What is the average cost of car insurance in St. Louis County, MO?
From A Plus Insurance quotes (Apr 2024 – Apr 2026): the average monthly premium across all auto-related policies is about $164 and the median is about $127. Auto-liability averages $126/mo and full coverage averages $254/mo. Non-owner coverage averages $93/mo. These figures span all A Plus Insurance markets — your actual rate in St. Louis depends on your driver profile, vehicle, and coverage selection.
Which company is cheapest in St. Louis County, MO?
In our 2026 dataset, The General had the lowest average at ~$117/mo on 18 quotes. Dairyland averaged ~$140/mo on 25 quotes and National General ~$148/mo on 53 quotes. Progressive — our highest-volume carrier with 260 quotes — averaged $163/mo. Bristol West averaged $181/mo and Geico $187/mo. Gainsco averaged $410/mo, focused on the highest-risk market. The right carrier depends on your specific driving history and needs.
What are the minimum car insurance requirements in Missouri?
Missouri requires 25/50/25 liability coverage. Missouri also requires uninsured motorist coverage at 25/50/25. Always verify current requirements with your state DMV.
How much more is full coverage vs. liability in St. Louis County, MO?
Full coverage averages about $254/mo vs about $126/mo for liability-only in our 2026 dataset — roughly 102% higher, or a gap of about $128/mo ($1,536/year). Whether full coverage is worth it depends on your vehicle’s value, whether you carry an active loan, and your ability to replace the vehicle out-of-pocket if it’s totaled or stolen.
Does a DUI affect rates in St. Louis County, MO?
Yes. A DUI typically triggers SR-22 filing requirements and significantly increases premiums for 3–5 years regardless of county. A Plus Insurance works with carriers that accept high-risk drivers in St. Louis. See our SR-22 insurance page for details on the filing process and costs.
Is non-owner insurance available in St. Louis County, MO?
Yes. Non-owner quotes represent about 4.7% of our 2026 dataset (25 quotes averaging ~$93/mo). Non-owner insurance provides liability coverage for drivers who don’t own a vehicle but need protection when borrowing or renting a car, or to maintain coverage for SR-22 compliance.
How often should I shop for insurance in St. Louis County, MO?
Every 6–12 months, or after any significant life change — new vehicle, address change, ticket or accident, adding a driver, or paying off a car loan. In our 2026 auto-related sample, premiums ranged from about $6.25 to $1,565.50/mo — a wide range that shows how much individual profile and coverage choice affect your final rate. Call (888) 445-2793 and A Plus Insurance will compare multiple carriers for you at once.
How does St. Louis County differ from St. Louis city for insurance purposes?
St. Louis city and St. Louis County are legally separate jurisdictions in Missouri — an unusual arrangement that affects insurance rating. St. Louis city typically carries higher rates due to higher crime and accident density. St. Louis County suburbs tend to have more moderate premiums reflecting lower density and accident frequency. Our 2026 data shows liability averaging ~$126/mo and full coverage ~$254/mo across all markets.
Are renters policies available in St. Louis?
Yes. Renters quotes represent about 5.5% of our 2026 total (29 quotes averaging ~$17/mo). Bundling your renters and auto policies with the same carrier often unlocks multi-policy discounts that reduce your total monthly cost. Ask your A Plus agent about bundling options — it’s one of the simplest ways to lower your overall insurance spend.
