Adding a driver to car insurance costs between $100 and $3,000 per year, depending on the driver's age, driving record, and experience. Most insurers don't charge a fee for adding someone (there's no administrative cost) but your premium will adjust based on the new driver's risk profile.
- Teen drivers (16 to 19): Premiums jump $2,000 to $3,000 per year
- Young adults (20 to 25): Premiums rise $1,000 to $2,000 per year
- Experienced adults (26 to 60): Premiums climb $100 to $300 per year
- Experienced drivers with excellent records: May lower your rates
Full coverage averages $2,008 annually (MoneyGeek's 2024 analysis). Add a teen, and cost nearly doubles. Adding an experienced spouse causes a 5% bump or less.
