A full coverage car insurance policy costs around $2,541 a year or $212 per month for Montana drivers. However, if you choose to get the state’s minimum liability coverage, you’ll pay $422 a year.

Where you live plays a big role in what you pay for car insurance. Insurers factor in local accident rates, repair and medical costs, theft trends, and even weather risks when setting premiums. If you’re in a crowded city with high traffic or crime rates, you’ll typically pay more, whereas quieter rural areas usually come with lower premiums. But location isn’t everything – your age, driving history, credit score, ZIP code and even the type of car you drive also play a role in determining your final premium.

Average cost of car insurance by coverage levels in Montana

Your car insurance premium is determined by the coverage limits you choose.

If you purchase only the state’s minimum liability limits, you’ll pay $35 per month or $422 annually. While an affordable option, it only includes liability coverage. That means any damage to your own vehicle won’t be covered.

If you’re looking for more robust protection, consider choosing full coverage car insurance. It includes liability coverage, plus collision and comprehensive insurance. Collision coverage covers damage to your vehicle in an accident, no matter who’s at fault. Comprehensive insurance covers theft, vandalism or weather-related damage to your car.

In Montana, drivers typically pay $212 per month or $2,541 annually for full coverage car insurance.

Although it costs more than minimum coverage, full coverage can be a smart choice -particularly if you have a newer or financed vehicle.

Coverage limitsAverage annual cost
State minimum liability-only$422
Liability only$604
Full coverage$2,541
Non-owner state minimum liability$326

Average car insurance cost in Montana by city

Because car insurance rates vary by location, the city you live in also affects how much you pay. If you’re in cities like Havre, Kalispell or Billings, you’ll likely see higher premiums because of high traffic and accident rates, and greater risk of theft or damage.

On the other hand, drivers in cities like Missoula or Helena pay significantly low insurance rates, on average between $2,175 and $2,224 a year. Insurers typically charge lower premiums in these cities due to fewer accidents, lower population density, vehicle theft and vandalism rates.

Belgrade$2,320

Average car insurance cost in Montana by age

Age plays a significant role in how insurers calculate car insurance costs. Young drivers usually pay more, as their inexperience on the road makes them a higher risk.

Rates are often highest for teenagers, begin to decrease after 25, and then climb again once drivers are in their 70s.

Let’s break down what you can expect to pay in Montana for full coverage, depending on your age and gender.

Average car insurance cost in Montana for young drivers

As a young driver, you’ll likely face higher-than-average insurance rates. Because of limited driving experience, insurers view young drivers as riskier, resulting in higher insurance rates until they gain more experience on the road.

In Montana, 20-year-old male drivers pay an average of $5,535 per year for car insurance, while their female counterparts pay $5,236 for the same coverage.

However, by age 25, average car insurance costs drop to about $3,003 per year for male drivers and $2,946 for female drivers.
