It is important to factor in things like customer satisfaction and financial stability when comparing the top 10 auto insurance companies. J.D. Power releases a study each year that highlights how happy consumers are with their insurance company – those with higher scores have better customer satisfaction.
For financial stability, A.M. Best ranks companies on their ability to pay out claims – lower scores mean the company doesn’t have the best credit rating and may be less reliable for paying claims to their customers.
Our editor rating takes both metrics into account, but also includes things like discounts the company offers, types of insurance available, and overall cost.
Tips for Finding the Best Insurance Company for You
1. Shop around for coverage
As a general rule, you should get quotes from at least three different insurers before you purchase a policy. Comparison shopping is the best way to ensure that you find the best deal on coverage, and you should include a mix of national and regional insurers in your search.
2. Consider your individual needs
Some insurance companies offer more perks and coverage options than others, so it’s important to make sure that an insurer has all the features you need before signing on. For example, if you’re concerned about your vehicle’s reliability, you may want to go with an insurer that offers car repair insurance or roadside assistance coverage as a policy add-on in case of a sudden breakdown.
3. Factor in discounts
Most major insurance companies offer a wide variety of discounts to help you save on your premium. So, even if one insurer doesn’t offer the lowest base rate, their discounts might still make them the best option for you.
Some discounts, like multi-vehicle and multi-policy discounts, are often factored into quotes automatically. But you should see which additional discounts you can qualify for in the future. For example, most major insurance companies offer a defensive driver discount for policyholders who complete an approved course.
