Actuaries analyze the financial costs of risk and uncertainty. They use mathematics, statistics, and financial theory to assess the risk of potential events, and they help businesses and clients develop policies that minimize the cost of that risk. Actuaries’ work is essential to the insurance industry.

Actuaries typically do the following:

  • Compile statistical data and other information for further analysis
  • Estimate the probability and likely economic cost of an event such as death, sickness, an accident, or a natural disaster
  • Design, test, and administer insurance policies, investments, pension plans, and other business strategies to minimize risk and maximize profitability
  • Produce charts, tables, and reports that explain calculations and proposals
  • Explain their findings and proposals to company executives, government officials, shareholders, and clients

Actuaries in the insurance industry typically specialize in a specific field of insurance, such as one of the following:

Health insurance actuaries help develop long-term care and health insurance policies by predicting expected costs of providing care under the terms of an insurance contract. Their predictions are based on numerous factors, including family history, geographic location, and occupation.

Life insurance actuaries help develop annuity and life insurance policies for individuals and groups by estimating, on the basis of risk factors such as age, gender, and tobacco use, how long someone is expected to live.

Property and casualty insurance actuaries help develop insurance policies that insure policyholders against property loss and liability resulting from accidents, natural disasters, fires, and other events. They calculate the expected number of claims resulting from automobile accidents, which varies with the insured person’s age, sex, driving history, type of car, and other factors.

Some actuaries apply their expertise to financial matters outside of the insurance industry. For example, they develop investment strategies that manage risks and maximize returns for companies or individuals.

Pension and retirement benefits actuaries design, test, and evaluate company pension plans to determine if the expected funds available in the future will be enough to ensure payment of future benefits. They must report the results of their evaluations to the federal government. Pension actuaries also help businesses develop other types of retirement plans, such as 401(k)s and healthcare plans for retirees. In addition, they provide retirement planning advice to individuals.

Enterprise risk actuaries identify any risks, including economic, financial, and geopolitical risks that may affect a company’s short-term or long-term objectives. They help top executives determine how much risk the business is willing to take, and they develop strategies to respond to these issues.

Actuaries also work in the public sector. In the federal government, actuaries may evaluate proposed changes to Social Security or Medicare or conduct economic and demographic studies to project future benefit obligations. At the state level, actuaries may examine and regulate the rates charged by insurance companies.

Some actuaries are considered consultants and provide advice to clients on a contract basis. Many consulting actuaries audit the work of internal actuaries at insurance companies or handle actuarial duties for insurance companies that are not large enough to keep their own actuaries on staff.
