Does Better Coverage Cost More in St. Louis?
Full coverage at 100/300/100 limits costs a little less on average than 50/100/50 in our St. Louis data: $2,908 a year compared with $2,957, with the same $500 deductibles. The full-coverage package doubles the per-person injury limit, triples the per-crash limit and doubles the property damage limit, and it raises uninsured and underinsured motorist coverage to 100/300. American Family, Safeco and Shelter charge less for 100/300/100 than for 50/100/50 for our benchmark driver.
Is Car Insurance Going Up in St. Louis?
Not for our benchmark driver. Comparing the four insurers that are in both sets of rates, in the same St. Louis ZIP codes, their full-coverage average fell from $3,696 a year nine months earlier to $2,967 in rates as of Aug. 31, 2026, a 19.7% drop. American Family’s St. Louis average fell 31.5%, Progressive’s 31.3% and Shelter’s 6.3%, but GEICO’s rose 1.4%. Safeco is new in our rates over the past nine months, so it’s left out, which is why these averages differ from the St. Louis average above. State Farm’s latest rates are from November 2025, so it’s left out of this comparison. Liability-only coverage at 25/50/10 limits fell 9.5%, led by American Family, which cut its liability-only average 18.8%.
Why Does Car Insurance Cost More in St. Louis?
St. Louis City averages about $273 a month for full coverage, the highest in our data, and St. Louis County averages $218, the third-highest.
West County costs much less: Ballwin averages about $187 a month and Chesterfield $194, while Florissant, in North County, averages $243. Missouri insurers group drivers into rating territories that are generally based on claims experience, according to the Department of Commerce and Insurance.

How to Lower Your Car Insurance Rate in St. Louis
- Compare Shelter, Progressive and Safeco first. Shelter has the lowest full-coverage average among the five major insurers we compared in St. Louis, about $203 a month, and Progressive and Safeco are effectively tied for next, at about $217 and $222 a month.
- Quote several insurers. Among the five major insurers we compared in St. Louis, the lowest and highest averages are about $89 a month apart for the same driver and car.
- Consider underinsured motorist coverage. Missouri requires uninsured motorist coverage, but underinsured coverage is optional, according to the Department of Commerce and Insurance. It pays when the driver who injures you has too little insurance.
- Compare at every renewal. Over the past nine months, American Family has cut its St. Louis average 31.5%, Progressive 31.3% and Shelter 6.3%, while GEICO has raised its average 1.4%, so the order in our table can shift.
- Ask about discounts and check your deductible. Many insurers lower rates for a clean driving record, paying in full or insuring more than one car, so ask which car insurance discounts you qualify for. Our full-coverage prices use $500 deductibles. A higher deductible lowers your premium but means you pay more yourself after a claim; see how your deductible works.
- Price a bundle. Pairing your auto policy with a home or renters policy usually earns a multi-policy discount. See home insurance costs in St. Louis, then compare free home insurance quotes.

How We Calculated St. Louis Car Insurance Rates
Insurers must file their rates and rating rules with each state’s insurance regulator. Quadrant Information Services uses those filings to calculate what each insurer would charge a specific driver, and InsuranceQuotes analyzes those prices. This page uses rates in effect on Aug. 31, 2026.
- Sample: 210 full-coverage premiums from five insurers across 42 St. Louis ZIP codes, plus the same number of liability-only and 50/100/50 premiums.
- Driver: a single 40-year-old driver, licensed 24 years, with good credit and no accidents or violations, driving a 2024 Toyota Camry LE they own, for personal use.
- Coverage: full coverage is 100/300/100 liability with $500 comprehensive and collision deductibles and 100/300 uninsured and underinsured motorist coverage. We also price 50/100/50 with the same deductibles, and liability-only coverage at 25/50/10 limits, with 25/50 uninsured and underinsured motorist coverage and no comprehensive or collision. Missouri’s minimum has been 25/50/25 since July 1, 2019, so our liability-only prices use lower limits than the law requires.
- Calculation: for each insurer we take its lowest eligible price in each ZIP code and average those prices across the ZIP codes. The overall average is the mean of every insurer-and-ZIP price. Monthly figures are annual premiums divided by 12 and rounded.
- Rankings: we name a cheapest insurer only where it’s priced in at least half the ZIP codes and its lead over the next insurer isn’t so wide that it looks like an outlier. Annual prices within 3% of each other are called effectively tied.
- Rate changes: we compare the same insurer in the same ZIP codes, for the same driver and coverage, in rates as of Nov. 30, 2025, and Aug. 31, 2026. Safeco isn’t in the November 2025 rates and State Farm isn’t in the August 2026 rates, so they’re left out of rate-change comparisons; the other four insurers are in both sets of rates. Rate-change percentages are calculated from the annual premiums shown; other percentages use the rounded monthly figures.
- Insurers marked *: priced from recent published Missouri rate studies, scaled to our benchmark driver. They aren’t included in our averages or rankings. The State Farm row shows its November 2025 rates, so it isn’t included in our averages or rankings.
- What this isn’t: a quote. These are modeled prices for one driver profile, calculated from insurers’ rate filings. Your price depends on your ZIP code, vehicle, driving record, coverage choices and discounts.
Coverage requirements come from Missouri law and the Missouri Department of Commerce and Insurance. We refresh these figures when new rate data is released.
