  • Our editorial team spent more than 350 hours developing the Insurify Quality (IQ) Score and scoring insurance companies. The IQ Score objectively analyzes and calculates a score for insurers using more than 15 crucial criteria. The team weighted criteria by importance to the consumer — factors such as customer reviews and affordability influence the score more than availability and third-party ratings.

    We rate each company on a 1 to 10 scale based on five categories: financial ratings, customer satisfaction, affordability, customer support and transparency, and availability. Insurify updates ratings once a year or as more recent information becomes available.

    • Third-party financial ratings: Insurify uses data from AM Best, S&P, Moody’s, and more to compare insurance companies’ credit and ability to pay out future claims.
    • Customer satisfaction: To calculate this score, Insurify analyzed more than 55,000 customer reviews across 155 car insurance companies. We also consider third-party ratings from J.D. Power, the National Association of Insurance Commissioners, and Trustpilot.
    • Affordability: Our data scientists analyzed more than 90 million real-time auto insurance rates from our partners across the U.S., as well as available discounts, to calculate an affordability score.
    • Customer support and transparency: This measures coverage options, ease of claims filing, and the insurer's transparency surrounding discounts, coverages, and claims process.
    • Availability and reach: Insurify scores availability and reach by identifying the number of states in which insurers offer coverage and company size by market share.

My Experience with State Farm

Beware, some companies are more interested in making money than meeting the customers' needs. My wife had a medical issue while driving, and they covered it. A year later, there was a fender bender involving two moving vehicles. To me, it was no fault, but they considered it a second incident. We also had hail damage to our roof. They said there wasn't enough damage, yet my next-door neighbors received a new one. Now, they're canceling me for too much.

Why we picked this company

The largest U.S. auto insurer by market share, State Farm offers some of the lowest car insurance quotes in Boulder, including for liability-only and full-coverage policies. Rideshare drivers can easily add transportation network company (TNC) coverage to their policies, as well.

State Farm may be able to pay out claims with ease, but the claims process itself may be less than favorable, as noted by State Farm’s higher-than-average National Association of Insurance Commissioners (NAIC) customer complaint index. And drivers with new cars may find the lack of gap coverage with State Farm disappointing.

Pros
  • Rideshare insurance available

  • A++ (Superior) financial strength rating from AM Best, the highest level possible

Cons
  • Gap insurance not available

  • High rate of customer complaints with the NAIC

It's too hard to get past all the checks and balances to verify you're a member. There are too many questions and memory items to get past their firewall. Lastly, everyone is working remotely, and you can hear the family activities in the background.

I was in an accident which was not my fault, and my insurance increased to $118 a month. I don't drive my car much, less than 50 miles a day. Additionally, I have home insurance with USAA and my payment increased by $100. As a veteran, I find this totally wrong.

Why we picked this company

USAA may be a great option for military drivers searching for cheap car insurance with unique perks. Only active-duty military members or veterans, their families, and their children can be auto insurance policyholders. This membership is quite restrictive compared to other companies, though membership has its perks, like exclusive discounts for travel, dining, and shopping.

A great customer satisfaction score from a J.D. Power survey highlights happy policyholders; but some USAA members may be unhappy that they can’t reach a live agent on the phone 24/7.

Pros
  • High J.D. Power customer satisfaction rating in the Southwest region

  • Extensive member benefits beyond auto insurance

Cons
  • Limits membership to members of the military community

  • No 24/7 live customer service

How to get the cheapest car insurance in Boulder

It’s important to find the right auto insurance coverage for your needs, even if it’s not the cheapest auto insurance coverage. Rates change often, as do other savings incentives. To get the cheapest car insurance in Boulder, consider these tips:

  • Ask about loyalty perks. Your insurer may offer special discounts for longtime policyholders or give you a discount when bundling multiple policies, such as auto insurance and other personal insurance like homeowners insurance or renters insurance.

  • Ask about group insurance. If you belong to certain professional organizations, like an alumni group, or have certain employee benefits, you may be eligible for a cheaper group insurance policy.

  • Shop around. Since rates and incentives change regularly, it pays to shop around. You can use online comparison sites to see multiple car insurance quotes in minutes.

  • Reconsider coverage. If you drive an older, lower-value vehicle, it may not be worth insuring it with a full-coverage policy. Consider dropping optional coverages or reducing policy limits to save money.

Cheapest liability-only car insurance in Boulder: State Farm

All Boulder residents need to meet the minimum auto insurance requirements, which is what liability-only coverage provides.

Liability-only coverage in Boulder costs an average of $88 per month.

Cheapest full-coverage car insurance in Boulder: State Farm

Insurers don’t have a set definition for full-coverage car insurance, but this type of policy usually includes comprehensive coverage and collision coverage, along with liability injury coverage and property liability coverage.

A full-coverage policy is typically more expensive than a liability-only policy, as it adds more financial protection to your coverage. While liability insurance covers injuries and damages you cause to others and their property, full coverage pays for your own damages and injuries — depending on the included coverages.

Full-coverage policies in Boulder cost $191 per month, on average.

Car insurance requirements in Colorado

Increased public transportation between Boulder and Denver via the EcoPass, Neighborhood Pass, and CollegePass programs isn’t the only thing that’s changed for commuters since 2003. In the same year, Colorado changed from a no-fault state to an at-fault state. This means that drivers at fault in an accident are responsible for paying for the damages and injuries they cause to other parties. Drivers can usually pay for these losses through their liability insurance.

The current minimum insurance coverage state law requires includes bodily and property liability coverage.[1]

Coverage
Minimum Requirements
Bodily injury liability$25,000 per person per accident / $50,000 for all persons per accident
Property damage liability$15,000 per accident

While meeting Colorado’s minimum insurance requirements is enough to drive legally, it may not be enough coverage for everyone. Additional protection is available if you want more coverage than the minimum requirements provide. Colorado drivers could consider adding more auto insurance coverage, such as:

  • illustration card https://a.storyblok.com/f/162273/x/665da91bf7/comprehensive-coverage.svg

    Comprehensive coverage

    Comprehensive insurance provides protection against non-collision events like vandalism, theft, fire, and natural disasters.

  • illustration card https://a.storyblok.com/f/162273/x/169fdfde11/liability-coverage.svg

    Collision coverage

    Collision insurance protects you if you hit a stationary object or another vehicle, even if you’re at fault. It also covers rollover accidents and damage from hitting a pothole.

  • illustration card https://a.storyblok.com/f/162273/x/4c9753bdbe/medical-payments.svg

    Medical payments coverage

    Medical payments insurance covers medical expenses and funeral costs for you and your passengers. Colorado requires insurers to offer a minimum of $5,000 in MedPay coverage, but you can decline it in writing if you don't want the coverage.

  • illustration card https://a.storyblok.com/f/162273/x/5285c4cd74/uninsured-or-underinsured-motorist-coverage.svg

    Uninsured/underinsured motorist coverage

    Uninsured/underinsured motorist coverage pays for your injuries if the driver that hit you doesn’t have sufficient insurance coverage. Colorado requires insurers to offer this coverage to all policyholders. But if you don't want it, you can decline it in writing.

  • illustration card https://a.storyblok.com/f/162273/150x150/d7333ddf2e/car-and-driving-96x96-orange_046-car-accident.svg

    Accident forgiveness

    Purchasing optional accident forgiveness before an accident occurs can help ensure your car insurance premium doesn't rise after your first at-fault accident. Keep in mind, though, that you'll generally need to have a clean driving record for at least three years to qualify for this coverage.

  • illustration card https://a.storyblok.com/f/162273/150x150/e80d4ae197/car-and-driving-96x96-gold_019-car.svg

    Gap insurance

    If you've leased or financed your vehicle, gap insurance can offer greater financial protection in case your car is totaled. Gap coverage can pay the difference between your remaining loan or lease balance and your car insurance payout. Without gap insurance, you could be on the hook for paying of your car loan or lease if your car is totaled.

Cheapest car insurance for drivers with an incident

Your car insurance premiums with a clean driving record will likely be much lower than if you have an incident on your driving record. Incidents can include things like speeding tickets and other traffic violations, driving under the influence, and being in an at-fault accident.

These incidents can affect your rate in different ways, but all are traffic violations that ultimately may lead to your insurer paying out a claim.

Cheapest car insurance for drivers with a speeding ticket: State Farm

No matter the roadway — but especially in construction zones and during inclement weather — speeding increases your chances of getting into a car accident. Speed is a contributing factor in car crashes, so it makes sense that an insurer might raise your rates for several years when you get a speeding ticket, even if you weren’t involved in an accident.[2]

Boulder drivers with a speeding ticket pay an average of $127 per month for liability coverage and $276 per month for full coverage.

If you need cheaper rates after getting a speeding ticket, check out the table below for the cheapest liability rates in Boulder for drivers with this incident.

Cheapest car insurance for drivers with an at-fault accident: State Farm

Boulder had more than 1,400 traffic accidents in 2023, resulting in three fatalities and 470 injuries, according to Colorado Department of Transportation data. An at-fault accident — even when there are no injuries or significant property damage — is an incident that may raise your rates. Filing an at-fault claim forces your insurer to pay money for your claim; it’ll likely raise your rates to compensate for its financial loss.

Liability insurance costs $123 per month, on average, for drivers in Boulder with an accident.

Cheapest car insurance for drivers with a DUI: State Farm

Colorado has a high conviction rate for DUI charges, and officers can arrest a driver with any BAC if they seem impaired.[3] A DUI is a serious offense. In Colorado, DUIs stay on your motor vehicle record for 10 years, so people in Boulder who drive under the influence should anticipate high rate increases after a conviction. Some insurers may even drop them from the policy.

Boulder drivers with a DUI pay a monthly average of $141 for liability coverage. The cost for a full-coverage policy jumps to $306 per month.

This is because older adults have an increased risk of accidents.[5]

Senior drivers in Boulder pay $65 per month for a minimum-coverage policy, on average. Check out affordable rates for senior drivers in the table below.

Cheapest car insurance for teens: State Farm

In the Boulder area, distracted driving was a factor in 17% of fatal crashes for drivers between 15 and 20 years old.[4] Boulder teens should expect higher rates than drivers of other age groups, including young drivers between 20 and 25 years old. Across the nation, teens have a higher risk of fatal car accidents due to inexperience, overconfidence, increased distractions, and risky driving behaviors.

Liability-only insurance for teens in Boulder costs $159 per month, and full coverage costs $346 per month, on average.

Great ways for teen drivers to get the cheapest rates for their car insurance in Boulder County include driving a car with the latest safety features, completing driving safety courses, staying on their parents’ insurance policies, and qualifying for good student discounts. Minor teens can't legally buy their own car insurance policy without the written consent of a parent or guardian.

Is car insurance more expensive in Boulder?

The overall average cost of car insurance in Boulder is $139, which is less than the statewide average of $158 and the national average of $153.

Methodology

Insurify data scientists analyzed more than 90 million quotes served to car insurance applicants in Insurify’s proprietary database to calculate the premium averages displayed on this page. These premiums are real quotes that come directly from Insurify’s 50+ partner insurance companies in all 50 states and Washington, D.C. Quote averages represent the median price for a quote across the given coverage level, driver subset, and geographic area.

Unless otherwise specified, quoted rates reflect the average cost for drivers between 20 and 70 years old with a clean driving record and average or better credit (a credit score of 600 or higher).

Liability-only premium averages correspond to policies with the following coverage limits:

  • Bodily injury limits between state-minimum rates and $50,000 per person, $100,000 per accident
  • Property damage limits between $10,000 and $50,000
  • No additional coverage
Full-coverage premium averages correspond to the same bodily injury and property damage limits in addition to:
  • Comprehensive coverage with a $1,000 deductible
