The national average car insurance cost is $167 per month or $2,004 per year for full coverage in 2026. Minimum liability-only coverage averages $54 per month or $648 per year. Your actual rate depends on your age, driving record, credit score, location, vehicle, and coverage level.

The cheapest states are Vermont at $73 per month, Maine at $77 per month, and Idaho at $86 per month.

A 16-year-old driver averages $450 per month, a 25-year-old averages $140 per month, a 35-year-old averages $125 per month, a 45-year-old averages $120 per month, a 55-year-old averages $108 per month, a 65-year-old averages $130 per month, and a 75-year-old averages $180 per month.

What Determines Your Monthly Car Insurance Premium
Your rate is primarily determined by age, driving record, credit score (in 43 states), location, vehicle make and model, annual mileage, coverage level, and deductible. The difference between the highest and lowest risk driver profiles for the same vehicle in the same state can be $3,000+ per year. The difference between the cheapest and most expensive insurer for the same driver can be $1,000–$2,000 per year.
How to Reduce Your Monthly Car Insurance Payment
Increase your deductible from $500 to $1,000 to save 15–20 percent immediately. Bundle auto with home or renters insurance to save 10–25 percent. Shop quotes from at least 4 insurers annually since rates change and loyalty rarely saves money. Improve your credit score over 12–18 months for long-term savings. Enroll in a telematics program if you are a safe driver to save 10–30 percent based on actual driving behavior.
