About Actuaries

Actuaries use mathematics, statistics, and financial theory to measure and manage risk in insurance, pension plans, and other financial systems. They analyze the likelihood of future events—accidents, illness, natural disasters, death—and quantify their financial consequences to help organizations set prices, maintain reserves, and design products that are financially sustainable. In property and casualty insurance, actuaries price auto, homeowners, and commercial policies by analyzing claims data and modeling loss frequency and severity. In life insurance and retirement planning, they develop mortality tables, price life and annuity products, and perform pension valuations. Health actuaries model medical costs and design benefit structures for health insurance plans. Actuaries are also increasingly employed in enterprise risk management, financial services regulation, and data science. The actuarial credential is earned through a rigorous series of professional examinations administered by the Society of Actuaries (SOA) or Casualty Actuarial Society (CAS), a process that takes five to ten years to complete while working full-time. Actuaries are among the most technically sophisticated professionals in financial services.
