Car Insurance Calculator: Get Instant Rate Estimates & Calculate Coverage Need

Our car insurance coverage calculator helps you determine how much car insurance you should buy to make sure you are appropriately protected. It guides you in choosing the right liability limits and deciding whether you need comprehensive and collision (full coverage). You can compare the cheapest full coverage and cheapest minimum liability coverage options to find protection that fits your budget.

Insurance companies use several factors to estimate your risk of filing a claim. These insurance rating factors include your age, driving history, vehicle type and credit score (depending on the state). Where you live, your annual mileage and even your gender (in some states) all influence your rate.

Insurance companies rely on actuarial science and complex algorithms to predict the likelihood of claims and set premiums accordingly. Since each company weighs these factors differently, rates can vary widely for the same coverage. Regional insurers have lower overhead costs, and companies offering specialized policies, such as pay-per-mile insurance, can pass those savings along. Insurers also offer different discount structures that can reduce your rate by 5% to 40%.

The same 40-year-old driver with good credit and no violations pays $97 monthly with Travelers but $215 with AIG. That's an $118 difference for identical coverage. Comparing car insurance quotes from several companies for the same coverage is your best strategy to save.

Age is the biggest rate factor after your insurer. Teenage drivers pay significantly more. A 16-year-old pays roughly $450 extra each month compared to a 60-year-old for the same coverage.

Car insurance rates follow a U-shaped curve and are highest for policyholders under 25, lowest for middle-aged drivers (30 to 60), then gradually increase for seniors over 70. While you can't change your age, you can find a car insurance company that charges a lower rate for your age.

Your state and neighborhood affect your rates. New York drivers pay almost $200 more monthly than those in Wyoming, largely due to higher accident rates, theft risk, and population density.

Urban areas see higher rates because of increased traffic, accidents, and crime. Weather matters too. States with frequent hail, hurricanes, or severe storms charge more for comprehensive coverage. Each state also sets different minimum coverage requirements, which directly impacts your bill.

Different cars cost different amounts to insure. A BMW 330i runs $700 or more monthly than a 2025 Subaru Forester due to repair costs, safety ratings, theft rates, and vehicle value.

Luxury vehicles and sports cars carry higher rates because of expensive parts and performance-related risk. Older vehicles cost less to insure than newer ones, since they're worth less to replace.  See our guide to the cheapest vehicles to insure.

Car insurance costs vary depending on the type of coverage you select. Maximum full coverage costs roughly $400 more per month than minimum liability-only coverage.

Minimum coverage protects others if you cause an accident. Full coverage also protects your car from damage you cause. Choosing a higher deductible lowers your monthly payment but increases what you'll pay out of pocket if you file a claim. 

See your state's minimum liability car insurance requirements and our guide to determine how much car insurance you need.

*Costs are calculated for a 40-year-old driver with good credit and no driving violations insuring a 2012 Toyota Camry. Maximum coverage refers to a 300/500/300 limit of liability coverage and a $1000 deductible for comprehensive and collision insurance.

Your personal driving history impacts car insurance costs. Driving record violations like accidents, speeding tickets, and serious offenses like DUIs will increase your car insurance rate. If you want to explore rates privately, you can get anonymous car insurance estimates online without providing personal details.

Your credit score affects car insurance rates, and a poor credit score will double your cost. Insurance companies use credit-based insurance scores, their internal equivalent to credit scores, as a rating factor because studies show a correlation between credit scores and claim frequency. Find coverage from these car insurance companies that don't check credit scores if you have poor credit.

Note: California, Hawaii, Massachusetts, and Michigan prohibit insurers from using credit scores in your rate. If you have poor credit, look for companies in these states that don't factor it in.
