident causing ₹8,000 worth of damage. If you claim:

• The ₹8,000 repair is covered
• Your NCB resets to zero
• Next year you pay the full ₹12,000 OD premium instead of ₹7,800
• That is an immediate annual loss of ₹4,200 in discount and you rebuild from zero again

In this scenario, paying the ₹8,000 yourself preserves ₹4,200 in annual savings going forward. Whether that trade-off makes sense depends on your specific numbers but the calculation is worth doing every single time before filing a claim.

For large claims, a major accident, a total loss, a theft, claiming is almost always the right decision regardless of NCB impact. The policy exists precisely for those situations.

NCB Belongs to You, Not Your Vehicle

This is one of the most misunderstood aspects of No Claim Bonus, and it has significant practical implications.

When you sell your vehicle, the NCB does not transfer to the buyer. It remains with you. What you can do is obtain an NCB retention letter or NCB certificate from your insurer at the time of vehicle sale. This document confirms your accumulated NCB percentage and allows you to apply it to the insurance policy for your next vehicle, as long as you purchase that vehicle within 3 years.

This means years of careful driving and disciplined claim behaviour follow you through vehicle changes. Selling a car does not mean starting from zero on your next one, provided you obtain and present the relevant documentation.

When buying a used car, do not assume you inherit the previous owner's NCB. You do not. The new policy for the vehicle starts fresh for you as the new owner.

Transferring NCB When Switching Insurers

Many vehicle owners worry that switching to a different insurance company at renewal means losing their NCB. This is not the case.

NCB is portable across insurers. When switching, you need to:

• Request an NCB certificate from your current insurer before the policy expires
• Submit this certificate to the new insurer at the time of policy issuance
• The new insurer is required by IRDAI regulations to honour the NCB percentage confirmed in the certificate

Do not let concerns about losing NCB keep you in a policy with an insurer whose service or pricing is no longer competitive. The discount travels with you.

NCB Protect Add-On: Is It Worth It?

Recognising that a single claim can wipe out years of accumulated discount, insurers offer an add-on cover called NCB Protect or NCB Protector. For an additional premium, this add-on allows you to make one, sometimes two, own damage claims in a policy year without losing your accumulated NCB.

Whether it is worth purchasing depends on a few factors:

• The additional premium charged for the add-on
• Your current NCB percentage, the higher it is, the more valuable protection becomes
• Your driving environment and risk exposure

At 40% or 50% NCB, the add-on is typically worth serious consideration. At 20%, the maths may not always support it. Compare the cost of the add-on against the annual saving your current NCB provides and make the decision accordingly.

NCB Protect add-ons also come with conditions, usually they only protect against claims where you are not at fault, or limit protection to one claim per year. Read the specific terms of the add-on before purchasing.

Common Misconceptions About NCB

1. "NCB applies to third-party premium too."

It does not. NCB applies only to the own damage component. Third-party liability premium is fixed by IRDAI and unaffected by your claim history.

2. "If I don't renew on time, I keep my NCB."

Only if the gap between expiry and renewal is 90 days or less. Beyond 90 days, the NCB is forfeited. Timely renewal is essential to preserving accumulated discount.

3. "NCB transfers to the buyer when I sell my car."

It does not. NCB stays with the policyholder, not the vehicle. The buyer starts afresh.

4. "Filing a third-party claim affects my NCB."

It does not. NCB is only affected by own damage claims. If someone else hits your car and you file a third-party claim against their insurance or if you file a claim under the third-party section of your own policy, your NCB is unaffected.

Conclusion

No Claim Bonus is one of the few features in motor insurance where responsible behaviour is directly and meaningfully rewarded. The discount structure is transparent, the rules are standardised, and the potential saving over time is genuinely significant.

Understanding how NCB accumulates, what protects it, when claiming is worth the cost, and how to carry it through vehicle changes and insurer switches gives you a real financial advantage as a vehicle owner. Most people leave money on the table simply through not knowing how the system works.

Frequently Asked Questions

Q1. Does NCB apply to two-wheelers as well as four-wheelers?

Yes. The NCB structure and slab rates are the same for both two-wheelers and four-wheelers. The same rules regarding accumulation, reset, portability, and documentation apply across vehicle types.

Q2. Can I claim NCB if I switch from a comprehensive policy to a standalone own damage policy?

Yes. NCB is applicable to the own damage component regardless of whether your policy is comprehensive or a standalone OD policy. The accumulated percentage remains valid upon renewal.

Q3. What happens to NCB if my car is stolen?

If your vehicle is stolen and a total loss claim is filed, your NCB resets to zero. However, if you purchase a new vehicle, you can request that your insurer consider your claim history favourably, though this is at the insurer's discretion rather than a standard entitlement.

Q4. How do I prove my NCB when switching insurers?

Request an NCB certificate from your current insurer before the policy expires. This document confirms your accumulated NCB percentage and is submitted to the new insurer at the time of fresh policy issuance.

Q5. Is there a maximum limit to NCB?

Yes. The maximum NCB permissible under IRDAI regulations is 50%, achieved after five or more consecutive claim-free years. It does not increase beyond 50% regardless of how many additional claim-free years follow.

Q6. What if I made a claim but the claim was later withdrawn?

If a claim is intimated but subsequently withdrawn before any payment is made, many insurers will not penalise the NCB but this varies by insurer and the specific circumstances. Always confirm with your insurer before withdrawing a claim, and get the confirmation in writing.

Q7. Can NCB be transferred to a family member's policy?

No. NCB is strictly linked to the individual policyholder and cannot be transferred to another person's policy, even within the same family.
