How Car Insurance Premiums are Calculated in Montana

Car insurance companies in Montana consider several factors when calculating the price of your policy. The most important factors include adding a teen driver to your insurance, the coverage level you select and your age. For example, the coverage level you choose can multiply your insurance rates by 2.2x in Montana.

How Much Adding a Teen Driver Matters in Calculating Car Insurance in Montana

Car insurance companies consider teen drivers as high-risk due to inexperience. Research shows that teen drivers are nearly three times as likely as drivers aged 20 or older to be in a fatal crash. Therefore, insurers include this risk factor when calculating car insurance costs and charge more when you add a teen driver to your policy.

Adding a teen driver to your policy is the most expensive factor that affects your auto insurance rates in Montana, multiplying your premium by as much as 3.1x.

How Much Coverage Levels Matters in Calculating Car Insurance in Montana

The cost of your premium is also based on the level of coverage you choose. The cheapest option is the state minimum liability-only and the most expensive is full coverage with a 100/300/100 liability and $500 deductible. Choosing full coverage can increase your rates by 2.2x.

How Much Age of Driver Matters in Calculating Car Insurance in Montana

Your age is another factor insurers consider when calculating your auto insurance premiums. Compared to older drivers, younger drivers are riskier to insure because they’re inexperienced and more likely to get into an accident. Thus, insurance companies charge young drivers more for car insurance. If you’re 19 or 20 years old, your rates will be more expensive than those for a 40-year-old driver.

The cheapest car insurance in Montana is for a 40-year-old driver, while the priciest is for a 19 to 20-year old. Your age can affect your car insurance rates by 2.3x.

How Much Credit Score Matters in Calculating Car Insurance in Montana

Your credit score also plays a vital role in determining your car insurance rates in Montana. Drivers with poor credit are considered more likely to file a claim because they may not be able to pay for repairs out of pocket. Therefore, their car insurance costs tend to be higher than those for drivers with good credit.

In fact, having a poor credit score in Montana can multiply your premium by as much as 2.2x.

How Much Model of Car Matters in Calculating Car Insurance in Montana

In Montana, auto insurance providers also consider the type of car you drive when calculating your car insurance premiums. Luxury cars cost more to insure since they are more expensive to repair. Additionally, some vehicle models are more prone to theft and therefore require more protection.

A luxury sports car is the most expensive car to insure, while SUVs and sedans are typically cheaper. Drivers with vehicles that are expensive to insure may pay 2x more for their premiums.

How to Calculate How Much Car Insurance You Need in Montana

One of the most significant factors that affect the cost of your car insurance in Montana is how much insurance you buy. Calculating how much car insurance you need in Montana can help you choose a policy that balances affordability with the level of protection you prefer or need.

Montana requires specific coverage for bodily injury liability per person, bodily injury liability per accident and property damage liability per accident. However, you may wish to consider purchasing additional liability insurance and comprehensive and collision insurance, depending on your unique situation.


Understand Montana car insurance requirements

You can look up the minimum car insurance requirements in Montana to determine how much car insurance you need. It’s important to remember that state minimum insurance only covers 20/50/20: $25,000 bodily injury liability per person, $50,000 bodily injury liability per accident and $20,000 property damage liability per accident.

Montana doesn’t require drivers to buy comprehensive and collision insurance, which is the coverage that protects against damages to your vehicle.


Consider Purchasing Additional Liability Insurance

While car insurance that meets the state minimum offers basic protection, you might need liability insurance on top of it to protect yourself against the costs of a major accident. On average, minimum liability insurance in Montana costs $462. If you increase your bodily injury liability coverage to $300,000, you’ll pay $692 more.


Decide whether or not to buy comprehensive and collision insurance

Although Montana law doesn’t require comprehensive and collision insurance, it might be best to consider purchasing full coverage since it protects you from loss or damage to your vehicle. Montana doesn’t require full coverage, but lenders usually do.

It costs an average of $483 per year to add comprehensive and collision coverage with a $1,000 deductible. If the replacement value of your car is low, the added cost of this coverage may not make financial sense.


Consider buying additional protection besides these core coverages

Montana does not require uninsured/underinsured motorist coverage. However, 8.5% of motorists there are uninsured, so coverage may be an affordable way to protect against these drivers who are either uninsured or underinsured.

Montana also doesn’t require personal injury protection. As an alternative, you may wish to consider medical payments coverage as an add-on to your car insurance policy. Also known as MedPay, it can pay for your medical bills and cover the costs of injuries to your passengers.
