Factors that affect car insurance rates

Car insurance rates can vary significantly among drivers based on many factors that insurers use to estimate risk. Some common rating factors include:

• Driving history: Insurers consider whether you have a clean record or infractions such as speeding, driving under the influence, or causing an accident.

• Age: Driving experience and accident risks closely correlate with age, data shows.

• Gender: Statistically, women are less likely to cause accidents or engage in risky behaviors like aggressive driving.

• Location: Where a policyholder lives and drives affects their exposure to risk factors such as extreme weather, vehicle crime rates, and accident rates.

• Credit history: Data indicates drivers with better credit are less likely to file car insurance claims than those with poor credit.

• Vehicle make and model: Less expensive vehicles or those with multiple safety features cost less to insure.

• Vehicle usage: Driving fewer miles per year reduces a vehicle’s exposure to the day-to-day risks of driving.

• Vehicle equipment: Safety features like lane-keeping assist and blind-spot warning can help decrease the risk of accidents.

• Coverage type: Generally, liability-only coverage costs less than full-coverage car insurance.

• Coverage limits: The amount of coverage you buy affects annual premiums; minimum coverage is typically the cheapest but doesn’t offer enough financial protection for most drivers.

• Deductible: A higher collision and comprehensive coverage deductible (liability coverage has no deductible) reduces rates since the insurer assumes less risk for the cost of repairs.

How to save on car insurance

Every U.S. state except New Hampshire requires drivers to carry at least a minimum amount of liability coverage. Insurance professionals recommend buying more coverage for greater financial protection in at-fault accidents. And if a driver leases or finances a vehicle, the leasing company or lender will require them to buy full-coverage car insurance.

Drivers can take steps to reduce the cost of car insurance, including:

• Drive safely. Avoid speeding, hard braking, distracted driving, and other risky driving behaviors that could cause a claim.

• Look for discounts. Most insurers offer discounts, such as good student or multi-car discounts, that can help reduce premiums.

• Increase the deductible. A higher collision/comprehensive deductible typically leads to lower rates.

• Adjust coverages. Liability-only coverage is the cheapest insurance available, and minimum coverage is the most affordable liability option. But drivers should be careful and buy enough coverage to adequately protect them financially.

• Comparison shop. Drivers should compare rates from multiple companies every time their policy comes up for renewal.

Methodology

Insurify data scientists analyzed more than 97 million rates from car insurance applications 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.  All premium averages reflect the cost of car insurance for drivers between the ages of 20 and 70 with a clean driving record and average or better credit.

For most states, full-coverage premium prices represent two-year rolling medians in order to manage extreme market volatility seen over the past few years as insurance companies have sought substantial rate increase approvals and deprioritized writing new policies in the face of rapidly rising costs.

Liability-only premium prices — as well as full-coverage prices in Maine, Massachusetts, Michigan, Montana, North Dakota, Nebraska, New Hampshire, New Jersey, and Vermont — represent one-year rolling medians. 

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

• Collision coverage with a $1,000 deductible
