Auto Insurance Rates By State; Least & Most Expensive to Insure

Are you currently insured?
Yes No

Most think it’s quite unfair for a driver to pay twice the amount for a car insurance premium in one state verses another.

How is this happening?

While most drivers know your age and driving history determines how much you pay for car insurance.

Another chief factor is the state you reside in.

Average car insurance rates vary by state based on regulations while insurance companies give you a price quote based on those differences.

And one state may have higher instances of claims while another doesn’t.

Most and least expensive state to buy an auto policy illustrated.Note: States at the top of the graph have an average car insurance premium of $2,000+ for a full coverage policy. The bottom states have an average policy price of $1,000. If you live in Michigan, Louisiana or Florida you will pay more than double for an auto insurance policy compared to residing in Maine, Iowa or Ohio.

This, too will affect how much you will pay for your car insurance premium.

Below we have laid out the average car insurance by state.

Read on so you have an idea what you are going to pay for an auto insurance premium in the area of country you reside.

Least Expensive States for Car Insurance

The states with the cheapest auto insurance rates for 2020 are Maine, Iowa, Idaho and Ohio.

Year over year premiums for each state is going up.

However, each of the 4 states have an average annual premium around $950.

Which is nearly 35% lower than a nationwide average of nearly $1,400.

Below is a list of the least expensive states:

North Carolina$1,158$700$272$186
New Hampshire$1,348$789$358$201


The average car insurance premium for Maine is $910 per year.

One of the primary reasons is Maine has a low amount of uninsured drivers.

Further, there are less people which means less congestion and less likelihood for drivers to file claims.

If you have a good driving record and live in Maine, you will pay less for a premium than other drivers throughout the U.S.

Below are insurers offering quotes for a 30 and 45-year-old driver.

Company30 Year Old45 Year Old
Vermont Mutual$1,265$801


Drivers in Iowa are going to pay approximately 30% less for car insurance than the average national premium.

Iowa drivers, with a good driving history, can pay $955 per year for full coverage.

The biggest contributing factor for low premiums in Iowa is the large rural to urban ratio.

At the end of the day, if you have less drivers driving on congested roads you have less accidents.

And you will have less drivers filing claims which means lower premiums.

Company30 Year Old45 Year Old
Western National$1,188$732
Hastings Mutual$1,243$824


Idaho’s average premium is approximately $1,020 per year.

Or nearly 28% lower than the national average.

Idaho benefits from low premiums since the uninsured motorist rate is only 8%.

And, according to research, a large percentage of drivers in Idaho are 55 and up.

In the largest city, Boise, a car insurance premium is going to be slightly higher.

On the other hand, drivers in Boise have shorter commutes which means they drive less, which means lower premiums.

Below are quotes for drivers residing in Boise. 

Company30 Year Old45 Year Old
American National$1,231$754
Mutual Enumclaw$1,312$821


Ohio’s average premium is $1,024 and unusually low compared to the rest of the U.S.

One the contributing factors is Ohio’s tort-based insurance system.

A tort system is the opposite of a no-fault state where one driver is found at fault and their insurer pays the medical fees.

Essentially there is a lack of a safety net.

And because of this, auto insurance rates are lower in Ohio.

Below are sample quotes for drivers with a clean record:

The Cincinnati$1,265$746


Wisconsin auto insurance rates are lower than average with an average premium of $1,050.

South Dakota$1,530Wisconsin$1,050

Your auto insurance rate is going to be decided by many other factors such as your age and the type of vehicle you drive.

If you want cheap auto insurance it is important to take advantage of factors insurers use to lower your overall premium. 

Vehicle Type

Though you may live in an expensive or cheaper state, the type of vehicle you drive can make a substantial impact on your car insurance premium.

For example, if you live in Michigan, the cost to insure a Honda Civic is $3,094 while a BMW 640i cost over $4,100.

Below are sample quotes of each vehicle for a driver in Michigan:

 Honda Civic EXBMW 640iGMC Yukon
30 Year Old$3,046$4,180$2,674
45 Year Old$2,278$3,287$1,895

As you can see, if you switch from driving a BMW to Chevy Yukon you can save over $1,500 per year in Michigan.

Let’s take a look at Maine, the cheapest state.

If we use the exact vehicle the premium drops substantially.

However, the difference in price among cars isn’t as significant either.

Take a look at the sample quotes below: 

 Honda Civic EXBMW 640iGMC Yukon
30 Year Old$954$1,596$1,111
45 Year Old$629$952$703

In Maine you have more financial freedom to drive the car you want.

In Michigan, unless you are wealthy, you will choose a vehicle based on its features plus the cost to insure it.

Coverage by State

Of course you want to get a premium which is lower than the average price.

On the other hand, the insurer you choose to get a policy from is going to determine how much you pay for car insurance premium in each state.

Below we have itemized the least expensive companies by state.

The insurance companies listed are ones we found offering coverage lower than the average premium.

Your premium is going to be determined by many factors.

The type and amount of coverage will influence your premium.

For example, the difference between full coverage and minimum liability will be significant.

Many states require you to have personal injury protection or PIP and medical payments coverage.

This too will influence your final premium.

Further below we will explain personal injury protection and medical payments coverage.

Personal Injury Protection (PIP)

Personal injury protection, sometimes called PIP, is the portion of your policy that provides medical expenses and work-loss coverage for you and your passengers in the event of a vehicle accident.

PIP covers you no matter who is at fault.

Here are items PIP will cover:

  • Medical bills
  • Surgical fees
  • Lost wages
  • Rehabilitation fees

And if you live in any states below you will be required to carry PIP along with liability coverage:

State PIP Coverage
New Jersey$15,000
New York$50,000
North Dakota$30,000

As you can see, many expensive states to insure a vehicle are on the list.

Since you are required to carry PIP in the listed states your overall car insurance premium will be higher than average. 

Basic policy breakdown by coverage type. Bodily injury, property damage, medical payment, and uninsured motorist.Note: Illustrated above is a breakdown of a policy. The area we are referencing too is the “medical payment” part of the policy. Some states require you have medical payment (MedPay) or personal injury protection (PIP). If you are required by your state to carry either coverage it makes up a significant portion of your policy. And in turn raising your car insurance premium.

Next, we will explain medical payments coverage and the slight difference from PIP.

Medical Payments Coverage

Medical payments coverage, sometimes called MedPay, is intended to cover medical costs in the event of any accident no matter who is at fault.

Normally, your health insurance coverage will pay for necessary medical expenses.

MedPay will “fill in the gaps” for cases where there are low limits or high deductibles.

The difference between MedPay and PIP is Personal Injury Protection takes it a step further and covers lost wages where MedPay doesn’t.

MedPay coverage is required in the following states:

  • Pennsylvania
  • Maine
  • New Hampshire

Medical payments cost less the PIP for the same coverage.

To get $10,000 in medical payments coverage you will pay from $4 to approximately $24 per month.

For example, in Maine the minimum medical payments coverage is $2,000 which will cost $8 a month or thereabouts.

PIP coverage normally has higher required limits and will cost more.

In Florida, PIP coverage is $10 to $15 a month depending on the deductible.
