How Much More Does Better Coverage Cost in Arlington Heights?
Raising liability limits from 50/100/50 to 100/300/100 adds about $71 a year on average in our Arlington Heights data, with the same $500 deductibles. That’s about $6 a month for double the per-person injury limit, three times the per-crash limit and double the property damage limit, and the full-coverage package also raises uninsured and underinsured motorist coverage to 100/300.

- Property damage liability of $20,000 per crash
- Uninsured motorist coverage of $25,000 per person and $50,000 per crash, for injuries

How to Lower Your Car Insurance Rate in Arlington Heights
- Compare Progressive and GEICO first. They have the two lowest full-coverage averages among the four major insurers we compared in Arlington Heights, about $98 and $154 a month.
- Quote several insurers. In our Arlington Heights data, the lowest and highest insurer averages are about $215 a month apart for the same driver and car.
- Ask about uninsured motorist property damage. Illinois insurers must offer it, with a deductible of no more than $250, and you can buy it with or without collision coverage. It pays for damage an uninsured driver does to your car.
- Compare at every renewal. Over the past nine months, Progressive has cut its Arlington Heights average 19.9%, Country Financial 8.6% and GEICO 5.8%, while Allstate has raised its average 1.3%, 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 auto 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 deductibles affect your rate.
- Insure your car and home together. A multi-policy discount is a common way to save, so check average home insurance rates in Illinois, and compare home insurance quotes alongside your car quotes. Renting? A renters insurance policy can qualify too.

How We Calculated Arlington Heights 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: eight full-coverage premiums from four insurers across two Arlington Heights ZIP codes, plus the same number of liability-only and 50/100/50 premiums.
- Insurer count: our Illinois averages come from four insurers, fewer than in most states, so they can move more when one insurer changes its prices. We publish them as calculated, without adjustment.
- 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 20/40/15 limits, with 20/40 uninsured and underinsured motorist coverage and no comprehensive or collision. Illinois’ minimum has been 25/50/20 since January 2015, 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. State Farm isn’t in the August 2026 rates, so it’s 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 published 2026 Illinois 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 Illinois law and the Illinois Department of Insurance. We refresh these figures when new rate data is released.
