What Is No Claim Bonus (NCB)? Meaning, Benefits, Calculation & Rules

If you have been renewing your car insurance every year without making a claim, you may have noticed something called No Claim Bonus (NCB) on your policy. It is one of the easiest ways to reduce the cost of your car insurance renewal.

NCB is basically a reward for maintaining a claim-free insurance record. The longer you go without making an eligible own-damage claim, the higher your NCB can become, subject to the applicable rules and policy terms.

But many car owners are still confused about how NCB works, how much discount they can get, and what happens to it after making a claim.

Let's understand No Claim Bonus (NCB) in simple terms.

What Is No Claim Bonus (NCB)?

NCB stands for No Claim Bonus.

It is a discount offered on the Own Damage (OD) portion of a motor insurance premium when the insured does not make or have a pending eligible claim during the preceding policy period.

In the commonly used NCB structure, the discount increases with consecutive claim-free years and can reach up to 50%. The applicable NCB is generally considered at the time of policy renewal.

For example, if you complete a policy year without making a claim, you may become eligible for an NCB at renewal. If you continue having claim-free years, the percentage can increase.

So, in simple words:

No Claim = Reward

More Claim-Free Years = Higher Potential Discount

How Does NCB Work?

NCB is linked to your claim-free insurance history.

A commonly applicable NCB structure is:

These percentages apply to the eligible Own Damage premium, not necessarily to the entire amount you pay for your car insurance.

For example, suppose the Own Damage portion of your renewal premium is ₹10,000 and you are eligible for a 50% NCB.

Your NCB discount could be:

₹10,000 × 50% = ₹5,000

So the eligible Own Damage premium after the NCB discount would be ₹5,000, before considering other applicable components, taxes, deductibles, add-ons, or adjustments.

Is NCB Available on Third-Party Insurance?

No Claim Bonus is generally associated with the Own Damage component of motor insurance.

A standalone third-party policy does not provide an Own Damage section on which this discount can be applied.

Therefore, NCB is mainly relevant when you have an eligible Own Damage or comprehensive motor insurance policy.

Why Is NCB Important?

NCB can make a noticeable difference to your insurance renewal cost, especially after several claim-free years.

Some important benefits include:

1. Lower Insurance Renewal Cost

The biggest advantage is the potential reduction in the Own Damage premium.

2. Reward for Safe Ownership

NCB encourages vehicle owners to maintain their vehicles carefully and avoid unnecessary claims.

3. Can Become More Valuable Over Time

The discount can increase after consecutive claim-free years, subject to applicable terms.

4. Useful When Renewing Insurance

A good NCB record can help reduce the cost of your eligible insurance renewal.

What Happens to NCB After Making a Claim?

This is one of the most important things to understand.

If you make an eligible own-damage claim, your NCB can be affected at the next renewal. Depending on the applicable rules and policy conditions, the accumulated NCB may reduce or become zero.

For example, imagine you have built up a 50% NCB over several years. If you make a claim, you should not assume that the 50% discount will automatically remain unchanged at your next renewal.

The exact impact depends on the policy terms and any NCB protection add-on you may have purchased.

What Is NCB Protection?

Some insurance companies offer an optional NCB Protection add-on.

This cover is designed to protect your accumulated NCB under specified conditions even after certain claims.

However, NCB protection does not mean that every claim will automatically leave your NCB untouched. The number and type of claims covered, eligibility requirements, and conditions can vary between insurers.

Always read the policy wording before purchasing an NCB protection add-on.

Does NCB Belong to the Car or the Owner?

NCB is generally associated with the insured person's claim history, rather than simply being attached to the vehicle.

This becomes particularly important when you sell your car and purchase another one.

If you have built up an eligible NCB, you may be able to transfer the benefit to your new vehicle, subject to the insurer's process and applicable documentation.

So, selling your old car does not necessarily mean you have to lose your accumulated NCB.

Can NCB Be Transferred to a New Car?

Yes, subject to applicable insurer rules.

If you sell your existing car and buy another vehicle, you may be able to carry your eligible NCB forward to the new vehicle.

The insurer may ask for documents such as:

• Previous insurance policy

• NCB certificate or renewal documentation

• Proof of sale

• Vehicle transfer documents

• New vehicle details

The exact requirements can differ between insurers.

What Happens If You Change Your Insurance Company?

Changing your insurance company does not necessarily mean losing your NCB.

If you have earned an eligible NCB with your previous insurer, the benefit can generally be carried forward when you move to another insurer, subject to verification and applicable rules.

Your previous policy documents or proof of NCB may be required.

Always provide accurate information about your previous insurance history when purchasing a new policy.

Does NCB Apply to the Entire Insurance Premium?

No.

This is a common misunderstanding.

NCB is generally calculated on the Own Damage premium, rather than the entire insurance premium.

Your total insurance cost may also include components such as:

• Third-party premium

• Own Damage premium

• Add-ons

• Applicable taxes

• Other charges or adjustments

Therefore, a 50% NCB does not necessarily mean your total insurance bill will be reduced by 50%.

Should You Make a Small Insurance Claim?

This is something vehicle owners often think about.

Suppose your car has minor damage and the repair cost is relatively small. Before making a claim, you may want to compare the repair cost with the potential impact on your NCB.

For example, if a small repair costs ₹4,000 but losing a valuable NCB could result in a larger increase in your future insurance cost, paying for the repair yourself may sometimes make financial sense.

However, this is not a universal rule. Your decision should depend on the repair amount, policy terms, NCB value, deductibles, and your circumstances.

Common Mistakes to Avoid

When it comes to NCB, avoid these mistakes:

• Assuming NCB applies to the entire premium

• Forgetting to declare your previous NCB

• Assuming NCB automatically transfers to a buyer

• Making unnecessary claims for very small repairs

• Ignoring your policy renewal date

• Assuming NCB protection covers unlimited claims

• Providing incorrect claim history

• Losing previous insurance documents

Keeping your insurance records organized can make renewal and NCB transfer much easier.
