No Claim Bonus is one of the few ways your health insurance actually gets better every year — if you do not make a claim.
The Accumulation Mechanism
For every claim-free year, most policies increase your sum insured by 5-50% without additional premium. Over several claim-free years, your effective cover can be significantly higher than what you pay for. Modern policies like Booster+ carry forward unutilised sum insured.
NCB Reduction or Loss on Claiming
In most traditional policies, making a claim reduces your accumulated NCB — sometimes to zero. This creates a dilemma: should you claim for a Rs 30,000 hospitalisation and lose Rs 50,000 of accumulated NCB? Newer policies with Safeguard add-ons protect your NCB if the claim is below a threshold.
Does Your Bonus Transfer When You Switch?
When you port to a new insurer, IRDAI requires the new insurer to give you credit for waiting periods served — but not necessarily for accumulated NCB. Some insurers honour ported NCB, others do not.
