No-claim bonus, or NCB, is one of the most useful renewal benefits for careful car owners. It rewards you when you complete a policy year without making a claim. Many people know that NCB can reduce the renewal premium, but they may not know how the benefit is applied.
Understanding this clearly helps you make better decisions before raising claims or renewing your policy.
What NCB Means for Policyholders
NCB is a renewal benefit given to policyholders who do not make a claim during the policy period. It shows that the car owner has maintained a claim-free record, so the insurer offers a discount on the eligible premium at renewal.
This benefit is not paid in cash. It is adjusted in the renewal premium and usually applies to the own damage part of the policy. The higher your accumulated NCB, the more it may help reduce the eligible premium, subject to policy terms.
How Much Can NCB Reduce Your Premium?
NCB can reduce the own damage premium in car insurance based on your claim free years. The longer you avoid claims, the higher the discount may become, subject to policy terms.
| Claim Free Year | NCB Discount |
| After 1st claim free year | 20% |
| After 2 consecutive claim free years | 25% |
| After 3 consecutive claim free years | 35% |
| After 4 consecutive claim free years | 45% |
| After 5 consecutive claim free years | 50% |
These percentages are applied as per policy terms. The actual saving depends on the own damage premium, not the total policy premium.
How NCB Is Calculated
NCB is calculated on the own damage part of the premium. This is the portion that covers your car against insured risks such as accident, theft, fire or natural calamities, subject to policy terms. Other charges, add-ons, statutory components and third-party liability premium are calculated separately.
So, the final renewal amount may not be reduced by the same percentage as your NCB slab. A 50% NCB means the eligible own damage premium receives the applicable discount, not the full policy premium.
What Happens to NCB if You Make a Claim?
If you make a claim during the policy period, your NCB may be reduced or reset at renewal because it is given for claim-free years. Before raising a small claim, compare the repair cost with the NCB benefit you may lose.
Key points to remember:
- A claim may affect your NCB at renewal.
- Small repair claims should be compared with possible NCB loss.
- Genuine claims for major damage, theft, third-party involvement or safety-related repairs should not be avoided.
- An NCB protection add-on may help retain the benefit after a limited number of claims, subject to policy terms.
Why NCB Does Not Reduce the Entire Premium
NCB does not reduce the full policy premium. It usually applies only to the own damage premium, while third party liability premium, add-ons, taxes and other charges are calculated separately. This is why the final renewal saving may be lower than the NCB percentage shown.
Key points to remember:
- NCB applies to the own damage premium.
- It does not apply to the third party insurance premium.
- Add-ons, taxes and other charges may not receive the NCB discount.
- The final saving depends on how much of your total premium comes from the own damage component.
How to Check NCB during Renewal
Before paying the renewal premium, check these points:
- Your current NCB percentage
- Whether any claim was made in the last policy year
- Whether the policy is being renewed on time
- Whether NCB is applied only to the own damage part
- Whether any add-ons affect the final premium
- Whether the details match your previous policy record
This helps you avoid errors and understand the actual savings clearly.
Final Thoughts
NCB can reduce your renewal premium when you maintain a claim free record, but the saving applies only to the own damage part of the policy. It does not reduce third-party insurance premiums, add-ons, taxes or other charges.
This is why the final discount may look lower than the NCB percentage mentioned in the policy. To use this benefit properly, check your NCB percentage, renew on time, avoid unnecessary small claims and review the premium breakdown before making payment.
