How to compare car insurance plans

Getting a car insurance quote has become a more straightforward process after the growth of online quote tools. But before quote shopping, you'll have to do some legwork to ensure you're making appropriate car insurance price comparisons. Make sure you take the following three steps to compare auto insurance companies:

  • Collect relevant personal information
  • Decide on coverage levels
  • Collect and compare quotes

step 1

Collect relevant personal information before comparing rates


Online car insurance quote tools and insurance agents can provide you with an estimate of your rates, but the estimate will only be as accurate as the information you provide. Make sure you have the following information about you and your vehicle before seeking out a quote.

To obtain an accurate car insurance quote you need the following information:

Your information:
  • full name
  • age
  • address
  • current insurer (and your policy's declaration page)
  • license number
  • equivalent information of any other drivers on the policy
Your vehicle:
  • model (including year and make)
  • vehicle information number (VIN)
  • date of purchase
  • mileage
Your driving history:
  • ticket and accident history
  • any license suspensions

step 2

Decide on fixed coverage levels before comparison shopping

price check

Perhaps the most important factor affecting the price of your car insurance policy is how much coverage you choose to buy. Car insurance policies can include the following types of coverages, and when comparison shopping you should make sure you select the same coverage limits for each. In the cases of collision and comprehensive insurance — which don't have limits — you should ensure you select the same deductibles.

  • Liability coverage (for both bodily injury and property damage)
  • Collision and comprehensive insurance
  • Personal injury protection (PIP)
  • Uninsured/underinsured driver coverage

At the end of this piece, we break down when state law means you need to purchase these coverages (liability insurance is usually required by state law, for example), when they're optional and how much of them we recommend should buy.

When you compare vehicle insurance online across multiple insurers, the most important thing is that you keep these coverages and their limits consistent with each insurer. Then you can compare auto insurance quotes side by side knowing that your coverage will be equivalent.

step 3

Collect and compare quotes


Once you have all your personal information and have decided on appropriate coverage limits, it's time to shop. If you're looking to compare cheap car insurance, you can use our insurance comparison tool at the top of the page. Or you can go to multiple insurer websites, use their quote tools and compare quotes from different companies. A good place to start are our recommendations for the best and cheapest car insurance companies below.

Comparing factors that affect car insurance rates

The primary factor that affects car insurance rates is the amount of coverage you select. But beyond your elected coverage, many variables will affect your rates including your age, location, vehicle type, accident and violation history and credit score.

We took a sample driver and altered his location, characteristics and driving history to create a comprehensive car insurance price comparison analysis. These quotes apply to our sample driver and should serve as a guide rather than a prediction of what your auto insurance rates will be.

Compare car insurance rates by state

Insurance is regulated on a state level, and comparing auto insurance rates by state can show how drastically state regulations affect the price of car insurance where you live. Below, we've ranked the 50 states and Washington, D.C., from cheapest to most expensive for a sample policy.

Policy with comprehensive and collision insurance

RankStateAnnual premium
Rates are for a full coverage policy as detailed in our methodology at the bottom of the page.

Comparing the cheapest state, Maine, where our sample driver is charged $1,268 per year, to the most expensive state, Michigan, where our sample driver is charged $8,723 per year, shows the potential range in quotes. Note that car insurance prices in your area may vary significantly.

The rates here are for a policy with comprehensive and collision insurance, but what if you just want a policy that only meets your state's minimum requirements? In any individual state, this would be the cheapest auto insurance policy you can get. Next, we compare car insurance rates by state for policies that only meet the respective state minimums.

Compare car insurance rates by age

Age is a major factor when comparing car insurance rates. Younger drivers — considered the riskiest drivers, according to insurance company calculations — pay comparatively more for auto insurance than older drivers, all else equal.

Taking three specific ages as an example: 18, 25 and 30, you can see how insurance rates change over the course of the average young adult's driving life.

  • Our sample 18-year-old driver pays an average of $7,179 per year for car insurance.
  • The same driver at 25 years old pays $3,207 per year for car insurance, a decline of 55%.
  • But as drivers reach adulthood, rates tend to level out. The same driver pays $2,399 per year at 30 years old, only 25% less than a 25-year-old, but easily the lowest car insurance rates of this group.

Our graphic below shows how average auto insurance rates compare for ages ranging from late teens to 30 years old. Car insurance rates generally decline as you age but then spike again in your later years, as senior drivers are thought of as riskier than middle-aged drivers.

Compare car insurance rates by credit score

Credit scores can also be a key factor in determining your auto insurance quote. Insurance companies use a proprietary calculation — called a credit-based insurance score — to rate their customers. Policyholders with good credit scores tend to be offered lower car insurance premiums, while those with poor credit scores tend to be offered higher premiums, all else equal.

We found that drivers with excellent credit can save an average of 35% off their premium compared to those with poor credit. Below, we compare average annual insurance rates for 13 major insurers, showing how annual rates change between the same drivers if they have either poor or excellent credit.

  • Farmers provides the biggest discount for excellent credit profiles, decreasing its rates by 54%.
  • Metropolitan (or MetLife) provides the smallest discount, only decreasing rates by 12% if our sample driver had an excellent credit history instead of a poor one.

Rates are a national average of car insurance policies meeting minimum coverage requirements in all 50 states and Washington D.C.

Some states have outlawed the use of credit scores in determining insurance rates. If you live in one of the following states, the quality of your credit score will not affect your car insurance rates.

  • California
  • Massachusetts

How to estimate how much car insurance you need

Before you begin insurance shopping, you'll have to decide on fixed coverage levels so that you can make like-for-like comparisons across auto insurers. Below, we've provided a quick cheat sheet for how much state law may require you to buy — and how much we recommend you actually do buy — of the main coverages offered in a car insurance policy. Ultimately, the choice is up to you in balancing the expense of increased coverage with the comfort of more protection.

Liability insurance

  • What is it?

    Liability insurance covers the cost of bodily injury or property damage to others if you're at fault in an accident.

  • Do you need it?

    Unless you live in New Hampshire, yes. Every other state, and Washington, D.C., requires some degree of liability protection.

  • How much should you have?

    Requirements for minimum coverage limits differ by state. Regardless, a good rule of thumb is to buy per accident bodily injury liability limits high enough to cover your net worth. That means, if you're at fault in a major crash, you have sufficient coverage to protect you against the cost of injuries to others.

Comprehensive and collision insurance

  • What is it?

    Collision insurance covers damage to your car that happens on the road, whether it's an accident involving another vehicle or with an inanimate object. Comprehensive insurance covers damage to your car that comes from events unrelated to driving, such as theft or weather damage.

  • Do you need it?

    If you lease a car or borrowed money to finance the purchase, your lender will likely require you to buy this insurance. If you purchase a car on your own, you aren't required to buy these coverages, but we recommend getting them if the value of your car exceeds $3,000.

  • How much should you have?

    Comprehensive and collision insurance don't have limits. Instead, your insurer will cover the damage to your car up to its actual cash value, minus your deductible.

Personal injury protection (PIP)

  • What is it?

    Covers the medical costs of injury to you or your passengers in an accident, regardless of fault. It also covers the cost of missing work if an injury leaves you incapable of working for some period.

  • Do you need it?

    12 states require some form of PIP: Florida, Hawaii, Kansas, Kentucky, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Oregon and Utah. Residents of the remaining states are not mandated to buy PIP. Many health insurance policies may cover your medical costs after an accident, but PIP also offers coverages for lost wages related to an injury.

  • How much should you have?

    If you're not in a state with PIP requirements and you have health insurance, we recommend you buy PIP if your health insurance does not cover auto-related injuries or if you want coverage for lost wages. If you don't have health insurance, we advise working with an insurance agent to purchase an affordable amount of PIP to protect you against the cost of injury to yourself in a crash.

Uninsured or underinsured motorist insurance

  • What is it?

    Covers property damage or bodily injury to you or your passengers if another at-fault driver has insufficient insurance to cover the costs (underinsured motorist insurance) or if the driver has no insurance at all (uninsured motorist insurance).

  • Do you need it?

    About half the states in the country require uninsured and/or underinsured motorist insurance. If you're not in one of those states, we recommend buying this coverage for two reasons. The first is that it's usually quite affordable. The second is that one in eight drivers in the U.S. is uninsured, leaving you and other drivers at risk.

    However, drivers who have PIP and collision and comprehensive insurance don't need uninsured or underinsured motorist insurance. These coverages protect you against the cost of bodily injury or damage to your car, so they overlap with uninsured or underinsured motorist coverage.

  • How much should you have?

    We recommend purchasing limits for these coverages in a similar amount to your bodily injury and property damage liability coverage limits.

We gathered rates through 50 states and Washington, D.C., for 51 insurance companies. To ensure some level of availability for our recommendations given differing state insurance markets, an insurer is only noted in the lists above if it is available in at least five states.

Our sample driver was a 30-year-old male who drove a 2015 Honda Civic EX, and rates used all available ZIP codes in each state. The driver was profiled as having no credit history, which makes him equivalent to a driver with below-fair to poor credit, according to our data source, Quadrant Information Services.

When our driver had a full coverage policy, we gave him coverage limits slightly above any one state's minimum requirements.
