Cheapest car insurance rates by state and age

While many factors affect how much you pay for car insurance, location and age are chief among them. Location plays a major role in the cost of insurance. Our analysis found that rural states are more likely to have lower car insurance rates than congested states with large cities and suburbs.

When creating rates, car insurance companies look at the cost and frequency of claims in areas. Places with more crime, such as car thefts and break-ins, usually have higher rates than low-crime areas.

Your age also plays a role in how much you  pay for car insurance. Typically, inexperienced drivers pay more, which means younger drivers usually have higher rates than older drivers.

How age affects car insurance rates

Young drivers pay the highest car insurance rates because of their inexperience and greater risk of getting into accidents.

Car insurance companies want to reduce the number of claims paid out, so those in age groups that are considered the riskiest have to pay the highest rates.

As you spend more time behind the wheel, your rates will likely go down unless you file multiple claims. Once drivers get into their 30s and 40s, they should see their car insurance premiums drop.

Plus, as you age, you are eligible for auto insurance discounts that bring down rates. Car insurance discounts include bundling your home and car insurance, good driver, and loyalty when you stay with the same insurer for a long time.

Now, here's the bad news -- your rates will likely begin to increase again once you hit your senior years. Elderly drivers are considered riskier than middle-aged drivers. Older people's reaction times may slow, which can lead to accidents. That means higher car insurance rates for the older age groups.

Shopping for car insurance

No matter your location or age, it pays to shop around for car insurance. Insurers price the same policies differently based on their respective formulas. Each insurance company has a different algorithm that weighs risk factors. That's why costs vary and it's important to do a car insurance comparison before you buy.

For instance, one insurance company may charge a lot more if you get speeding tickets, while another may not raise rates that much. Another example is one insurer may charge higher rates for young drivers or motorists who live in cities, while another might give you a break.

It's a smart idea to get car insurance quotes from at least three car insurance companies every couple of years. Provide multiple insurers with the same request, including coverage levels, and let them compete against one another. Make sure you take everything into account, including loyalty discounts or new customer discounts, when making the decision as to the right car insurance company for you.
