No-Claim Bonus in Motor Insurance: How to Earn and Protect It

---

If you've never made a motor insurance claim, you're sitting on real money. India's No-Claim Bonus (NCB) system rewards safe drivers with discounts of up to 50% on their own-damage premium — a saving that can compound into tens of thousands of rupees over five years of careful driving. Yet most Indian car owners have no idea how NCB works, how to transfer it, or how a single small claim can wipe out years of accumulated discount. To understand all the ways to save on car insurance beyond NCB, see our guide on how to reduce your car insurance premium in India. For context on what base cover to build NCB on, read our comparison of zero depreciation cover and our guide on third-party vs comprehensive car insurance.

This guide explains everything you need to know about NCB in motor insurance India — in plain language.

What is No-Claim Bonus (NCB)?

NCB is a discount on the Own Damage (OD) component of your motor insurance premium, earned for every claim-free policy year. It applies only to the OD premium — not to the mandatory third-party (TP) premium, which is fixed by IRDAI regardless of your claims history.

The IRDAI mandates a standard NCB slab structure for all motor insurers in India:

Claim-free Years	NCB Discount on OD Premium
1 year	20%
2 consecutive years	25%
3 consecutive years	35%
4 consecutive years	45%
5 or more consecutive years	50%

How NCB is Calculated

NCB is applied to the Own Damage premium, not the total premium. Understanding this distinction matters because TP premium constitutes a significant portion of the total for older vehicles.

Example calculation for a 3-year-old mid-size sedan in Delhi:

• OD premium (before NCB): ₹18,000
• TP premium (fixed by IRDAI): ₹3,278
• NCB discount at 35% (3 claim-free years): 35% × ₹18,000 = ₹6,300 discount
• Net OD premium: ₹11,700
• Total premium payable: ₹11,700 + ₹3,278 = ₹14,978

Key Rules About NCB

NCB Belongs to the Owner, Not the Vehicle

This is the most important and most misunderstood rule about NCB in India. When you sell your car, the NCB stays with you — you take it to your next vehicle. The buyer of your car gets no NCB benefit. When buying a new car, you can apply your existing NCB earned on your old car.

To transfer NCB, you need an NCB Retention Certificate or NCB Transfer Letter from your current insurer, issued within 3 years of policy expiry. Don't delay getting this document when selling a car.

NCB Resets to Zero After a Claim

Any claim on the Own Damage section — whether you claim ₹3,000 for a scratched bumper or ₹3 lakh for a major accident — resets your NCB to zero. You start the five-year accumulation journey from scratch. This is why small claims often don't make financial sense.

Third-Party Claims Don't Affect Your NCB

If someone else's vehicle damages yours and you claim against their third-party insurance, your NCB is unaffected. Similarly, if you make a claim only under the TP liability section of your policy (you hit someone else), your OD NCB is retained.

Lapse in Renewal Kills NCB

If your policy lapses (expires without renewal), you have a 90-day window to renew and retain your NCB. Beyond 90 days, your NCB is forfeited. Insurers like ICICI Lombard and HDFC ERGO enforce this strictly — a single year of uninsured driving wipes out five years of NCB accumulation.

NCB Protection Add-on: Should You Buy It?

NCB Protection is an add-on cover available from most comprehensive policy providers — HDFC ERGO, Bajaj Allianz, Tata AIG, ICICI Lombard, Reliance General — that allows you to make one or two claims in a policy year without losing your accumulated NCB.

How Much Does NCB Protection Cost?

Insurer	NCB Protection Cost (approx.)	Claims Allowed Without NCB Reset
HDFC ERGO	₹600–900/year	1 own-damage claim
Bajaj Allianz	₹500–800/year	1 own-damage claim
Tata AIG	₹700–1,000/year	1 own-damage claim
ICICI Lombard	₹550–850/year	1 own-damage claim

Is NCB Protection Worth Buying?

The math is straightforward. If your NCB is at 50%, you're saving, say, ₹8,000/year on your OD premium. A single claim without protection would reset this to zero — costing you ₹8,000/year extra for the next 5 years (₹40,000 total). NCB protection at ₹700/year is a no-brainer if your NCB is 35% or higher.

For low NCB slabs (20%), the trade-off is less compelling — the NCB loss from a reset is smaller and the protection add-on adds cost. Buy NCB protection once you reach 35%+ NCB and have an asset worth protecting.

When Not to Make a Claim

Knowing when to pay out of pocket is as important as knowing how to use insurance. The general rule: if the claim amount is less than your NCB discount for the next renewal, pay out of pocket.

Example: Your car gets a minor dent. Repair estimate: ₹8,000. Your OD premium is ₹20,000 at 45% NCB, saving you ₹9,000 this year. If you claim ₹8,000, your NCB resets to 0% next year, costing you ₹9,000 extra premium. Net outcome: you claim ₹8,000 but pay ₹9,000 more next year — a net loss of ₹1,000 in year 1, and further loss in years 2–5 as you rebuild NCB.

Pay out of pocket for:

• Minor dents, scratches, or surface damage under ₹10,000
• Windshield chips if not covered by zero-dep or separate windshield cover
• Any claim amount lower than your annual NCB saving

NCB Transfer When Changing Insurers

You can port your NCB to any new insurer at renewal without losing it. This is important because you should not feel trapped with a poor-quality insurer just because you have accumulated NCB there. IRDAI's portability rules protect your NCB across insurer switches.

Process:

1. Get an NCB confirmation letter or verify NCB on the insurer's app/portal before renewal
2. Share this with your new insurer at the time of fresh policy issuance
3. The new insurer applies the same NCB slab at inception
4. Some insurers verify NCB via IIB (Insurance Information Bureau) data — keep your records clean

Common NCB Mistakes to Avoid

• Claiming for small repairs: As shown above, small claims destroy disproportionate long-term NCB value
• Not getting NCB certificate when selling a car: This document expires 3 years from policy end date — get it immediately when selling
• Letting policy lapse during vehicle sale: Gap in coverage forfeits NCB and creates legal risk
• Forgetting NCB protection when renewing: It's a small cost for significant protection — add it every year at 35%+ NCB
• Assuming NCB transfers with the vehicle: It does not — it transfers with the owner
