Short-rate cancellation
A cancellation method that returns less than the full unused premium when you end a policy early, so the insurer keeps a penalty on top of what it earned.
Also called: short rate, short-rate penalty, short-rate refund
Short-rate cancellation applies a penalty when the policyholder, not the insurer, ends a policy before its expiration date. The insurer refunds the unearned premium at a reduced rate, using a short-rate table or a flat penalty, commonly around 10% of the unearned amount. The reasoning is that early cancellation costs the company the up-front expense of writing the policy. When the insurer cancels, or the policy calls for pro rata cancellation, no penalty applies.
Say your annual premium is $2,000 and you cancel with 185 days left, so the unearned premium is about $1,014 (hypothetical). A pro rata refund is $1,014. With a 10% short-rate penalty, the refund is about $912 and the insurer keeps roughly $101 more. The standard ISO homeowners form (HO 00 03) refunds pro rata when a policy is canceled, but insurers file their own wording and state amendatory endorsements vary. Florida's rules, for example, bar short-rate tables that return less than 90% of the pro rata amount unless the insurer justifies them.
Before you cancel, read the cancellation section of your policy and ask the insurer to show the refund calculation in writing. A mid-term switch to a new insurer can cost you the penalty. Ask whether waiting until renewal avoids it. See the canceling guide and the cancellation entry.
