Pro Rata Cancellation

In a pro rata cancellation, the policyholder receives back a refund that perfectly mirrors the remaining policy time — no penalty is applied.

Definition

Pro rata cancellation is considered the fairer method for calculating premium refunds because it charges only for the exact days coverage was in force. For example, if your annual premium is $1,200 and you cancel after 90 days, the insurer retains $300 (90/365 × $1,200) and refunds $900. When an insurer cancels a policy mid-term for its own reasons (e.g., exiting a market or non-payment in some states), most state regulations require a pro rata refund as a consumer protection measure. In contrast, when a policyholder voluntarily cancels, the insurer may apply a short rate calculation instead. Always check your policy's cancellation provision before switching insurers mid-term, as the difference between pro rata and short rate can cost you meaningful money.
