No-Claim Bonus in Indian Health Insurance: What You Earn, and What One Claim Costs You
A no-claim bonus can lift a Rs 5 lakh policy to Rs 10 lakh over several claim-free years at no extra premium. Making one claim can undo years of it — which is why a small claim is sometimes worth paying yourself.
The short version
- In Indian health insurance the bonus almost always increases your sum insured rather than cutting your premium.
- Typical terms add 10% to 50% of the base sum insured per claim-free year, capped at 50% to 100% of it.
- Making a claim usually reduces the accumulated bonus rather than wiping it out — commonly by one year's worth.
- Before claiming a small amount, compare it against the bonus you would forfeit. Sometimes paying the bill yourself is the cheaper decision.
- The bonus is extra cover at zero premium, which makes it the cheapest sum insured you will ever obtain.
The short answer
A no-claim bonus rewards a claim-free year. In motor insurance the reward is a premium discount; in Indian health insurance it is almost always additional sum insured instead. Your premium stays on its usual track, but the cover it buys grows.
This distinction matters more than it sounds. Extra sum insured at no additional premium is the cheapest cover available anywhere in the market, and against medical inflation it is the mechanism that stops a policy bought years ago from becoming inadequate.
How the accrual usually works
Terms vary between insurers, but the shape is consistent: a fixed percentage of the base sum insured is added for each claim-free year, until a ceiling is reached.
Some plans market a much faster accrual, doubling cover in two or three years. Read those carefully: a fast bonus is occasionally paired with a harsher reduction on claim, or with sub-limits that constrain what the enlarged sum insured is actually good for. The headline rate is not the whole product.
| Policy year | Claim-free? | Bonus added | Cover on a Rs 5 lakh base at 20% a year |
|---|---|---|---|
| Year 1 | — | — | Rs 5,00,000 |
| Year 2 | Yes | +20% | Rs 6,00,000 |
| Year 3 | Yes | +20% | Rs 7,00,000 |
| Year 4 | Yes | +20% | Rs 8,00,000 |
| Year 5 | Yes | +20% | Rs 9,00,000 |
| Year 6 | Yes | +20% | Rs 10,00,000 (capped at 100%) |
What one claim actually costs
Most policies reduce the accumulated bonus after a claim rather than erasing it. A common structure removes one year's worth — so a policyholder who had built 60% might drop back to 40%, not to zero. Some plans reduce it more aggressively, and a few protect it entirely for the first claim.
That makes the small claim a genuine decision rather than an automatic one. Suppose you hold a Rs 5 lakh base policy with 60% bonus accrued, on terms that remove 20 percentage points per claim. A Rs 18,000 hospitalisation claim would recover Rs 18,000 today and cost you Rs 1,00,000 of cover you had already earned. Whether that trade is sensible depends on how close you are to the cap and how likely you are to need the headroom, but it is plainly not free.
The arithmetic reverses for a large claim. Nobody should hesitate over a Rs 4 lakh hospitalisation to protect a bonus — the cover exists to be used, and declining to claim in order to preserve a bonus is the tail wagging the dog.
The practical rule
For a claim smaller than the sum insured you would forfeit, work out both numbers before you file. For anything substantial, claim without hesitation.
Bonus, restoration, and top-up are three different things
These are routinely confused because all three increase the cover available to you, but they trigger in entirely different circumstances and they stack rather than substitute.
Restoration conditions repay close reading. Some plans restore only for an unrelated illness, so a second admission for the same condition does not benefit. Others restore only once per year, or only after the base sum insured is fully exhausted rather than partly used. These conditions decide whether the feature helps in the situation you would actually face.
| Feature | When it applies | What it gives you |
|---|---|---|
| No-claim bonus | After a claim-free year | Permanent increase in sum insured, at no extra premium |
| Restoration / refill | When the sum insured is exhausted mid-year | Reinstates cover for further claims that year, usually with conditions |
| Top-up / super top-up | Above a chosen deductible | Separate policy providing high cover cheaply above a threshold |
Protecting the bonus when you change insurer
An accumulated bonus is real value, and it is one of the things you stand to lose by moving insurer carelessly. Where you port a policy properly, the bonus generally carries across — most often as additional sum insured with the new insurer.
Where you simply lapse the old policy and buy a fresh one elsewhere, it is gone along with your accrued waiting periods. Confirm in writing how an incoming insurer will treat the bonus before committing, because the mechanics differ and a bonus recognised as sum insured by one insurer is not always recognised identically by another.
A lapse in cover generally forfeits the bonus as well, though many insurers restore it if the policy is renewed inside the grace period. That is one more reason to treat the renewal date as a hard deadline rather than a suggestion.
Common questions
Does a no-claim bonus reduce my premium?
In Indian health insurance, usually not. The bonus almost always increases your sum insured instead, so the premium follows its normal age-related path while the cover it buys grows. Premium-discount bonuses are the motor insurance model.
Do I lose the whole bonus if I make one claim?
Usually not. Most policies reduce the accumulated bonus by one year's worth rather than resetting it to zero, though terms vary and some plans are harsher. A few offer bonus protection that preserves it through the first claim.
Should I avoid claiming a small amount to protect my bonus?
It is worth calculating. Compare the claim amount against the sum insured you would forfeit — for a small claim, the forfeited cover is sometimes worth more than the reimbursement. For any substantial claim, file it; preserving a bonus is not a reason to leave a large bill unpaid.
Is the bonus lost if I port to another insurer?
Not if you port properly — the bonus generally transfers, most often as additional sum insured. It is lost if you let the old policy lapse and buy fresh cover elsewhere instead of porting.
What is the difference between a no-claim bonus and restoration?
A no-claim bonus permanently increases your sum insured as a reward for a claim-free year. Restoration reinstates cover within a policy year once the sum insured has been used up. They are independent features and a policy can carry both.
