What Is NCB in Car Insurance? No Claim Bonus Explained
What Is NCB in Car Insurance? No Claim Bonus Explained
If you have renewed your car insurance without making a claim, you may have noticed a term called NCB on your policy. NCB can reduce the premium payable for eligible own-damage cover when you maintain a claim-free record, subject to the insurer's terms and applicable rules.
But how exactly does NCB work? What happens to it after a claim? Can you transfer it when you buy another car? And what happens when you change your insurance company?
This guide explains NCB in car insurance in simple language.
What Is NCB in Car Insurance?
NCB stands for No Claim Bonus.
It is a benefit generally provided to an eligible policyholder for a claim-free period. It is typically applied as a discount on the own-damage premium, subject to the applicable policy terms.
In simple terms:
No eligible claim → NCB may accumulate → eligible own-damage premium can receive an NCB discount at renewal.
NCB is therefore different from the total insurance coverage or IDV of your vehicle.
How Does No Claim Bonus Work?
Suppose you have a car insurance policy and complete the policy period without making a claim that affects your NCB.
At renewal, you may become eligible for an NCB benefit according to the insurer's applicable rules.
If you continue to have eligible claim-free periods, the NCB may increase until it reaches the maximum permitted under the applicable rules.
The exact percentage and conditions should always be checked in your current policy documents or renewal quotation.
Is NCB a Discount on the Entire Car Insurance Premium?
Usually, NCB is associated with the own-damage component rather than the entire insurance premium.
This distinction is important.
A motor insurance premium can contain different components, including:
- Third-party liability premium
- Own-damage premium
- Add-on premiums
- Applicable taxes and other charges
Therefore, if you see an NCB discount, don't assume that the same percentage is deducted from the entire amount you pay.
Simple NCB Example
Suppose your eligible own-damage premium before NCB is:
₹10,000
If the applicable NCB is 20%, the NCB discount would be:
₹2,000
The remaining own-damage premium would therefore be:
₹8,000
Other applicable premiums, add-ons, taxes and charges can change the final amount payable.
This is only an illustration. The actual NCB percentage and premium calculation depend on the applicable policy and insurer.
Does NCB Increase Every Claim-Free Year?
NCB can increase after successive eligible claim-free periods, subject to the applicable rules and maximum limit.
However, you should not assume that the NCB automatically increases in every situation.
The applicable policy conditions determine:
- Whether you qualify
- The NCB percentage
- The maximum NCB
- Whether a claim affects the accumulated NCB
- Whether an NCB protection benefit applies
Always check the renewal quotation and policy schedule.
What Happens to NCB After a Car Insurance Claim?
This is one of the most important questions about NCB.
A claim can affect your NCB entitlement at the next renewal, depending on the policy terms.
For example, if you have accumulated an NCB through claim-free years and subsequently make an eligible claim, the NCB may be reduced or lost at renewal according to the applicable rules.
The exact effect depends on:
- Type of claim
- Policy terms
- Insurer
- Whether an NCB protection add-on was purchased
- Applicable conditions
This is why understanding NCB is particularly useful before making a claim for relatively minor damage.

Should You Avoid Making a Claim to Protect NCB?
Not necessarily.
NCB is only one factor to consider.
If your vehicle has suffered substantial damage or you have a covered loss, the potential insurance benefit may be much more important than preserving an NCB discount.
For a minor repair, however, you can compare:
- Estimated repair cost
- Deductible
- Potential claim amount
- Possible effect on NCB
- Policy conditions
Don't avoid a legitimate claim solely because of NCB without considering the actual financial impact.
What Is NCB Protection?
Some motor insurance policies may offer an NCB Protection or similar add-on.
The purpose of such an add-on is generally to protect the policyholder's accumulated NCB under specified circumstances, even after a permitted number or type of claims.
The exact protection varies between insurers and products.
Before purchasing the add-on, check:
- Number of claims permitted
- Type of claims covered
- Conditions for retaining NCB
- Additional premium
- Exclusions
- Maximum NCB protected
Don't assume that NCB protection means your NCB is protected from every possible claim.
Is NCB Protection Worth Considering?
There is no universal answer.
Compare the additional cost of the add-on with the NCB benefit you are trying to protect.
It may be particularly relevant for someone who has accumulated a significant NCB and wants additional protection against losing that benefit, but the suitability depends on the policy terms and individual circumstances.
Read the actual add-on wording before purchasing it.
Can NCB Be Transferred to a New Car?
In many cases, an eligible policyholder can carry forward their accumulated NCB when replacing a vehicle, subject to applicable insurer requirements and conditions.
This is important because NCB is generally associated with the policyholder's claim-free record, rather than simply being permanently attached to one specific car.
However, the transfer process and eligibility requirements should be confirmed with the insurer.
Can NCB Be Transferred When Changing Insurance Companies?
An eligible NCB can generally be recognised when changing insurers, subject to verification and the applicable rules.
When switching insurers, provide the required evidence of your existing NCB.
The new insurer may verify your previous policy and claim history.
Do not simply enter an NCB percentage without being able to substantiate it when required.
What Is an NCB Certificate?
An NCB certificate or equivalent evidence can be used to establish the policyholder's accumulated NCB.
Depending on the insurer and process, documentation may include:
- Previous policy documents
- Renewal documents
- NCB confirmation
- Claim history information
- Other evidence requested by the insurer
Keep your previous policy documents when changing insurers or vehicles.
What Happens to NCB When You Sell Your Car?
Selling your car does not necessarily mean that your accumulated NCB has to disappear.
Eligible NCB may be retained or transferred according to the applicable rules, provided the required conditions are satisfied.
Contact your insurer when selling your vehicle and ask about the process for preserving your NCB.
Do not cancel or close your existing policy without understanding how your NCB will be handled.
Is NCB the Same as a No-Claim Record?
They are related but not exactly the same.
A claim-free record refers to the history of not making applicable claims during the relevant period.
NCB is the resulting insurance benefit that may be available because of that claim-free history.
The benefit is governed by the applicable policy rules.
Does NCB Affect Third-Party Insurance?
NCB is generally associated with the own-damage portion of motor insurance rather than the third-party liability premium.
This is why NCB is particularly relevant when discussing comprehensive or own-damage policies.
If you only have third-party liability insurance, the concept of an own-damage NCB discount generally does not work in the same way.

NCB and IDV Are Different
NCB and IDV are two completely different concepts.
NCB: A benefit related to eligible claim-free history.
IDV: The Insured Declared Value of the vehicle for applicable insurance purposes.
For example, a car can have:
- A particular IDV
- A particular NCB percentage
- A particular deductible
All three affect different parts of the insurance policy.

Common NCB Mistakes
Entering the Wrong NCB
Don't claim an NCB percentage simply because you think you are entitled to it.
Check your previous policy or insurer's records.
Forgetting About a Previous Claim
Claims can affect NCB eligibility.
Provide accurate information when purchasing or renewing insurance.
Assuming NCB Applies to the Entire Premium
NCB is generally associated with the eligible own-damage component.
Ignoring the Policy Expiry
NCB continuity can depend on renewal timing and applicable conditions.
Assuming Every Insurer Has Identical Rules
Check the actual policy terms instead of relying on a generic online percentage.
How to Check Your NCB Before Renewal
Before renewing your policy:
- Open your previous insurance policy.
- Look for the NCB information.
- Check whether you made any claims.
- Check the NCB shown in the renewal quotation.
- Compare it with your previous policy.
- Contact the insurer if the information appears incorrect.
This simple check can help prevent errors during renewal.
NCB When Switching Insurers
Changing insurers does not necessarily mean losing your accumulated NCB.
Before purchasing the new policy:
- Check your existing NCB.
- Keep your previous policy document.
- Provide accurate details to the new insurer.
- Submit any requested proof.
- Check that the NCB appears correctly in the new policy.
Never intentionally provide incorrect claim-history information to obtain a larger discount.
