Earned versus unearned
In a simplified time-based model, premium attributable to elapsed coverage becomes earned, while the portion for future coverage remains unearned. The appropriate treatment depends on the insurance contract and accounting framework.
The NAIC glossary describes an unearned premium reserve as a liability associated with coverage extending beyond the statement date. The term should not be used as a synonym for overdue customer debt.
A simple example
Hypothetical example: A policyholder pays $1,200 for twelve months of coverage. Assuming straight-line earning and three completed months, $300 is earned and $900 remains unearned.
Actual earning patterns, effective dates, adjustments, and contract requirements may differ from this illustration.
Different from unpaid or unapplied premium
Unpaid describes an amount not collected. Unapplied describes received funds awaiting allocation. Unearned concerns coverage timing. One label cannot substitute for the others in collection reports.
Receiving the entire premium in advance does not mean the entire amount is immediately earned.
Cancellations and refunds
Cancellation can affect earned and unearned amounts. A refund is not automatically equal to the simple remaining time fraction; applicable law, policy terms, and permitted charges matter.
Finance teams should reconcile the calculation and obtain authorized review before quoting a refund.
