Wisconsin Car Insurance Calculator: Cost & Coverage

• Data source: Rates come from insurer filings sourced through Quadrant Information Services, the same data source carriers use for actual underwriting.
• ZIP-level tracking: Wisconsin rates are updated monthly and tracked by ZIP code. ZIP 53212 and ZIP 53221 are both in Milwaukee with different rates.
• Author and reviewer: Mark Fitzpatrick is a licensed Property and Casualty Insurance Producer who has spent nearly a decade analyzing insurer rate filings.
• Editorial independence: No insurance company partnership influences these recommendations. Carrier rankings are driven by data, not commercial relationships.

In Wisconsin, the cheapest full-coverage insurance company ($58 per month) and the most expensive ($165 per month) are $107 apart for the same driver on identical coverage, $1,284 per year. Two of the most competitive options confirmed in Wisconsin's market are Acuity and West Bend Mutual, Wisconsin-only regional carriers that don't appear on most national platforms. A driver who runs only a national comparison and misses them loses access to their pricing on every quote.

Travelers prices Wisconsin $19 per month below its own regional average, making it another carrier worth including specifically because of its Wisconsin pricing.

State Farm doesn't write standard auto policies in Wisconsin, so any comparison that includes State Farm is pulling rates from a company that won't insure you here. MoneyGeek's full Wisconsin carrier comparison includes these regional carriers alongside all available national options.

Your address directly determines your Wisconsin rate. The difference between Milwaukee's most and least expensive ZIP codes is $29 a month for minimum coverage, meaning a driver in Riverwest or Harambee ($72 a month) pays $29 more than a neighbor in the Greenfield Par/Layton Park neighborhood ($43 a month) for identical coverage without leaving the city.

Wisconsin insurers price by territory based on traffic density and claim history per Wisconsin's Office of the Commissioner of Insurance (OCI), and Milwaukee's territory carries a higher rate than Green Bay.

Wisconsin rates drop $147 a month between ages 18 and 19 — a $1,764 single-year change that is 5.4 times larger than the $27 drop at 25. Carrier choice adds even more to this equation: at age 19, the difference between the cheapest and second-cheapest insurer adds another $45 a month. Re-shopping for insurance when you turn 19 will get you a lower quote than re-shopping after you turn 25 (but it's still recommended).

Wisconsin's credit spread between poor credit ($249 a month) and good credit ($92 a month) is $157 a month. For drivers with poor credit, West Bend Mutual applies a 1.3x poor-to-good penalty compared to the market average of 2.7x — the lowest credit penalty among Wisconsin carriers. So if you're a Wisconsin driver with poor credit, West Bend Mutual should be the first place you go for a quote.  

What's unusual is that good credit averages $92 a month in Wisconsin while excellent credit averages $114, and that inversion holds at eight of 11 carriers. This could be because Wisconsin insurers assume drivers with excellent credit insure more expensive vehicles, or because a longer (but slightly lower) credit score is seen as more responsible than a newer credit history with a higher credit score. Getting quotes from the full panel of Wisconsin insurers is the only way to make sure you're not paying extra for having excellent credit.

Your Wisconsin rate rises at the first incident, including accidents you didn't cause. A not-at-fault accident adds $7 per month ($84 per year), a speeding violation adds $26 per month, an at-fault accident adds $49 per month and an OWI adds $74 per month ($888 per year).

For accidents and moving violations, reported crashes stay on your Wisconsin driving record for five years per the Wisconsin DOT, and most carriers apply surcharges for three to five years. Re-shop in month 37 after any non-OWI incident: that's when you've cleared the standard three-year lookback used by most Wisconsin carriers and can quote as a clean-record driver again.

Wisconsin uses OWI (operating while intoxicated) instead of DUI/DWI. A first-offense OWI stays on your Wisconsin driving record for life, and you'll have to file an SR-22 to reinstate your license. Post-OWI premiums range from $92 to $241 per month among Wisconsin carriers for the same profile (a $149-per-month spread), and the carrier that ranked third-cheapest on a clean record becomes the most expensive after an OWI. Re-shopping carriers immediately after an OWI conviction in Wisconsin is the most impactful rate action available for that profile, but try again after the three-year mark when some insurers no longer include an OWI in their lookback period.

Dropping from full coverage ($92 per month) to minimum coverage ($39 per month) saves $53 per month, but switching from the most expensive carrier to the cheapest saves $107 per month. The coverage drop is the more visible choice and the one most Wisconsin drivers make first, but it saves less than half what a carrier switch captures, and it removes financial protection to get there.

Wisconsin is an at-fault state with a 51% comparative negligence rule. Above your policy limit, the debt is yours. A two-car crash with two injured occupants at $30,000 each totals $60,000 in bodily injury, $10,000 above the per-accident minimum. The $636 in annual savings from dropping to the minimum won't offset a five-figure court judgment. Drivers with net worth above $100,000 should carry at least 100/300/100.

Wisconsin drivers have a 1-in-58 chance of a deer collision in any given year, placing the state in the top five nationally per State Farm's 2024–25 claims data. The average Wisconsin deer claim cost $5,355 in 2023, not including the deductible, according to Acuity Insurance's analysis of more than 7,500 Wisconsin animal collision claims.

At a $1,000 deductible, a deer strike nets $4,355 in covered damage on average: that is the figure to compare against your annual comprehensive premium when deciding whether to keep coverage on an aging vehicle.

Deer strikes are covered under comprehensive, not collision. At each renewal, divide your annual comprehensive premium by $4,355. If the ratio is close to one (meaning a single average strike would only slightly exceed what you're paying annually), comprehensive is worth keeping.

Wisconsin's 15,000 to 19,000 deer crashes per year per the Wisconsin DOT are not evenly distributed by season: risk peaks in November and October, when the rut pushes deer onto roads at dusk and dawn.

Bodily injury liability pays the medical bills, lost wages and legal costs of people you injure when you're at fault. Wisconsin's minimum is $25,000 per person and $50,000 per accident per the OCI. In Wisconsin's at-fault system, your BI coverage is the primary financial protection for injured parties. The 100/300 limit protects against crashes in which injuries exceed the $50,000 per-accident limit.

Property damage liability pays for damage you cause to other people's cars, buildings and property when you're at fault. Wisconsin's minimum is $10,000 per accident per OCI. Replacing a totaled midsize vehicle costs $35,000 to $50,000. The difference between what your policy covers and actual repair or replacement costs is your obligation in Wisconsin's at-fault system.

Uninsured motorist (UM) coverage pays your medical bills and repair costs when the at-fault driver has no insurance. Wisconsin law requires drivers to carry UM at $25,000 per person and $50,000 per accident. Despite state laws, the Insurance Research Council (IRC) found 15.6% of drivers nationally were uninsured in 2023. Underinsured motorist (UIM) is optional; if purchased, the minimum is $50,000 per person and $100,000 per accident. Getting UIM coverage is worth it in a state with so many uninsured drivers.

Collision coverage pays for damage to your car from a crash, regardless of fault. Comprehensive coverage pays for theft, fire, weather damage and non-collision losses. Wisconsin's OCI names deer strikes as a "relatively frequent accident" covered under comprehensive, not collision. Winter weather documented by NOAA adds hail, ice and flood risk. Lenders require both coverages on financed vehicles.

Gap insurance pays the difference between what your car is worth and what you still owe on the loan if it's totaled. Wisconsin's OCI confirms insurers pay actual cash value at loss, not the loan balance. On a $25,000 loan with $20,000 actual cash value, the insurer pays $20,000; the $5,000 difference is yours without difference coverage.

An SR-22 is a form your insurance company files with the Wisconsin DMV to confirm you carry active coverage. It is not a type of insurance; it is a certificate that proves a policy exists. Per Wisconsin's DMV, an SR-22 is required to reinstate your license after an OWI. Confirm additional requirements at the Wisconsin DMV before purchasing coverage. Drivers who do require it can compare Wisconsin SR-22 carrier pricing before choosing a policy.

Step 1: Get quotes from as many Wisconsin carriers as possible. The carrier difference in Wisconsin reaches $107 per month for the same driver. When you compare, don't use only national comparison platforms or you'll miss out on companies like Acuity and West Bend Mutual, which are Wisconsin-only carriers that most national tools exclude. Include GEICO, Travelers, Farm Bureau, Erie and West Bend Mutual in any Wisconsin comparison. Use MoneyGeek's guide to Wisconsin's cheapest car insurance companies; it includes regional carriers that most national tools exclude.

Step 2: Re-shop on the right birthday. The birthday that matters most in Wisconsin is the 19th, not the 25th. The 18-to-19 drop is $147 per month — 5.4 times the 25th birthday drop of $27 per month. Get fresh quotes on your 19th birthday, specifically from carriers whose young-driver pricing differs from their adult ranking.

Step 3: Shop carefully if you have Excellent credit. Good credit costs $92 per month in Wisconsin, while Excellent credit costs $114 per month. The $22-per-month Good-to-Excellent inversion is confirmed at 8 of 11 Wisconsin carriers. Shop carefully to make sure you're not being penalized for having excellent credit. If your credit score is poor, include West Bend Mutual; it applies the lowest credit penalty among Wisconsin carriers.

Step 4: Re-shop immediately after any violation, including not-at-fault. Wisconsin carriers surcharge not-at-fault drivers $7 per month ($84 per year). Re-quoting right after a not-at-fault incident, before the rate adjustment processes, gives you the best shot at finding a carrier without the surcharge. For post-OWI profiles, the OWI premium ranges from $92 to $241 per month among Wisconsin carriers. While re-shopping after an OWI, contact the Wisconsin DMV for how to file an SR-22 if required.
