MoneyGeek gathered average rates for auto insurance in Naperville for a sample 40-year-old male driver with full coverage, per our methodology.

A full-coverage policy provides you with more protection but is usually more costly than state minimum insurance. Full coverage includes:

  • Collision Insurance: Pays for damage to your vehicle due to a collision with another vehicle or stationary object
  • Comprehensive Insurance: Pays for damage due to non-collision-related incidents such as vandalism or theft.

If you have an older vehicle, a full coverage policy may cost more than your car is worth to insure. In that case, you may want to opt for a liability-only or state minimum policy instead.

Cheapest Car Insurance in Naperville for Minimum Coverage

The cheapest car insurance options in Naperville for state minimum policies are:

  • Mercury: $325 per year
  • GEICO: $334 per year

In Naperville, a minimum coverage policy is the most affordable option. However, since it does not include comprehensive and collision insurance and has low levels of liability coverage, you won’t have full protection.

Look at the table below to compare coverage levels and costs.

Cheapest Minimum Liability Car Insurance in Naperville
State Minimum

A state minimum policy may be the most budget-friendly choice in Naperville, but it offers the least protection. In Illinois, a minimum coverage policy has 25/50/20 liability limits. In addition to this, all Illinois drivers are also required to have uninsured/underinsured motorist coverage.

Lower coverage limits may leave you on the hook for damages after a crash. For example, if you are responsible for medical expenses of $85,000 for another driver, but your policy covers only $25,000 in bodily injury liability because you opted for the Illinois state minimum, you would have to pay the remaining $50,000 out of your pocket.

Illinois Minimum Liability Requirements

  • Item
  • Bodily Injury and Property Damage
    $25,000 per person, $50,000 per accident and $20,000 for property damage. A more protective level is 100/300/100.
  • Uninsured Motorist
    $25,000 per person and $50,000 per incident. The minimum coverage may not be enough if you're in a serious accident.

Based on our findings, State Farm ties with Erie as the cheapest car insurance provider in Naperville. State Farm customers pay an average of $723 per year for full coverage. The insurer also has the second-highest customer satisfaction rating and offers rideshare insurance, which most insurance companies do not always offer, as an optional coverage.

More About State Farm

By adding rideshare coverage, the medical, emergency roadside assistance and rental car reimbursement coverages in your personal auto policy remain in effect when you’re working for a ridesharing company. It also extends those coverages when your app is on and you're available for hire. Once you match with or are actively driving a passenger, all coverages except liability insurance remain. State Farm also offers more common add-ons. One is rental car or travel reimbursement coverage, which provides a $500 repayment of your deductible if you are involved in an at-fault accident in your rental car. Another is roadside assistance which pays for towing costs and more if you break down.
