Actuary Responsibilities

Actuaries use statistics to calculate the economic impact of risks. By drawing on probability, statistics, and financial theory, actuaries calculate the likelihood of events. After analyzing financial information, actuaries create presentations and reports to help their clients account for risk.

Many actuaries work in the insurance industry. They help insurance companies create life insurance and health insurance policies. Actuaries also work in business and finance, recommending strategies to executives to minimize risk and increase profits. Finally, some actuaries work in the public sector, managing benefits plans like Social Security.

"As an actuary, I assess the financial consequences of risk and uncertainty," explains actuary Steven Walker. "I assess the risk of potential events using mathematics, statistics, and financial theory, and I assist businesses and clients in developing policies that reduce the cost of that risk. My work is critical to the insurance part of the company."

Day in the Life of an Actuary

Actuaries work for insurance companies, financial institutions, and consulting firms. Their daily tasks vary depending on their specialty.

Common daily tasks for an actuary include:

  • Analyzing financial data to recommend strategies
  • Creating reports and presenting data to clients or executives
  • Testing investment strategies to calculate risk
  • Calculating the probability of events that increase costs

In Walker's actuarial role, tasks include analyzing data and presenting his findings. "I value insurance policies and advise businesses on how to meet regulatory requirements and balance capital. I have a busy professional life and may review, prepare, and present reports to clients and executives whose financial well-being depends on the results of actuarial science daily."

Types of Actuaries

Life Insurance Actuary

Life insurance actuaries create life insurance policies that cover individuals and groups. They do so by examining demographic data and life expectancy tables. These actuaries account for factors like health, age, and risk behaviors to set premium rates for life insurance. They also calculate annuity policies.

Property and Casualty Actuary

Property and casualty actuaries create insurance policies related to property loss and liability. Their scope may cover policies related to natural disasters, automobile accidents, fires, and other types of accidents. These actuaries analyze the probability of property-damaging events or accidents that create liability to set insurance premiums.

Health Insurance Actuary

Health insurance actuaries estimate the likelihood that individuals or groups will need medical treatment to create health insurance policies. They also predict the cost of healthcare to determine what the policy will cover. These actuaries consider factors like age, family medical history, and occupation to create health insurance policies.

Enterprise Risk Actuary

Enterprise risk actuaries help corporations minimize the cost of risks such as economic volatility, regulation changes, or geopolitical unrest. They evaluate how these risks might impact the company to help executives make strategic decisions. These actuaries also recommend strategies to limit the financial harm of risks.

Savings and Retirement Actuary

Savings and retirement actuaries evaluate company benefits plans, including pensions and 401(k)s. They test benefits plans to make sure the company can cover costs. Pension actuaries must report their findings to the government. These actuaries may also offer retirement planning strategies for individual clients.

Public Sector Actuary

Public sector actuaries ensure that government benefits plans can cover recipients. For example, they may specialize in Social Security or Medicare, where they project the federal government's financial obligations or test proposed changes. Public sector actuaries may also regulate insurance company rates.

Investment Actuary

Investment actuaries specialize in the financial risk of investment strategies. They recommend risk management approaches to organizations. Some investment actuaries also manage investments. These actuaries research market volatility and propose strategies to minimize risk when investing.

How to Become an Actuary

Professionals must possess bachelor's degrees for entry-level actuary roles. While some major in actuarial science, prospective actuaries can also major in other fields.

"Getting into an actuarial career can begin with any bachelor's degree. Most actuaries major in mathematics, actuarial science, statistics, or another analytical field," says Walker. A bachelor's in business administration, finance, or economics can also lead to opportunities as an actuary.

After earning bachelor's degrees, actuaries pursue professional certification in their focus areas. The Casualty Actuarial Society (CAS) and the Society of Actuaries (SOA) certify actuaries, with CAS focusing on property and casualty specialties and SOA focusing on finance and insurance.

"Professional certification requires coursework in economics, statistics, and corporate finance," explains Walker. Candidates also pass 7-10 certification exams depending on the credential.

Certified actuaries must meet continuing education requirements to maintain an associate certification or earn fellowship certification. While completing the certification process, which can take several years, actuaries often gain work experience. They can also pursue a master's in actuarial science or a master's in finance to advance in their career.
