No Claim Bonus in Health Insurance: How NCB Works 2026

What is No Claim Bonus (NCB) in Health Insurance?

On several public-sector plans the same claim-free record also gates the annual health check-up, so a small claim can cost more than the bonus.

No Claim Bonus (NCB) in health insurance is a reward that insurers provide for each claim-free policy year. Depending on the plan, NCB either increases your sum insured (typically by ₹50,000–₹1 lakh per year, capped at 50–100% of the original base) or reduces your renewal premium (by 5–10% per claim-free year). On most plans, a claim during a policy year reduces or resets the bonus you have built up. A guaranteed bonus works differently: HDFC ERGO Optima Secure Plus (its Infinite Benefit) and Care Supreme add their bonus even in a year you claim.

Every premium on this page is the full amount you pay. Individual health insurance has attracted nil GST since 22 September 2025, so there is nothing to add on top.

While NCB provides a welcome long-term benefit, it should never be your primary coverage strategy. NCB growth of 10–20% over 5 years is significantly slower than India's medical inflation rate of approximately 13% to 14% per year. This means your coverage gap may actually widen over time despite NCB. More importantly, on most plans a single hospitalization can wipe out the bonus you have built up, unless your plan's bonus is guaranteed. The practical approach: size your base + super top-up cover correctly on day 1, and treat NCB as upside – never avoid a legitimate medical claim just to preserve your NCB.

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 whether a claim reduces the bonus, resets it to zero, or leaves it untouched (a guaranteed bonus), and whether it applies per member.

How NCB works: 3 common styles

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

Key reads:

• Room rent limit
• Waiting periods

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), on a plan whose bonus resets after any claim.

5-Year NCB Growth Scenario

Key insight: Your actual cover is only ₹11,00,000 after 5 years (10% growth), not double. And the one claim in Year 2 wiped out the NCB you'd earned, forcing you to start over. On a plan with a guaranteed bonus, such as HDFC ERGO Optima Secure Plus or Care Supreme, that claim would not have cost you the bonus.

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 General (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, and on most plans a claim reduces or resets the bonus – though not all. HDFC ERGO Optima Secure Plus adds its Infinite Benefit regardless of claims, and Care Supreme's 50% yearly bonus is guaranteed, so a claim does not take it away. Check which behaviour your plan has before you decide against a small claim. How six plans' bonus rules play out over ten years, with and without a claim, is charted in unlimited sum insured and big-bonus plans.

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: A Claim Can Cost You the Bonus

On most plans, a claim reduces your accumulated bonus or resets it to zero – even for a minor ₹2,000 outpatient procedure (if covered) or a ₹50,000 hospitalization. On a plan that resets, you're back to your base sum insured and must start accumulating NCB from scratch. This makes NCB unreliable as core protection. A guaranteed bonus is the exception: HDFC ERGO Optima Secure Plus (its Infinite Benefit) and Care Supreme add their bonus even in a year you claim.

Example: On a plan that resets, 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: How a Ported NCB Shows Up Is Not Spelled Out

When you move your policy to another insurer (portability), IRDAI's Master Circular on Health Insurance Business (29 May 2024, Chapter I, para 12(d)) entitles you to transfer the credits gained to the extent of the sum insured and no-claim bonus, along with your waiting periods and moratorium. The circular does not say how the new insurer must show that bonus on its schedule, so get the figure in writing before you switch. See what the circular says about bonus on porting.

Risk 4: NCB Misleads on Cover Adequacy

NCB growth (10% over 5 years in our example) is far slower than medical inflation, which runs around 13% to 14% a year. 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: On most plans a claim reduces or resets it; a guaranteed bonus is not affected
• 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

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, on most plans, shrinks or 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

• On most plans, a claim reduces or resets the bonus (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 that resets after a claim, 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 4 claim-free years.

Real-world example

Person with ₹10L cover on a plan whose bonus resets has 3 years of NCB (₹1.5L extra). In Year 4 they get appendicitis costing ₹3,00,000. They claim, get ₹3L paid, and the bonus resets at renewal. After three claim-free years, in Year 8, 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 3 claim-free years.

The cost of avoiding a necessary claim is always higher than the cost of losing the bonus.

FAQs

Does making a small claim remove NCB?

On most plans, yes – any claim, however small, can reduce or reset a no-claim bonus. A guaranteed bonus is different: HDFC ERGO Optima Secure Plus (its Infinite Benefit) and Care Supreme add their bonus even in a year you claim. Check your plan's policy wording.

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. On most plans, losing some or all of the bonus is the cost of using your insurance – and rebuilding it takes a few claim-free years. Out-of-pocket costs are always higher.

Does NCB carry forward if I switch insurers?

Yes, by IRDAI rule. The Master Circular on Health Insurance Business (29 May 2024) entitles you to transfer credits to the extent of the sum insured and no-claim bonus when you port. It does not say how the new insurer must show the bonus, so confirm the figure in writing 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?

Yes, on many plans. A cumulative bonus capped at 100% of base takes a ₹10L cover to ₹20L. How long that takes depends on the rate: 2 claim-free years at 50% a year, 10 years at 10% a year. On plans whose bonus shrinks or resets after a claim, many people never reach the cap, while a guaranteed bonus keeps being added even in a year you claim.

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.
