Answer in brief

Insurers disagree about 18-year-olds more than about almost any other group, so the spread for identical coverage is often $1,500 or more a year. Compare properly: fix the coverage set, keep inputs identical (licence date, VIN, address, mileage), mention every discount to every insurer, get four or more quotes, add fees, and ask how fast the inexperience factor steps down. Re-compare at 19, at three years licensed and at 21.
