What Does Actuarial Mean?

“Actuarial” refers to anything related to actuaries or the use of data, statistics, and figures to assess risk and determine premium rates. It may be used to describe tables, reports, exams, charts, adjustments, and other related materials.

Insuranceopedia Explains Actuarial

Insurance companies often rely on actuaries, professionals who analyze data to evaluate risk, to calculate key statistics. Based on this actuarial information, they determine premium prices for their products. The output of this work is what consumers actually see when they shop for coverage. Two drivers with similar profiles can get very different quotes from different insurers because each company runs its own actuarial models, which is why it pays to compare car insurance rates rather than accepting the first number offered.

Calculating risk is essential to assess the likelihood of paying out claims. If risks are not accurately understood, the company may set premiums too low, potentially leading to financial losses. The same logic explains why a 30-year-old and a 50-year-old pay very different rates for the same coverage, and why the average cost of life insurance changes as mortality data gets updated. In short, actuarial information is critical to the success and stability of insurance companies.
