Definition:Per-occurrence deductible
💰 Per-occurrence deductible is the fixed dollar amount an insured must absorb for each covered occurrence before the insurance carrier's payment obligation begins. Unlike an annual aggregate deductible, which accumulates losses over a policy period, the per-occurrence deductible resets with every qualifying event — meaning each hurricane, fire, or liability incident carries its own retention. This structure is standard across commercial property, general liability, and many casualty lines.
🔄 In practice, once a covered occurrence generates a loss, the insured pays the deductible amount first, and the carrier covers eligible costs above that threshold up to the applicable policy limit. If a windstorm damages three buildings owned by the same insured and those damages stem from a single weather event, one per-occurrence deductible typically applies to the combined loss rather than three separate deductibles — though the precise result depends on how the policy defines "occurrence." Disputes over whether multiple losses constitute one or more occurrences are among the most litigated issues in insurance coverage law, because the answer determines how many deductibles the insured must pay and how many limits the carrier must make available.
🎯 For underwriters, the per-occurrence deductible is a powerful tool for aligning the insured's skin-in-the-game with the carrier's risk appetite. A higher deductible reduces premium and filters out smaller losses that are expensive to administer, while a lower deductible shifts more first-dollar exposure to the insurer. Brokers often model deductible trade-offs alongside self-insured retention options to help clients optimize their total cost of risk. In reinsurance programs, the concept carries over — cedents retain a per-occurrence amount before their excess-of-loss cover responds, making this structure foundational to how risk is layered across the market.
