No Claim Bonus Calculator: Complete Car & Bike NCB Guide
A **No Claim Bonus (NCB)** is one of the most rewarding features of comprehensive motor insurance in India. Established by the Insurance Regulatory and Development Authority of India (IRDAI), NCB is a discount earned on your **Own Damage (OD) premium** for every year you drive safely and do not file an insurance claim.
Accumulating an NCB discount can reduce your annual car or bike insurance renewal premium by up to **50%**. However, filing even a single small claim can instantly reset your accumulated NCB discount to **0%**, costing you thousands of rupees over the next five years. Our free online No Claim Bonus Calculator calculates your exact NCB discount slab, evaluates whether you should file a claim or pay out-of-pocket for minor repairs, and estimates your NCB Transfer Certificate savings when buying a new car.
IRDAI Official NCB Discount Slab Structure
The IRDAI mandates a standardized NCB discount slab progression across all general insurance companies in India:
| Consecutive Claim-Free Policy Years | IRDAI NCB Discount Percentage | Example Savings on ₹15,000 OD Premium |
|---|---|---|
| 0 Years (New Vehicle / Claim Filed) | 0% NCB Discount | ₹0 Saved (Full OD Premium ₹15,000) |
| 1st Consecutive Claim-Free Year | 20% NCB Discount | Save ₹3,000 (Pay ₹12,000) |
| 2nd Consecutive Claim-Free Year | 25% NCB Discount | Save ₹3,750 (Pay ₹11,250) |
| 3rd Consecutive Claim-Free Year | 35% NCB Discount | Save ₹5,250 (Pay ₹9,750) |

| 5th Consecutive Claim-Free Year (Max Cap) | 50% Maximum NCB Discount | Save ₹7,500 (Pay Only ₹7,500!) |
The Golden Rule: Claim vs Pay Out-of-Pocket Decision
When your car suffers a minor scratch, dent, or broken side mirror, your immediate reaction might be to file an insurance claim. However, doing so can be a costly financial mistake.
- Compulsory Deductible: Insurers automatically deduct a compulsory excess (typically ₹1,000 for cars, ₹100 for bikes) from every claim payout.
- NCB Reset Impact: Filing a claim resets your 50% NCB back to 0%. Over the next 5 years, you will lose **2.75 times your annual OD premium** in lost renewal discounts!
- The Financial Formula:
If (Repair Estimate - Compulsory Deductible) < Total 5-Year Lost NCB Savings → PAY OUT-OF-POCKET!

How to Transfer Your 50% NCB to a New Car
One of the best-kept secrets in motor insurance is that **No Claim Bonus belongs to the car owner, NOT the vehicle**.
- Selling Old Vehicle: When selling your old car, request an **NCB Transfer Certificate** from your insurance company.
- Buying New Vehicle: Submit the NCB Certificate to your new insurer when purchasing a new car.
- Massive Savings: The 50% NCB discount applies immediately to your new car's Own Damage premium, saving up to ₹20,000 to ₹35,000 in your first policy year!
What is an NCB Protection Cover Rider?
An **NCB Protection Cover** is an inexpensive add-on rider (costing ~5% to 10% of OD premium) that allows you to make 1 claim during the policy year without forfeiting your accumulated 20%-50% NCB discount slab.

Frequently Asked Questions (FAQs)
What is No Claim Bonus (NCB) in motor insurance?
No Claim Bonus (NCB) is a reward discount given by general insurance companies to vehicle owners for not making any insurance claims during the policy year. NCB discount ranges from 20% after 1 claim-free year up to a maximum of 50% after 5 consecutive claim-free years.
Does NCB apply to Third-Party Insurance or Own Damage Premium?
NCB discount applies exclusively to the Own Damage (OD) premium portion of comprehensive motor insurance policies. It does NOT apply to mandatory Third-Party (TP) insurance premiums mandated by IRDAI.
What happens to my NCB if I file a single insurance claim?
If you file even a single claim during the policy year, your accumulated NCB discount drops to 0% upon the next renewal, unless you have purchased an NCB Protection Cover add-on rider.
Can I transfer my 50% NCB when buying a new car or bike?
Yes! NCB belongs to the vehicle owner, NOT the vehicle. When selling your old vehicle, you can obtain an NCB Transfer Certificate from your insurer and apply your 50% NCB discount to the Own Damage premium of your new car or bike, saving thousands of rupees.
What is an NCB Protection Cover Rider?
An NCB Protection Cover is an add-on rider that allows you to make 1 (or sometimes 2) claims in a policy year without resetting your accumulated 20%-50% NCB discount slab back to 0%.
When should I pay for minor car repairs out of pocket instead of claiming?
If the cost of minor repair (e.g. ₹4,000 dent) is less than the total accumulated NCB discount savings you will lose over the next 5 years (plus compulsory deductible), it is financially wiser to pay out-of-pocket and preserve your 50% NCB.
