After our analysis of 2,700 cities and 128 companies, we found that Erie was the most affordable major insurer in the country with an average yearly rate of $1,052 based on our sample driver - about 31% cheaper than the national average across every insurer. The very largest of the five is GEICO, the second largest auto insurer in the U.S. by market share.
Step 3: Review what you found. If you are able, print out the different quotes you obtained. Make sure all the information is accurate and comparable. See if there are any differences with added no-cost features. These may be the ultimate thing that you base your decision on. Also, check on the policy exclusions (items that are not covered under the policy).
In aggregate, our three most expensive cities in North Carolina ranked with a cost of car insurance that was 17% greater than the state mean. The average annual premium for these three cities was $946, which, while expensive relatively speaking in the state, actually fell on the cheaper side compared to other states the team has analyzed. These locations ranged vastly in size from populations of less than 5,000 to over 203,000.
Everquote  actually has two websites. One is a typical lead generation insurance site with quoting tools for auto, home and life insurance. The other, Everquote Pro, is for insurance agents—it provides a way for agents to sign up to receive information about visitors to the site who use the quoting tools. Everquote is rated 1.5 out of 5, and has 80 user reviews on BBB.org.
How it works: The quoting process was similar to that of other comparison websites, although it offered me the option of connecting my Google or Facebook account to speed up the process. After I entered the requested information, the Zebra announced that it had matched me up with nine possible discounts, although it warned that not every insurance company offered all of these discounts.
Since most people choose one of these large insurers, NerdWallet compared quotes from the five largest auto companies in ZIP codes across the country. Rates are for policies that include minimum coverage required in each state, plus collision and comprehensive coverage. Our “good driver” profile is a 30-year-old with no moving violations and credit in the “good” tier. Use the tabs to see rates for drivers with credit in the “poor” tier and those with one at-fault accident as reported to the insurer.

Because most forms of insurance are regulated at the state level, state legislation influences car insurance premiums. For instance, in Michigan, a no-fault state, state law requires an unlimited amount of Personal Injury Protection coverage, a requirement that increases the cost of car insurance. Although each state legislates insurance differently, auto insurance prices may vary on a zip code-by-zip code basis. Below is an analysis of the cheapest and most expensive states for car insurance (from The Zebra's State of Insurance study).


Example (Comprehensive): You park your car outside during a major hailstorm, and it's totaled. If you have comprehensive, we'll pay out for the full value of your car (minus your deductible amount). Example (Collision): You back out of your garage, hit your basketball hoop, and cause $2,000 worth of damage to your vehicle. If you have collision, we'll then pay for your repairs (minus your deductible amount).
