Why Insurance Rates Vary by State
Two drivers with identical cars, ages, and clean records can pay wildly different premiums — sometimes a $1,000-a-year difference — purely because of which state they live in. The same is true for homeowners, life, business, and pretty much every other line. State-level pricing differences come down to four big drivers:
- State law and minimum coverage requirements. Some states require more coverage than others. Michigan's no-fault PIP rules and Florida's uninsured-motorist exposure drive auto premiums up; New Hampshire's optional-coverage rules drive them down.
- Risk concentration. Hurricane Alley, Tornado Alley, the wildfire belt, and earthquake zones all push homeowners and landlord premiums higher. Hail-prone states (Texas, Oklahoma, Colorado) lead the country in roof claims.
- Claim frequency and severity. Urban density, fraud rates, repair costs, and litigation patterns are all priced into your rate. Louisiana and Michigan consistently rank among the most expensive states for car insurance for these reasons.
- Regulatory environment. Some state insurance commissioners cap rate increases more aggressively than others, which can keep premiums in check (California) or constrain carrier participation (which lifts prices over time).

How We Source State Rate Data
Rate figures on each state hub come from a mix of public NAIC filings, state insurance department reports, and rates pulled live from our partner carriers when consumers run quotes through our comparison tools. We refresh state-level averages quarterly and re-rank cheapest-carrier lists when partner pricing changes.
Insurance is regulated state by state, so the cheapest carrier in Texas often isn't the cheapest in Vermont. Our hubs make that comparison explicit — what's the cheapest for your state, not the national average.
Frequently Asked Questions
Which state has the cheapest insurance overall?
It depends on the line. For car insurance, Maine, Idaho, Vermont, and New Hampshire are consistently among the cheapest. For homeowners, Hawaii, Vermont, and Delaware rank low for premiums (though Hawaii's hurricane and lava-flow exposure is excluded from baseline policies). For business insurance, low-population, low-litigation states like North Dakota and Wyoming run cheaper than coastal urban states.
Which state has the most expensive insurance?
Florida and Louisiana lead the country for both car and homeowners — Florida because of hurricane risk and litigation; Louisiana because of fraud, uninsured-motorist rates, and Gulf exposure. Michigan tops the car-insurance charts because of its unique PIP rules. New York and California lead for business insurance because of litigation environment and high property values.
How often do rates change?
Carriers refile rates with each state's insurance commissioner roughly annually. Major catastrophic events (hurricane seasons, wildfire seasons, large-scale court rulings) can trigger mid-year rate revisions. Our state hubs are refreshed quarterly and after any major rate-filing news.
If I move, will my rate change?
Almost always, yes. Even moving across town can change your auto premium (different territory code); moving to a different state almost guarantees a recalculation. Get a quote before you move so the cost is part of your relocation decision.
Does Simply Insurance sell policies?
We're a licensed independent broker — we don't underwrite policies ourselves. We compare quotes from A-rated carriers across every state and territory we operate in, and we may receive compensation from carriers when you purchase a policy through our links. This doesn't change the rates you're quoted.
