Raising liability limits from 50/100/50 to 100/300/100 adds about $67 a year on average in our Naperville 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. Progressive charges less for 100/300/100 than for 50/100/50 for our benchmark driver.
Not for our benchmark driver. Comparing the same insurers in the same Naperville ZIP codes, full coverage averaged $2,329 a year nine months earlier and $2,191 in rates as of Aug. 31, 2026, a 5.9% drop. Allstate’s Naperville average rose 1.4%, but Progressive’s fell 18.2%, Country Financial’s 8.8% and GEICO’s 5.8%. State Farm’s latest rates are from November 2025, so it’s left out of this comparison. Liability-only coverage at 20/40/15 limits fell 0.1%, led by GEICO, which cut its liability-only average 4.3%.
DuPage County averages about $187 a month for full coverage, the 45th-most expensive of the 83 Illinois counties we price, and Will County, which covers south Naperville, averages $194. Both cost far less than Cook County, at $230.
Nearby DuPage County towns are priced close to Naperville: Lisle averages about $182 a month, Wheaton $177 and Downers Grove $188. Prices depend on where in Illinois you live, not just on your car and driving record.

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.
Coverage requirements come from Illinois law and the Illinois Department of Insurance. We refresh these figures when new rate data is released.

The published 2026 statewide Illinois rate studies we reviewed are split between Travelers and GEICO as the cheapest for full coverage.
