What Does an Actuary Do?

An actuary helps an organization understand the financial consequences of uncertain future events. Actuaries use data and mathematical models to estimate risks such as insurance claims or pension obligations. They test how estimates change when assumptions about the future change. Their analysis helps decision-makers evaluate pricing, reserves, funding, and other financial choices. By explaining the assumptions and uncertainty behind their results, actuaries help organizations plan without treating projections as guarantees.

What Is a Actuary?

An actuary analyzes risk and uncertainty that can affect an organization’s finances. The work is especially common in insurance, where projections help companies assess expected claims and set aside funds to pay them. Actuaries also work on pensions, healthcare costs, and broader financial risk. They do not make every business decision themselves; they provide analysis that leaders and other responsible professionals can use.

What Are the Main Responsibilities of a Actuary?

A central responsibility is estimating future costs from past and current data. For an insurer, an actuary may study how often claims occur and how much they cost. The method and assumptions depend on the type of risk being analyzed. The actuary checks whether the data is complete and comparable before relying on it.

Actuaries build or update models to turn the evidence into estimates. They test how results shift under different assumptions, such as changes in claim costs or settlement patterns. When a small change produces a large difference in the projection, that sensitivity is important to explain. Models help make uncertainty visible; they do not remove it.

In insurance, actuaries may estimate future claim costs to inform product pricing and reserves. Reserving concerns claims that have already occurred, including claims that are not yet reported or whose final cost remains uncertain. In pension work, actuaries estimate the resources needed to support future benefit payments. In each case, they document their approach and communicate how the results should be interpreted.

What Does a Actuary Do on a Daily Basis?

A typical project begins with a specific question, such as whether recent claims experience supports an existing pricing estimate. The actuary identifies the data needed and checks it for gaps or changes in how information was recorded. Next, they select a method and assumptions suited to the question, then use analytical software to develop or update a projection.

After reviewing the model’s results, the actuary tests how sensitive they are to important assumptions. They then prepare an explanation of the estimate, its limitations, and any material changes from earlier results. Colleagues and decision-makers review the analysis and consider it alongside other business factors. As new experience becomes available, the actuary may compare it with the projection and reassess the assumptions.

What Skills Does a Actuary Need?

Mathematical and statistical reasoning helps actuaries identify patterns and estimate possible outcomes. For example, when projected claim costs rise, an actuary needs to determine whether the change reflects a meaningful trend or a temporary shift in the data. Careful analytical judgment also helps them notice when a model’s output does not fit the evidence.

Computer skills support work with data and models. Actuaries use software to analyze information and test how assumptions affect results. Communication matters just as much: an actuary must explain why a projection changed and what uncertainty remains so that colleagues can use the analysis appropriately.

How Much Does a Actuary Earn?

The U.S. Bureau of Labor Statistics reports that actuaries had a median annual wage of $130,000 in May 2025. This is a national occupation-wide median, not a guaranteed salary; individual pay can vary by factors such as employer, experience, and location.

What Is the Career Progression for a Actuary?

Actuaries typically enter the occupation with a bachelor’s degree. Early-career workers often take professional exams while gaining experience, and may begin with analytical work that is reviewed by more experienced colleagues. The relevant exam pathway depends on the area of actuarial practice.

As actuaries gain experience and progress through professional requirements, they may take on more complex analyses and greater responsibility for reviewing work or leading projects. Some move into management or broader risk leadership. Requirements vary by role and jurisdiction; certain statutory pension valuations have a separate federal enrollment requirement, which does not apply to every actuarial job.

How Contingent Workforce Management Helps Businesses Hire Actuaries

Contingent workforce management services help companies engage and administer temporary workers for defined projects. An insurer facing a reporting deadline may need short-term actuarial modeling support for a reserve review, while keeping responsibility for conclusions with its internal actuarial leaders. When the company has already selected the worker, hiring that worker directly and using third-party payrolling can be a lower-cost alternative to a staffing agency.

TCWGlobal helps companies manage contingent actuaries through payrolling and workforce support. For a time-limited reserve review or model validation, payrolling can handle employment administration and pay processing while the company directs the technical work. This approach can save money compared with staffing-agency sourcing when the worker has already been found, and it reduces administrative work for the company’s team.
