Car insurance in Illinois costs about $201 a month for full coverage in 2026, or $2,406 a year, for a 40 year old driver with a clean record, according to InsuranceQuotes and Quadrant Information Services, using rates insurers filed with state regulators as of August 31, 2026. Other datasets put the same coverage between $99 and $205 a month, because they price different drivers, different limits, and different data. Chicago costs far more than the rest of the state, about $3,386 a year for full coverage against $2,461 statewide, per NerdWallet. This guide compares the datasets, breaks down Chicago versus downstate rates, and covers the new rate review law that takes effect in 2027.
Illinois is a useful case study in why a single average misleads. MoneyGeek puts full coverage at $99 a month, Insurify at $163, Insure.com at $162, and InsuranceQuotes at $201. The spread is not an error. MoneyGeek prices a lower limit profile, Insurify reports live quotes, and InsuranceQuotes prices filed rates for a 40 year old with 100/300/100 limits. The honest range for a typical full coverage policy is $162 to $205 a month, with lower limit policies available below that and Chicago policies above it.
How much is car insurance in Illinois in 2026?
Full coverage in Illinois averages $162 to $205 a month in 2026, or about $1,938 to $2,461 a year, across the four national rate studies that publish a statewide figure. InsuranceQuotes and Quadrant put it at $201 a month for a 40 year old with a clean record and 100/300/100 limits. NerdWallet puts it at about $205 a month. Insure.com puts it at $162 a month, and Insurify puts it at $163 a month. Minimum liability coverage runs $44 to $89 a month across the same sources, with the spread again driven by driver profile and limits.
| Source and date | Full coverage per month | Minimum or liability only per month | Driver priced |
|---|---|---|---|
| InsuranceQuotes / Quadrant, Aug 31 2026 | $201 ($2,406 a year) | $69 liability only | 40 year old, clean record, 100/300/100, $500 deductibles, 475 ZIP codes |
| NerdWallet, Sep 2026 | About $205 ($2,461 a year) | Cheapest from about $31 | Average driver profile |
| Insure.com / Quadrant, 2026 | $162 ($1,938 a year) | $44 ($527 a year) | Average driver profile, statewide |
| Insurify, Nov 6 2026 | $163 ($1,952 a year) | $84 ($1,005 a year) | Real time quotes, partner network |
| Freeway, Sep 2026 | $182 | $89 | Over 1 million actual policies purchased |
| ValuePenguin, Sep 2026 | $185 | About $67 state average | 30 year old male, full coverage study |
| MoneyGeek, Aug 2026 | $99 | $50 | Base profile, lower coverage limits |
Freeway deserves a note because its data is different in kind. It reports on more than one million actual policies purchased under real underwriting conditions, not quotes or estimates, and it puts full coverage at $182 a month and minimum liability at $89 a month. That sits in the middle of the range, which is where an actual buyer should expect to land. MoneyGeek at $99 a month is the low end for a low limit profile, and it is useful as a floor rather than as a typical price.
How much is car insurance in Chicago?
Chicago averages $3,386 a year for full coverage, or about $282 a month, per NerdWallet September 2026, against $2,461 a year statewide. That is a $925 a year gap for the same coverage. Freeway puts Chicago full coverage at $204 a month against $182 statewide, and minimum liability at $94 a month in Chicago against $89 statewide. MoneyGeek puts Chicago at $146 a month for full coverage against $99 statewide, a $47 monthly gap.
| City | Full coverage per month | Source |
|---|---|---|
| Chicago | About $282 ($3,386 a year) | NerdWallet, Sep 2026 |
| Chicago | $204 | Freeway, Sep 2026, actual policies |
| Chicago | $146 | MoneyGeek, Aug 2026 |
| Peoria | $99 | MoneyGeek, Aug 2026 |
| Champaign | $90 | MoneyGeek, Aug 2026 |
| Illinois statewide | $162 to $205 | Four national studies |
Chicago costs more because it has higher accident and theft rates than the rest of the state, denser traffic, and more expensive repairs. Champaign at $90 a month and Peoria at $99 a month show what downstate pricing looks like on the same MoneyGeek profile. A driver who moves from Chicago to Champaign saves about $56 a month on that profile, or $672 a year, before changing anything else. The lesson is the same as in every state: the statewide average is a blend of two different markets, and your city sets your price.
Which car insurance company is cheapest in Illinois?
The cheapest insurer depends on the study, which is itself useful information. InsuranceQuotes compared four major insurers and found full coverage averages from about $113 to $335 a month for the same benchmark driver. State Farm is the largest insurer in Illinois by market share, and Travelers, Erie, Auto-Owners, and GEICO are often the lowest priced, per a comparison of 2026 rate studies. Insurify lists Auto-Owners at $41 a month for liability only coverage in its low deposit table, which is the cheapest liability figure in its Illinois data.
The $113 to $335 monthly range across four insurers for the same driver is the most important number in this section. It means the carrier you choose can matter more than the city you live in. A Chicago driver with the cheapest carrier can pay less than a downstate driver with the most expensive one. Get quotes from State Farm, GEICO, Travelers, Erie, and Auto-Owners at the same limits, and include at least one company you have not used before, because each carrier prices the same risk differently.
What car insurance does Illinois require?
Illinois requires liability coverage of 25/50/20, which means $25,000 per person and $50,000 per accident for bodily injury, plus $20,000 for property damage. Uninsured motorist coverage of at least $25,000 per person and $50,000 per accident is also required. Illinois does not require personal injury protection, collision, or comprehensive coverage, so a liability only policy meets the law. Most drivers buy more than the minimum, because $25,000 in bodily injury coverage is not much if you cause a serious crash.
One detail to watch: InsuranceQuotes prices its liability only figure at 20/40/15 limits, which is below the Illinois legal minimum of 25/50/20. That figure is useful for comparing carriers, but it is not a policy you can legally drive on in Illinois. When you compare liability only quotes, confirm the limits are at least 25/50/20, or you are comparing a price for coverage that does not meet the law.
How credit affects your Illinois car insurance rate
Credit is one of the largest rating factors in Illinois, and the gap is stark. MoneyGeek reports that drivers with good credit pay $99 a month for full coverage while drivers with poor credit pay $298 a month, a $199 monthly difference that adds up to $2,388 a year for the same coverage. Illinois allows insurers to use credit based insurance scores, unlike California, Hawaii, Massachusetts, and Michigan, so a low score follows you into the premium.
The practical effect is that two neighbors with the same car, same age, and same driving record can pay wildly different rates. Improving a credit score is a slow process, but shopping carriers helps right away, because each insurer weighs credit differently. Some carriers price poor credit harshly, others barely move. If your credit is low, get quotes from five or six carriers instead of three, and ask each one how much of the quote is driven by credit.
What is the new Illinois rate review law?
Illinois signed a new rate review law in August 2026 that gives regulators more power to review auto insurance rate filings. The rules apply to rates filed on or after July 1, 2027, so 2026 renewals are not yet affected. The law matters for 2027 pricing, not for the quote you get today, and it is worth knowing about because Illinois has historically had lighter rate regulation than many states. A stronger review process does not guarantee lower rates, but it does mean future increases will face more scrutiny before they take effect.
Until the law takes effect, the market works the way it always has. Carriers file rates, the Department of Insurance reviews them under the existing rules, and your premium is set by your carrier, your city, your driving record, and your credit. Shop every year, because the carrier that was cheapest last year may not be cheapest this year, and the rate review law will not do the shopping for you.
A worked example: Springfield versus Chicago
Take a 40 year old driver with a clean record and good credit, driving a 2012 Toyota Camry, with 100/300/100 limits. In Chicago, NerdWallet puts full coverage at $3,386 a year, or about $282 a month. Downstate, MoneyGeek puts Champaign at $90 a month and Peoria at $99 a month for full coverage on its profile. Even using the statewide InsuranceQuotes average of $201 a month as the downstate proxy, the Chicago driver pays about $81 a month more, or $972 a year more, for the same coverage.
Now add credit to the example. A Chicago driver with poor credit pays about $298 a month on the MoneyGeek profile, against $99 a month with good credit. That is a $199 monthly gap, or $2,388 a year, inside the same city. Location and credit together explain most of the spread in Illinois premiums, and both are worth more attention than the brand on the policy. If you live in Chicago and your credit is weak, the two cheapest moves are to shop five carriers and to check whether a telematics program that prices on actual driving beats a credit based rate.
How to lower your car insurance in Illinois
Compare at least three carriers, and five if your credit is below average. The $113 to $335 monthly range across four insurers for the same driver shows that the spread between carriers is larger than the spread between most cities. Raise your deductibles from $500 to $1,000 if you can cover the higher out of pocket cost. Ask about telematics, low mileage discounts, bundling with homeowners or renters insurance, and good student discounts if you have a young driver on the policy.
Homeowners in Illinois face a different market. Homeowners insurance in Illinois covers Chicago and downstate pricing for a house, which pairs with this guide if you are bundling. For the national picture, how much car insurance costs per year puts Illinois in context, and car insurance in Texas shows a warmer, larger state with higher average rates. If you are buying minimum coverage, read California minimum car insurance requirements to compare another large state floor, keeping in mind that Illinois minimums are 25/50/20.
