Where you live can swing your car insurance bill by more than a thousand dollars a year, even with the exact same driving record and vehicle. Rural, lower-density states consistently top the list of cheapest places to insure a car — Vermont, Maine, New Hampshire, Ohio, and Idaho are regularly among the least expensive nationwide, with full coverage often running well below the national average. These states tend to share a few things in common: less traffic congestion, fewer severe weather claims, lower rates of uninsured drivers, and less litigation around accident claims, all of which keep the cost of paying out claims lower for insurers — and that savings gets passed on in the form of cheaper premiums. On the opposite end, states like Nevada, Louisiana, Florida, and Michigan tend to rank among the most expensive, often due to a combination of dense traffic, higher accident rates, and, in some cases, state laws that make claims more costly to settle.
National averages and state rankings are a useful starting point, but they don’t reflect what you’ll actually pay, since your own premium still depends on your driving record, the vehicle you drive, and the coverage level you choose — sometimes more than location does. To see a number specific to your situation rather than a state average, our car insurance calculator factors in these personal details alongside your location. It’s also worth understanding the broader pricing factors insurers use before comparing quotes, covered in how car insurance premiums are calculated, and how much your own driving history can move the number regardless of which state you’re in, explained in how your driving record affects insurance costs. If you’re also deciding between coverage levels, our comparison of full coverage vs. liability insurance shows how much that choice affects your final premium on top of where you live.
