How to Cancel Car Insurance and Get Your Refund (Without a Gap in Coverage)
You found a better rate, sold the car, or are moving. Canceling the old policy is easy. Getting the full refund you are owed, and not leaving even a one-day gap, takes a little order. This guide is part of our car insurance life events series, and it picks up where the renewal jumped switch checklist leaves off.
Key takeaways
- The money you get back is the "unearned premium": the part you paid for days after the cancellation date.
- Pro-rata returns every unused day. Short-rate keeps a penalty. In Florida's rule and South Dakota's worked example, it is 10% of the unearned premium.
- State rules differ: South Dakota bans cancellation fees but allows short-rate; Florida lets insurers keep 10% of the unearned premium on a mid-term cancellation you request; Washington sets refund floors of 90% to 97%.
- Start the new policy first, then cancel the old one effective the same day.
- If you are not replacing the car's coverage, deal with the plates and registration before you cancel.
What is an unearned premium refund?
You prepay insurance for a term, usually six or twelve months. If you cancel partway through, the insurer has "earned" the premium for the days the policy was in force and has not earned the rest. The unearned portion is what can come back to you.
South Dakota's Division of Insurance publishes the arithmetic. For pro-rata, "divide the number of days the policy was not in force by the policy term," using 365 for a one-year term or 182.5 for six months, then multiply by the total premium.
Pro-rata vs short-rate: what is the difference?
Pro-rata returns the full unused share. Short-rate reduces that refund by a penalty. South Dakota's worked example shows a short-rate unearned factor of .7524 against a pro-rata factor of .836. That is 90% of the pro-rata share, so the insurer keeps 10% of what would otherwise come back.
Which method applies is set by your state's rules and your policy form. Here is what four states publish.
| State | Rule when you cancel mid-term | Source |
|---|---|---|
| South Dakota | Insurer "can not charge a cancellation fee," but "can calculate return premium short-rate if the insured cancels mid-term." If you replace coverage, cancellation "must coincide with the date of the new coverage." | SD Division of Insurance |
| Florida | Refund due within 30 days. Insurer "may retain 10 percent (short rate cancellation) of the unearned premium," except for a service member called to active duty, who gets 100%. 8% interest on overdue refunds. | FL Dept. of Financial Services, citing Rule 69O-170.010 |
| Washington | Private passenger auto refunds are "computed on a pro rata basis," with at least 90% of the first $100 unearned, 95% of the next $400, and 97% above $500. Paid within 30 days. | RCW 48.18.300 |
| North Carolina | A newly issued policy canceled on or before the premium billing due date gets a pro-rata refund, based on the quoted premium, if you gave accurate information and the insurer later calculated a higher premium. | 11 NCAC 04 .0433 |
Florida adds a timing limit: state law "prohibits you from cancelling an automobile policy during the first 60 days unless the vehicle is destroyed, the vehicle is sold, or replacement insurance coverage is obtained."
How much will I get back? A worked example
Say you paid $1,800 for a 12-month policy and cancel after 120 days. That leaves 245 days unused.
- Pro-rata: 245 ÷ 365 × $1,800 = $1,208.22
- Short-rate at 10% (the Florida rule and the South Dakota example): $1,208.22 × 0.9 = $1,087.40
- Washington minimum: 90% × $100 + 95% × $400 + 97% × $708.22 = $90.00 + $380.00 + $686.97 = $1,156.97
The insurer earned $591.78 for the 120 days you were covered (120 ÷ 365 × $1,800). The difference between pro-rata and short-rate in this example is $120.82.
If you paid monthly, the math is smaller because less is prepaid. Your refund covers only the unused part of what you actually paid. Florida also notes that if the premium was financed through a premium finance company, the refund goes to that company first, "which will delay receipt."
What order should I cancel in so I am never uninsured?
This is the part that costs people the most when it goes wrong.
- Buy the new policy and get its effective date and ID card. Do not cancel anything until the new insurer confirms coverage in writing.
- Cancel the old policy effective the same day the new one starts. South Dakota requires a replacement cancellation to "coincide with the date of the new coverage." Matching dates is the safe habit everywhere.
- Put the request in writing. Washington's statute says cancellation by the insured may be effected "by written notice thereof to the insurer." Ask for a cancellation confirmation showing the date and the refund amount.
- Watch for the refund. Florida and Washington set 30 days for a refund after you cancel. Note the date you sent your request.
- Check the DMV side. California's DMV says that if new insurance information reaches the DMV "within 45 days of the cancellation of the first policy, a notice will not be sent." Other states are stricter.
Plates before cancelling: If you are canceling because you no longer need coverage on a car you still own, do not start with the insurer. North Carolina says "canceling insurance before returning the license plate will result in a fine." New York says to "surrender your vehicle registration and license plates to DMV before your New York State coverage ends for any reason." Plates first, insurance second.
A gap of even a few days can show up later on quotes and at the DMV. Our guide to a car insurance lapse of a few days explains the penalties state by state.
What if the insurer is the one canceling?
Then the rules usually favor you. Florida says that when "an insurance company cancels a policy, any unearned premium must be returned to the insured within 15 days after the effective date of the cancellation," and the company "must refund 100 percent of the unearned premium."
If the cancellation is for a missed payment, the timeline is different and you may still be able to save the policy. See missed car insurance payment grace periods.
Can I cancel right after I buy a policy?
Sometimes, with limits. Florida blocks cancellation in the first 60 days unless the car is destroyed or sold, or you have replacement coverage. North Carolina protects you if the insurer quoted one price and then calculated a higher one after you bought: cancel by the premium billing due date and the refund is pro-rata, based on the quoted price, provided your rating information was accurate.
If you are switching because your renewal jumped, the comparison is the step that pays for all of this.

Frequently asked questions
Do I have to call to cancel, or can I just stop paying?
Stopping payment is not a clean cancellation. It can lead to a nonpayment cancellation and a coverage gap on your record. Washington's law describes cancellation by written notice to the insurer, and getting a dated confirmation protects you everywhere.
Is there a fee to cancel car insurance?
It depends on the state and the policy. South Dakota prohibits a cancellation fee but allows a short-rate refund. Florida allows insurers to keep 10% of the unearned premium on a mid-term cancellation you request. Washington requires pro-rata with small percentage deductions.
How long does a car insurance refund take?
Florida and Washington set 30 days after your cancellation request. Florida sets 15 days when the insurer cancels, with 8% interest on overdue refunds.
Does a service member get a full refund?
In Florida, yes, if the request is from a service member being called to active duty: the insurer "must refund 100%."
Should I cancel before or after selling my car?
After the sale is complete and, in states like North Carolina and Florida, after the plates are turned in or moved to another car. Keep the bill of sale; New York lists it as proof if the DMV later asks about a lapse.
