What Factors Affect Car Insurance Rates for a Cadillac STS?

There are a multitude of attributes that insurance companies examine to determine how much they charge for a policy -- and each company uses a different method, so there's not one carrier that's the lowest for every STS driver.

The sections below show a lot of variables car insurance carriers use to calculate rates:

Vehicle Age

Vehicle Age Average Monthly Premium
Less than 1 YearNo Recent Models
2-3 Years$104
4-5 Years$47
6-7 Years$99
8-10 Years$86
11-14 Years$79
15 Years or Older$89

The Cadillac STS has been around for a while -- that means vehicle age can play a big role in what you end up paying for insurance. Normally, it costs more to insure newer cars because they're worth more, but as they get older, insurance costs will gradually go lower.

Since a new model has not been added to the market for at least 5 years, the STS won't really fit this trend. However, as you can see in the table above, the cheapest Cadillac STSs to insure are those that are 4 to 5 years old, while the most expensive models are STSs that are 2 to 3 years old, on average.

Your Age

Age Average Monthly Premium

How old you are makes a significant difference in how much you pay for auto insurance. Based on the information above, the youngest STS drivers pay more compared to drivers who have more experience on the road. In this case, drivers under 18 pay over three times as much as those 25 or older.

Auto insurance prices continue to decrease as you get older, with drivers aged 65 years and older making up the cheapest age group for the STS.

Your Gender

Gender Average Monthly Premium
Male$86
Female$79

You may not know, but car insurance is usually cheaper for women than it is for men. This is because women are less likely to get into collisions and get speeding tickets, which lowers the chances of an insurance claim. The Cadillac STS sticks to the norm, where women pay about 9% less than men monthly for auto insurance.

Where You Live

State Average Monthly Premium
California$47
Florida$121
Georgia$113
Illinois$48
New York$142
North Carolina$53
Ohio$50
Pennsylvania$58
Texas$61
Virginia$55

It may seem like common sense that factors like how old you are and what vehicle you drive play a role in your car insurance rates, but did you know that where you live can matter just as much? Since insurance is regulated on a state-by-state basis, premiums can vary quite a bit depending on what state you live in.

For example, the average Cadillac STS owner in New York pays around $142 a month for liability coverage, while on average, the same driver in California will pay less than half of that price. The chart shows average prices for the top 10 most populous states, just to give you a good idea of how much rates can change depending on where you live.

Cadillac STS Car Insurance Discounts

Whatever your car, your age, or your home state, it's always in your best interest to take advantage of as many car insurance discounts as possible when shopping around for a new policy.

Not every insurance company will offer the same discounts, but there are a few that are relatively common. These include things like:

  • Multi-policy discounts for bundling your home and auto policies with the same carrier
  • Vehicle safety discounts for having a vehicle with higher safety ratings or one with certain safety features (like anti-lock brakes or air bags)
  • Pay-in-full discounts for drivers who choose to pay their entire policy premium at once, rather than in monthly installments
  • Multi-vehicle discounts for having several cars on your auto policy

While these are just a few of the discounts auto insurance companies offer, there are countless other ways to save money on you monthly insurance bill. Sometimes, the best rates come from simply having a favorable insurance profile, which means having a clean driving record or not having any recent insurance claims.

Although you can't control every factor car insurance carriers look at to calculate prices (like some of the ones mentioned above), you can control some of them. Below are just a few of the variables you can use in your favor when it comes to cost savings:

Your Driving Record

Infractions Average Monthly Premium
1 Accident$97
Multiple Accidents$142
1 Ticket$85
Multiple Tickets$175

You've no doubt heard ads from insurance companies posting hefty savings for responsible drivers. It shouldn't come as a surprise that if you get into a collision or get a speeding ticket, auto insurance premiums will go higher. But exactly how much will these infractions cost you?

If you look at the table above, you'll see that accidents will usually cost STS drivers more than tickets, but both will result in higher than average rates. Cadillac STS drivers with a single ticket will pay an average of $85 per month, while drivers with one accident on their record pay about $97 every month (up $14 from the $83/mo. overall average). Drivers who have multiple violations of either kind will end up paying even more.

How Much You Drive

Annual Mileage Average Monthly Premium
0-2,500 Miles$80
2,501-5,000 Miles$76
5,001-7,500 Miles$72
7,501-10,000 Miles$84
10,000+ Miles$90

Another variable that plays a role in your insurance rates is the total amount of miles you drive. Those who drive less often have fewer opportunities to get into an accident, so they'll typically end up spending less on car insurance. Based on the table above, you can see that Cadillac STS owners who drive 10,000 miles or more pay $90 for auto insurance, while those who drive fewer than 2,500 miles a year pay an average of $80 monthly.

If you don't use your Cadillac STS that often, it may be worth considering usage-based or pay-per-mile insurance. With these kinds of plans, you pay a small base rate each month, with your final monthly bill being calculated based on how many miles you drove.

How Do Cadillac STSs Compare to Other Vehicles?

If you're thinking about making a Cadillac STS your next car, it might be helpful to do your due diligence. Car insurance is just one cost that comes with a new car purchase, but it's guaranteed to be one that's worth taking into consideration.

Check out the table below to see how the Cadillac STS stacks up:

Cadillac STS National Average
Liability Insurance$161$81
Full Coverage Insurance$237$169
Base MSRP$50,820$35,020
Average Annual Mileage10,27611,617

With an MSRP that's a quarter more than the going rate for a new vehicle, the Cadillac STS is on the more expensive side when it comes to price. At $50,820, the STS price comes in above the national average MSRP of $35,020. A used STS will be even less expensive, since there hasn't been a new model added to the market in the last few years.

Likewise, car insurance prices run above average when compared to other vehicles on the market. Liability insurance for a Cadillac STS is about $80 per month more than average, while full coverage is over $50 more a month.

However, it is worth noting that the STS drivers tend to use their cars less than the average American driver, with only 10,276 annual miles for the average owner.

The cost of insurance for the Cadillac STS is about the same as insuring the average car. Liability insurance runs an average of $83 per month, while full coverage will cost you around $177.

How can I get the best price on car insurance for my Cadillac STS?

The only way to make sure you're getting the cheapest price on car insurance is to check prices regularly and compare quotes from an array of carriers. Over time, your driver profile changes, so it's a good rule of thumb to review quotes every 6 months or so.

Does the color of my Cadillac STS affect my insurance premiums?

You may have heard the old adage that red cars cost more to insure than cars of other colors, but that's simply not true. There are a whole bunch of factors auto insurance carriers think about when they calculate how much you'll pay, but your car's color is not used to make that determination.

Do I need to have insurance before I buy a Cadillac STS?

You'll need to have valid insurance for your STS before you can legally drive your it off the dealership lot. Some dealerships might offer you an insurance policy as part of the car-buying process, but the best thing to do when buying a a new car is to talk with your auto insurance carrier beforehand.

What car insurance discounts can I get for my Cadillac STS?

There are a ton of discounts out there when it comes to car insurance. Many of them (like "pay-in-full discounts" and "safe driver discounts") are more based on you than the vehicle you drive, but if your STS has safety features like anti-lock brakes, airbags, anti-theft systems, and other features, it may qualify for certain discounts. To learn more about which discounts you may qualify for, contact your insurance company and ask about their discounts, since they differ quite a bit from company to company.
