NCB Calculation & Transfer Rules
Definition
No Claim Bonus (NCB) is a reward given by insurers to policyholders who do not make any claim during a policy year. It is a cumulative discount applied to the Own Damage (OD) premium upon renewal. NCB increases progressively for each consecutive claim-free year: 20% after the 1st year, 25% after the 2nd year, 35% after the 3rd year, 45% after the 4th year, and 50% from the 5th year onwards. NCB belongs to the policyholder (not the vehicle) and can be transferred to a new vehicle.
Explanation in Simple Language
NCB is one of the most important features of motor insurance that directly impacts the premium. Key rules:
1. NCB is earned on the OD portion only — it does not apply to TP premium.
2. NCB accumulates year-on-year if no claim is made. After 5 consecutive claim-free years, the maximum NCB of 50% is reached.
3. If a claim is made during a policy year, the NCB resets to 0% at the next renewal.
4. NCB belongs to the policyholder, not the vehicle. If you sell your car and buy a new one, you can transfer your NCB to the new car's policy.
5. NCB can be transferred between insurers. If you switch from Insurer A to Insurer B, you carry your NCB with proof (previous policy copy showing NCB %).
6. NCB lapses if the policy is not renewed within 90 days of expiry. After 90 days, you lose the accumulated NCB.
7. NCB Protect add-on: This add-on preserves your NCB even if you make one claim during the year. It is available from most insurers for an additional premium.
Real-Life Indian Example
Meera has been insuring her Maruti Dzire for 5 years without making a single claim. Her NCB progression: Year 1 renewal: 20%, Year 2: 25%, Year 3: 35%, Year 4: 45%, Year 5: 50%. In the 5th year renewal, her OD premium (before NCB) was ₹8,500. With 50% NCB, she paid only ₹4,250 for OD. In the 6th year, she had a minor accident and claimed ₹15,000. At the next renewal, her NCB reset to 0%, and her OD premium jumped back to ₹8,800. She lost ₹4,400 in NCB discount for a ₹15,000 claim. Had she paid ₹15,000 out of pocket, she would have saved the NCB. Meera now buys NCB Protect add-on at ₹600/year.
Numerical Example
NCB Impact Calculation:
Vehicle: Honda City ZX (IDV: ₹7,50,000)
Base OD Premium: ₹15,000
Year 1 (Fresh policy): NCB = 0%, OD Premium = ₹15,000
Year 2 (No claim): NCB = 20%, OD Premium = ₹15,000 × 0.80 = ₹12,000
Year 3 (No claim): NCB = 25%, OD Premium = ₹15,000 × 0.75 = ₹11,250
Year 4 (No claim): NCB = 35%, OD Premium = ₹15,000 × 0.65 = ₹9,750
Year 5 (No claim): NCB = 45%, OD Premium = ₹15,000 × 0.55 = ₹8,250
Year 6 (No claim): NCB = 50%, OD Premium = ₹15,000 × 0.50 = ₹7,500
Total OD Premium Savings (Years 2-6): ₹15,000 × 5 - (₹12,000 + ₹11,250 + ₹9,750 + ₹8,250 + ₹7,500) = ₹75,000 - ₹48,750 = ₹26,250
If a claim is made in Year 6, NCB resets to 0% in Year 7.
Year 7 OD Premium = ₹15,000 (full price)
Loss of NCB = ₹7,500 per year until NCB rebuilds.
Policy Clause Reference
IRDAI Guidelines on NCB:
1. NCB Scale: 20% (1 year), 25% (2 years), 35% (3 years), 45% (4 years), 50% (5+ years) — as per IRDAI Motor Insurance guidelines.
2. Transfer of NCB: NCB is admissible to the insured and can be transferred from one vehicle to another owned by the same person, or to a new insurer. Proof of NCB (previous policy copy or NCB certificate) is mandatory.
3. Grace Period: NCB is preserved if the policy is renewed within 90 days of expiry. Beyond 90 days, NCB lapses.
4. NCB in case of Total Loss/Theft: If a vehicle is stolen or totally lost and the claim is settled, the NCB is not applicable for that year. However, the insured can start fresh NCB accumulation on a new vehicle.
5. NCB Protect Add-on: Available at additional premium, it allows the insured to make one claim without losing NCB.

Claim Scenario
Scenario: Suresh has 50% NCB on his Toyota Innova policy. His son borrows the car and reverses into a compound wall, causing ₹12,000 damage to the rear bumper. Suresh considers whether to claim or pay out of pocket.
Analysis:
- Current OD Premium: ₹18,000 (after 50% NCB on base ₹36,000)
- If claim is made: NCB resets to 0% next year. Next year OD Premium = ₹36,000
- Premium increase next year: ₹36,000 - ₹18,000 = ₹18,000
- It will take 5 years to rebuild 50% NCB, losing approximately ₹54,000 in total discounts
- Claim amount: ₹12,000 (minus ₹1,000 deductible = ₹11,000 net)
Decision: Suresh wisely chose to pay ₹12,000 out of pocket and preserved his 50% NCB, saving approximately ₹54,000 over the next 5 years.
Common Rejection Reason
1. NCB Claimed Without Proof — The policyholder claims NCB from a previous insurer but cannot produce the old policy copy or NCB confirmation letter.
2. NCB on Expired Policy — The previous policy expired more than 90 days ago, so NCB has lapsed, but the policyholder still claims it.
3. NCB Transfer to Wrong Person — NCB belongs to the policyholder, not the vehicle. If a car is sold, the buyer cannot claim the seller's NCB.
4. Duplicate NCB — Some policyholders try to claim NCB on two vehicles simultaneously. NCB can only be applied to one vehicle at a time.
5. NCB After Claim — The policyholder made a claim in the previous year but did not inform the new insurer, claiming NCB they are not entitled to.
Legal / Arbitration Angle
NCB disputes are common in insurance litigation. The key principle is that NCB belongs to the insured person, not the vehicle or the insurer.
In Kokila Devi v. United India Insurance (Consumer Forum, Chandigarh, 2019), the forum ruled that when a policyholder transfers to a new insurer and provides proof of NCB from the previous insurer, the new insurer cannot refuse to grant NCB merely because the previous insurer did not respond to their verification request. The burden of verifying NCB is on the insurer, not the policyholder.
The Insurance Ombudsman has consistently held that NCB cannot be denied at the time of claim settlement if it was accepted at the time of policy issuance and premium was charged accordingly. If the insurer accepted a lower premium with NCB, it is estopped from denying NCB during claims.
Court Case Reference
Key Case: Laxmi Devi v. IFFCO Tokio General Insurance (State Consumer Commission, Rajasthan, 2020) — The court held that once NCB is reflected in the policy schedule and premium is charged accordingly, the insurer cannot retrospectively withdraw NCB at the time of claim. The insurer's failure to verify NCB at issuance cannot prejudice the policyholder.
Common Sales Mistakes
1. Not explaining the financial value of NCB in rupee terms — customers need to see the actual savings.
2. Failing to remind customers about the 90-day renewal deadline.
3. Not recommending NCB Protect add-on, especially for customers with high NCB (45-50%).
4. Incorrectly telling customers that NCB stays with the vehicle — it belongs to the person.
5. Not collecting previous policy copy or NCB certificate when processing a transfer from another insurer.
Claims Dispute Example
Dispute: Kavita switched her car insurance from ICICI Lombard to HDFC ERGO, carrying 45% NCB. HDFC ERGO issued the policy with 45% NCB discount. Two months later, she had an accident and claimed ₹85,000. At settlement, HDFC ERGO reduced the claim by the NCB amount, stating they could not verify NCB from ICICI Lombard.
Ombudsman Ruling: The Ombudsman directed HDFC ERGO to settle the claim fully. The insurer had accepted premium based on 45% NCB and issued the policy accordingly. The verification of NCB was the insurer's responsibility at the time of policy issuance, not at the time of claim. The insurer was estopped from denying what it had already accepted.
Learning for POSP / Advisor
POSP Tips on NCB:
1. Educate customers about the value of NCB — A 50% NCB effectively halves the OD premium. It takes 5 years to build and can be lost in one claim.
2. For small claims (under ₹15,000-₹20,000), advise customers to pay out of pocket and protect their NCB.
3. Always recommend NCB Protect add-on — it costs ₹500-₹1,500 per year but preserves NCB after one claim.
4. When switching insurers, remind customers to carry their NCB proof (previous policy copy with NCB endorsed).
5. Remind customers about the 90-day renewal window — if they miss it, they lose years of accumulated NCB.
6. When a customer sells their car, remind them that NCB transfers with them to their new vehicle, not with the old car to the new owner.
Summary Notes
NCB is a cumulative discount on OD premium for claim-free years: 20% → 25% → 35% → 45% → 50% (max). It resets to 0% if a claim is made. NCB belongs to the policyholder, not the vehicle — it can be transferred to new vehicles and new insurers. The 90-day renewal window must not be missed or NCB lapses. For small claims, it is often financially better to pay out of pocket. NCB Protect add-on (₹500-₹1,500/year) preserves NCB after one claim. Always carry proof of NCB when switching insurers.
