When you are looking to save on your car insurance premiums, understanding your No Claim Bonus (NCB) can make a huge difference. NCB is the reward you earn for driving responsibly and not making any claims during your policy year.
Knowing how to calculate it helps you plan renewals better and make informed choices while buying or renewing your policy. By checking your accumulated bonus, you can see how much you are saving and how to keep that discount intact for years to come.
What is a No-Claim Bonus?
A No Claim Bonus is a discount offered by your car insurance provider on the own damage (OD) benefits of your premium for every claim-free year. It is an incentive to drive carefully and maintain your vehicle responsibly.
Here is how it works:
- You earn your first NCB after completing one claim-free year.
- The discount starts at 20% and increases with every consecutive claim-free year.
- You can accumulate up to 50% NCB after five continuous claim-free years.
You can easily check and manage your bonus when renewing or buying car insurance online, as most insurers display your NCB percentage in the premium breakdown.
NCB Calculation Table
Here is a year-wise table showing how NCB grows with each claim-free policy term:
| Claim-Free Years | NCB Percentage |
| 1 year | 20% |
| 2 years | 25% |
| 3 years | 35% |
| 4 years | 45% |
| 5 years | 50% |
How to Check and Transfer Your NCB?
If you are unsure of your NCB status, it is easy to find out:
- Check Your Renewal Notice or Policy Document: Your insurer lists your current NCB percentage in the renewal summary.
- Visit Your Insurer’s Online Portal: Most insurers allow you to log in and check your policy details, including your active NCB.
- Contact Customer Support: You can confirm your eligibility for renewal discounts before making payment.
When changing your car or insurer, you can transfer your accumulated bonus:
- Ask your previous insurer for an NCB certificate as proof of your earned bonus.
- Submit it to your new insurer when buying the next policy.
- The same bonus applies to your new policy, ensuring you do not lose your years of savings.
Tips to Maximise Your NCB
Keep your NCB intact and make the most of it with these simple practices:
- Avoid Small Claims: For minor dents or scratches, paying from your pocket may be more economical.
- Drive Responsibly: Fewer accidents mean uninterrupted NCB accumulation.
- Renew On Time: Delayed renewals can make your NCB lapse.
- Use Add-ons Wisely: You can buy the NCB Protection add-on when buying or renewing your policy to help preserve your bonus even after limited claims.
Conclusion
Knowing how to calculate your No Claim Bonus helps you make smarter financial decisions about your car insurance. Every claim-free year adds to your reward, lowering the premium you pay at renewal. Over time, these savings can be significant, especially if you maintain a clean driving record for several consecutive years.
A well-managed NCB does not just save money. It reflects consistent, responsible driving and good vehicle maintenance. It also gives you more flexibility when switching insurers or upgrading your car, as your earned bonus stays with you through the NCB certificate.
In today’s digital-first environment, keeping track of your policy and accumulated bonus is easier than ever. Leading insurers like TATA AIG offer user-friendly online tools that help you review your NCB status, renew your car insurance online and choose add-ons that help preserve your benefits.
