How Much Does Car Insurance Cost?

Car insurance averages are easy to quote and surprisingly easy to misunderstand. Two reputable sources can publish very different national numbers without either one being wrong because they may be measuring different drivers, coverage packages, states, or pricing dates.

Useful cost analysis begins by identifying what the number represents. Historical market spending, a standardized rate study, a state sample premium, and your own insurer quote answer different questions.

Finding one national figure does not establish whether your policy is cheap or expensive. It is to understand the benchmark, identify the major reasons your premium differs, and compare prices on the same coverage basis.

How Much Does Car Insurance Cost on Average?

Nationwide public benchmarking starts with the National Association of Insurance Commissioners’ Auto Insurance Database. Adopted in December 2025, the latest full report contains personal auto premium data through 2023.

Among the three measures, combined average premium comes closest to a broad liability-plus-physical-damage benchmark, but it still should not be labeled a universal “full coverage” price. Policies in the underlying data use different liability limits, deductibles, vehicles, driver profiles, and state-specific benefits.

Average expenditure answers a different question. Because every insured vehicle is assumed to carry liability while some do not carry collision or comprehensive, the expenditure measure reflects what consumers actually spent across a mixed market rather than the price of one fixed package.

What the Official National Averages Actually Measure

Insurance data become useful only after the denominator is clear. Exposure is expressed in car-years, with one car-year representing one vehicle insured for one year.

Combined average premium in the report adds the average premium for three broad coverage categories:

• Coverage categorized as liability-related
• Collision coverage
• Comprehensive coverage

Liability data are broader than a simple bodily injury and property damage quote. Depending on the state and reporting structure, the liability category can include items such as uninsured or underinsured motorist coverage, medical payments, PIP, and other liability-related components.

Likewise, the collision and comprehensive figures are averages across insured vehicles that carry those coverages. Deductible choices as different as $250 and $1,000—and vehicles as different as a new luxury SUV and a ten-year-old sedan—do not represent the same underlying risk even though their premiums ultimately flow into aggregate state data.

Drivers deciding what protection belongs in their own policy should first determine how much car insurance they need. Price comparisons make more sense after the coverage decision, not before it.

Why Published Car Insurance Averages Can Disagree

Online cost estimates often differ because the methodologies are solving different problems.

Rate studies may quote a 35-year-old driver with a clean record, specific liability limits, collision and comprehensive, and a fixed deductible. Another analysis may use a different age, credit tier where permitted, vehicle, or coverage definition. Both can produce legitimate averages that should not be treated as interchangeable.

State-minimum coverage also lacks one national specification because state requirements differ. Averages built from minimum-policy profiles can therefore contain materially different benefits from one jurisdiction to another.

Even the phrase “full coverage” is informal. It commonly refers to liability, collision, and comprehensive, but no single national set of limits, deductibles, or optional benefits defines the term.

Why Your Car Insurance Premium Can Differ So Much

Insurers price expected risk and claims cost under rating plans allowed in the state. Insurer and jurisdiction differences in factor weighting help explain why two companies can quote the same household very differently.

Common pricing inputs can include:

• Driving record and claims history
• Years of driving experience
• Age or other driver characteristics where state law permits
• Where the vehicle is garaged
• Annual mileage and vehicle use
• Vehicle make, model, age, value, repair characteristics, and theft experience
• Drivers and vehicles on the policy
• Liability limits and other selected coverage
• Collision and comprehensive deductibles
• Prior insurance history where permitted
• Credit-based insurance information where permitted
• Telematics or usage-based information when the consumer participates in an applicable program
• Discounts and insurer-specific rating rules

State law can restrict or prohibit some rating factors, so a factor commonly used in one jurisdiction may be unavailable in another. Company underwriting also matters: insurers do not assign identical prices to identical characteristics.

Premiums far above the national average are not automatically evidence of overcharging. Higher-risk locations, more expensive vehicles, inexperienced drivers, broader limits, lower deductibles, or recent claims and violations can all push the price upward.

Very low premiums deserve equal caution because they can reflect less coverage, higher deductibles, omitted drivers, or discounts with conditions rather than a strictly better price.

Coverage Choices Can Change the Price Substantially

Premium is partly a financing decision about which losses you transfer to the insurer and which losses you retain yourself.

Liability Limits

Increasing bodily injury and property damage limits generally transfers more potential liability to the insurer, subject to the policy. Pricing several limit tiers shows whether materially more liability protection costs a modest or substantial amount for your particular profile.

Legal minimums establish a floor, not a financial recommendation. Serious at-fault crashes can exceed low limits even when the policy fully satisfies state law.

Physical-Damage Coverage

Adding physical-damage protection raises premium because the policy can respond to covered damage to your own vehicle. Collision generally addresses crash-related damage, while comprehensive covers specified non-collision losses such as theft, hail, fire, or animal impact.

Vehicle value and financing status change the decision. Lenders and lessors commonly require both coverages while they have a financial interest in the car, whereas an owner of a paid-off low-value vehicle may decide to retain more of that risk.

Deductibles

Higher deductibles usually lower the physical-damage premium because you absorb more of a covered loss. Cheapest-on-paper deductible choices are not automatically the best financial choices.

Deductible trade-offs are covered in choosing a car insurance deductible.

Optional Benefits

UM/UIM, PIP, MedPay, rental reimbursement, roadside assistance, GAP, and other protections can also affect premium when they are optional or available above required amounts. Each one solves a different risk, so stripping add-ons solely to hit an average price can create coverage gaps that cost much more after a loss.

Location and State Rules Matter

Geography affects auto insurance through more than one channel. State liability requirements, no-fault rules, rate regulation, claim patterns, traffic density, repair costs, medical and legal costs, theft, weather, and population density can all contribute to differences in average premiums.

Wide geographic variation appears in the 2023 NAIC combined average premium even before individual driver differences are considered:

These numbers should not be used as a state ranking of equivalent policies. Direct interstate comparisons can mislead because coverage purchases, policyholder characteristics, state laws, traffic conditions, and other factors differ.

Location also operates below the state level. Claim frequency, theft, traffic, repair availability, and other loss characteristics can vary between communities, so moving within the same state can change a quote.

Why Car Insurance Prices Change Over Time

Market averages and current price movement are separate concepts. Historical NAIC data record what was written and spent across the market during a calendar year; the Bureau of Labor Statistics’ motor vehicle insurance component of the Consumer Price Index tracks price change over time for a more uniform insurance product.

Those measures can move differently because consumers also change what they buy. During periods of rising prices, some households may raise deductibles or drop optional physical-damage coverage, which can dampen average expenditure even while the price of a constant insurance product rises.

Countrywide combined average premium rose 14.42% in 2023 from the prior year in the 2022/2023 NAIC report. More recent BLS data tell a different short-term story: the motor vehicle insurance CPI was 4.5% lower in July 2026 than in July 2025 and declined 0.3% from June 2026 on a seasonally adjusted basis.

Claim costs still influence insurer pricing over time. Repair costs, parts and labor, medical and legal costs, theft, weather, accident rates, and other loss conditions can all affect state premiums.

How to Compare Your Premium With an Average

Benchmarks work best as prompts for investigation rather than verdicts.

Start with the annualized cost of your current policy or quote. Six-month premiums can be doubled for a rough annual comparison, but installment fees or other charges may make actual annual cash outflow differ.

Then compare the policy structure:

1. Liability limits: Are you comparing the same bodily injury and property damage limits?
2. Collision and comprehensive: Are both included or excluded on the same vehicles?
3. Deductibles: Do the physical-damage deductibles match?
4. UM/UIM: Are the same limits and coverage forms included?
5. PIP or MedPay: Are required and optional medical benefits comparable?
6. Household drivers: Are all regular drivers represented consistently?
7. Vehicles and use: Are mileage, garaging, commuting, and vehicle details accurate?
8. Discounts: Do the quotes assume the same bundling, telematics, payment, or other conditions?

Only after those items align does the premium difference become a useful price comparison. Quote comparisons should match coverages and limits rather than rely on headline prices alone.

Drivers wanting a quick reference can compare an entered premium with the official 2023 state data using the car insurance calculator. Treat the result as historical context, not a personalized underwriting estimate.

Build the Insurance Cost Into the Car Budget

Insurance should be priced before the vehicle purchase, not discovered after financing is complete. Two cars with similar purchase prices can create very different insurance costs because repair complexity, theft experience, safety characteristics, parts prices, and insurer loss history differ.

Existing-vehicle budgets should convert the premium into the same time frame used for the rest of the household budget. Annual policies can be divided by 12 for a monthly planning amount; six-month policies can be divided by six. Installment charges belong in the budget separately when the insurer adds them.

Also budget for the deductible. Consider a $2,000 annual premium and a $1,000 collision deductible: the premium is predictable, while the deductible becomes relevant only when a covered claim occurs.

Do not treat the deductible reserve as an annual expense unless a claim occurs. Its purpose is liquidity: the policy works better when the household can actually fund the retained portion of a loss.

Summary

Official national auto-insurance benchmarking remains historical rather than real-time. For 2023, the database reports an average expenditure of $1,281.92 per insured vehicle, a liability average premium of $736.65, and a combined liability-plus-collision-plus-comprehensive average premium of $1,438.60.

None of those figures tells an individual driver what a 2026 policy should cost. Location, state law, vehicle, driver history, coverage limits, deductibles, household composition, insurer rating, and other permitted factors can move the actual quote far from the average.

Use market averages to understand context. Purchase decisions should start with the protection you need, followed by several quotes on identical terms rather than shopping to an arbitrary national number.
