Definition. Short Rate is a non-pro-rata cancellation formula where the carrier keeps MORE than pro-rata — penalizes the insured for cancelling mid-term.

Also known as: Short Rate Penalty

Typical short rate factor: 90% of unearned (rather than 100% pro-rata). For a $12K policy cancelled at 6 months, pro-rata refund = $6,000, short-rate refund = $5,400. Less common today than pure pro-rata cancellation.

Real-world scenario

Cedar Ridge Roofing LLC bought a 12-month general liability policy with a $1,000,000 per-occurrence limit, a $2,000,000 aggregate, and a $2,500 deductible. The annual premium was $8,400, which the owner financed through a premium finance agreement with a $1,680 down payment and nine monthly installments of $792. Five months in, Cedar Ridge landed a large commercial contract that required a different carrier, so the owner asked to cancel the existing policy early.

Because the insured requested the cancellation, the carrier applied short rate rather than pro rata. On a straight pro-rata basis the carrier had earned $3,500 for five months of coverage, so the unearned premium would have been $4,900. Under the short-rate table the carrier retained an extra penalty of $490 (roughly 10% of the unearned amount), so the actual return premium dropped to $4,410. Because Cedar Ridge had financed the policy, that $4,410 refund went first to the finance company as loss payee: after it deducted a $175 cancellation fee and applied the balance against the $3,960 still owed on the loan, the roofer received just $275 back instead of the $765 a pro-rata refund would have returned.

Had the carrier cancelled the policy instead — for example after a $1,900 premium-audit shortfall went unpaid — the refund would have been calculated pro rata at the full $4,900, about $490 more than the short-rate result. On a hypothetical $250,000 liability claim with $60,000 in legal defense costs the cancellation math would be irrelevant, but for a clean early cancellation on an $8,400 policy the short-rate penalty cost Cedar Ridge real money.

How it affects your premium

Short rate is not a coverage you buy; it is the penalty formula a carrier uses when you cancel mid-term. How much it costs depends on several factors:

  • Who initiates the cancellation — Insured-requested cancellations trigger short rate, while carrier-initiated cancellations for nonpayment or nonrenewal are usually refunded pro rata (no penalty).
  • How early in the term you cancel — The short-rate penalty is largest early in the policy period and shrinks as more premium becomes earned premium, disappearing near expiration.
  • Any minimum earned premium clause — Policies with a minimum earned premium (common on E&S, builders risk, and specialty lines) can retain 25% or more regardless of cancellation date.
  • The size of the annual premium — The penalty is a percentage of the unearned portion, so a $50,000 policy produces a far larger dollar penalty than a $2,000 one.
  • Short-rate table vs. flat percentage — Some carriers use a filed short-rate table; others apply a simple 10% haircut on the unearned premium.
  • Premium finance involvement — Finance-company cancellation fees and interest already accrued reduce your net refund on top of the short-rate penalty.
  • State regulation — Several states cap or prohibit short-rate penalties on certain personal and small commercial lines, forcing pro-rata refunds instead.

Common misconceptions

Myth: Short rate and pro rata mean the same thing.

Reality: They do not. Pro rata refunds the exact unused portion of premium, while short rate keeps an additional penalty on top, leaving you with a smaller return premium.

Myth: If the insurance company cancels my policy, I get hit with the short-rate penalty.

Reality: No — carrier-initiated cancellations (for example, a nonpayment cancellation) are almost always refunded pro rata. Short rate applies only when the insured requests the cancellation.

Myth: Short rate lets the carrier keep whatever it wants.

Reality: The penalty follows a filed short-rate table or a stated percentage, and it applies only to the unearned premium, not the entire policy amount.

Frequently asked questions

Why am I being charged a short-rate penalty when I cancel my policy early?
Because you initiated the cancellation, the carrier is allowed to keep a small penalty on top of the earned premium to offset its up-front acquisition and administrative costs.
How do I avoid a short-rate penalty?
Let the policy run to its expiration date and simply non-renew, or check whether a deposit premium or minimum earned clause already dictates the refund. Many carriers also cancel pro rata if you replace the policy with them.
How is the short-rate refund calculated?
The carrier first determines the pro-rata unearned premium, then subtracts the short-rate penalty (often 10% of that unearned amount or a figure from a filed short-rate table) to arrive at your return premium.
Does short rate apply if the carrier cancels me for nonpayment?
No. A carrier-initiated cancellation is refunded pro rata, so you keep the full unused portion of premium with no penalty.
Will a minimum earned premium change my short-rate refund?
Yes. If your policy has a minimum earned premium, the carrier can retain that floor amount regardless of the short-rate calculation, which sometimes leaves you with an even smaller refund.
