The No Claim Bonus, commonly shortened to NCB, is one of the most rewarding yet misunderstood features of Indian car insurance. It is a discount you earn simply by driving carefully and not making a claim, and over several years it can slash your renewal premium substantially. Yet many owners lose this valuable benefit through avoidable mistakes, such as claiming for tiny repairs or letting their policy lapse.
At its heart, NCB is a reward for responsible ownership. Insurers use it to encourage safe driving and to discourage frequent small claims that push up costs for everyone. The more consecutive claim-free years you accumulate, the bigger the discount grows, up to a maximum level. Understanding how it builds, how it resets, and how to protect it can save you a meaningful amount of money.
This article explains everything about NCB in the Indian context regulated by IRDAI, from the way it is calculated on the own-damage premium to how it transfers when you sell your car or switch insurers. It also covers the NCB protection add-on, which lets you make a limited number of claims without wiping out your hard-earned discount, and clears up common myths.
Whether you are a new car owner keen to start building your bonus, or an experienced driver with several claim-free years behind you, knowing how NCB works helps you make smarter decisions. You will learn when it makes sense to skip a small claim, how to avoid losing the bonus at renewal, and how to carry it forward to keep your premiums low for years to come.

What the No Claim Bonus Really Is
The No Claim Bonus is a discount applied to your car insurance premium as a reward for not making any claim during a policy year. It is calculated only on the own-damage portion of the premium, not on the third-party portion or on add-ons. This is why NCB matters most for comprehensive and standalone own-damage policyholders, who have an own-damage premium for the discount to reduce.
The bonus is earned year by year. After your first claim-free year, you qualify for an initial discount at the next renewal, and this percentage rises with each additional consecutive claim-free year up to a ceiling. It is a cumulative reward, so a long stretch of careful, claim-free driving translates into a significant reduction in what you pay each year.
Importantly, NCB belongs to you the policyholder, not to the car itself. This distinction has practical consequences: when you sell one car and buy another, you can carry your accumulated bonus to the new vehicle’s policy. Understanding this personal ownership of the bonus is key to using it wisely across the cars you own over your driving lifetime.
- A discount for claim-free policy years
- Applied only on the own-damage premium
- Grows cumulatively with each claim-free year
- Belongs to the policyholder, not the car
- Most valuable on comprehensive policies
How the NCB Slabs Grow Over the Years
The NCB follows a structured set of slabs that increase with each consecutive claim-free year. Typically the discount begins at around twenty percent after the first claim-free year, rises to about twenty-five percent after the second, then thirty-five percent, forty-five percent, and reaches a maximum of around fifty percent after five consecutive claim-free years. It does not increase beyond this ceiling.
Each slab is reached only if you complete a full policy year without any own-damage claim. Once you hit the top slab, you continue to enjoy the maximum discount as long as you keep renewing on time and stay claim-free. This makes the fifth year and beyond particularly valuable, since your renewal premium settles at its lowest own-damage cost.
Because the bonus applies to the own-damage premium, its rupee value depends on your car’s IDV and the size of that premium. On a newer, higher-value car the own-damage premium is larger, so a fifty percent discount saves more in absolute terms. As the car ages and IDV falls, the percentage stays the same but the actual saving reduces along with the premium.
Typical NCB Discount Slabs
This table shows how the No Claim Bonus discount usually grows with consecutive claim-free years.
| Consecutive Claim-Free Years | Typical NCB Discount |
|---|---|
| After 1 year | Around 20 percent |
| After 2 years | Around 25 percent |
| After 3 years | Around 35 percent |
| After 4 years | Around 45 percent |
| After 5 years and beyond | Around 50 percent |

How a Single Claim Resets Your Bonus
The flip side of the NCB is that making even one own-damage claim during a policy year usually resets your bonus to zero at the next renewal. This means years of accumulated discount can vanish because of a single small claim. It is a crucial point that many owners overlook when they rush to claim for a minor scratch or dent.
Because of this reset, there is often a smart calculation to make before claiming small amounts. If the repair cost is only slightly more than your compulsory deductible and you would lose a large accumulated bonus, it can be cheaper in the long run to pay for the repair yourself and keep your NCB intact. The bonus you preserve may outweigh the small claim you forgo.
This is precisely why the NCB protection add-on exists, and why experienced owners think carefully about which incidents are worth claiming. Understanding the reset rule turns the NCB from a passive discount into an active tool: you decide, on each minor incident, whether claiming or self-paying leaves you better off over the next renewal cycle.
- One own-damage claim usually resets NCB to zero
- Years of accumulated discount can be lost at once
- Weigh small repair cost against the bonus you would lose
- Self-paying tiny repairs can preserve a large bonus
- The reset rule makes NCB an active decision tool
Transferring NCB When You Sell Your Car
Since the NCB belongs to you and not the car, you keep your accumulated bonus when you sell your vehicle. The bonus does not pass to the buyer of your old car; instead, you obtain an NCB retention letter or certificate from your insurer, which records your entitlement. You can then apply this bonus to the policy of the new car you purchase.
To transfer the bonus, request the NCB certificate from your existing insurer when you sell the car or when your policy is due, and present it when insuring the new vehicle. There is usually a time window within which the bonus must be carried forward, so do not delay. The new insurer applies the discount slab you had earned, continuing your claim-free reward on the new car.
This portability is a strong reason to keep your bonus intact even when changing cars. A driver who has built up the maximum discount over five years can immediately enjoy a large reduction on the own-damage premium of a brand-new car, which is exactly when the own-damage premium is highest. Handled correctly, NCB rewards a lifetime of careful driving across multiple vehicles.
- NCB stays with you, not the sold car
- Obtain an NCB retention certificate from your insurer
- Apply the bonus to your new car’s policy
- Carry it forward within the allowed time window
- Maximum bonus greatly cuts a new car’s premium

The NCB Protection Add-On Explained
The NCB protection add-on is a paid cover that lets you make a limited number of claims within a policy year without losing your accumulated bonus. In effect, it shields your discount from the usual reset rule, so a single unavoidable claim does not wipe out years of careful driving. For owners with a high bonus who face real claim risk, it can be very worthwhile.
Each insurer sets its own terms for the add-on, typically allowing one or two claims before the protection is affected, and often with conditions on the type and size of claim. The add-on adds a small amount to your premium, but for someone sitting on a forty or fifty percent bonus, protecting that discount can easily justify the modest extra cost.
It is important to read the exact conditions, because the add-on may still step down your bonus by a slab after using the permitted claims, rather than keeping it completely untouched. Even so, it softens the blow considerably compared with a full reset. For high-bonus owners in busy driving conditions, the NCB protection add-on is often a sensible companion to zero depreciation cover.
- Allows limited claims without full NCB reset
- Shields a high accumulated discount from a single claim
- Adds a small amount to the premium
- Terms and permitted claims vary by insurer
- May step the bonus down a slab rather than reset fully
How Policy Lapse Affects Your NCB
Letting your policy lapse is one of the most common ways owners accidentally lose their No Claim Bonus. If you do not renew before expiry and the gap stretches beyond a permitted grace period, typically around ninety days, the accumulated bonus is forfeited entirely. This can undo several years of careful driving simply because a renewal date was missed.
To protect your bonus, renew your policy on or before the expiry date, and set reminders well in advance. If you know you will be away or unable to renew on time, arrange it early. Some owners lose their bonus not through claims but through pure oversight, so treating the renewal date as a hard deadline is essential to keeping your discount alive.
If your policy has already lapsed but is still within the grace period, renewing promptly usually preserves your bonus. Beyond that window, you generally start again from zero on your next policy. Because the bonus can be worth a large percentage of your own-damage premium, avoiding lapse is one of the easiest and most valuable habits a careful owner can maintain.
- Lapse beyond the grace period forfeits your NCB
- The grace period is typically around ninety days
- Renew on or before expiry to keep the bonus
- Set early reminders for the renewal date
- Prompt renewal within grace usually preserves NCB

Deciding When to Claim and When to Skip
Every minor incident presents a choice: claim and risk resetting your bonus, or pay the repair yourself and keep the discount. A useful rule of thumb is to compare the repair amount, after subtracting your compulsory deductible, against the extra premium you would pay next year from losing your NCB. If the bonus saving is larger, self-paying often makes more sense.
For small cosmetic repairs like a minor dent or scratch, the workshop bill may be modest, while the bonus at stake could be substantial if you have several claim-free years. In such cases, absorbing the repair cost preserves a discount that will keep lowering your premium for years. For large repairs after a serious accident, claiming is almost always the right move despite the reset.
If you hold an NCB protection add-on, this calculation becomes easier, because a permitted claim need not reset your bonus. Without it, a disciplined approach of self-funding tiny repairs and claiming only for significant damage helps you build and maintain a high NCB. Over a car’s life, this discipline can translate into considerable savings on renewal premiums.
- Compare repair cost against next year’s premium rise
- Self-pay small repairs to protect a large bonus
- Claim without hesitation for serious, costly damage
- NCB protection makes permitted claims safer
- Discipline on small claims builds a high bonus
Common Myths and Mistakes About NCB
A widespread myth is that the No Claim Bonus is tied to the car, so owners wrongly believe they lose it when they sell the vehicle. In reality it belongs to you and can be transferred to a new car. Another misconception is that a third-party claim resets the bonus; since NCB relates to own-damage, a pure third-party liability claim does not reduce your own-damage discount in the usual way.
Some owners assume the bonus keeps rising indefinitely, but it caps at a maximum slab, commonly around fifty percent, after which it plateaus. Others think buying a new car means starting from zero, forgetting that they can carry forward their existing bonus with a retention certificate. These misunderstandings lead people to make poorer decisions than they need to.
The costliest mistake, though, is losing the bonus through policy lapse or unnecessary small claims. Both are avoidable with a little planning: renew on time and think before claiming trivial amounts. Treating your NCB as a valuable asset, understanding its rules, and using tools like the protection add-on where appropriate ensures you extract its full benefit over many years of ownership.
- Myth: NCB is tied to the car, not the owner
- Myth: a third-party claim resets your bonus
- Myth: the bonus rises without any ceiling
- Reality: you can carry the bonus to a new car
- Biggest mistakes are lapse and needless small claims
Frequently Asked Questions
What is No Claim Bonus in car insurance?
No Claim Bonus is a discount you earn on your car insurance premium for every policy year in which you do not make a claim. It applies only to the own-damage portion of the premium and grows cumulatively with each claim-free year up to a maximum. The bonus belongs to you as the policyholder, not to the car. It is a reward for safe, claim-free driving.
How much can the No Claim Bonus save me?
The NCB typically starts at around twenty percent after one claim-free year and rises to about fifty percent after five consecutive claim-free years. It applies to the own-damage premium, so the rupee saving is larger on newer, higher-value cars. Over several years the cumulative discount can significantly cut your renewal cost. The maximum discount then continues as long as you stay claim-free and renew on time.
Does making a claim cancel my NCB?
Yes, making an own-damage claim usually resets your No Claim Bonus to zero at the next renewal, unless you hold an NCB protection add-on. This is why it can be wise to pay for very small repairs yourself and preserve a large accumulated bonus. Weigh the repair cost against the discount you would lose. For major damage, claiming is still the sensible choice despite the reset.
Can I transfer my NCB to a new car?
Yes, because the bonus belongs to you and not the vehicle, you can transfer it when you sell one car and buy another. You obtain an NCB retention certificate from your insurer and apply the bonus to the new car’s policy. This must be done within the allowed time window. It lets you enjoy a large discount on a new car’s own-damage premium immediately.
What happens to my NCB if my policy lapses?
If your policy lapses and the gap exceeds the grace period, typically around ninety days, your accumulated No Claim Bonus is forfeited entirely. Renewing promptly within the grace period usually preserves the bonus. This is why renewing on or before the expiry date is so important. Missing the renewal date is a common and avoidable way to lose years of earned discount.
Is NCB linked to the car or the owner?
NCB is linked to the owner as the policyholder, not to the car. This means you keep the bonus when you sell your vehicle and can transfer it to a new one using a retention certificate. The buyer of your old car does not inherit your bonus. Understanding this helps you use the discount across all the cars you own over time.
What is the NCB protection add-on?
The NCB protection add-on is a paid cover that lets you make a limited number of claims in a policy year without losing your accumulated bonus. It shields a high discount from being reset by a single unavoidable claim. Terms vary by insurer, and it may step the bonus down a slab rather than keep it fully intact. For high-bonus owners facing real claim risk, it is often worthwhile.
Does a third-party claim affect my No Claim Bonus?
A pure third-party liability claim generally does not reset your own-damage No Claim Bonus, because the bonus relates to the own-damage premium. However, if the same incident also involves an own-damage claim, that own-damage claim can reset the bonus. It is a common misconception that any claim automatically cancels the NCB. Understanding this distinction helps you assess the impact of each claim accurately.
How many years does it take to reach maximum NCB?
It typically takes five consecutive claim-free years to reach the maximum bonus of around fifty percent. Each claim-free year moves you up one slab until you hit the ceiling. After that, the discount plateaus and continues at the maximum as long as you stay claim-free and renew on time. A single claim during this period can reset the accumulation.
Should I always avoid claiming to protect my NCB?
Not always. For very small repairs, self-paying can make sense to preserve a large bonus, but for significant damage after a serious accident, claiming is the right move despite the reset. Compare the repair cost, after your deductible, against the extra premium you would pay from losing the bonus. If you hold an NCB protection add-on, permitted claims need not reset your discount. Judge each case on its numbers.
