Cheapest Widely Available Companies

  • Travelers: Frequently ranks as the cheapest national provider for full-coverage policies, averaging about $109 to $138 per month.
  • Erie Insurance: Offers some of the lowest average rates for minimum coverage (around $23/month), though it operates in a limited number of states.
  • State Farm: Known for competitive baseline rates and wide availability across all 50 states.

Key Factors Impacting Cost

  • Coverage Type: Minimum liability coverage is the cheapest option, while full coverage (which includes collision and comprehensive) costs more.
  • Personal Profile: Rates change based on your age, driving record, credit history, and ZIP code.

On average, GEICO is cheaper than AAA for auto insurance.

Cost Comparison
