An excess loss premium factor is a retrospective-rating charge that helps fund the protection created when a workers compensation plan limits large individual losses. In plain language, it is part of the pricing that compensates the insurer when the insured chooses a loss-limitation feature inside a retrospective rating plan.
Why the factor exists
Under retrospective rating, the final premium depends in part on the insured’s actual loss experience. Some plans include a large-loss limitation so a single severe claim does not fully flow into the retrospective premium calculation.
That limitation benefits the insured, but it also shifts part of the large-loss risk back to the insurer. The excess loss premium factor is one of the tools used to charge for that extra protection.
How it fits into the plan
The exact formula depends on the rating plan and jurisdiction, but the basic mechanics are:
- actual losses influence the retrospective premium
- very large losses may be capped for rating purposes
- the insurer adds pricing elements to reflect the cost of that cap
- the excess loss premium factor helps recover that cost
This is a pricing term, not a coverage term. It affects how the final premium is calculated, not whether the workers compensation claim itself is covered.
Practical example
A large employer uses workers compensation retrospective rating with a per-loss limitation. One severe claim generates costs far above that limit. The retrospective formula caps how much of that claim enters the premium calculation, and the excess loss premium factor is part of the pricing structure that offsets the insurer’s retained exposure above the cap.
