What Will a OWI/DUI Cost You in Wisconsin?

A DUI (called an OWI in Wisconsin) can hit your wallet hard. Even a first offense can cost thousands of dollars once you add up all the hidden fees and penalties. If you’ve been charged or you’re just curious about what to expect, our Wisconsin DUI Cost Calculator can help you estimate the real cost.

This guide will walk you through the common expenses included in a DUI case and help you understand what each cost means.

Understanding the Cost Categories

Here’s a breakdown of each input in the calculator and why it matters:

Fines & Court Fees

Wisconsin law requires anyone convicted of an OWI to pay court-imposed fines and fees. For a first offense, this amount typically ranges from $150 to $800. Some counties may also charge additional surcharges, depending on the case.

Attorney Fees

Hiring an attorney is one of the biggest costs in a DUI case, but also one of the most important. Legal fees in Wisconsin can range anywhere from $1,500 to $4,000 for a first-time DUI, depending on how complicated your case is and whether you go to trial.

Alcohol Assessment/Treatment

If you’re convicted, the court will usually require you to undergo an alcohol and drug assessment. Based on the results, you may also be ordered to complete treatment or attend educational classes. These programs usually cost between $200 and $1,200.

Occupational License & Reinstatement Fees

Most people lose their license after a DUI conviction. To get back on the road legally, you’ll likely need to apply for an occupational license. Eventually, when you're eligible, there are additional fees to fully reinstate your driving privileges. Altogether, these fees average around $200.

Ignition Interlock Device (IID)

Wisconsin requires an ignition interlock device if your blood alcohol content was 0.15 or higher, or if it’s a repeat offense. This device prevents your car from starting if you have alcohol on your breath. You’ll have to pay for installation and monthly service, often totaling over $1,000 a year.

Increased Insurance Premiums

A DUI conviction almost always leads to higher car insurance rates. You may be required to file an SR-22 form and could face surcharges for several years. The total increase in premiums over three to five years is commonly between $2,000 and $6,000.

Total DUI Cost in Wisconsin

When you plug your numbers into the calculator, you’ll see the estimated total cost of your DUI case. This amount is a general projection and can vary depending on your county, background, and whether you face additional charges.

For many first-time offenders, the total cost is somewhere between $5,000 and $10,000, and often more for repeat offenses.

Why It Matters

A DUI can have lasting financial and personal consequences. Understanding the costs up front can help you make informed decisions about hiring a lawyer, seeking treatment, and navigating the court process.
