An SR-22 is a state-filed certification that proves you have in force the required insurance coverage, and it is not the actual underlying insurance policy or coverage. As such, your cost for the filing itself is limited to any filing fees charged in your state by your insurance company. These fees may vary by state and are usually $25 or less per filing. You'll still have to pay for your underlying auto liability insurance coverage, though, and you may face additional costs due to your traffic violation. Sometimes states charge a license reinstatement fee if your license has been suspended, and fines and penalties for driving without insurance in the first place. But these costs are not directly related to the SR-22. They are the result of the traffic violation that led to you needing an SR-22 in the first place.
