Definition:General aggregate limit
📋 General aggregate limit is the maximum total amount an insurer will pay for all covered claims under a single policy during a defined policy period, typically one year. Unlike a per-occurrence limit, which caps the payout for any individual event, the general aggregate limit sets a ceiling on the cumulative liability the carrier assumes across every claim that falls within the policy's scope. It is a central feature of commercial general liability policies and plays a critical role in how underwriters structure coverage and manage loss exposure.
⚙️ When an insured experiences multiple claims during the policy period, each approved claim erodes the general aggregate. Once the cumulative payouts — including defense costs, where applicable — reach the aggregate ceiling, the insurer's obligation to pay further claims ceases, and the policyholder bears the remaining exposure. For example, a contractor with a $2 million general aggregate and a $1 million per-occurrence limit could exhaust coverage after just two maximum-severity incidents. Brokers and risk managers monitor aggregate erosion closely, sometimes arranging excess or umbrella layers to provide additional capacity once the primary aggregate is depleted. Some policies offer aggregate reinstatement provisions, though these typically come at additional premium.
💡 Understanding the general aggregate is essential for both buyers and carriers because it defines the true boundary of protection a policy offers. A low aggregate relative to the insured's risk profile can leave significant gaps — a reality that becomes painfully apparent in high-frequency loss scenarios such as product liability or construction defect claims. On the carrier side, actuaries and underwriters use aggregate limits to model worst-case portfolio exposure and set appropriate reinsurance attachment points. Regulators and rating agencies also scrutinize how aggregate limits are managed across a book of business as a measure of an insurer's capital adequacy and disciplined risk selection.
