How much does car insurance go up when you add a teen driver? Usually by a lot, but there's no single number that applies to every family. The increase depends on your insurer, your state, the cars you own, the coverage you carry and your teen's age and record. Insurers charge more because teens are the highest-risk drivers on the road. The good news is that several choices are within your control. Discounts, the car your teen drives, your deductibles and shopping around can all bring the cost down.

This guide explains why the jump happens, what published data says about teen risk, and how to get an accurate quote and reduce it. We don't quote a national "average increase," because the regulators and consumer groups we rely on don't publish one. Your own quote is the only number that matters, and the steps below help you get the best one.

Why adding a teen raises your premium

Insurers price your policy on the expected cost of future claims. For teen drivers, that expected cost is high.

According to the CDC, the risk of motor vehicle crashes is higher among teens ages 16 to 19 than among any other age group. Drivers in that age group have a fatal crash rate almost three times as high as drivers 20 and older per mile driven. Risk is highest in the first months after getting a license. The CDC says the crash rate per mile for 16-year-olds is about 1.5 times that of 18- and 19-year-olds.

Consumer Reports, citing federal highway safety data for 2023, notes that drivers 20 and under were only 5.1 percent of licensed drivers but 8.9 percent of drivers in fatal crashes and 12 percent of drivers in all crashes.

The CDC also lists factors that raise teen risk further: being male, carrying teen passengers, driving at night and on weekends, not wearing seat belts, distraction, speeding and impairment. Some of those factors show up directly in pricing. Others, like a ticket or crash, show up on the teen's record and affect future renewals.

How much will my car insurance go up when I add my 16-year-old?

For your family, the honest answer is: ask for a quote before it happens. The Triple-I recommends calling your insurance professional before your teen gets a learner's permit, so you know the cost in advance and can plan.

When you call, ask for the price under a few scenarios so you can see what moves the number:

  • Teen listed as an occasional driver of an existing family car vs. the primary driver of their own car
  • Your current deductibles vs. higher collision and comprehensive deductibles
  • With and without a good-student or driver-training discount
  • With and without a usage-based (telematics) program

The scenarios let you see the trade-offs instead of accepting a single total.

What drives the size of the increase

  • Your state. Rating rules differ, and some states limit factors insurers can use.
  • The teen's age and sex, where state law allows these factors. The Virginia Bureau of Insurance lists age, sex, driving record, vehicle and location among the factors insurers use.
  • The car. Expensive, fast or high-repair-cost vehicles cost more to insure.
  • Which car the teen is assigned to. The Triple-I says some insurers assign the most expensive driver, usually the teen, to the most expensive car to insure.
  • Your coverage. Higher limits and lower deductibles raise the premium; so does adding a vehicle.
  • The teen's record. A ticket or at-fault crash can raise the price at renewal.

Add your teen to your policy or buy them their own?

Usually, adding them to your policy costs less. The Triple-I says it's generally less expensive for parents to add teenagers to their policy than for teens to buy one on their own, and that insuring the teen's car with your insurer may qualify you for a multi-vehicle discount. Consumer Reports' analysis came to a similar conclusion.

Don't try to save money by leaving a licensed teen off the policy. The Triple-I says drivers who live with you and use your car should be listed. The Texas Department of Insurance warns that if an insurer learns about an undisclosed household driver, it may bill for the missed premium, deny claims or decline to renew. Consumer Reports adds that removing a young driver who still lives at home can have serious financial consequences.

Ways to lower the cost of insuring a teen driver

Ask for every teen and student discount

The Triple-I lists discounts insurers commonly offer for:

  • students who keep at least a "B" average;
  • teens who complete a recognized driver training course; and
  • college students who attend school at least 100 miles from home and don't bring a car.

Consumer Reports says good-student discounts, where offered, can be worth hundreds of dollars a year. It also cautions that driver-training discounts may be small, sometimes under $100 a year. Ask your insurer for the actual dollar amount of each discount.

Choose the car carefully

A safe, moderately priced car usually costs less to insure than a sports car or a new luxury model. The Virginia Bureau of Insurance advises against high-performance and sports cars for young drivers. Consumer Reports suggests sharing an existing family car if possible, since you won't add a vehicle to the policy and a family car often has more safety features. Get insurance quotes before you buy a car for your teen.

Assign the teen to the right car

Ask your insurer how it assigns drivers to vehicles. If it allows it, the Triple-I suggests assigning your teen to the least valuable car.

Consider higher deductibles, but keep strong liability

Raising collision and comprehensive deductibles lowers the premium. Only choose an amount you could actually pay after a claim. Our guide to $500 vs. $1,000 deductibles walks through the math.

Don't cut liability to save money. The Triple-I recommends increasing liability protection when you add a teen. Consumer Reports notes the Triple-I suggests at least $100,000/$300,000/$100,000. A serious crash can easily exceed state minimums, and you could be personally on the hook. See how much car insurance you need for help choosing limits.

Look at telematics, with open eyes

Usage-based programs track driving habits through an app or device. Consumer Reports found policyholders using their insurer's telematics device saved a median of $120 a year. It also notes there's no guarantee a young driver will save, and you give up some privacy. Ask whether the data can raise your rate as well as lower it.

Shop around

Insurers price young drivers very differently. Consumer Reports found that drivers who switched insurers in the past five years saw a median annual savings of $461. Get at least three quotes for identical coverage that includes your teen. Our hub guide on how to get cheaper car insurance explains how to compare quotes like for like.

Build safe habits early

The Triple-I suggests involving your teen in the insurance conversation and explaining how tickets and crashes raise costs. It also recommends graduated licensing rules, a parent-teen driving agreement and lots of supervised practice, and notes that some insurers offer a discount for completing a safe-driver program. A clean record is the best long-term discount: the Triple-I says rates will drop as teens get older, provided they keep a good driving record.

Checklist before your teen gets a permit

  • Called your insurer for quotes under several scenarios
  • Asked about good-student, driver-training and away-at-school discounts
  • Priced the specific car your teen will drive
  • Asked how the insurer assigns drivers to cars
  • Reviewed liability limits, and raised them if needed
  • Priced a higher collision and comprehensive deductible you can afford
  • Got at least three quotes for identical coverage

The bottom line

Adding a teen driver usually brings one of the biggest jumps a household policy will see, because teens carry the highest crash risk of any age group. You can't change that risk overnight, but you can control the car, the discounts, the deductibles and the insurer. Start the conversation before the permit, compare several quotes, keep liability strong, and let a clean record bring the price down over time.

Frequently asked questions

How much will my car insurance go up when I add my 16 year old?

There's no official average, and the increase depends on your insurer, state, cars, coverage and your teen's record. Expect a noticeable jump: the CDC says drivers ages 16 to 19 have a fatal crash rate almost three times that of drivers 20 and older per mile driven, and insurers price that risk. Ask your insurer for a quote before your teen gets a permit.

Do I have to add my teen driver to my car insurance?

Usually yes once they're licensed and living with you. The Triple-I says drivers who live with you and use your car should be listed. Rules for permit holders vary, so call your insurer when your teen gets a learner's permit. The Texas Department of Insurance warns that undisclosed household drivers can lead to back-billed premium, denied claims or non-renewal.

Is it cheaper for a teen to have their own policy?

Usually not. The Triple-I says it's generally less expensive to add a teen to a parent's policy than for the teen to buy one alone, and Consumer Reports reached a similar conclusion. Compare both quotes if you're unsure.

When does car insurance go down for a teen driver?

Rates generally fall as a young driver gains experience and keeps a clean record. The Triple-I says that as teenagers get older, rates will drop if they have a good driving record. How fast depends on the insurer and state.
