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 (16-19): Premium increases by $2,000 to $3,000 per year
- Young adults (20-25): Premium increases by $1,000 to $2,000 per year
- Experienced adults (26-60): Premium increases by only $100 to $300 per year
- Experienced drivers with excellent records: May actually lower your rates
- For context, the national average annual premium for full coverage is $2,008, according to MoneyGeek's 2024 analysis. Adding a teen driver nearly doubles this cost, while adding an experienced spouse might increase it by less than 5%.
