When you’re looking to insure your car, you want to know that you’re getting the best deal. To know this, you’ll probably look at the average cost of insurance and try to make sure you’re being offered rates on the lower end. But knowing the average cost of auto insurance can be a little tricky.

What Determines the Average Cost of Auto Insurance

The average cost of auto insurance varies depending on a wide number of factors.

These include:

  • Age: Drivers on either end of the age spectrum are typically charged higher premiums.
  • Gender: 48% of Americans think auto insurers charge men more for coverage than women, but it depends on the insurance company regarding how they think gender impacts risk.
  • Location: The average cost of car insurance varies by state and city inside the state.
  • Insurance provider: All things being equal, different providers may offer different rates. Some can offer discounts, whereas others may determine you to be a higher risk.
  • Driving history: The cleaner your driving record, the lower your premiums will likely be.
  • Credit score: Not all states allow insurers to look at credit scores, but in the ones that do, insurance companies may consider lower scores to be higher risk and raise the premiums accordingly.

Average car insurance cost by the company

Each car insurance provider has its criteria for determining car insurance premiums. Insurance companies may often agree, like how teenagers typically pay more for car insurance across the board. 

Other times, like in the case of gender, there does not seem to be a consensus. Different companies use different criteria, which may be reflected in the differences in rates offered to the same person. Shop around and compare various companies to get cheap car insurance rates.

Car Insurance Rate FAQs

How much does car insurance cost for a beginner? 

This depends on how old the beginner driver is. Teenagers will have higher premiums than new drivers over the age of 25. It also depends on what kind of coverage you’re looking for. Compare providers to find the best value coverage for your situation.

Paying off your car loans doesn’t directly affect your car insurance rates. However, it can improve your credit score. Better credit scores allow insurance providers to recalculate your risk level, leading to lower car insurance premiums. 

Also, once your car loan is paid off, you can lower your insurance coverage to liability only, lowering your rates. Remember that liability-only insurance does mean repair and replacement to your car aren’t covered if you have a loss.

Does it cost more to insure a red car?

No. This is a common misconception that has been circulating for many years. Unless it’s a fancy custom color that could be considered an extra modification to the car, it doesn’t matter what color car you drive. It won’t impact your insurance rates.

What’s the average car insurance cost for a teen driver?

According to the Centers for Disease Control and Prevention (CDC), teens are more likely than older drivers to underestimate or not be able to recognize dangerous situations.

The average monthly premium can range from around $300 to as high as over $700 more to insure your teen. Adding a teen to your existing policy can increase the average household’s car insurance bill by 152%.

How does my age affect my car insurance rates?

Usually, the younger you are the higher your rates will be, with insurance rates settling around age 25. Drivers over the age of 80 will see their premiums increase again.

Finding Good Car Insurance Rates

The average cost of car insurance varies dramatically depending on many factors. Knowing if you’re getting a good deal on your insurance policy can be complicated, so you must shop around to ensure you’re getting the most affordable insurance available.
