When drivers reach age 21, car insurance rates typically drop by around 16% compared to teen drivers.
The average cost of car insurance for a 21-year-old in the U.S. is $154 per month for liability-only insurance and $292 per month for full coverage, according to Insurify data.
By staying on a parent’s policy, a 21-year-old driver saves an average of $29 per month on liability-only car insurance and $55 monthly for full coverage.
Average car insurance rates at age 21
On average, 21-year-old drivers in the U.S. pay $1,848 annually for liability-only car insurance and $3,504 per year for full coverage. But rates vary widely depending on factors like the driver’s location and gender.
Young men often pay higher rates than women because they drive more and tend to engage in riskier driving behaviors, leading to more accidents.[1]
Location affects factors like accident and vehicle crime rates. The cheapest state for a 21-year-old driver is Wyoming, where liability-only coverage costs $960 per year on average, according to Insurify data. Rhode Island is the most expensive state for 21-year-olds, at $3,540 annually.
Staying on a parent’s policy is one way 21-year-olds save money on car insurance. Drivers save $348 per year, on average, for minimum coverage and $660 per year on full coverage by using this strategy.
The following table compares average monthly minimum-coverage and full-coverage rates for 21-year-old drivers.
Coverage Level | Average Monthly Quote: 21-Year-Old Driver |
|---|---|

Car insurance rates for 21-year-olds by gender
Gender is a significant rating factor insurers consider when setting premiums. Young men generally pay more than women for car insurance because they pose more risk to insurers.
The average monthly rate for 21-year-old male drivers is $156 for liability-only insurance and $297 for full coverage, according to Insurify data. Women in this age group pay an average of $151 and $288 per month, respectively.
That means male drivers pay $60 more per year for liability-only coverage and $108 more for full coverage, reflecting a 3% difference between genders in this age group.
California, Hawaii, Massachusetts, Michigan, Montana, North Carolina, and Pennsylvania prohibit the use of gender as a factor in setting car insurance rates.[2] The following table illustrates the cost difference for 21-year-old drivers based on gender.
Coverage Type | Average Monthly Rate: Male | Average Monthly Rate: Female |
|---|---|---|
| Liability only | $156 | $151 |
| Full coverage | $297 | $288 |
Should you stay on your parent’s policy at 21?
In most cases, staying on your parent’s car insurance policy for as long as possible is the most affordable option. On a separate policy, the average cost of car insurance for 21-year-old drivers is $154 per month for liability coverage and $292 per month for full coverage.
Drivers in this age group save an average of 23% when they can stay on their parent’s policy.
If the car title contains your parent’s name or both of your names, then you can typically stay on the family car insurance policy. This may be true whether you’re living at home, you’re away at college with your car at home, or you take your car to college with you.
But you’ll usually need to buy your own policy if only your name is on the title. And if you no longer live with your parents, you’ll need your own policy. In any situation, it’s best to check the rules with your car insurance company.
Agent Tip: Should you stay under your parents‘s policy?
“Young drivers who stay on their parents’ policy get the benefit of some price breaks they might not qualify for on their own, like a bundling discount, homeowner discount, and lower rates for good credit and continuous coverage.”

How to save on car insurance at 21
Car insurance tends to become more affordable as you gain driving experience, but 21-year-olds can still take steps to lower their premiums. Consider these ways to save:
Compare options. Get quotes from three to five insurers, especially if you’re transitioning off a parent’s policy.
Evaluate your coverage needs. For instance, you might want roadside assistance if you’re driving to and from school. On the other hand, collision and comprehensive coverage may not be worth the cost if you drive a paid-off, older car with a low value.
Raise your deductible. This can help lower your premium, but make sure you can comfortably cover the higher out-of-pocket cost after a claim.
Shop for coverage as your needs change. You may need different types of coverage after major life events like graduating from college, getting married, moving, and having kids.
Ask about discounts. One of the best ways to lower your premium is by qualifying for discounts, such as those for good students, safe drivers, and bundling multiple policies.
