Calculable loss: There are two elements that must be at least estimable, if not formally calculable: the probability of loss, and the attendant cost. Probability of loss is generally an empirical exercise, while cost has more to do with the ability of a reasonable person in possession of a copy of the insurance policy and a proof of loss associated with a claim presented under that policy to make a reasonably definite and objective evaluation of the amount of the loss recoverable as a result of the claim.
Geico: Geico is the fourth-best car insurance company, and even a cave man can see why. Geico customers say it’s easy to file a claim with the company, though some were unhappy with status updates from the insurer. That said, most Geico customers would recommend it and plan to renew their policy. Their rates may have something to do with that: Geico offers lower rates on average than most other auto insurance companies.

Large loss: The size of the loss must be meaningful from the perspective of the insured. Insurance premiums need to cover both the expected cost of losses, plus the cost of issuing and administering the policy, adjusting losses, and supplying the capital needed to reasonably assure that the insurer will be able to pay claims. For small losses, these latter costs may be several times the size of the expected cost of losses. There is hardly any point in paying such costs unless the protection offered has real value to a buyer.

The best car insurance companies have a few things in common: They have straightforward shopping experiences, take good care of policyholders after a crash and treat their customers with respect and courtesy. That means only insurers with high customer satisfaction scores and relatively few complaints to insurance commissioners make it to the top of our list of the best auto insurance companies.
How much car insurance costs depends on the amount of risk you pose to your auto insurance company. Remember, if you have an incident and make a claim on your insurance policy, your insurance company must pay – even if you’ve only paid them $1,000 in premiums and you make a claim that costs $100,000. If it’s more likely that you’ll need to make a number of claims on your car insurance, you’ll get charged more. It’s just the insurance company making sure they don’t lose money on your policy.

Limited risk of catastrophically large losses: Insurable losses are ideally independent and non-catastrophic, meaning that the losses do not happen all at once and individual losses are not severe enough to bankrupt the insurer; insurers may prefer to limit their exposure to a loss from a single event to some small portion of their capital base. Capital constrains insurers' ability to sell earthquake insurance as well as wind insurance in hurricane zones. In the United States, flood risk is insured by the federal government. In commercial fire insurance, it is possible to find single properties whose total exposed value is well in excess of any individual insurer's capital constraint. Such properties are generally shared among several insurers, or are insured by a single insurer who syndicates the risk into the reinsurance market.

An entity which provides insurance is known as an insurer, insurance company, insurance carrier or underwriter. A person or entity who buys insurance is known as an insured or as a policyholder. The insurance transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate the insured in the event of a covered loss. The loss may or may not be financial, but it must be reducible to financial terms, and usually involves something in which the insured has an insurable interest established by ownership, possession, or pre-existing relationship.
