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.

Missoula$2,175
Helena$2,224
Anaconda-Deer Lodge County$2,310
Belgrade$2,320
Bozeman$2,331

Average car insurance cost in Montana by age

Insurers consider age a key risk factor when determining car insurance rates. Our data shows that young drivers typically pay higher premiums due to their limited experience behind the wheel.

Generally, rates are highest for teens, begin to drop after age 25 and rise again once drivers reach their early 70s.

Let’s take a closer look at how much you might pay in Montana for a full coverage policy based on your age and gender.

Average car insurance cost in Montana for young drivers

If you’re a young driver, you can expect to pay above average premiums. Insurers see young drivers as high-risk, which means higher premiums until you gain more experience behind the wheel.

For instance, 20-year-old male drivers in Montana pay an average of $5,535 per year for car insurance, while females of the same age pay $5,236.

But by the time you turn 25, insurance premiums drop to $3,003 a year on average for male drivers and $2,946 for female drivers.
