The day your teenager gets a license, your car insurance bill changes more than it will at any other point in your life. MoneyGeek’s 2026 analysis put full coverage for a 16-year-old on a family plan at about $664 a month. An 18-year-old on the same kind of plan averaged $582. Those are additions most families feel.
What adding a teen costs, by age
Rates fall every year a teen drives without a claim, and the early drops are steep. MoneyGeek’s family-plan figures for full coverage:
- Age 16: about $664 a month ($7,962 a year)
- Age 17: about $621 a month ($7,452 a year)
- Age 18: about $582 a month ($6,988 a year)
- Age 19: about $522 a month ($6,262 a year)
Minimum coverage costs far less. WalletHub’s 2026 teen data put average minimum-coverage premiums at $3,192 a year for a 16-year-old and $1,623 a year for a 19-year-old. The catch is that minimum limits leave a young driver, and your household assets, exposed after a serious crash.
Family plan or their own policy?
Almost always the family plan. A teen on a parent’s policy borrows the household’s longer insurance history, multi-car discounts, and bundling credits. A standalone policy for a 16-year-old prices the teen as a brand-new driver with no history at all, and it usually costs hundreds more per month for the same coverage. Our teen driver guide walks through the parent-side decisions in detail.
Why boys cost more at 16
MoneyGeek’s age and gender table put a 16-year-old boy at $478 a month against $436 for a girl on its benchmark, a $504 yearly gap. By age 25 the gap shrinks to a few dollars a month. Several states, including California, Hawaii, Massachusetts, and Pennsylvania, restrict or ban gender in pricing, so the difference never appears there at all.
Ways to cut the added cost
Good student discounts are the biggest lever for most families, and they typically require a B average or better. A teen driver course helps at some carriers. The car matters too: putting your teen on the oldest, cheapest-to-repair vehicle in the household, and listing them as its primary driver honestly, keeps the surcharge attached to the lowest-value car.
Ask about distant-student rules if your teen heads to college without a car. Many insurers cut the rate sharply when the driver is away at school and only drives on breaks. Our timeline for when rates drop for young drivers shows how long the expensive years last, and the cost-by-age breakdown shows where your household lands next.
One warning worth repeating
Do not leave a licensed teen off your policy to save money. Insurers expect every licensed household member to be listed or formally excluded. A claim filed for an unlisted teen driver is exactly the kind of claim that gets denied, and the premium you saved will look small next to an uncovered accident bill.
