How do insurance companies generally determine premiums?

Insurance companies determine premiums primarily by analyzing risk factors associated with the applicant. This process involves evaluating various factors, such as the individual's age, health status, medical history, and sometimes lifestyle choices. Each of these elements helps insurers assess the likelihood of a policyholder needing medical care and the potential costs that could arise from this care.

For instance, younger individuals typically have lower health risks, while older individuals may have higher premiums due to an increased likelihood of health issues. Similarly, a person's health status and medical history, such as any chronic conditions or past surgeries, are critical in determining how much risk the insurer takes on. This tailored approach allows insurers to set premiums that accurately reflect the level of risk they are assuming and ensures that those who present a higher risk contribute more towards the costs associated with their care.

In contrast, determining premiums based solely on income does not provide a comprehensive view of the risk involved. Customer surveys about satisfaction with health services are not related to risk assessment for premium calculation. Offering a flat rate for all applicants disregards individual differences in health and risk, which is not practical for a system designed to balance costs across a diverse group of policyholders.
