A discount that can reach 50% of your Own Damage premium is genuinely worth protecting deliberately, and a single small, avoidable claim can wipe out years of accumulated savings in one single renewal cycle, worth understanding this mechanic clearly before deciding whether to file a claim for a minor incident.
What No Claim Bonus Actually Is
No Claim Bonus (NCB) is a discount on your Own Damage premium, earned for each consecutive policy year in which you don't make a claim, it starts at 20% after your first claim-free year, and progressively increases with each further claim-free year, up to a current maximum of 50%.
NCB Applies Only to the Own Damage Premium, Not the Full Policy
This is a detail worth understanding clearly, your NCB discount reduces only the Own Damage portion of your comprehensive premium, the fixed third-party premium, as discussed in our third-party versus comprehensive guide, is unaffected by your NCB status entirely.
Filing a Single Claim Resets Your NCB Back to Zero
Making even one claim in a policy year, regardless of the amount, resets your accumulated NCB discount back to 0% for the following renewal, this is precisely why filing a claim for a genuinely minor repair, one you could reasonably afford out of pocket, is often not the financially optimal choice once you weigh the lost NCB discount against the modest repair cost.
A Worked Example of Why a Small Claim Can Cost More Than It Saves
Say you have a 40% NCB on a ₹15,000 Own Damage premium, worth ₹6,000 in annual savings. A minor claim for a ₹5,000 repair, if filed, resets your NCB to 0%, costing you this ₹6,000 discount (and more in subsequent years as it would otherwise have continued climbing toward 50%), for a repair that cost less than the discount you're giving up, worth calculating this specific trade-off honestly before filing a claim for a genuinely minor amount.
NCB Is Lost If Your Policy Lapses Beyond a Specific Window
If you let your comprehensive policy lapse for more than 90 days without renewal, your accumulated NCB is forfeited entirely, this is a genuinely important detail to keep in mind if you're between vehicles or considering a temporary insurance gap, worth renewing on time specifically to preserve this accumulated benefit.
NCB Belongs to You, Not the Vehicle
A genuinely useful, often overlooked feature is that your accumulated NCB is tied to you as the policyholder, not the specific vehicle, if you sell your car and buy a new one, you can transfer your accumulated NCB to the new vehicle's policy, rather than starting fresh at 0%, worth specifically requesting this NCB transfer certificate from your previous insurer when selling a vehicle.
How NCB Transfers When Switching Insurers
Similarly, if you switch to a different insurer at renewal, your accumulated NCB carries over, provided you obtain and submit the NCB certificate from your previous insurer, worth requesting this document proactively rather than assuming the new insurer will automatically retrieve it.
Does NCB Transfer to a Second Vehicle If You Own Multiple Cars?
No, NCB is specifically tied to one policyholder-vehicle relationship at a time, if you own multiple vehicles, each has its own separate NCB track record, you can't apply one vehicle's accumulated NCB toward a different vehicle you also own simultaneously.
A Practical Way to Decide Whether to File a Specific Claim
- Calculate the rupee value of your current NCB discount level against your Own Damage premium
- Compare this against the cost of the repair you're considering claiming for
- If the repair cost is genuinely modest relative to your NCB value, paying out of pocket often makes more financial sense
- Reserve your claim for genuinely significant damage where the repair cost clearly exceeds your NCB value
Frequently Asked Questions
Does a third-party-only claim (not involving my own vehicle's damage) affect my NCB?
Since NCB applies specifically to the Own Damage premium, a purely third-party claim not involving damage to your own vehicle generally doesn't affect your NCB, worth confirming this specific treatment with your insurer.
Can I check my current NCB percentage before renewal?
Yes, your renewal notice or policy document typically states your current NCB level, worth confirming this figure is correctly reflected, particularly if you've recently switched insurers or vehicles.
Is there a maximum NCB percentage I can ever reach?
Yes, the current maximum is 50%, reached after a sustained number of consecutive claim-free years, it doesn't continue increasing indefinitely beyond this cap.
What happens to my NCB if I add a driver to my policy who then causes an accident?
If a claim is filed as a result, this affects the policy's NCB the same way any claim would, regardless of which authorised driver was operating the vehicle at the time.
