NCB - No Claim Bonus - is the most financially significant benefit available to disciplined two-wheeler owners in India, and yet it is also the most commonly misunderstood. At its maximum, NCB cuts your own-damage (OD) premium by 50%. That is a massive saving that compounds over years of careful riding. Here's how it works, how you accumulate it, and crucially - how you avoid losing it.
| Number of Consecutive Claim-Free Years | NCB Discount on OD Premium | Example: OD Premium ₹3,000 | Actual OD Premium After NCB |
|---|
| 1 year | 20% | ₹3,000 | ₹2,400 |
| 2 years | 25% | ₹3,000 | ₹2,250 |
| 3 years | 35% | ₹3,000 | ₹1,950 |
| 4 years | 45% | ₹3,000 | ₹1,650 |
| 5 years or more | 50% (MAX) | ₹3,000 | ₹1,500 |
Key NCB Rules Every Bike Owner Must Know
- NCB belongs to you, not the bike. When you sell your bike and buy a new one, you carry your NCB with you - within 90 days of the sale.
- NCB resets to zero on any claim. Even a single small claim wipes out all accumulated NCB - unless you have NCB Protection cover.
- NCB lapses if you don't renew within 90 days of your policy expiry date.
- NCB applies only to OD premium, not to the third-party component, which is IRDAI-regulated and fixed.
- You must obtain an NCB Retention Certificate from your current insurer when switching - insurers cannot verify NCB otherwise.
The critical calculation every bike owner should do before making a small claim: Is the claim amount worth more than the NCB you'll lose? If you have 5 years of NCB (50% discount) and your OD premium is ₹2,800, you're saving ₹2,800/year from NCB. A ₹4,000 repair claim might get you ₹2,000 after compulsory deductible and depreciation. But losing 50% NCB costs you ₹2,800 in the next year alone - and then you have to rebuild it from scratch. In almost all cases for small claims under ₹8,000–₹10,000, it is financially smarter not to claim and pay for the repair yourself.
NCB Protect Add-On: When It's Worth Buying
NCB Protection add-on allows you to make 1 (or in some policies, 2) claims in a policy year without losing your accumulated NCB. The add-on costs approximately ₹150–₹400/year depending on the insurer. If you have 3+ years of NCB (35% or higher discount), NCB Protection is almost always worth the additional premium - because a single claim can set you back 3 years of disciplined riding.
