No two drivers pay the same price for what looks like the same policy. Insurers price each driver individually, weighing dozens of factors against each other, so your neighbor with a similar car and a similar age can end up paying noticeably more or less than you. Rates also vary a lot by state and by insurer, which is exactly why it's worth comparing quotes rather than assuming a single "average" figure applies to you — see our state-by-state guides for current minimum-coverage requirements and typical premiums where you live.
Age is one of the biggest factors insurers use, mostly because it's a proxy for experience. Teenagers and other new drivers are statistically far more likely to be in an accident than an experienced driver in their thirties or forties, so insurers charge accordingly — often close to double what an established driver pays for the same coverage. Rates typically ease once a driver reaches their mid-twenties and stay relatively stable through middle age, then can tick back up somewhat for older drivers as reaction times slow.
A teenager can usually be covered two ways: added to a parent's existing policy, or insured on a separate policy of their own. Adding a teen to a family policy is almost always cheaper than a standalone policy, since a standalone policy has to price the teen's inexperience with no offsetting history from other household drivers.
In states that allow it, insurers have historically charged men somewhat more than women for the same coverage, based on broad accident-rate statistics — young men in particular are overrepresented in serious crash data. That gap narrows or disappears as drivers get older. It's also not universal: several states, including Massachusetts, prohibit insurers from using gender as a rating factor at all, so this doesn't apply everywhere.
Your own history carries more weight than almost anything else you can influence. Moving violations, at-fault accidents, and prior claims all signal risk to an underwriter, and serious or repeated violations can raise your rate substantially. A clean multi-year record is one of the most reliable ways to keep your premium down — see our guide on how a claim or accident affects your rate for what to expect after an incident.
What you drive matters almost as much as how you drive. Insurers price in the cost to repair or replace your specific vehicle, how expensive its parts are, how likely it is to be stolen, and even its horsepower and safety record. An older, common sedan is reliably cheaper to insure than a new sports car or luxury vehicle.
In most states, insurers are allowed to factor in a credit-based insurance score, which studies have linked (imperfectly) to claims likelihood. A handful of states restrict or ban this practice, so whether it affects you depends on where you live.
