How Insurers Think About Risk
Insurance is fundamentally a business of probabilities. An insurer collects premiums from a large pool of customers and uses that money to pay out claims. To stay solvent, they need to charge enough to cover expected losses — which means they spend considerable effort estimating how likely each policyholder is to file a claim and how costly that claim might be.
This process is called underwriting, and it's what produces your premium. The factors underwriters examine fall into a few broad categories: who you are, where you live, what you're insuring, and how you've behaved as a policyholder in the past. For a deeper look at how this process shapes your options, see our guide to risk profiles and underwriting.

Rating factors a typical auto insurer may consider
Industry underwriting literature consistently notes that modern auto insurers use dozens of variables, ranging from vehicle type to telematics data, to price individual policies.
3 states
States that ban credit scoring in auto insurance
California, Hawaii, and Massachusetts prohibit the use of credit-based insurance scores in auto insurance pricing, according to the National Conference of State Legislatures.
Personal and Demographic Factors
Many rating factors are tied directly to the individual policyholder. These vary by insurance type but commonly include:
- Age: Younger drivers and older adults often face higher auto and health premiums because statistical claim rates are higher in those groups.
- Health status and medical history: For health and life insurance, pre-existing conditions, tobacco use, and body mass index may be considered, subject to state and federal rules.
- Occupation: Some jobs expose people to higher physical risk, which can affect life, disability, or health premiums.
- Gender: Some states permit gender as a rating factor in auto insurance; others prohibit it.
It's worth knowing that state regulators must approve the factors an insurer is allowed to use. What's permitted in Texas may not be allowed in California.
Review Your CLUE Report Before Renewing
Consumers are entitled to a free copy of their CLUE (Comprehensive Loss Underwriting Exchange) report once per year. Reviewing it before your policy renews lets you spot errors that might be inflating your premium. Errors can be disputed with the reporting agency.
Location, Property, and What You're Insuring
Where you live and what you're covering play a major role in pricing. For homeowners insurance, insurers look at your home's age, construction type, proximity to a fire station, and local weather risk — hurricane-prone coastal areas carry higher premiums than inland regions. For auto insurance, your ZIP code reflects local accident rates, vehicle theft statistics, and even litigation trends.
The specifics of your policy also matter:
- Coverage limits: Higher limits mean more potential payout for the insurer, which increases your premium.
- Deductible amount: Choosing a higher deductible generally lowers your premium because you're absorbing more risk yourself.
- Add-ons and riders: Optional coverages — like roadside assistance or scheduled personal property — add to the base cost.
Understanding how these choices interact is essential. Our article on premiums, deductibles, and out-of-pocket maximums explains how the numbers fit together.
Behavioral and Financial History
Your past behavior as a consumer and policyholder is one of the strongest signals insurers use.
- Claims history: Filing multiple claims — even small ones — signals higher future risk. Some insurers track this through a shared database called CLUE (Comprehensive Loss Underwriting Exchange).
- Driving record: For auto policies, accidents and traffic violations directly raise your premium. A clean record is one of the most reliable ways to keep auto costs down.
- Credit-based insurance score: In states where it's permitted, insurers use a version of your credit data to predict claim likelihood. This is not the same as your FICO score, but it draws from similar data points.
Credit Scoring Rules Vary by State
While credit-based insurance scores are widely used in the U.S., their use is restricted or banned in certain states for specific insurance lines. If you're concerned about how your credit data is being used, contact your state's department of insurance for the rules that apply in your area.
Keep in mind that your premium reflects more than just your personal record. Broad trends — rising repair costs, increased natural disasters, or higher medical expenses — affect what everyone pays. For context on the full picture of what you're paying, see why your premium doesn't tell the whole cost story.

Frequently Asked Questions
Premiums can rise due to factors outside your control, such as increased claims activity in your area, inflation in repair or medical costs, or changes in the insurer's overall rate structure. Your individual record is only one part of the pricing equation.
Yes, in some cases. Bundling policies, raising your deductible, improving your credit score, or qualifying for discounts (such as safe driver programs or home security systems) can reduce your premium without reducing core coverage. Always confirm what you're giving up before making changes.
No. While common factors like age, location, and claims history are widely used, each insurer weighs them differently using its own proprietary models. State regulators must approve the rating factors insurers use, so some factors permitted in one state may be restricted in another.
In most states, yes. Insurers use a credit-based insurance score — different from your standard credit score — as a predictive tool. A few states, including California, Hawaii, and Massachusetts, restrict or prohibit its use in certain lines of insurance.
Underwriting is the process insurers use to evaluate your risk and decide whether — and at what price — to offer you coverage. Your premium is largely the financial output of that underwriting assessment.
