In health insurance, No Claim Bonus (NCB) usually means your cover increases (or your premium reduces) when you don't make claims in a year. It's helpful, but you shouldn't rely on NCB as your main protection-because one big hospitalization can happen any year.
Back to: Health Insurance guide
Quick checklist (above-the-fold)
- Goal: view no-claim bonus as plan enhancement, not primary reason to buy.
- Avoid: choosing plans solely based on bonus percentage; verify actual benefit mechanics first.
- Prefer: plans with simple bonus (increased limit) over complex formulas; understand forfeiture rules.
- Claims-first: check if single claim in plan year resets entire bonus or bonus applies per member.
How NCB works: 3 common styles
| NCB type | Claim-free year | Typical benefit |
|---|---|---|
| Sum insured increase | Each claim-free year | ₹50,000–₹1,00,000 added per year (often capped at 100%) |
| Premium discount | On renewal | 5–10% premium reduction per claim-free year |
| Bonus cover bucket | After claim exhaustion | Additional ₹50,000–₹2,00,000 in same year |
What NCB does (and doesn't) do
NCB can:
- Reward claim-free years
- Improve coverage over time
NCB cannot:
- Remove waiting periods
- Prevent room rent deductions
- Fix co-pay

How NCB Actually Works: Year-by-Year Example
Let's see how NCB compounds over time with a concrete example. Assume you buy a base health insurance plan with a ₹10 lakh sum insured and ₹50,000 annual NCB per claim-free year (capped at 100% of original cover).
5-Year NCB Growth Scenario
| Year | Claim? | Base SI | NCB Added | Total SI | Notes |
|---|---|---|---|---|---|
| Year 1 | No | ₹10,00,000 | - | ₹10,00,000 | First year, no prior NCB |
| Year 2 | No | ₹10,00,000 | ₹50,000 | ₹10,50,000 | Year 1 was claim-free; earn ₹50K |
| Year 3 | Yes (₹7,50,000 claim) | ₹10,00,000 | ₹0 | ₹10,00,000 | Claim made; NCB resets |
| Year 4 | No | ₹10,00,000 | ₹50,000 | ₹10,50,000 | Year 3 claim reduced Year 3 benefit; Year 4 starts fresh NCB count |
| Year 5 | No | ₹10,00,000 | ₹1,00,000 | ₹11,00,000 | Two consecutive claim-free years (Year 4 & 5) |
Key insight: Your actual cover is only ₹11,00,000 after 5 years (11% growth), not double. And one claim in Year 3 wiped out the NCB you'd earned, forcing you to start over.
Why this matters: Many people underestimate their coverage gap because they count on NCB that hasn't happened yet. If hospitalization costs ₹15,00,000 in Year 1, your ₹10,00,000 base is all you have-NCB won't help in year one.
NCB Across Top Insurers: How They Differ
Different insurers handle NCB in different ways. This matters when you're comparing policies.
Common Approaches
Approach 1: Sum Insured Increase (Most common)
- Examples: ICICI Lombard, HDFC Ergo, Bajaj Allianz (and others)
- Your base cover grows by ₹50K–₹1,00,000 per claim-free year
- Cap: often at 100% of base (so ₹10 lakh base can reach ₹20 lakh max)
- Pro: Clear, easy to understand
- Con: Slow growth; one claim resets everything
Approach 2: Premium Discount (Less common in base plans, more in super top-ups)
- Examples: Some insurers offer 5–10% premium reduction per claim-free year
- Your cover stays the same, but you pay less
- Cap: usually 30–50% cumulative discount
- Pro: Helps with affordability over time
- Con: Doesn't expand your actual protection
Approach 3: Bonus Cover Bucket (Emerging trend)
- Examples: Certain new-age and niche insurers
- After a claim exhausts your base cover, a separate "bonus bucket" kicks in (e.g., ₹1,00,000)
- Doesn't expire until used; doesn't reset on zero claims
- Pro: More useful; doesn't reset after claims
- Con: Complex; often small bucket relative to base
Approach 4: No NCB or Limited NCB
- Examples: Some government and basic plans
- Either no NCB, or very modest NCB (₹25,000 once per 5 years)
- Pro: Transparent; no confusion
- Con: No upside reward; plan can feel expensive
How to check: Always ask your agent or look at the schedule of benefits in your policy document. "NCB terms" must be disclosed. Don't assume all NCB is equal.
Practical strategy
- Size your cover properly on day 1: How much cover do I need?
- Use NCB as upside, not a plan
- If you claim, don't panic-focus on having adequate total cover (base + super top-up)

4 Risks of Relying on NCB
NCB is attractive because it promises growing cover without buying more insurance. But there are real pitfalls:
Risk 1: NCB Resets on Any Claim
Your ₹50,000 annual bonus is gone the moment you claim-even for a minor ₹2,000 outpatient procedure (if covered) or a ₹50,000 hospitalization. You're back to your base sum insured and must start accumulating NCB from scratch. This makes NCB unreliable as core protection.
Example: You had 3 years of ₹50K NCB saved (₹1.5L extra cover). One claim wipes it out. You're now back to ₹10L base cover, not the ₹11.5L you were counting on.
Risk 2: NCB Doesn't Help in Year 1
You buy insurance on January 1. By March, you need hospitalization costing ₹12 lakhs. Your base plan is ₹10 lakhs. Your NCB is zero because you haven't completed a claim-free year. Gap: ₹2 lakhs. NCB cannot fill coverage gaps in early years-you must buy enough base + top-up on day one.
Risk 3: NCB May Not Survive Portability
When you move your policy to another insurer (portability), some NCB benefits don't transfer. Some insurers honor your NCB in a limited way, some ask for fresh documentation, and some start you at a base NCB regardless. This is often buried in policy fine print. Don't plan on NCB being part of your cover 5 years from now if you think you might switch.
Risk 4: NCB Misleads on Cover Adequacy
NCB growth (11% over 5 years in our example) is slower than healthcare inflation (6–8% annually). So while your cover grows to ₹11L, typical hospital costs may have risen 30%+. NCB makes people complacent: "My cover grew from ₹10L to ₹11L, so I'm covered." In reality, your gap may have widened due to inflation and cost increases.
Bottom line: NCB is a feature, not a safety net. Build your base + super top-up cover today for today's hospital costs. Treat NCB as a bonus that might reduce your next renewal premium or grow your cover slightly-not as protection you're counting on.
NCB vs Restoration Benefit: What's the Difference?
These are often confused because both provide additional cover. But they work very differently:
No Claim Bonus (NCB)
- When earned: After completing a claim-free year
- Applied: On renewal (next policy year)
- How much: Usually ₹50K–₹1,00,000 per claim-free year (capped at 100% of base)
- Reset condition: Any claim in the year resets it
- Used for: Additional cover in the next year
- Example: You had no claims in Year 1. On Year 2 renewal, your base ₹10L becomes ₹10.5L.
Restoration Benefit (also called "Reinstatement" or "Cover Restoration")
- When earned: After exhausting your claim this year
- Applied: In the same policy year (not next year)
- How much: Usually a percentage of the exhausted amount (e.g., 50% of claims paid, ₹50,000 fixed, or 100% restoration)
- Reset condition: Generally, doesn't reset; you can use it once per year
- Used for: Continued protection if you exhaust your SI within a year
- Example: You were hospitalized and claimed ₹8 lakhs. The restoration benefit gives you an additional ₹4 lakhs cover (50% of claim) in the same year for further hospital needs.
Side-by-Side Comparison
| Feature | NCB | Restoration |
|---|---|---|
| Timeline | Next year | Same year |
| Trigger | Completing claim-free year | Exhausting your SI |
| Reset on claim | Yes, starts over | No; can use once |
| Frequency | Annual, accumulates | Per-year benefit |
| Best for | Long-term cover growth | Immediate gaps |
Which is better?
Restoration is more useful. It protects you when you actually need it (during a hospitalization). NCB is a long-term upside that resets if you claim. A policy with a good restoration benefit (100% or 50% reinstatement) is often better than one with high NCB but weak restoration.
Should You Avoid Claims to Preserve NCB? (Very Common Misconception)
Short answer: No. Never.
This is one of the most dangerous misconceptions about NCB, and it needs to be said clearly:
Why people think this way
- NCB resets on any claim (true)
- They see their NCB grow over years (true)
- They fear "losing" the NCB by claiming (understandable fear)
- They think: "If I avoid a claim now, next year I'll earn even more NCB"
Why it's wrong
Insurance is for claims. The entire point of buying health insurance is to protect yourself when hospitalization happens. If you're avoiding claims to preserve NCB, you're:
- Paying out of pocket instead of using your insurance (defeating the purpose)
- Taking medical risk by delaying treatment (dangerous)
- Wasting your premium (because insurance only works when used)
The math proves it
Assume you have a ₹10L base plan with ₹50K annual NCB, and you've accumulated ₹2L in NCB (meaning your cover is ₹12L).
Scenario A: You claim ₹50,000 illness cost and use insurance
- Cost to you: ₹0 (covered) + lose ₹2L NCB (resets to base ₹10L)
- Net outcome: ₹50K saved, ₹2L future cover lost
- Real cost: ₹0 out-of-pocket
Scenario B: You avoid the claim to preserve ₹2L NCB
- Cost to you: ₹50,000 out-of-pocket + keep ₹2L NCB
- Net outcome: ₹50K spent, ₹2L cover preserved
- Real cost: ₹50,000 out-of-pocket
Scenario A is always better. You've saved ₹50K in today's money. Yes, you reset NCB, but you can build it back over the next 3–4 claim-free years.
Real-world example
Person with ₹10L cover has 3 years of NCB (₹1.5L extra). Gets appendicitis costing ₹3,00,000. They claim, get ₹3L paid, and reset NCB. In Year 4, they rebuild NCB. By Year 7, they're back to ₹11.5L cover. Did they make the right choice? Absolutely. They got treated, paid ₹0 out-of-pocket, and rebuilding NCB took just 3 extra years.
The cost of avoiding a necessary claim is always higher than the cost of resetting NCB.

FAQs
Does making a small claim remove NCB?
Usually yes-any claim can impact NCB, but rules vary. Some policies have a ₹5,000 threshold below which NCB isn't impacted, but this is rare. Check your plan document.
Is it better not to claim to preserve NCB?
No. That's a dangerous misconception. Never avoid medical claims to preserve NCB. Insurance is for protection. Resetting NCB is the cost of using your insurance-and rebuilding it takes 3–4 years. Out-of-pocket costs are always higher.
Does NCB carry forward if I switch insurers?
Portability may preserve some benefits, but NCB treatment varies significantly. Some insurers honor 50% of your NCB, some honor it in full but reset it, and some start you fresh. Always confirm with your new insurer before porting.
Is NCB the same as restoration?
No. Restoration refills your cover within the same year after a claim. NCB grows your cover in the next year after a claim-free year. Restoration is more useful.
Can NCB make my cover double?
Some policies allow cumulative NCB up to 100% of base (so ₹10L base can reach ₹20L max). But this takes 10 claim-free years. Due to claim resets, most people don't reach this cap.
Does NCB apply to super top-ups?
Depends on the product. Some super top-ups have their own NCB, some don't. Always check the product brochure.
Does NCB reduce premium or increase cover?
Either, depending on plan variant. Some plans increase your sum insured; others reduce your premium on renewal. Confirm which before buying.
Should I rely on NCB instead of buying a super top-up?
No. Buy your super top-up based on today's cover needs, not future NCB. Use NCB as a bonus that reduces your premium or grows cover incrementally-not as a substitute for adequate base + top-up.
What happens to NCB if I miss a premium payment?
Typically, if your policy lapses due to non-payment, NCB is lost. You may regain it if you revive the policy within a grace period (usually 30 days), but confirm with your insurer.
How is NCB calculated if I have multiple policies?
NCB is usually policy-specific-calculated per policy, not across all your policies. If you have a base plan and a super top-up, they earn NCB separately. This is why structure (base + top-up) is clearer than trying to have one mega-policy.
