Factor #1 — Where You Live

Where you park your vehicle each night will have a huge impact on how much you pay for automotive insurance. Just look at the chart below. We’ve calculated average rates for an average driver in the top 3 most expensive and the top 3 most affordable states. Circumstances such as population, number of accidents reported per year, and the cost of living will determine whether you live in an area that is safe or dangerous for the average motorist. And your insurance premiums will be higher or lower as a result.

Factor #2 — Credit History

One of the most important factors when it comes to determining your monthly premium has to do with your credit score. Also, to a lesser extent, something called your “insurance score” will apply as well. Insurance scores are calculated using factors that are relevant to how risky a driver you may be — such as past claims filed, payments made on time to other insurance companies, and your driving history. Other insurance agencies may delve all the way into your economic past and calculate your risk based on things that are less relevant. Be sure to ask your prospective insurance company whether they use your credit score or your insurance score to figure out how much to charge you for your monthly premium.

Factor #3 — Driving Record

Insurance companies take a look at your driving record because they believe that it is the biggest predictor of whether or not you will get into an accident (and need to file claims with them as a result). If you have filed several claims or received several driving citations in the past few years, then you will likely have to pay a higher premium than drivers with a clean record. Eventually, these blemishes will disappear from your record (usually after about 5 to 7 years) and you can look forward to a lower premium in the future – assuming you go that long without filing claims are collecting tickets, that is.

Factor #4 — Driving Experience

Practice makes perfect, and getting behind the wheel is no exception. The more driving experience you have, especially if you have a clean driving record, the less likely you are to pay expensive monthly premiums for your automotive insurance. This is why teenage drivers are usually charged insanely high rates for their car insurance coverage – it’s because their lack of experience makes them a risky investment. It’s a proven fact that most teenage drivers will get into an accident within their first year of driving, which means your insurance company has to charge them more in expectation of having to pay out expensive claims.

Factor #5 — The Vehicle You Drive

Yes, even the type of vehicle you drive can predict whether or not you may have to file a claim. It will also determine how expensive that claim may be. Things such as theft, a lack of safety features, and the overall cost to repair or replace your vehicle will all come into play when your insurance company decides how much to charge you for your monthly premiums. Obviously,  people who drive older, economically priced, less popular cars are least likely to file an expensive claim. And their monthly premiums will reflect that. But driving a shiny, new luxury vehicle which thieves like to steal will bump up your insurance premium significantly.

Minor Factors: Marital Status, Homeownership, Annual Mileage, and More

Minor personal circumstances, such as your marital status, owning a home, working a specific job, and your annual mileage will also have an influence on how much you pay for your car insurance premiums. Being married, owning a home, driving fewer miles than the average motorist, and working specific jobs (such as serving in the military or being a member of the union) will all help to lower your rate. Obviously, your monthly rate will be higher if any are all those factors that do not apply to you.

Regardless of your personal circumstances, you can still end up saving money on your car insurance by shopping around for the lowest rates.
