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?

A vehicle’s make and model can significantly impact car insurance rates. ‘Make’ refers to the brand and ‘model’ refers to the specific model you drive. For example, Honda (make) Accord (model).

Insurers price based on how much a vehicle costs to repair or replace, how often that model is involved in claims, and how frequently it’s stolen. Two vehicles at the same price point can carry meaningfully 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 expensive repair costs can push premiums up on common models. Check insurance costs before you buy, not after.

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

Each state sets minimum insurance requirements, including Montana. To drive legally, you’ll need liability coverage that 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. Not carrying the required coverage 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?

Insurance rates often vary based on your car’s trim. Trim is a version of a vehicle model with 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.

Premium features like advanced infotainment or high-end audio systems can increase rates by raising the vehicle’s value. Performance trims may also cost more due to higher accident risk.

That upgrade can cost more than you expect

Moving to a higher trim can increase your insurance premium due to higher repair and replacement costs – not just the purchase price. Before choosing a trim, it’s worth getting a quote on each option to see how the price difference carries over to your insurance.
