What the Illinois numbers actually mean
- The legal minimum in Illinois is 25/50/20 (bodily injury per person / per accident / property damage, in thousands). That is a floor set by statute, not a recommendation — it is the least cover you can legally buy, not the amount that protects your assets.
- Illinois is an at-fault (tort) state: the driver who caused the crash is legally responsible, and an injured party can pursue them directly — including personally, above their insurance limits.
- A 2026 full-coverage policy in Illinois averages about $2,578 a year, 12% above the national average. Note that this is a different measure from the NAIC expenditure figure above — one is a quoted premium, the other an average spend per insured vehicle.
- Motorcycle liability insurance is required in Illinois.
What makes Illinois different
Illinois is an at-fault state with relatively low statutory minimums, which produces a specific and predictable problem: a driver who buys only the legal minimum can cause an injury that exceeds their coverage in the first serious crash, and the injured party can pursue them personally for the difference. That is why uninsured/underinsured motorist coverage and a personal umbrella policy matter more here than the minimums suggest.
The auto market itself is dominated by the Chicago metropolitan area, where traffic density, repair costs and theft rates sit well above the rest of the state. A driver in downstate Illinois can pay materially less than the state average, so a statewide figure is a poor guide for an individual quote — the Chicago-versus-downstate spread is one of the widest of any state.
Homeowners insurance in Illinois is primarily a severe-convective-storm market. Hail and wind claims, particularly on older roofs, drive both the frequency and the severity of losses, and carriers have tightened roof-scheduling and age-of-roof underwriting in response. If your roof is more than fifteen years old, expect that to be a live question in the underwriting conversation regardless of what the state average says.
Watch out: The Chicago area and downstate Illinois are effectively two different insurance markets. Get a quote for your actual ZIP code before you compare yourself to the state average.
Illinois rules that change what you should buy
- Minimum limits (25/50/20) are a legal floor. In an at-fault state there is no such buffer: the injured party can sue you directly, and a judgment above your limits is enforceable against your income and assets.
- Compare quotes at identical limits. Most of the price difference between two "cheap" quotes is a difference in coverage, not in efficiency. Write down the limits and the deductible before you compare the premium.
- Motorcycle coverage is separate. A motorcycle policy in Illinois does not inherit your auto policy's limits or discounts, and riders are typically rated on engine size, experience and bike type rather than on the same factors as a car.
- The home figure on this page is a model, not a rate. Where a current published state average is not available, we escalate the most recent published figure and label it. Treat it as an order of magnitude, not a quote.
Why Illinois costs what it does
- Chicago urban congestion
- Hail and tornado exposure
- Moderate litigation
Additional note for Illinois: At-fault; mandatory UM/UIM 25/50.
Where to check Illinois's rules yourself
Auto and home insurance in Illinois are regulated by the state insurance department, which licenses carriers, reviews rate filings, and handles consumer complaints. If you have a dispute with an insurer, that office is your official recourse — and its published rate filings are the fastest way to see what is happening to premiums in the state.

How does Illinois compare nationally?
Illinois sits close to the national average for both auto and home, with Chicago-area urban rates above downstate levels.
What is the average auto insurance cost in Illinois?
A 2026 full-coverage policy in Illinois averages about $2,578 a year. Separately, the NAIC 2023 expenditure measure — average spend per insured vehicle, which is not the same thing — is $2,103 for Illinois, against a national average of $2,308.
How much is home insurance in Illinois?
The Insurance Information Institute (Triple-I) 2021 average HO-3 premium for Illinois is $1,223. InsurTool models the current figure near $1,770 by escalating that 2021 number by roughly 45% (reinsurance costs and climate-driven losses); the 2021 figure is shown alongside it because the escalation is our model, not a filed rate.
Does Illinois use credit history to set insurance prices?
Credit-based insurance scoring rules are set state by state, and the answer changes the price for anyone with a thin or damaged credit file. Illinois is covered in our credit-based insurance score guide, which lists which states restrict or prohibit the practice.
How can I get a more accurate quote?
Compare at least three quotes from licensed insurers using the same coverage limits and the same deductible. A quote is only comparable if the limits match — most "cheaper" quotes are cheaper because they cover less.
What are the minimum liability limits in Illinois?
The legal minimum in Illinois is 25/50/20 (bodily injury per person / per accident / property damage, in thousands of dollars). Most experts recommend carrying well above the minimum — a serious crash can exceed it quickly, and in an at-fault state the injured party can pursue you personally for the difference.
Is Illinois a no-fault auto insurance state?
Illinois is an at-fault (tort) state: the at-fault driver's liability insurance pays for injuries and damage.

On the two auto figures. The NAIC expenditure figure is average spend per insured vehicle across the state; the quoted full-coverage figure is an average premium for a specific coverage package. They are not interchangeable and they will not match. Where a figure is a model rather than a published number, it is labelled as an estimate on the card above.
