What does "prorated" mean for an insurance refund?
It means the refund (or additional charge) is calculated proportionally to the amount of coverage time actually used versus the full policy term, rather than as a flat amount.
Estimate only · not a real refund calculation
Enter your total premium, policy dates, and the date coverage is canceled or changed to get an instant, illustrative estimate of a prorated refund or charge. This tool is meant to give you a starting number before you check your actual policy documents or call your insurer.
Estimate your prorated amount
How this estimate is calculated
By default, this calculator uses straight pro-rata proration: it counts the total number of days in your policy term, counts the number of days remaining after your cancellation date, and returns that same fraction of your total premium — for example, if 90 of 365 days remain, you’d get back 90/365 (about 24.7%) of what you paid. This is the simplest and most common way consumers think about a mid-term refund, and many insurers use it, particularly for policyholder-initiated cancellations in good standing.
Some insurers instead use short-rate cancellation, which returns less than the straight pro-rata amount by applying an additional penalty — the logic being that the insurer already incurred fixed costs (underwriting, commissions, administration) regardless of how long the policy stayed in force, so an early cancellation should not receive a full proportional refund. Short-rate tables vary by insurer and state and are not standardized, so this calculator’s optional short-rate toggle applies a flat illustrative percentage (default 10%) deducted from the pro-rata refund, rather than any specific insurer’s actual short-rate table.
This calculator also does not know whether your specific policy is fully earned, has a minimum earned premium clause, or carries policy or endorsement fees that are non-refundable regardless of cancellation date — all of which are common in real policies and can reduce your actual refund below either figure shown here.
Pro-rata vs. short-rate, in plain terms
Pro-rata cancellation means you get back exactly the fraction of your premium that corresponds to the unused fraction of your policy term — no more, no less. It is the most refund-friendly method for a policyholder and is common for lender-required or no-fault cancellations, such as when a lender pays off a loan and the associated insurance requirement ends.
Short-rate cancellation returns less than the pro-rata amount for the same unused period, because a penalty percentage (or a short-rate table keyed to how early in the term you cancel) is subtracted first. It is more common for policyholder-initiated cancellations mid-term, particularly on commercial or specialty policies, and exists specifically to discourage cancellation shopping and recover the insurer’s upfront costs.
Prorated insurance FAQ
Which method does my insurer actually use?
It depends on your policy, insurer, state, and why the policy is being canceled. Many personal auto and homeowners policies use pro-rata for policyholder-initiated cancellations in good standing; some commercial and specialty lines default to short-rate. Check your policy declarations page or ask your insurer directly.
Will I get a full refund if I cancel my policy?
Only if you cancel on the very first day of the term. Any cancellation partway through a paid term typically returns less than 100% of the premium, using either method described above.
Can I owe money instead of getting a refund?
Yes — if you are switching to a plan with a higher premium, extending coverage, or your insurer charges a short-rate penalty larger than the earned-premium credit, the "prorated amount" can be an additional charge rather than a refund. This calculator will show a negative or low result in that kind of scenario if you enter it that way.
Do fees reduce my refund?
Often, yes. Policy fees, endorsement fees, and minimum earned premium clauses are common in real contracts and are not modeled by this calculator — they typically reduce your actual refund below the pro-rata figure shown here.
Is a prorated refund the same as a full policy cancellation refund?
Not necessarily. Some insurers issue any refund by check or original payment method days or weeks after cancellation is processed, and financed policies may first apply a refund against any outstanding loan balance before paying you the remainder.
