Why Car Insurance Is Expensive for 21-Year-Olds

Age significantly impacts car insurance rates. Young drivers, usually under 25, typically pay more due to their lack of driving experience and statistically higher risk of accidents.

As drivers grow older and gain experience, their risk lowers, leading to reduced insurance costs. Insurance rates often decrease markedly after the age of 25.

Contrary to popular belief, car insurance premiums can decrease after just one year of driving, assuming you haven't upgraded to a more expensive car or had a moving violation. However, it's after turning 25 that you typically exit the high-risk category for insurers, leading to more significant rate reductions.


Car insurance rates typically do not decrease significantly at 21. While there may be a minor reduction compared to teenage years, substantial decreases in premiums generally occur after age 25 when insurers no longer categorize these drivers as high-risk for age alone.

At 21, factors like driving history and vehicle type continue to play a crucial role in determining insurance costs.

Cheapest Car Insurance Companies for 21-Year-Olds

The cheapest car insurance companies for 21-year-old male drivers are:

  • Nationwide: $1,582 per year, $132 per month
  • GEICO: $1,745 per year, $145 per month

Until they reach 25, male drivers often pay more for car insurance than their female counterparts. However, they can still secure cheap car insurance by comparing offers.

Insurance companies have distinct pricing models, leading to varied rates for each policyholder. In some states like Hawaii and California, insurers are not allowed to base rates on age or gender, offering more equalized pricing options.

Average Cost of Car Insurance for 21-Year-Olds in an Individual Policy vs. Family Policy

For 21-year-old drivers, getting car insurance through a family policy offers substantial financial benefits. The cost of an individual full coverage policy averages around $3,839 per year, whereas the same coverage under a family policy is much lower at $1,953 annually. 21-year-old students can stay on a family policy, even if they are away at college, as long as the family residence is their permanent address.

This substantial cost saving is a significant advantage. However, the downside is the potential impact on the family’s premium if the young driver has an accident or traffic violation.

Additionally, a family policy might limit the independence of the 21-year-old, as they are not the primary policyholder, potentially affecting future insurance creditability and personal premium rates.

What Affects the Cost of Car Insurance for 21-Year-Olds

Credit history, driving history and chosen coverage significantly impact car insurance costs for 21-year-olds.

    car2 icon

    Driving experience and history

    For 21-year-old drivers, limited driving experience can lead to higher premiums. A clean driving record, however, can mitigate this factor, signaling responsible driving behavior to insurers.

    pickupTruck icon

    Type of vehicle

    The car a 21-year-old drives impacts insurance costs. High-performance or luxury vehicles generally result in higher premiums due to higher repair costs and increased theft risk.

    car icon


    Geographic location affects rates, with urban areas typically having higher premiums due to increased traffic and accident likelihood.

    male icon


    Male drivers aged 21 often face higher premiums than females, reflecting statistical differences in driving risk and accident rates.

    carInsurance icon

    Coverage level

    Choosing higher coverage limits or additional options like collision and comprehensive insurance increases premiums but provides broader protection.

    money icon

    Deductible amounts

    Opting for higher deductibles can reduce the monthly premium cost. This means the driver will pay more out-of-pocket in an accident before insurance kicks in. Collision and comprehensive coverages are subject to separate deductibles, but liability coverage is not subject to a deductible.

    goodCredit icon

    Credit score

    In most states, a better credit history can lead to lower insurance rates, as insurers view a good credit record as indicative of responsible financial behavior.

    graduationCap icon

    Educational status

    Students with good academic records may qualify for discounts, as insurers often correlate good grades with responsible driving behavior. Many insurers also offer distant student discounts for students who are away at school without a car.

    Insurance company

    Each insurer has unique underwriting methods for calculating premiums, meaning rates can vary significantly between companies. Shopping around helps you find the best deal.

How to Find Cheap Car Insurance for 21-Year-Olds

While car insurance for 21-year-olds can be pricey, you can effectively reduce costs by staying on a parent's policy, comparing quotes and opting for a practical, safe car.

    Stay on a parent's policy

    Remaining on a parent's policy can be cheaper than having an individual policy, especially if the parent has a good driving record. 21-year-old students can remain on the family's policy as long as the family home is still their permanent address.

    Compare quotes

    Shop around and compare quotes from multiple insurers to find the most competitive rates for 21-year-olds.

    Choose a practical car

    Opt for a vehicle that's cheaper to insure, such as a used car with good safety ratings, rather than high-performance or luxury models.

    money2 icon

    Increase deductibles

    Consider raising your deductibles for collision and comprehensive coverages (liability coverage does not include a deductible), which can lower your premium, but ensure you can afford the out-of-pocket cost in case of a claim.

    carAccident icon

    Maintain a clean driving record

    Avoiding accidents and traffic violations can help you qualify for lower rates due to reduced risk.

    Use telematics programs

    If available, participate in your insurer's telematics program, which tracks driving behavior and can lead to discounts for safe driving. State Farm's Steer Clear telematics program, for example, is specifically designed for drivers under 25. However, keep in mind that some insurers could raise your rates if telematics tracks poor driving habits.

    discount icon

    Seek out discounts

    Ask about discounts for good students, distant students, defensive driving courses or low mileage, which are often available for younger drivers.

    financialPlanning icon

    Bundle policies

    If you have other insurance policies, such as renters' insurance, bundling them with the same provider can offer additional savings.

    carInsurance icon

    Review coverage needs

    Ensure you're not over-insuring by reassessing your coverage needs, but don't skimp on essential coverage for the sake of cost.

    Build credit wisely

    Improve or maintain a good credit score, as insurers often use credit history to determine premiums.

Finding the Best Car Insurance Coverage for 21-Year-Olds

Secure mandatory liability coverage beyond minimums, opt for comprehensive coverage for newer cars and tailor deductibles to align with your budget and risk tolerance.

    accident2 icon

    Mandatory liability coverage

    Ensure you have state minimum car insurance requirements, which most states require by law. It covers damage and injuries you may cause to others. Given the risk profiles of young drivers, consider opting for higher liability limits beyond state minimums.

    car2 icon

    Assess vehicle value and usage

    Comprehensive and collision coverage can be beneficial if you have a newer or higher-value car. These cover your vehicle in events like accidents or theft, especially if you park your car on the street.

    carInsurance icon

    Balance deductibles and premiums

    If budget constraints are a concern, a higher deductible can reduce your monthly premium. However, this means more out-of-pocket expenses in an accident — conversely, a lower deductible results in a higher premium but less financial burden during a claim.
