In insurance, experience means the recorded claim or loss history of an insured, class of business, territory, producer, or book of business. In plain language, it is the past insurance performance that underwriters and actuaries use to judge future risk.
How insurers use experience
Experience can be measured in several ways, including:
- frequency of claims
- severity of claims
- loss ratio
- trend in results over time
- comparison of actual results against expected claims
The exact use depends on the context. An underwriter may look at an insured’s prior loss experience before quoting renewal terms, while an actuary may study territory or class experience to revise rates for an entire segment.
Why it matters
Experience drives many core insurance decisions:
- whether to renew or re-underwrite an account
- whether to increase, decrease, or stabilize rates
- whether a class is profitable enough to keep writing
- whether reserves or pricing assumptions need revision
Good experience can support favorable pricing or broader underwriting appetite. Adverse experience can trigger higher premium, tighter terms, or nonrenewal.
Practical example
A manufacturer has five years of very low claim frequency and severity under its commercial program. That favorable experience may help it negotiate renewal terms more effectively than a similar manufacturer with repeated large losses and poor loss-control results.
