Why it costs more
Insurers price inexperience. A driver with a short history gives the insurer little evidence of safe driving, and crash data for young drivers is worse than for experienced drivers. Age alone is not the whole story — record, car, mileage, and state all matter — but age and experience are strong rating factors, and they explain why a teen added to a family policy, or buying alone, faces a higher quote than an experienced driver with the same car and cover.
Cost also varies by structure. A teen on a parent's policy usually costs less overall than a teen buying a standalone policy, because the family policy spreads risk and may carry multi-car or multi-policy discounts. But the family policy's price still rises when the teen is added, and the rise depends on the car assigned to the teen, the cover chosen, and the state. No figure is stated here, because those inputs change the result completely.
Ways families lower it
Start with the car. Assigning a teen to the family's safest, modest, lower-value car, rather than the newest or most powerful car, usually produces a lower quote for that driver, because repair and crash risk follow the car. Next, review cover honestly: full coverage on a low-value car the family could replace may not be worth its quote cost, while liability limits should not be cut to the bone just to offset the teen's addition — a serious crash can exceed low limits quickly.
Then ask about discounts and programmes in general terms: good-student discounts where offered, driver-education completion, telematics or safe-driving programmes, and multi-policy bundling. Ask what each discount requires, how it is verified, and whether it survives a ticket or a claim. Finally, set driving rules at home — no phone use, no extra passengers early on, night-driving limits where the family agrees them — not only for safety, but because a clean record is the fastest route to lower prices as the driver gains experience.
