Interested in a career as an actuary?
Wondering who determines how insurance companies price risk and plan for future claims?
Insurance actuary explained
When people think of insurance, they often picture brokers selling policies, adjusters handling claims, or underwriters evaluating applications. Behind the scenes, however, actuaries play a critical role in helping insurance companies measure and manage financial risk.
An insurance actuary is a professional who uses mathematics, statistics, economics, and data analysis to help insurers understand the financial impact of risk. Their analysis helps insurance companies estimate future claims costs, set premiums, determine how much money they need to pay future claims, and remain financially strong.
While underwriters evaluate individual insurance applications, actuaries analyze trends across thousands, or even millions, of policies. Their work supports pricing decisions, financial planning, product development, reinsurance, and long-term profitability.
What does an actuary do?
Actuaries help insurance companies answer questions such as:
- How much should we charge for a particular insurance product?
- How much are future claims likely to cost?
- How much money should we set aside today to pay claims in the future?
- How are inflation, severe weather, fraud, litigation, or emerging risks likely to affect future claims?
- How much reinsurance should we purchase to protect against catastrophic losses?
- Is a particular product or line of business profitable?
Their analysis supports many aspects of an insurer’s business, including:
- Pricing insurance products
- Establishing claims reserves
- Developing new insurance products
- Purchasing reinsurance
- Managing capital
- Enterprise risk management
- Financial forecasting
The goal is to ensure the insurance company remains financially strong while offering competitive products to customers.
How actuaries differ from underwriters
Although actuaries and underwriters both work with risk, they perform very different roles.
An actuary analyzes data across an insurer’s entire portfolio to develop pricing models, estimate future claims costs, and evaluate the profitability of different products and lines of business.
An underwriter applies those pricing models and underwriting guidelines when evaluating individual applicants, deciding whether to accept a particular risk and under what terms.
For example, an actuary may analyze historical claims data, inflation, and weather-related claim trends and project that commercial property claims will become more expensive in the future. Based on those projections, the actuary may recommend higher premiums for commercial property insurance.
An underwriter then applies the approved rates and underwriting guidelines when evaluating an individual property, taking into account its specific characteristics and exposures.

Why insurance actuaries matter
Insurance companies promise to pay future claims, but they must decide today how much to charge for coverage and how much money to set aside to meet those future obligations.
Actuaries provide the analysis that makes those decisions possible. Their work helps insurers price products fairly, maintain adequate claims reserves, purchase appropriate reinsurance, manage financial risk, and remain financially stable.
Although actuaries rarely interact directly with policyholders, their work influences nearly every aspect of the insurance business, from the premiums customers pay to the products insurers offer and the long-term financial strength of the companies that provide coverage.
