An actuary is a professional who uses mathematics and statistics to study uncertain future events, especially related to insurance and pensions. Actuaries quantify risk, price insurance products, calculate the reserves insurers must hold, and advise on financial solvency — making them the mathematical backbone of the insurance industry.
The word “actuary” comes from the Latin actuarius, meaning a keeper of accounts or records. Today, a U.S. actuary is a highly trained professional who holds one of the most consistently top-ranked careers in America. The Bureau of Labor Statistics (BLS) projects 23% employment growth for actuaries through 2032 — far faster than the national average — driven by increasing complexity in insurance, healthcare, pension, and enterprise risk management.
In the United States, actuaries are credentialed primarily through the Society of Actuaries (SOA) for life, health, and pension work, and the Casualty Actuarial Society (CAS) for property and casualty insurance. All actuaries practicing before U.S. regulators must also hold the MAAA (Member of the American Academy of Actuaries) designation. This article provides a complete guide to what actuaries do, how they are credentialed, and their critical role in the U.S. insurance system.

✅ MAAA is Mandatory for Regulatory Work: Any actuary signing an Actuarial Opinion, preparing a rate filing memorandum for regulator reliance, or providing actuarial advice to government bodies in the U.S. must hold the MAAA designation. The MAAA confirms the actuary is subject to the Code of Professional Conduct and ASB Actuarial Standards of Practice (ASOPs). An FSA or FCAS without MAAA cannot sign regulatory opinions.
The Appointed Actuary (AA) is one of the most significant regulatory roles in U.S. insurance. Every life and health insurance company domiciled in the U.S. must designate an Appointed Actuary who:
- Is qualified: holds FSA (or FCAS for certain lines) + MAAA
- Meets Qualification Standards for Actuaries Issuing Statements of Actuarial Opinion (AAA Qualification Standards)
- Is designated formally by the insurer’s Board of Directors
- Signs the Actuarial Opinion and Actuarial Opinion Summary in the insurer’s NAIC Annual Statement each year
🧾 What the Appointed Actuary Certifies (NAIC Annual Statement)
| Reserve Adequacy | Statutory reserves are computed in accordance with the NAIC Valuation Manual and applicable state law |
| Assumption Appropriateness | Actuarial assumptions (mortality, interest, lapse, morbidity) are reasonable in the aggregate |
| Method Compliance | Reserve calculation methods comply with the Standard Valuation Law (SVL) and applicable ASOPs |
| VM-20 / VM-22 / VM-25 | For PBR business: deterministic and stochastic reserve requirements have been tested and satisfied |
| Opinion Type | Clean, Qualified, Adverse, or Disclaimer — the AA must explain any qualification or adverse opinion |
🚨 Legal Liability of the Appointed Actuary: An Appointed Actuary who signs a false or materially misleading Actuarial Opinion can face professional discipline (ABCD review), loss of credentials, civil liability, and in extreme cases criminal prosecution for insurance fraud. The role carries substantial personal legal responsibility, which is why the AA designation and MAAA credential are non-negotiable requirements.

Actuaries consistently rank in top 10 of “Best Jobs in America” surveys. Demand driven by complex healthcare reform, climate risk, cyber insurance, and pension obligations.
Salary by Practice Area (2024–2026 Estimates)
All credentialed U.S. actuaries are bound by the Code of Professional Conduct, adopted by all major U.S. actuarial organizations (SOA, CAS, AAA, CCA, and others). Key precepts include:
| Precept | Requirement |
|---|---|
| Precept 1 — Competence | Actuaries shall perform services only when they are competent to do so, or will ensure competent review |
| Precept 2 — Credentials | Actuaries shall not misrepresent qualifications; credentials must be accurately disclosed |
| Precept 3 — Standards of Practice | Actuaries shall comply with ASOPs (Actuarial Standards of Practice) issued by the ASB |
| Precept 4 — Communications | Actuarial communications must be clear, accurate, complete, and objective |
| Precept 5 — Disclosure | Actuaries must disclose material limitations, assumptions, and potential conflicts of interest |
| Precept 6 — Conflicts of Interest | Actuaries shall act with independence and objectivity; disclose any conflicts; decline work if conflict cannot be managed |
| Precept 7 — Courtesy and Cooperation | Actuaries shall cooperate with ABCD inquiries; treat colleagues and clients professionally |
| Precept 13 — Public Interest | Actuaries must consider the public interest, not just the interests of the employer or client who hired them |
⚠️ Discipline: The Actuarial Board for Counseling and Discipline (ABCD) handles complaints against U.S. actuaries. Violations of the Code can result in reprimand, suspension, or expulsion from actuarial organizations — effectively ending an actuary’s career. The ABCD’s decisions are published (with anonymization in many cases) in actuarial publications.

An actuary is a professional who uses mathematics, statistics, and financial theory to study uncertain future events — primarily in insurance and pensions. Actuaries assess financial risk, set insurance premium rates, calculate the reserves insurers must hold, evaluate solvency, and advise on pension plan funding. In the U.S., they hold credentials such as FSA, FCAS, or EA, and MAAA.
Actuaries in insurance companies: (1) price insurance products by calculating premiums; (2) calculate reserves for future claims; (3) assess capital adequacy and solvency under NAIC RBC standards; (4) design new insurance products; (5) analyze mortality, morbidity, and loss experience; (6) advise on reinsurance; and (7) as Appointed Actuary, certify reserve adequacy in the Annual Statement filed with state insurance regulators.
To become a U.S. actuary: earn a bachelor’s degree in math or actuarial science; pass Exam P and FM (preliminary); get actuarial analyst work experience; complete VEE credits; continue passing SOA or CAS fellowship exams; earn ASA or ACAS (Associate, 3–5 years); then FSA or FCAS (Fellow, 7–10 years total). Add MAAA membership (required for regulatory work). Most employers pay for study materials and exam fees.
BLS median annual wage for U.S. actuaries is approximately $120,000–$130,000. Entry-level analysts earn $60,000–$80,000. Fellows (FSA/FCAS) typically earn $140,000–$200,000+. Senior actuaries earn $180,000–$260,000+. Chief Actuaries at major insurance companies earn $300,000–$600,000+. Consulting actuaries often earn at the higher end of the scale. Location, practice area, and fellowship track significantly affect salary.
Actuaries set aggregate premium rates using mathematical models; underwriters apply those rates to individual applicants and make accept/decline decisions. Actuaries work at the portfolio level with statistical methods; underwriters work at the individual risk level using guidelines and judgment. Actuaries typically hold FSA/FCAS designations (7–10 years); underwriters typically hold CPCU designations (1–3 years). Both roles are essential to insurance operations but are distinct in function and training.
The Appointed Actuary (AA) is a qualified actuary (FSA or FCAS + MAAA) designated by an insurance company’s Board of Directors to certify the company’s reserves in the NAIC Annual Statement. The AA signs the Actuarial Opinion — a legal certification that the insurer’s reserves are adequate and computed in accordance with applicable law and actuarial standards. This is a regulatory requirement under NAIC model regulations for all U.S. life and health insurers.
