What Is Actuarial Science?
Actuarial science is a specialized field that evaluates financial risks within the insurance and finance sectors, utilizing advanced mathematical and statistical techniques. By applying probability analysis and statistics, actuarial science aims to define, analyze, and address the financial ramifications of uncertain future events. Traditionally, actuarial science mainly focuses on studying mortality rates, constructing life tables, and utilizing compound interest.

Understanding Actuarial Science
Actuarial science aims to quantify the likelihood of events occurring through probability analysis to evaluate their financial impact. Primarily utilized in the insurance industry by actuaries, this discipline involves analyzing mathematical models to predict the likelihood of events, enabling insurance companies to set aside funds for potential claims. For instance, studying mortality rates for specific age groups helps insurers understand when life insurance payouts may occur.
Originating as a formal mathematical discipline in the late 17th century to meet the increasing demand for long-term insurance, actuarial science encompasses various interconnected subjects, including mathematics, probability theory, statistics, finance, economics, and computer science. Over the past three decades, advancements in high-speed computing and the integration of stochastic actuarial models with modern financial theory have transformed the field significantly.
Applications of Actuarial Science
Actuarial science plays a critical role in life insurance and pension plans, analyzing liabilities and enhancing financial decision-making within financial organizations. Actuaries leverage their expertise to evaluate the financial and economic implications of future events across various business applications.
Insurance
In life insurance, actuarial science focuses on mortality analysis, life table creation, and the utilization of compound interest to develop financial products like annuities, which offer a fixed income stream. Actuarial science also assesses the financial outcomes of investable assets held by non-profit entities due to endowments.
Health insurance involves analyzing disability, morbidity, mortality rates, and fertility to evaluate risk factors. For example, disability rates for veterans wounded in service help determine disability insurance payouts based on assigned disability percentages. Actuarial science extends to property, casualty, liability, and general insurance policies offered on renewable terms.
Pensions
Within the pension sector, actuarial science compares alternative strategies regarding pension plan design, funding, accounting, and management. Pension plans involve contributions from employers to provide retirement benefits to employees. Bond rates significantly influence pension plans and their investment decisions, with economic conditions and market trends impacting plan viability.
Factors such as benefit arrangements, collective bargaining, employer competition, and workforce demographics also affect pension plan sustainability. Tax regulations, IRS policies on pension surplus calculations, and market fluctuations further influence the financial health of pension plans. Actuaries may also engage in public sector initiatives related to Social Security and healthcare programs.
Universities and Professional Certifications
The Bureau of Labor Statistics projects a 23% growth in actuary employment from 2022 to 2032, resulting in an increased demand for educational programs and professional certifications in actuarial science. Various universities offer degrees and courses in actuarial science, along with professional designations to enhance credibility in the field.
Universities
Recognizing academic excellence, the Society of Actuaries designates colleges with three levels of recognition based on professional exam requirements. Center of Actuarial Excellence schools, with specific criteria, are acknowledged for their exceptional competency. As of December 2022, several universities across different countries hold this prestigious accolade.
Noteworthy universities in the U.S. with Center of Actuarial Excellence status include Brigham Young, Georgia State, Purdue, Connecticut, and Michigan.
Actuaries’ median annual wage in 2021 was $113,990, according to the latest BLS data.
Professional Designations and Credentials
Actuaries can pursue various professional designations to demonstrate expertise and competence in the field. The Casualty Actuarial Society offers Associate (ACAS) and Fellow (FCAS) membership levels requiring different numbers of exams to achieve. The Society of Actuaries conducts exams covering fundamental risk management and financial decision-making concepts.
Certifications such as Associate of the Society of Actuaries (ASA) and Fellow (FSA) signify proficiency in risk modeling, financial decisions, and knowledge application across different areas. Chartered Enterprise Risk Analyst (CERA) credentials specialize in risk identification and management within enterprises.
Is Actuarial Science Difficult?
Actuarial science is a challenging profession, with rigorous exams lasting hours and extensive preparation requirements. Candidates typically pursue a bachelor’s degree and may spend a decade completing the necessary training and exams.
What Type of Math Do Actuaries Use?
Actuaries rely on probability, statistics, and financial mathematics to assess the likelihood of events and their financial implications. While calculus may be a prerequisite for certain courses, actuaries primarily focus on probability and statistical analyses in their work.
How Long Does It Take To Become an Actuary?
It typically takes several years, up to a decade or more, to become an actuary. Completing a bachelor’s degree in actuarial science may take 3 to 5 years, with additional years required to pass professional exams.
The Bottom Line
Actuarial science involves mathematically predicting future events’ probabilities and assigning them monetary values. Actuaries play a crucial role in helping companies, pension funds, and insurers navigate risks by developing models and strategies to address potential challenges proactively.
