Adding a teen driver typically raises a family’s auto premium by $1,400 to $3,700 a year depending on the source, with CarInsurance.com’s 2026 report putting the average at $3,721, a 125% jump, and Bankrate-based figures showing a 16-year-old can more than double a couple’s bill. The catch is that a separate policy for the teen usually costs far more than adding them to a parent’s, and discounts such as good student typically trim only about 7% to 12%.
Key Takeaways
- CarInsurance.com’s 2026 State of Auto Insurance Report says adding a teen raises the average family premium by $3,721 a year (125%), from about $4,354 in Vermont to $7,122 in Louisiana
- Bankrate data cited by Trucordia puts full coverage for a 16-year-old on a parent’s policy at $5,740, adding about $3,225 to a couple’s $2,515 premium, while USAA says the average increase is about $1,400
- A standalone policy for a 16-year-old can cost much more, for example $10,321 a year for a 16-year-old male, against $4,856 added to a parent’s policy
- Good student discounts average about 7% (Insurance.com via South Carolina DOI) to 12% (CarInsurance.com), and student-away discounts run about 5% to 10%
- Per mile driven, 16- to 19-year-olds have the highest crash rate of any age group except drivers over 80, and premiums fall about 24% at age 19
Why Is Teen Insurance So Expensive?
Trucordia says teen insurance is expensive because teen drivers crash more, and that per mile driven 16- to 19-year-olds have the highest crash rate of any age group except drivers over 80. The Insurance Institute for Highway Safety, as quoted by Autoblog, says per mile teens are three times more likely than drivers age 20 and older to be in a fatal crash. The South Carolina Department of Insurance, summarizing Insurance.com research, says 16-year-olds have a crash rate twice that of 18- and 19-year-olds, which is why insurers price the youngest drivers highest.
Should Your Teen Have Their Own Policy?
CarInsurance.com says if a teen will drive, they need a policy, either their own or as a driver on yours. It compares a standalone cost with the cost of adding the teen to a parent’s policy and lists $9,825 a year for a 16-year-old and $5,470 for a 19-year-old on their own, against $4,856 and $4,116 added to a parent’s policy for 16- and 19-year-old males. USAA likewise says a separate policy for a 16-year-old could cost substantially more, and notes the day a teen passes the test they must be added to your policy.
| Option | Reported Cost | Key Catch |
|---|---|---|
| Add to parent’s policy | About $1,400 (USAA) to $3,721 (CarInsurance.com) more per year | Varies widely by state and carrier |
| Teen’s own policy | $9,825 at 16 and $5,470 at 19 (CarInsurance.com) | Usually costs far more |
| Full coverage on teen added to a couple | $5,740 versus $2,515 before (Trucordia, via Bankrate) | More than doubles the premium |
| Premium decline with age | About 24% at age 19 | Risk falls as driving history builds |
What Discounts Are Available?
The South Carolina Department of Insurance says a good student discount requires about a B (3.0) average and, per Insurance.com, saves about 7% or $361 on average, while a student-away discount can save around 5% to 10%. CarInsurance.com says good student discounts average around 12% and suggests asking about discounts for safety features, strong grades and teen driving programs. Motley Fool cites around 10% for good grades, adding that a safer used sedan and telematics can reduce rates. USAA says discounts are available for driver training, good grades and safe driving programs.
How Do You Manage the Cost?
- Choose the car: Motley Fool advises a used sedan with solid safety scores over a sporty model
- Use telematics: some programs monitor speed, braking and mileage for discounts
- Raise liability limits carefully: Trucordia recommends $250,000 per person and $500,000 per accident in bodily injury liability
- Compare carriers: costs and discounts differ by insurer
- Revisit yearly: premiums fall as the teen gains experience
What Does Graduated Licensing Add?
AutoGuide, summarizing the IIHS, says the institute calls at least 70 hours of supervised driving a best practice for graduated driver licensing and recommends no teen passengers in the intermediate stage and a nighttime restriction starting at 8 p.m. Those risk factors are what insurers price in when a teen joins a policy. Following your state’s licensing rules is also a safety measure, not just a legal one.
