DUI Cost Calculator
Estimate the total financial impact of a DUI/DWI, including fines, legal fees, and years of higher insurance premiums.
⚠️ This is a rough educational estimate only, not legal advice. Actual DUI costs vary significantly by state, county, blood alcohol level, prior record, and whether the case goes to trial.
How much does a DUI actually cost?
A DUI conviction rarely ends with just a fine. The court fine itself — commonly $500 to $2,000 depending on the state — is often the smallest piece of the total bill. Add a private attorney (frequently $2,000-$5,000, though a public defender may be available at no cost if you qualify), a mandatory DUI education or treatment program, license reinstatement fees, and possibly an ignition interlock device, and the immediate out-of-pocket cost alone can exceed $5,000-$10,000 for a first offense — before counting lost wages or increased insurance.
Why insurance costs are the hidden long-term expense
The most underestimated cost of a DUI is the multi-year increase in auto insurance premiums. Most states require an SR-22 filing (proof of financial responsibility) for around three years after a DUI, during which insurers classify you as high-risk and raise premiums substantially — often by hundreds of dollars per year, compounding over the SR-22 period. Repeat offenses escalate every component: fines, mandatory jail or probation, program length, and interlock requirements all increase with a second or third offense, which is why this calculator scales costs with an offense-severity multiplier.
What determines your actual cost
Your real cost depends on your state's specific fine schedule, whether you hire a private attorney or use a public defender, your prior record, and whether your state or judge requires an ignition interlock device (increasingly common even for first offenses in many states). This calculator provides an illustrative, educational estimate based on typical national averages — it is not legal or financial advice. If you are facing a DUI charge, consult a licensed criminal defense attorney in your state, since the legal and financial stakes are significant.
Frequently Asked Questions
How much does a first-offense DUI typically cost?
Including fines, a possible attorney, DUI school, license fees, and three years of higher insurance, a first offense commonly totals somewhere between $7,000 and $15,000 as an illustrative estimate. The exact amount depends heavily on your state, whether you hire a private attorney, and your insurance company's rate increase.
Why does a second or third DUI cost so much more?
Repeat offenses trigger steeper mandatory fines, longer required DUI programs, longer license suspensions, higher insurance surcharges, and a much greater likelihood of a mandatory ignition interlock device — all of which compound on top of each other, often multiplying the total cost of a first offense by roughly two to three times.
Do I need a private attorney for a DUI, or is a public defender enough?
Public defenders are qualified attorneys and can be a solid option if you qualify financially, but caseloads are often heavy. A private DUI attorney typically costs more but may offer more individualized attention. Whether that trade-off is worth it depends on the specifics of your case — consult a local criminal defense attorney to decide.
How much does a DUI raise my car insurance?
Many drivers see their premiums increase by several hundred dollars per year for roughly three years, since insurers classify a DUI as high-risk and most states require SR-22 proof-of-insurance filings during that period. The exact increase depends on your insurer, state, and driving history.
What is an ignition interlock device and do I have to pay for it?
An ignition interlock device is a breathalyzer wired into your vehicle's ignition that prevents starting the car if alcohol is detected. Many states require it after a DUI, even for first offenses in some jurisdictions, and the driver is typically responsible for installation and monthly rental costs, often around $1,000-$1,500 per year.
Is DUI school or an alcohol education program mandatory?
Most states require completion of a DUI education or treatment program as a condition of sentencing or license reinstatement. Program length and cost typically increase with repeat offenses, and you are usually responsible for paying the program fee yourself.
Are there costs this calculator doesn't include?
Yes. This tool does not include potential costs like towing and vehicle impound fees, bail, lost wages from court appearances or jail time, or civil liability if the DUI involved an accident. Those can add substantially to the total in more serious cases.
How accurate is this DUI cost estimate?
This is a rough, educational estimate based on typical national averages, not legal or financial advice. Actual DUI costs vary widely by state, county, blood alcohol content, prior record, and case outcome.
