An actuary is a business professional who uses mathematics, statistics, and financial theory to measure and manage risk. Most actuaries work in the insurance industry, where they calculate the likelihood of events like car accidents, natural disasters, or early death, then help companies set prices and hold enough money in reserve to pay future claims. But actuaries also work in pension planning, healthcare, government, investment management, and corporate strategy, anywhere an organization needs to put a dollar figure on uncertainty.
What Actuaries Actually Do
The core of actuarial work is building mathematical models that predict financial outcomes. In an insurance company, that translates into two essential tasks: pricing and reserving. Pricing means calculating the premium you pay for a policy so the insurer collects enough to cover expected claims and still operate profitably. Reserving means estimating how much money the company needs to set aside today to pay claims that will come in later, including claims on events that have already happened but haven’t been reported yet.
Outside of insurance, actuaries take on a wider range of problems. Enterprise risk management actuaries help executives identify economic, financial, and geopolitical risks that could derail a company’s plans, then build strategies to limit the financial damage. Pension actuaries design and evaluate retirement plans, testing whether the funds set aside today will actually be enough to pay benefits decades from now. They’re required to report those evaluations to the federal government. In the public sector, actuaries at the federal level evaluate proposed changes to Social Security and Medicare, while state-level actuaries may regulate the rates insurance companies charge.
Some actuaries work in investment strategy, building models that balance risk and return for companies or individuals. Others consult for professional services firms, where they might advise clients across several industries in a single week.
Specialization Tracks
Actuaries typically specialize in one of a few major areas, each with its own professional focus and day-to-day challenges.
Property and casualty actuaries deal with risks to physical property and liability exposure. That includes homeowners insurance, auto insurance, workers’ compensation, commercial liability, and coverage for events like floods and earthquakes. Emerging risks like climate change, terrorism, and autonomous vehicles keep this field evolving, as actuaries continually update models that were built on historical patterns that may no longer apply.
Life insurance actuaries use mortality data, capital markets knowledge, and financial concepts like the time value of money to design contracts that protect families financially when someone dies. Modern life actuaries are also deeply involved in managing the investment of company assets to make sure the insurer stays solvent over the long term.
Health actuaries work in one of the fastest-changing corners of the profession. They help insurers and health plans design premium rates, estimate liabilities (including claims that have been incurred but not yet reported), and adjust future premiums based on claims experience. Government policy shifts, from changes in healthcare law to new regulations on drug pricing, directly affect their work.
Pension actuaries focus on retirement benefits, evaluating whether a company’s pension fund is on track, designing 401(k) plans, structuring retiree healthcare benefits, and sometimes advising individuals on retirement planning.
How to Become an Actuary
Most actuaries start with a bachelor’s degree in mathematics, statistics, actuarial science, or a related quantitative field. But the degree alone isn’t enough. The profession is built around a rigorous series of exams administered by two main credentialing organizations: the Society of Actuaries (SOA), which covers life, health, pension, and financial risk, and the Casualty Actuarial Society (CAS), which covers property and casualty.
The exam process is long. Through the CAS, for example, earning the Associate credential (ACAS) requires passing exams in probability, financial mathematics, modern actuarial statistics, basic ratemaking, regulation, and predictive analytics, along with completing coursework on professionalism and validation by educational experience (VEE) credits, which cover economics, accounting, and statistics topics typically completed in college. Reaching the Fellow level (FCAS) requires three additional exams covering advanced claims estimation, advanced ratemaking, and risk management.
Most aspiring actuaries begin taking exams while still in college and continue passing them over several years while working full-time. The full path from first exam to Fellow-level credential commonly takes seven to ten years. Employers generally expect you to keep progressing through exams and often cover study materials and exam fees, give paid study time, and provide salary increases for each exam you pass.
What Actuaries Earn
Actuarial compensation rises steeply with each exam passed and each year of experience. According to the Ezra Penland 2025-2026 actuarial salary surveys, which capture base pay plus bonus, an entry-level actuary with two exams and up to one year of experience typically earns $67,000 to $92,000, depending on specialty. Property and casualty entry-level pay skews slightly higher than health or pension roles at the same exam level.
The jump after earning an Associate credential is significant. An ACAS or ASA with five years of experience typically earns in the range of $120,000 to $195,000. Fellows with substantial experience earn considerably more. An FCAS with 20-plus years of experience can earn $248,000 to $655,000 in total compensation, and senior Fellows in life, health, or pension work see comparable ranges at the top end, often exceeding $500,000.
These wide ranges reflect the difference between actuaries in staff roles and those in leadership positions like chief actuary or chief risk officer. The profession consistently ranks among the highest-paying careers accessible with a bachelor’s degree.
Where Actuaries Work
Insurance companies remain the largest employer of actuaries, but the profession has expanded well beyond traditional insurance. Consulting firms hire actuaries to advise clients on everything from pension funding to enterprise risk. Corporate finance departments employ actuaries for internal risk assessment. Government agencies at both the federal and state levels need actuaries to evaluate public benefit programs and regulate insurance markets.
The Bureau of Labor Statistics groups non-insurance actuarial employers into professional and technical services firms, management companies, and government agencies. In practice, actuaries today show up in banks, tech companies, healthcare systems, and any large organization that needs to quantify financial uncertainty in a disciplined way.
Skills That Define the Role
Strong math ability is the obvious prerequisite, but actuarial work demands more than computation. You need to be comfortable with large datasets and statistical software, and increasingly with programming languages like Python, R, and SQL. Predictive analytics and machine learning are becoming standard tools, especially in property and casualty work where new data sources are transforming how risk is modeled.
Communication matters just as much. Actuaries regularly present complex findings to executives, regulators, and clients who don’t share their technical background. Translating a statistical model into a clear business recommendation is a core part of the job. The profession also carries ethical weight: actuaries sign off on the financial soundness of insurance products and pension plans, and their calculations directly affect how much consumers pay for coverage and whether retirees receive their promised benefits.
