What’s the cheapest auto insurance company?

COUNTRY Financial is the cheapest auto insurance company, with an average monthly premium of just $60 for a liability-only policy.

In addition to your personal information, you’ll need your car’s VIN, mileage, make, and model in order to get a rate quote. If you currently have car insurance, you can use your current declarations page as a cheat sheet for your current coverage types and amounts so you can get a quote for a comparable level of coverage.

Top 5 largest car insurance companies

It may seem like you see an advertisement for a new insurance company every day. However, the list of car insurance companies that have withstood the test of time is much smaller. These companies have survived by changing their business models over time.

Liberty Mutual, for example, originally launched in 1912 to underwrite workers’ compensation insurance policies for businesses. GEICO famously started by serving government and military employees in 1936. But by 1996, Warren Buffet’s investment firm Berkshire Hathaway had purchased the company, and it now provides policies to the general public.

How Insurify rates insurance companies
Our editorial team spent more than 350 hours developing the Insurify Quality (IQ) Score and scoring insurance companies. The IQ Score objectively analyzes and calculates a score for insurers using more than 15 crucial criteria. The team weighted criteria by importance to the consumer — factors such as customer reviews and affordability influence the score more than availability and third-party ratings.

We rate each company on a 1-to-ten scale based on five categories: financial ratings, customer satisfaction, affordability, customer support and transparency, and availability. Insurify updates ratings once a year or as more recent information becomes available.
- Third-party financial ratings: Insurify uses data from AM Best, S&P, Moody’s, and more to compare insurance companies’ credit and ability to pay out future claims.
- Customer satisfaction: To calculate this score, Insurify analyzed more than 28,000 customer reviews across 155 car insurance companies. We also consider third-party ratings from J.D. Power, the National Association of Insurance Commissioners, and Trustpilot.
- Affordability: Our data scientists analyzed more than 90 million real-time auto insurance rates from our partners across the U.S., as well as available discounts, to calculate an affordability score.
- Customer support and transparency: This measures coverage options, ease of claims filing, and the insurer's transparency surrounding discounts, coverages, and claims process.
- Availability and reach: Insurify scores availability and reach by identifying the number of states in which insurers offer coverage and company size by market share.

The 5 cheapest car insurance companies

You’re required to purchase at least a minimum level of liability coverage in most states in order to legally drive. It’s a good idea to consider higher coverage levels if you have the budget for it, but you must meet your state’s liability minimums. The cheapest car insurance companies for liability-only coverage are COUNTRY Financial, NJM, and Auto-Owners, each with liability premiums of less than $100 a month.

Insurance Company	Average Monthly Quote: Liability Only
COUNTRY Financial	$60
NJM	$63
Auto-Owners	$76
USAA	$106
Erie	$107
