Work out no claim bonus accumulation instantly with clear inputs, formula shown and shareable results.
A cumulative bonus increases the sum insured by a set percentage for each claim-free year, up to a cap, at no extra premium. Making a claim usually resets or reduces the accumulated bonus, which is why small claims are often worth funding yourself.

Rate = min(Bonus per year x Claim-free years, Cap)
Effective sum insured
Effective = Base sum insured x (1 + Accrued bonus rate)
