Factors That Affect Car Insurance Calculator.

Car insurance prices are set based on how likely it is you’ll make a claim. Here’s what companies look at:

  • Driving record: If you’ve had accidents or gotten tickets recently, your rate might go up.
  • Age: Younger drivers, like teens, usually pay more because they have less experience.
  • Where you live: Busy areas with more people and cars can mean higher rates because there’s a bigger chance of something happening.
  • Your car: Safe cars might cost less to insure. But if your car is fancy or high-tech, it could cost more.
  • Household drivers: Adding or removing drivers from your policy can change the price.
  • How much you drive: If you don’t drive a lot, you might pay less.
  • Credit history: In most states, a lower credit score might mean a higher insurance price.
  • Coverage choices: If you choose to have more protection, it’ll cost more. But if you go for a higher deductible (the money you pay before insurance kicks in), it can lower your rate.
  • Discounts: Different companies offer different deals. Some might suit you better and save you money.

How to calculate how much car insurance coverage you need

When shopping for car insurance, you should know the parts of a policy. A usual policy might have six main parts:

  • Comprehensive coverage: Covers damages not from crashes, like weather or theft.
  • Collision coverage: Pays for damages from accidents with cars or objects.
  • Uninsured and underinsured coverage: Protects you if hit by someone without enough or any insurance.
  • Auto liability coverage: Covers costs if you’re at fault in an accident.
  • Medical payments coverage: Helps with medical costs from car accidents.
  • Personal injury protection: Pays for medical and other costs, like lost wages, no matter who’s at fault.

Remember, comprehensive and collision are optional unless a lender or lease company says you need them. You can mix and match to create a policy that fits your needs and budget.

Comprehensive and collision coverage overview

Collision and comprehensive insurance both protect your car from damage. Here’s how:

  • Collision: Covers your car if you hit another car or object.
  • Comprehensive: Covers damages from things like weather, animals, or someone damaging your car on purpose.

Together, they’re often called “full coverage.”

States don’t force you to have them, but if you’re paying off a car loan or leasing, you might need to get them. For both, you’ll pay a deductible first, and then your insurance helps with the rest.

Underinsured/uninsured motorist coverage

If the driver who causes a crash doesn’t have insurance or doesn’t have enough, uninsured and underinsured coverage helps pay for the damages. There are two main types:

  • Uninsured property damage: Covers costs for damage to your car.
  • Uninsured bodily injury: Helps pay medical bills if someone gets hurt.

How car insurance calculator premiums

Car insurance companies use a driver’s profile to determine the cost of their policy. This profile has many factors, including:

How car insurance calculator premiums
  • Driving record: A clean history can lower your rates.
  • Type of car: Some cars are cheaper to insure.
  • Location: Where you live can affect rates.
  • Age, gender, and marital status: These can influence your cost.
  • Credit score: A higher score might get you a lower premium.
  • Insurance and driving history: Past details can impact current rates.

The less risky you appear to the insurance company, the cheaper your policy. Now, let’s explore how each factor affects your insurance cost.

Demographics and auto insurance rates

Insurance companies consider factors like age, gender, credit score, marital status, and whether you own a home. They use these details to gauge the risk you pose and set your insurance rate.

Credit score

In states where credit scores can influence insurance rates, your credit history affects your premiums. Drivers with good credit often get lower rates since data suggests they file fewer claims compared to those with poor credit.


Teens and seniors typically have the highest insurance premiums because they’re statistically more prone to accidents. Rates for these groups are often higher than for drivers aged 25-60.

Marital status

Single drivers, according to industry data, have double the risk of injury in accidents compared to married ones, affecting insurance rates. If you’re married, your spouse’s driving record can impact your premiums. A good record might lower costs, while a risky one could raise them.


Insurance companies often consider gender more for young drivers than for older ones. Typically, a male teen driver pays about $754 more annually than a female teen driver. This is because young males are viewed as riskier drivers compared to females. 

Location and car insurance rates

Each U.S. state regulates auto insurance, and prices are determined by a driver’s ZIP code. If a state mandates higher basic coverage, its residents might pay more for insurance.


Car insurance rates vary by ZIP code, reflecting the unique risks of each area. Places with more drivers, or where floods, wildfires, crime, or other hazards are common, tend to have higher rates. Typically, rural residents pay less than those in urban areas.

Additional coverages required by state

In “no-fault” states like Florida, drivers must have personal injury protection (PIP) coverage, which can be pricier. This makes car insurance in Florida more expensive compared to many other states. Within specific ZIP codes, if there are more claims, insurance rates might rise due to the higher accident risk and the chance of bigger payouts.

Insurance history and insurance pricing

Insurance companies favor drivers with consistent insurance records. Gaps or inconsistencies can raise concerns. Drivers with a history of high insurance limits are viewed as financially responsible, making them less risky compared to those without a solid insurance background.

Driving history

Car insurance companies use a driver’s past as a gauge for future behavior. A history of tickets or violations will increase the cost of insurance premiums.

Vehicle choice

Insurance for a new sports car will cost more than for an older Civic. The more expensive a car is to replace, the higher the monthly insurance fee to account for potential losses. Insurance providers also consider if you own, finance, or lease your vehicle when setting rates. Check out rates by vehicle type.

Insurance history

Insurance companies view a gap in continuous coverage as a potential sign of increased risk, particularly for individuals with established driving histories. From their perspective, if you held a driver’s license but do not maintain insurance, it could suggest a driving period without adequate coverage.

Coverage levels and insurance pricing

The cost of your insurance premiums tends to rise in proportion to the extent of coverage you choose. This cost disparity between minimal and extensive car insurance coverage can exceed $1,000 per year. This phenomenon is rooted in a straightforward principle: when you opt for more extensive coverage, your insurance provider assumes a greater obligation to pay out to meet the higher coverage limits.

Liability only vs full coverage

Full coverage insurance incorporates comprehensive and collision protections, components typically absent in liability-only policies. Consequently, opting for full coverage results in higher premiums due to the inclusion of these additional safeguards.

Deductible amount

Moreover, your insurance premium is influenced by the deductible amount you choose. Opting for a higher deductible reduces your insurance rates but entails a greater out-of-pocket expense in the event of an accident.

Why some cars cost more to insure

The cost of insuring certain vehicles can vary significantly because insurance providers analyze crash and theft statistics to determine rates for individual car models. Consequently, if the car you select has a history of being stolen or involved in accidents, you can expect higher insurance premiums. For example, sports cars tend to be pricier to insure due to their propensity for high-speed driving and more severe accidents.

Several specific characteristics of a vehicle influence auto insurance costs, including:

Why some cars cost more to insure
  • Retail price: In general, the more expensive the car, the higher the insurance costs. This is especially relevant when purchasing comprehensive and collision coverage, as insurers would need to pay out the car’s market value if it’s stolen or declared a total loss in an accident.
  • Cost of parts: Luxury and high-end models often utilize specialized materials like carbon fiber, which are costly to repair or replace. This contributes to increased expenses for damage claims.
  • Safety: Vehicles that excel in protecting both drivers and passengers over time tend to lower insurance costs. Fewer injuries result in fewer claims for medical payments and personal injury protection, reducing overall insurance expenses.

How to save on car insurance premiums

Although some rating factors are beyond your control and challenging to alter, there are several steps you can take to ensure that you secure the most favorable insurance rate for your circumstances. To help reduce your insurance expenses, consider the following steps:

Compare quotes with multiple companies

Insurance comparison platforms like The Zebra analyze rates from a multitude of insurance companies while considering your individual requirements and rating factors. By obtaining multiple quotes from various insurers, you can determine which company can provide you with the most affordable rate tailored to your specific situation. The Zebra has curated a collection of resources to assist you in obtaining car insurance quotes from the nation’s leading companies. For further insights on quotes and securing the right policy, we recommend reviewing their comprehensive guide to car insurance quotes.

Inquire about discounts

Virtually all insurance providers provide a roster of potential discounts that you might be eligible for in order to reduce your premium expenses. Familiarizing yourself with the discounts offered by insurers and determining which ones are applicable to your situation can help you avoid higher premium costs.

Bundle your policies

If you require additional insurance coverage such as homeowners, renters, or mobile home insurance, combining another insurance product with your auto insurer presents a convenient avenue for reducing your premiums. Multi-policy discounts typically offer some of the most substantial discount percentages accessible in the insurance realm.

Improve your driving record

You directly influence one of the more straightforward rating factors – your driving record. You can enhance your driving record by adhering to safe driving practices and steering clear of traffic violations. This, in turn, signals to insurance companies that you represent a reduced risk, ultimately leading to lower premium costs.

Improve your credit score

Like your driving record, your credit score is one rating factor that is within your control. Paying bills on time and increasing your credit score will lower car insurance rates.
