What affects your car insurance rate in Montana?

  • Your car’s make, model, year and trim
  • Your location within Montana
  • Your coverage level
  • Your driving history, credit score and vehicle storage

Does your vehicle model affect car insurance rates in Montana?

Your car’s make and model can play a major role in determining insurance rates. The make is the brand, and the model is the specific vehicle. For instance, Honda is the make and Accord is the model.

Insurers base pricing on repair and replacement costs, how often the model is involved in claims, and theft frequency. Two vehicles with similar prices can still have very different premiums.

For example, full coverage for a Honda Accord LX costs $2,466 per year in Montana, while the average premium for a Honda CR-V is $2,054 – a difference of $412.

Popular cars aren’t always cheaper to insure

High theft rates or costly repairs can raise premiums on common models. Check insurance costs before buying a vehicle.

Does your car’s model year affect insurance rates in Montana?

Newer cars generally cost more to insure because they are more expensive to repair or replace.

In Montana, insuring a 2024 Honda Accord LX costs $2,409, while the 2025 version costs $2,395.

However, older vehicles aren’t always cheaper – lack of safety features or costly parts can keep premiums high.

Check your state’s minimum coverage requirements

Every state sets its own minimum car insurance requirements, and Montana is no exception. To drive legally, you’ll need at least the minimum liability coverage, which typically includes:

According to III (Insurance Information Institute), state-required minimums are usually not able to cover the costs of a serious crash, so it’s important to consider higher levels of coverage for financial protection (III, n.d.). Not carrying the required coverage in Montana can lead to fines, license suspension and even vehicle impoundment.

Auto insurance premiums vary significantly from city to city, so drivers need to be sure they’re getting the best deal. Insure.com has done the research for you. Get more information on auto insurance rates by city below.

How does your car’s trim affect insurance rates in Montana?

Your car’s trim can affect how much you pay for insurance. Trim refers to a particular version of a model that includes different features, equipment, or engine options, such as LX, EX, or Sport.

For example, in Montana, full coverage for a 2024 Honda Accord LX costs $2,409 annually, while the Accord EX-L trim costs $2,427 – a difference of $18.

Features like premium audio systems or advanced tech can increase rates by raising the car’s value. Performance trims may also increase premiums due to higher risk.

Upgrading your trim can increase insurance costs

Higher trims often mean higher premiums because upgraded electronics, interiors, and components cost more to repair or replace. Before choosing a trim, it’s worth getting a quote on each option to see how the price difference carries over to your insurance.

How much does car insurance cost in Montana?

Frequently asked questions

What is the average cost of car insurance in Montana?

The average cost of full coverage car insurance in Montana is $2,476 per year, or $206 per month. Your actual rate will depend on your vehicle, coverage level, driving history and location within the state.

How can I lower my car insurance premium in Montana?

The most effective ways to lower your premium are comparing quotes from multiple carriers, increasing your deductible, bundling your auto policy with home or renters insurance, maintaining a clean driving record, and choosing a vehicle that costs less to insure. Discounts for safe driving, good grades or low annual mileage can also add up.

Does my credit score affect car insurance rates in Montana?
