If you live in Montana, you can expect to pay an average of around $212 per month for full coverage car insurance, or $2,541 per year. If you carry only your state’s minimum required liability coverage, your cost drops to about $35 monthly or $422 annually.

Location plays a big role in what you pay for car insurance. Insurers calculate rates based on state-specific risk factors such as accident frequency, repair and medical costs, theft rates, and even weather-related risks. Urban areas with heavy traffic or higher crime rates tend to see higher premiums, while rural areas are often cheaper. Beyond location, your age, driving record, credit score, ZIP code, and the type of car you drive also affect your rate.

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

Car insurance rates can vary widely depending on where you live, even within Montana.

On the other hand, car insurance is generally more affordable in cities like Missoula or Helena, with average annual premiums between $2,175 and $2,224.

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.
