How This Calculator Works
Calculation methodology and assumptions
This calculator estimates auto insurance premiums in Illinois based on the statewide average of $1,153/year, adjusted for driver age, vehicle value, coverage level, driving record, credit score (where permitted by state law), annual mileage, and deductible. Actual rates vary by insurer, ZIP code, and individual profile; this tool does not model your exact ZIP code or Illinois's specific statutory minimum-liability limits.
Key State Information

Example Calculation
What does car insurance cost in Illinois?
A 35-year-old driver with a clean record and good credit insuring a 2023 Toyota Camry. Coverage: 100/300 bodily injury, 100K property damage, $500 deductible collision, $250 deductible comprehensive, plus uninsured motorist — a popular package for financed vehicles. Illinois's NAIC-reported statewide average expenditure (across ALL drivers, including minimum-liability-only policies, not just full coverage) is $1,153/year — a useful benchmark, but full coverage like this profile typically costs more than that blended average, since it includes higher-cost comprehensive and collision protection that liability-only drivers skip entirely.
Result: Statewide average expenditure (all coverage levels combined): $1,153 (Illinois) — about $96/month. This NAIC figure blends minimum-liability and full-coverage policyholders together, so a full-coverage quote for a specific driver and vehicle, like the profile above, commonly runs higher than this average. Rates vary roughly 130% (about 2.3x) between the cheapest and most expensive states (NAIC 2023: Florida $1,864.63 highest, North Dakota $807.77 lowest); Florida, Louisiana, and New York consistently rank among the most expensive, while Maine, Idaho, and Vermont are among the cheapest. Getting quotes from 3-5 insurers typically reveals a 30-40% price difference for identical coverage.
