Definition:Experience-rated
📋 Experience-rated describes an insurance pricing approach in which a policyholder's own loss history directly influences the premium charged, rather than relying solely on broad class rating averages. This method is most prevalent in commercial lines — particularly workers' compensation, general liability, and group health coverage — where individual accounts generate enough claims data to be statistically meaningful.
🔄 In practice, experience rating works by blending an account's actual loss record with the expected losses for its class, weighted according to the account's size and statistical credibility. Larger accounts carry more weight on their own experience because their data is more predictive, while smaller accounts lean more heavily on class averages. The result is an adjusted rate — or a modification factor such as the experience modification rate — that underwriters apply to the base manual rate. Some programs go further with retrospective rating, where premiums are recalculated after the policy period ends based on actual losses incurred, effectively making the policyholder a partial self-funder of its own risk.
💡 Experience-rated programs create a direct financial incentive for policyholders to invest in risk management and loss control, because every prevented or mitigated claim feeds back into lower future costs. This alignment of interests benefits carriers as well, since accounts that actively manage risk tend to produce more stable and profitable loss ratios over time. For brokers and MGAs, understanding the mechanics of experience rating is essential when advising clients — a well-timed safety initiative or a strategic approach to claims management can meaningfully shift a client's rating trajectory.
