One note on price: Not all insurers will quote based on what you’ll pay each month. Some might list the annual or even semi-annual cost of a policy. (Why? Who knows? Insurance will never get accused of being easy.) Point is, here, too, you’ll want to be sure you’re comparing apples to apples. (Prices vary widely enough where it’s easy to get confused on the actual price.) That way, you know what insurer is truly offering the best price.
That’s where car insurance companies come in. The 10 biggest car insurance companies in the United States are State Farm, Geico, Progressive, Allstate, USAA, Liberty Mutual, Farmers, Nationwide, Travelers, and American Family. Each car insurance company offers a similar product. You pay a set fee, called a premium, on a monthly, semi-annual, or annual basis. In return, you get a car insurance policy that provides you with car insurance coverage. That coverage pays for expenses related to your car in the event of a crash, theft, or natural disaster. Exactly which expenses are covered depends on the coverage you select and pay for. How much car insurance coverage you need depends on several factors, like the value of your car, the minimum insurance coverage required in your state, and any extra car insurance coverage you want.
Large insurance companies analyze a huge amount of customers’ personal data (like social media posts, credit scores, and even your web shopping habits). Then, they churn the data through a proprietary algorithm that estimates how likely you are to shop around or just renew your existing policy each year. By doing so, they can increase your premium just enough to raise their profit margins without attracting your attention and prompting you to shop for a new policy.
If you live in an area with unusual state regulations or heightened risk of weather-related claims, shopping car insurance options will be vital. Not every car insurance company offers policies in every state, which can make pricing less competitive. If you live in storm-prone states like Louisiana or Florida, you might find it harder to get a competitive rate.
Oh, there are a whole bunch. The big ones include good driver discounts (for going long enough without a moving violation); affiliation discounts (for belonging to a group, like AAA or AARP, that partners with the insurer); low-mileage discounts (for, you know, low mileage) and car safety feature discounts (for installing stuff like emergency break assistance or collision avoidance systems). You can find a full list of common car insurance riders and discounts here.
Because car insurance companies all offer a similar product and have similar business models, choosing the right car insurance company is all about finding the balance of coverage, cost, and customer service that’s right for you. Some auto insurance companies let you do almost everything online with no human interaction – from getting a free car-insurance quote to buying a policy to making a claim. Others use local agents who meet with you and walk you through the process. Some auto insurance companies also offer a wide range of insurance and financial products, including banking, so you can handle much of your personal business in one place. Car insurance discounts vary by company, as does each company’s online tools and mobile apps. Start by deciding how much car insurance you need. Next, compare car insurance rates from different companies. Then, find best car insurance company for you, based on your budget and the level of customer service you want.
Young drivers — aged between 16 and 25 — pay very high car insurance rates, with those aged 16-19 paying the most expensive premiums of all. Because of the risk presented by inexperienced drivers, teen drivers pay more than three times the national average for car insurance. In Tennessee, teen drivers pay insurance rates in line with the national average: $4,741 per year.

At its core, car insurance is a bet. You pay your premium, betting that if something happens to your car, you’ll get that money back to pay for repairs, medical bills, and other costs. The car insurance company takes your premium, betting that if you do have an issue with your car, the cost of paying for it will be less than the premiums they’ve collected from you and other policyholders over the years. Insurance companies do lose money on occasion. For example, when Hurricane Harvey hit Houston, as many as 500,000 total loss car insurance claims were filed in response to the damage. Those claims cost the insurance industry billions of dollars – money that could have otherwise been profits.
Modified Car Insurance: defined by many companies as being significantly altered in its engine, body, chassis or interior from its original condition, which can negatively or positively change the value; many insurers will not provide collectible coverage for these types of vehicles (for example, an antique car in which much of the stock equipment has been replaced or that runs on nitro fuel).
Car insurance rates vary greatly depending on age. Your risk profile as a driver will change throughout your life, so you may be eligible for discounts at some points in your life while other times you may see your car insurance premium increase. This is why you want to keep shopping for car insurance throughout your life so you ensure the best value.

A company that specializes in the most basic coverage options may have the cheapest auto insurance rates. However, they may also lack some customer service benefits of more established companies. These benefits may include 24 hour customer assistance and claims tracking. Consumers should always be aware of these trade-offs as they make their decision.
