Car Insurance: What Actually Determines Your Rate

Average premium: $1,700/year ($142/month) for full coverage. But rates vary wildly. 25-year-old male with DUI in Michigan: $8,000/year. 45-year-old female, clean record in Maine: $800/year. Five factors dominate: age (under 25 = expensive), location (urban = 2x rural), driving record (1 ticket = +20%, DUI = +80%), vehicle (sports car = more), and credit score (poor credit = +50-100%).

Three coverage levels: Liability only (state minimum, $50-80/month), Standard full coverage (liability + comprehensive + collision, $120-150/month), Premium full coverage (high limits + extras, $180-250/month). Most people overpay by not shopping around—same coverage varies 40-60% between insurers.

When to Drop Coverage

Consider Dropping Collision/Comprehensive If:

  • Car value under $3,000-4,000
  • Annual premium exceeds 10% of car's value
  • You have emergency fund to replace car
  • Example: $2,000 car, $800/year collision = not worth it

NEVER Drop:

  • Liability coverage (legally required + protects assets)
  • Uninsured motorist (1 in 8 drivers has no insurance)
  • Don't go bare minimum—one accident can cost $100K+
