Why is my car insurance so high: the rating factors to check, in order

A high quote is a rating result, not a single charge. Place your quote against the NAIC published benchmark, then work through the factors insurers actually use and separate what you can change from what you cannot.

Estimates and published averages, not a quote. Not insurance advice. State rules and insurer rules vary. Confirm requirements with your state insurance regulator or a licensed agent in your state.

Start with the reading: how far are you from the benchmark

Before diagnosing a high premium, place the quote against a published benchmark for the same coverage. In the NAIC 2024 data behind this site, the countrywide combined average premium was $1,613 per insured vehicle for liability plus collision plus comprehensive, and the countrywide liability average premium was $813. State readings differ widely: Florida recorded a combined average premium of $2,175 in 2024, which is $562, or 34.8%, above the countrywide figure. A worked example shows how to use the reading. Take a hypothetical quote of $1,800 a year and compare it with the countrywide combined figure of $1,613: the gap is $187, or 11.6%. That gap is a starting point for questions, not a verdict, because the right comparator is your own state benchmark on your state index page, matched for coverage type. If your quote sits near your state benchmark, the price may be the market rather than a mistake. If it sits far above the benchmark, the factors below explain where the distance usually comes from, and which of them you can act on.

How the price is built: underwriting first, rating second

The NAIC consumer auto guidance describes two steps. In underwriting, the insurer assesses the risk of an applicant, groups the applicant with similar risks, and decides whether to accept the application. In rating, the insurer assigns a price based on what it expects it will cost to take on that financial responsibility. The NAIC states that the single greatest influence on rating is claim frequency, meaning how often insured events occur within a group relative to the number of policies in that group, not only how often you personally have claimed. A driver who shares characteristics with a high claims group can be charged more even with a clean personal record. Each insurer adopts its own rating system within state rules, so the same driver, car and coverage can produce different prices at different insurers. That is why this guide ends with a worksheet rather than a single explanation: a high premium is normally several factors stacked together, and the useful question is which factors are doing the stacking in your case.

The cost layer under every factor: fewer claims, larger claims

Every factor below is a way of sorting drivers into groups, and every group is priced from the same underlying thing: what its claims cost. That cost has a public industry reading. ISO, the Verisk Analytics statistical agent, compiles private passenger auto losses, and the Insurance Information Institute republishes the series on its Facts + Statistics: Auto insurance page, checked October 29, 2026. It reports two numbers for each coverage. Claim frequency is claims per 100 earned car years, a car year being 365 days of insured coverage for one vehicle. Claim severity is the size of the loss.

Between 2015 and 2024 the two numbers moved in opposite directions on three of the four coverages. Bodily injury liability frequency fell from 0.89 to 0.80 claims per 100 car-years, down 10.1 percent, while the average claim rose from $17,014 to $28,278, up 66.2 percent. Property damage liability frequency fell from 3.45 to 2.50, down 27.5 percent, while the average claim rose from $3,628 to $6,770, up 86.6 percent. Collision frequency fell from 6.01 to 4.16, down 30.8 percent, while the average claim rose from $3,377 to $5,489, up 62.5 percent. Comprehensive was the exception: frequency rose from 2.62 to 3.95 and the average claim from $1,679 to $2,306, up 50.8 and 37.3 percent.

That pattern answers the question many drivers bring to this page: why does insurance cost more when I, and drivers in general, are crashing less often? In this series, crashes producing paid claims did become less frequent per insured car on three coverages. Each paid claim became far more expensive. The direction of the premium follows the product of the two, not either one alone.

Frequency times severity: the claim cost per insured car

Multiply the two readings and divide by 100 and you get a rough claim cost per insured car-year for each coverage. This is our arithmetic on the published figures, not an ISO statistic, and it leaves out the insurer’s expenses, taxes and profit, so it is not a premium. It is the part of a premium that pays claims, measured for the average car in the data. For bodily injury liability it rose from about $151 per car-year in 2015 to about $226 in 2024, up 49.4 percent. For property damage liability it rose from about $125 to about $169, up 35.2 percent. For collision, the falling frequency nearly offset the rising severity, and the product rose from about $203 to about $228, up 12.5 percent. For comprehensive, with both readings rising, it roughly doubled, from about $44 to about $91, up 107.1 percent.

Read the four lines against your own declarations page. Bodily injury liability shows the largest dollar rise, about $75 per car-year, and the liability lines are the ones no driver can drop. Collision is the line where fewer claims did the most to hold costs down. Comprehensive more than doubled from a small base, and its count includes glass while excluding wind and water losses, per the table footnotes, so the growth did not come from wind and water claims. If your renewal rose mostly on liability, the cost layer above can be a large part of the explanation even when no factor of yours changed.

Three limits keep this reading honest. The series covers paid claims for all limits combined, and its liability severity includes loss adjustment expenses. Each line excludes some states: bodily injury leaves out Massachusetts and most no-fault states, property damage leaves out Massachusetts, Michigan and New Jersey, and the physical damage lines leave out Massachusetts, Michigan and Puerto Rico and are based on coverage with a $500 deductible. And it is a national pool. Your state, your territory and your insurer’s own book can move differently, which is why the state benchmark on your state page, not this national series, is the comparison for your quote.

Do not subtract one reading from the other. The benchmark on this site is a premium measure: the NAIC combined average premium was $1,613 per insured vehicle countrywide in 2024 (NAIC 2024 supplement, Table 5), money policyholders paid for liability, collision and comprehensive together. The ISO figures above are claims measures, money paid out on claims, coverage by coverage, with different state exclusions on each line. The two do not cover the same states, the same year boundaries or the same coverage bundle, so the difference between them is not a profit or expense figure, and this guide does not compute one. Use the ISO series for direction, which way claim costs moved and by how much, and use the NAIC benchmark for level, whether your own premium sits in a normal range for your state. A quote that is high against the benchmark is a question about your factors and your insurer; a renewal that rose with the ISO direction is partly a question about the whole market.

What vehicle data add: why the type of car moves collision cost

Factor three below, the car itself, also has a public cost reading. The Highway Loss Data Institute publishes collision losses for recent models, and the Insurance Information Institute republishes the summary for 2022 to 2024 model years on the same Facts + Statistics page. For passenger cars, a group that includes minivans, collision claim frequency was 7.2 per 100 insured vehicle years, average claim severity $10,298 and the average loss payment per insured vehicle year $737. For pickups the readings were 5.1, $10,354 and $533. For SUVs, 5.5, $10,220 and $562. Across all passenger vehicles, 5.9, $10,267 and $604.

The useful fact is where the gap comes from. The average collision claim was almost the same across the three body types, within $134 of each other. The difference was frequency. Passenger cars produced about 1.41 times as many collision claims per insured vehicle year as pickups, and their loss per insured vehicle year was about 1.38 times as high. Collision cost by body type, in this summary, is mainly a question of how often the vehicles are in collision claims, not how expensive each repair is. That says nothing about a particular model, and HLDI’s model-level figures are not part of this summary. It does explain why two drivers with identical records can see different collision lines when one drives a sedan and the other a pickup.

These are recent model years, so their average claims, above $10,000, sit well above the all-vehicle ISO collision average of $5,489 in 2024, which covers cars of every age. A newer car costs more to repair when it is damaged, which is the same point the car factor below makes from the Insurance Information Institute’s list of inputs. Before you buy, ask for a quote on the replacement car; the factor stops being a surprise once it is a line on a quote. More on vehicle type and electric cars is in electric vehicle car insurance.

Why the bill can rise when your own record did not change

Put the cost layer beside the NAIC description of rating and the clean-record renewal increase stops being a mystery. The NAIC consumer guidance states that the single greatest influence on the rating process is claim frequency, measured as how often an insured event occurs within a group relative to the number of policies in that group. An insurer prices the group’s expected claim cost, and when the average claim in that group grows, as the liability and collision severity figures above did, the group’s price rises with it. Your own clean year keeps you in the better groups; it does not exempt you from the cost of the claims those groups produce. A driver newly arrived from abroad is the opposite case: the US motor vehicle record and claims file are empty rather than clean, and how that reads on an application is covered in car insurance with a foreign driver’s license.

Two practical moves follow. First, separate the two causes on your own renewal. Ask the insurer, in writing, whether the change came from a rate change approved for the whole book or from a change in your own rating factors. A book-wide rate change is filed with the state, and the filing can often be read, as shown in reading your insurer’s rate filing. A change in your factors is a list you can check against your declarations page. Second, compare like with like: a renewal increase from a rising cost base affects other insurers’ prices too, so quotes at an identical specification are the only way to see whether your insurer’s share of it is out of line. The line-by-line split of a renewal increase is in the renewal increase analyzer, and the national price index history is in the car insurance price trend.

Factor one: your record, and the records of everyone on the policy

Your driving record is the factor most drivers expect, and it is real. Tickets, at-fault crashes and claims move a driver into a higher risk tier, and the NAIC Consumer’s Guide to Auto Insurance (2022) notes that insurers review driving records over roughly the last three to five years and check previous claims through reporting databases such as CLUE. The records of other drivers on the policy count as well, because the insurer is pricing the household it is covering, not one person in isolation. A serious violation has its own long tail: our guides on DUI cost impact and on SR-22 filings explain how a conviction and a filing requirement keep a higher tier in place under state monitoring. A driver with no track record can also pay more: the Insurance Information Institute notes that you may also pay more if you are a new driver without an insurance track record. If your record is clean and long, this factor is probably not the explanation, and the worksheet should move you quickly to the next four factors.

Factor two: where the car is garaged, and how far it travels

Insurers rate the territory where the car is kept, based on claims experience in that area. The NAIC shopping guide states that your premium will be higher or lower based on the insurer’s claims experience in the ZIP code or territory where you live, and that urban areas tend to have higher rates than suburban or rural areas. The Insurance Information Institute adds the related mechanisms: higher rates of vandalism, theft and accidents in urban areas, and whether the car is parked on the street or in a secure garage. Use matters as well as place. Annual mileage, a long commute and business use all raise exposure, because more miles mean more chances for a claim. Driving for a rideshare app is a separate case, because a personal policy can exclude it altogether; see rideshare insurance explained. This factor is also where plain errors hide. If your declarations page shows the wrong garaging address, an old commute distance, or a car listed at a former home, the rating is being built on facts that are no longer true. Correcting the record is not a discount claim; it is making the insurer rate the situation you actually have. How a move changes the garaging address is covered in moving to another state.

Factor three: the car itself

The vehicle is rated on what a claim on it is likely to cost. The Insurance Information Institute lists the cost of the car, the likelihood of theft, the cost of repairs, its engine size and the overall safety record among the inputs, and notes that insurers also look at how much potential damage a vehicle can inflict on another car. A newer car can cost more to insure than the older car it replaced even for the same driver, because sensors, cameras and body systems have raised the cost of ordinary repairs, and because the insurer’s maximum property payment is tied to a higher vehicle value. Safety equipment can work in the other direction for some coverages, but no single feature decides the reading. When you compare your premium with a neighbor’s, compare the cars before you compare the drivers: a different model year, trim or repair cost profile can explain a gap that looks personal but is mechanical. If a vehicle change is coming anyway, asking for a quote on the replacement car before you buy it turns this factor from a surprise into a known input.

Factor four: the coverage you bought

Part of a high reading is often the coverage itself. Higher liability limits cost more than lower limits, a lower deductible costs more than a higher one, and collision and comprehensive add premium that a liability only policy does not carry. The NAIC shopping guide states these relationships directly: rates are higher for higher limits, and higher for lower deductibles. The scale is visible in the published averages. The countrywide combined average premium of $1,613 in 2024 sits $800 above the liability average premium of $813, because the combined measure includes collision and comprehensive for one insured vehicle on top of liability. Those are group averages, not a price for adding coverage to your policy, but they show why two quotes cannot be compared until the limits, deductibles and coverage types match line by line. A quote that looks high may be carrying higher limits you chose at an earlier renewal and forgot. Read the declarations page before you shop, and use our deductible guide if the deductible line is the part you are weighing.

Factor five: household, history and the conditions set by your state

Some factors describe your household rather than you personally. When several drivers share cars, the NAIC shopping guide explains that insurers have principal operator rules, and some assign the highest risk driver, usually the youngest in the household, as the principal operator of a car even if that driver uses it very little. Age and years of licensed experience are rating inputs where state law allows. Continuity matters too: a gap in coverage can price worse than an unbroken history, which is why letting a policy lapse to save a month of premium can raise the next reading. Where state law allows, many insurers use a credit based insurance score, a statistical score built from credit information; the NAIC consumer guide notes that some states restrict how it can be used and several ban it entirely. Behind the household sits the state environment the Insurance Information Institute lists: litigation cost and frequency, medical care and repair costs, insurance fraud prevalence and weather trends. None of those is yours to change, and they are part of why the same driver can be quoted very different figures after a move.

The worksheet: sort each factor into changeable now, changeable later, or not yours

Write your quote, your state benchmark and the gap at the top of a page, using the worked example in the first section as the pattern. Then sort what you found. Changeable now: errors on the declarations page, a garaging address or mileage figure that no longer matches your life, a driver or vehicle that should no longer be listed, and any discount you believe you qualify for, which you should ask the insurer to confirm or refuse in writing rather than assume. Changeable later: a violation that will age out of the three to five year review window, a deductible you could raise once you hold the cash to pay it, and the vehicle itself at replacement time. Not yours to change: the claim frequency of your rating group, the repair and medical cost environment of your state, and a past event that has not yet aged off. Finish by asking your insurer, in writing, which rating factors moved your premium at the last renewal. The answer turns a vague high price into a list you can work through at the next renewal, one factor at a time.
