Key Differences between Aggregate Limit and Per Occurrence Limit

Aggregate Limit

The aggregate limit in insurance represents the maximum amount an insurer will pay for covered losses or claims during a specific policy period. It caps the total indemnity, encompassing multiple claims, settlements, or occurrences. Once the aggregate limit is exhausted, the insurer is no longer responsible for covering additional claims during that policy term. This limit is distinct from per occurrence or per claim limits, providing an overall ceiling on the total payout. For example, in liability insurance, the aggregate limit ensures that the total payout for all claims does not exceed the specified amount, offering a crucial parameter for risk management and financial planning for both insurers and policyholders.

Features of Aggregate Limit:

• Total Loss Cap:

Represents the maximum amount the insurer will pay for all covered losses during the policy period.

Per Occurrence Limit

The per occurrence limit in insurance denotes the maximum amount an insurer is willing to pay for covered losses arising from a single event or occurrence. This limit applies to each distinct incident, and once reached, the insurer is no longer responsible for additional payouts related to that specific event. For example, in liability insurance, the per occurrence limit caps the total indemnity for bodily injury, property damage, or other covered liabilities resulting from a singular incident. It provides clarity on the maximum financial exposure associated with individual occurrences, offering a crucial parameter for risk management and financial planning for both insurers and policyholders.
