Compare the best prices for car insurance
State Farm, Farm Bureau and USAA are the three national insurers that offer the lowest prices on average, but what you’ll pay may vary based on where you live, your driving history and more.
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 traffic violation history, and credit score.
Compare rates by:
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. We compiled the average cost of car insurance for all 50 states and Washington, D.C., and found the cheapest insurer for each.
|State||Cheapest major insurer||Average annual rate||Average monthly rate|

Rates are for state minimum coverage for a 30-year-old male with a good driving history.
Compare car insurance rates by accident history
On average, insurance rates increase by 47% after an at-fault accident. However, not all insurers increase premiums by the same amount.
Drivers insured with Geico see the largest increase in rates after an accident, while State Farm tends to penalize drivers less.
Rate increase after an accident by state
Where you live also affects your car insurance rate after an accident. Drivers in Pennsylvania are fortunate: Their rates only go up by 17% after an accident, on average. Insurance rates in California double after an accident — the highest increase in the nation.

Rates are average annual premiums for full coverage before and after an accident.
Compare car insurance rates by age
Age is a major factor when comparing car insurance rates. Younger drivers pay comparatively more for auto insurance than older drivers because insurance companies consider them to be the riskiest drivers.
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.
- An 18-year-old driver pays an average of $6,777 per year for full coverage car insurance.
- The same driver at 25 years old pays $2,184 per year for car insurance, a decline of 68%.
- But as drivers reach adulthood, rates tend to level out. The same driver pays $1,922 per year at 30 years old, only 12% less than a 25-year-old but easily the lowest car insurance rate of this group.
Car insurance rates generally decline as you age but then spike again in your later years, as senior drivers pose a higher risk than middle-aged drivers.
Compare car insurance rates by credit score
Drivers with excellent credit pay about half as much for car insurance compared to those with poor credit.
Credit scores can 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 pay lower car insurance premiums, while those with poor credit scores tend to pay higher premiums, all else equal.
Annual insurance rates from select insurers for poor and excellent credit ratings
|Insurer||Poor credit||Very good credit||Difference|
Rates are a national average of car insurance policies meeting minimum coverage requirements in all 50 states and Washington D.C.
State Farm provides the biggest discount for excellent credit profiles, decreasing its rates by 69%. On the other hand, Nationwide provides the smallest discount, only decreasing rates by 34% for drivers with an excellent credit history instead of a poor one.
Some states have outlawed the use of credit scores in determining insurance rates. If you live in one of these states, your rates will be the same regardless of your credit score.
