Actuary

An actuary is a professional who specializes in analyzing financial risk and uncertainty, particularly in the fields of insurance, pensions, and investments. Actuaries use mathematics, statistics, and financial theory to calculate premiums, reserves, and probabilities of future events such as illness, disability, or death. Their work ensures that insurance plans remain financially stable and that companies can meet future claim obligations while staying competitively priced.

In health and dental insurance, actuaries determine the cost of coverage based on factors such as claim frequency, age demographics, inflation in healthcare costs, and plan design features like deductibles and maximums. They play a key role in setting renewal rates, designing sustainable benefit structures, and forecasting long-term financial performance for insurers and group plans.
Actuaries must balance fairness to policyholders with financial stability for the insurer, ensuring that premiums are sufficient to cover claims while remaining affordable for consumers.

Example:

‍

When a health insurer reviews claim data and finds that prescription drug costs have increased by 8 percent over the past year, an actuary adjusts the premium rates accordingly to maintain the plan’s sustainability.

What to Watch For:

Actuaries base their projections on assumptions that can change over time due to medical advances, economic shifts, or regulatory updates. Understanding their role helps explain why premiums may rise even if individual claim history remains low.
