How much is car insurance for 21-year-old male and female drivers?

However, some states — California, Hawaii, Massachusetts, Michigan, Montana, North Carolina and Pennsylvania — prohibit insurers from using gender to determine car insurance rates. Men and women should pay the same price for auto insurance coverage in these states, all else being equal.

The average cost of car insurance, by age

The cost of full-coverage car insurance usually decreases with age, and just a few years can result in widely different rates for young drivers. For example, the average 21-year-old pays $384 per month, which is $232 cheaper per month than the cost for an 18-year-old.

Young drivers typically pay more for car insurance compared to older drivers because insurers consider them to be higher risk. This is due to the fact that younger drivers tend to get into more accidents and file more insurance claims.

How to get cheap car insurance as a 21-year-old

The best strategy to find cheap auto insurance as a 21-year-old driver — or a driver of any age, for that matter — is to shop around for rates at different insurers. Insurance companies charge premiums based on many factors, from the car you drive to your driving history. The insurer that offers you the best rate may be very different from those best-suited for your peers or family members.

When shopping around for quotes, 21-year-olds and other young drivers, especially teenagers, can save by staying on their parents' car insurance policies or taking advantage of all available discounts.


Our study pulled quotes from thousands of ZIP codes across nine of the most populated states in the U.S. Our sample drivers were 21-year-old men and women who drove a 2015 Honda Civic EX. The drivers were single and had clean driving records.

We collected full-coverage rates with the following limits:

Coverage type
Study limits
Bodily injury liability$50,000 per person/$100,000 per accident
Property damage$25,000 per accident
Uninsured/underinsured motorist bodily injury$50,000 per person/$100,000 per accident
Comprehensive and collision$500 deductible
Personal injury protection (PIP)Minimum when required by state

Our analysis covered 29 insurance companies. However, an insurer was only added to our list of average prices and recommendations if their policies were available in at least three of the nine states.

ValuePenguin's analysis collected insurance rate data from Quadrant Information Services. The rates used to calculate the averages were sourced publicly from insurer filings. These averages should only be used for comparative purposes — your own quotes may be different.
