Cumulative Bonus

Cumulative bonus is the accumulating increase in a health policy's sum insured granted for each consecutive claim-free year.

Each claim-free year adds a set percentage to the base sum insured, accumulating up to a cap (some plans allow the cover to multiply substantially over several claim-free years). The enhanced cover is provided at no additional premium, helping the policyholder keep pace with rising medical costs.

The bonus typically reduces if a claim is filed, unless the plan offers a 'bonus protect' feature. Cumulative bonus differs from restoration, which refills exhausted cover within a year, and from a premium-discount style no-claim bonus.
