In determining premiums and premium rate structures, insurers consider quantifiable factors, including location, credit scores, gender, occupation, marital status, and education level. However, the use of such factors is often considered to be unfair or unlawfully discriminatory, and the reaction against this practice has in some instances led to political disputes about the ways in which insurers determine premiums and regulatory intervention to limit the factors used.

Each insurance company evaluates personal factors in its own way, and they keep their methods as hidden as possible. So we can’t tell you which company puts high value in your occupation or emphasizes a clean driving history more than others. But to help you get going, we can show you a car insurance rate comparison for the same hypothetical driver and car, using average rates from across the country.


Property insurance provides protection against risks to property, such as fire, theft or weather damage. This may include specialized forms of insurance such as fire insurance, flood insurance, earthquake insurance, home insurance, inland marine insurance or boiler insurance. The term property insurance may, like casualty insurance, be used as a broad category of various subtypes of insurance, some of which are listed below:


Certain insurance products and practices have been described as rent-seeking by critics.[citation needed] That is, some insurance products or practices are useful primarily because of legal benefits, such as reducing taxes, as opposed to providing protection against risks of adverse events. Under United States tax law, for example, most owners of variable annuities and variable life insurance can invest their premium payments in the stock market and defer or eliminate paying any taxes on their investments until withdrawals are made. Sometimes this tax deferral is the only reason people use these products.[citation needed] Another example is the legal infrastructure which allows life insurance to be held in an irrevocable trust which is used to pay an estate tax while the proceeds themselves are immune from the estate tax.
When it comes to rate-saving opportunities, Allstate is in a league all by itself. Featuring an industry-leading stable of discounts, Allstate makes it easy to get a good deal on your coverage. For example, if you bundle your home and auto policies with Allstate, you can save up to 25%. If you haven’t filed a recent claim, you can save up to 20% with Allstate.
Allstate is more reasonable in terms of pricing, and it came out cheapest for drivers under age 25 in our quotes. Consumer Reports readers rated it just a hair lower than State Farm in overall satisfaction, but Allstate pulled ahead in J.D. Power ratings with a superior score in agent interaction. There’s no denying that Allstate is popular in Texas, with the second-most market share of any company at roughly 11.7%. It’s also one of the only companies to offer “gap” insurance for new cars, something that State Farm is missing. And if your Allstate quote is lower than those from its competitors, it could mean the difference in whether you can afford comprehensive and/or UM/UIM coverage, two especially valuable add-ons in Texas.

Insurance companies earn investment profits on "float". Float, or available reserve, is the amount of money on hand at any given moment that an insurer has collected in insurance premiums but has not paid out in claims. Insurers start investing insurance premiums as soon as they are collected and continue to earn interest or other income on them until claims are paid out. The Association of British Insurers (gathering 400 insurance companies and 94% of UK insurance services) has almost 20% of the investments in the London Stock Exchange.[26] In 2007, U.S. industry profits from float totaled $58 billion. In a 2009 letter to investors, Warren Buffett wrote, "we were paid $2.8 billion to hold our float in 2008."[27]

Plans vary greatly. But the general rule of thumb is that the less you pay per month, the higher your deductible is. Higher premiums are usually associated with lower deductibles. Generally it is beneficial for those with existing health issues to opt to pay more per month and less out-of-pocket for services. Those in good health often opt for a high deductible option in hopes that they never have to actually pay the deductible but would mostly be covered if something major happened. 


Any risk that can be quantified can potentially be insured. Specific kinds of risk that may give rise to claims are known as perils. An insurance policy will set out in detail which perils are covered by the policy and which are not. Below are non-exhaustive lists of the many different types of insurance that exist. A single policy that may cover risks in one or more of the categories set out below. For example, vehicle insurance would typically cover both the property risk (theft or damage to the vehicle) and the liability risk (legal claims arising from an accident). A home insurance policy in the United States typically includes coverage for damage to the home and the owner's belongings, certain legal claims against the owner, and even a small amount of coverage for medical expenses of guests who are injured on the owner's property.
Naturally, the float method is difficult to carry out in an economically depressed period. Bear markets do cause insurers to shift away from investments and to toughen up their underwriting standards, so a poor economy generally means high insurance premiums. This tendency to swing between profitable and unprofitable periods over time is commonly known as the underwriting, or insurance, cycle.[29]
The best companies will also have several supplemental coverage options, or endorsements, that you can add to your homeowners policy. Endorsements can vary, as some provide higher coverage limits for certain types of personal property like jewelry or fine furs; or they can provide supplemental coverage for risks — like water backups, floods, or earthquakes — not covered by home insurance.
An insurance underwriter's job is to evaluate a given risk as to the likelihood that a loss will occur. Any factor that causes a greater likelihood of loss should theoretically be charged a higher rate. This basic principle of insurance must be followed if insurance companies are to remain solvent.[citation needed] Thus, "discrimination" against (i.e., negative differential treatment of) potential insureds in the risk evaluation and premium-setting process is a necessary by-product of the fundamentals of insurance underwriting.[citation needed] For instance, insurers charge older people significantly higher premiums than they charge younger people for term life insurance. Older people are thus treated differently from younger people (i.e., a distinction is made, discrimination occurs). The rationale for the differential treatment goes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk of loss (the insured's death) is greater in any given period of time and therefore the risk premium must be higher to cover the greater risk.[citation needed] However, treating insureds differently when there is no actuarially sound reason for doing so is unlawful discrimination.

Adjusting liability insurance claims is particularly difficult because there is a third party involved, the plaintiff, who is under no contractual obligation to cooperate with the insurer and may in fact regard the insurer as a deep pocket. The adjuster must obtain legal counsel for the insured (either inside "house" counsel or outside "panel" counsel), monitor litigation that may take years to complete, and appear in person or over the telephone with settlement authority at a mandatory settlement conference when requested by the judge.
