Short Rate Cancellation

Short rate cancellation retains a portion of the unearned premium beyond the pro rata amount as compensation for the insurer's fixed underwriting and administrative costs.

Definition

When a policyholder voluntarily cancels before the policy expires, many insurers apply a short rate calculation rather than returning the exact proportional premium. The short rate factor is typically set by a rate table or formula that charges roughly 10% more than the pro rata amount would retain — in effect, a penalty for breaking the 'term commitment.' For example, if pro rata would return $900 of an annual $1,200 premium after 90 days, short rate might return only $810–$850. The justification is that the insurer incurred full underwriting, commission, and policy issuance costs upfront regardless of when the policy terminates. Many states have curtailed or eliminated short rate penalties for consumer (personal lines) policies, restricting them largely to commercial lines. Always read the cancellation section of your policy to know which method applies before you shop for a better rate mid-term.
