Running an insurance business means constantly making decisions about things nobody can predict with certainty. How many claims will come in next year? How long will policyholders live? How much capital does the business need to stay solvent through a bad year? That's where actuarial services come in.
At their core, actuarial services exist to turn uncertainty into something a business can actually plan around. Actuaries pull together historical data, statistical models, and financial theory to answer the questions that keep insurance executives up at night — and to make sure the answers hold up under regulatory scrutiny.
If you've ever wondered how an insurer decides what to charge for a policy, how much money it needs to set aside for future claims, or how it proves to regulators that it's financially sound, you're really asking about actuarial services. These services touch nearly every financial decision an insurer makes, from actuarial pricing and claims reserving to actuarial valuation, risk management, and compliance with standards like IFRS 17.
This guide walks through what actuarial services are, what actuaries actually do day to day, and how these services support insurance companies across life, general, and pension lines. By the end, you'll understand how actuarial valuation, pricing, reserving, modeling, and compliance all fit together — and what to look for when choosing an actuarial services provider.
What Are Actuarial Services?
A Simple Definition of Actuarial Services
Actuarial services are professional services that apply mathematics, statistics, and financial theory to data in order to measure and manage financial uncertainty. In insurance, this typically means using historical and financial data to support insurance pricing, reserving, valuation, and broader risk management decisions.
Put simply, actuaries take messy, uncertain real-world data — how many people file claims, how long policyholders live, how markets behave — and turn it into numbers a business can rely on.
What Do Actuarial Services Include?
Actuarial services cover a wide range of technical and advisory work, including:
- Actuarial valuation of insurance and pension liabilities
- Insurance pricing and premium calculation
- Claims reserving, including IBNR estimates
- Risk management, including stress testing and scenario analysis
- Capital modeling and solvency assessment
- Actuarial modeling for pricing, valuation, and projections
- IFRS 17 measurement and reporting support
- Actuarial data analytics, including predictive modeling
- Regulatory reporting and compliance documentation
- Pensions and employee benefits valuation and funding analysis
Each of these areas works together — you can read a full breakdown in What Are Actuarial Services? A Complete Guide for Insurance Businesses.
What Does an Actuary Do?
Key Responsibilities of an Actuary
An actuary's job blends analysis, judgment, and communication. Day to day, an actuary will typically:
- Analyze financial and insurance data
- Assess risk across different products and portfolios
- Develop actuarial assumptions (mortality, lapse, expense, and more)
- Calculate liabilities and reserves
- Support insurance pricing decisions
- Estimate future claims
- Build and maintain actuarial models
- Conduct scenario and sensitivity analysis
- Support regulatory and compliance requirements
- Translate technical findings into financial insights for leadership
What Does an Actuary Do for an Insurance Company?
The actuarial process generally follows a clear path:
An actuary starts with raw data, layers on assumptions grounded in experience and statistics, runs that through an actuarial model, analyzes the resulting risk, and delivers a recommendation that shapes a real business decision — whether that's a premium rate, a reserve balance, or a capital requirement. For a deeper look at this role, see What Does an Actuary Do? Roles, Responsibilities & Business Applications.
Why Do Insurance Companies Need Actuarial Services?
Why are actuarial services important for insurance companies? Insurance companies need actuarial services because their entire business model depends on accurately pricing and reserving for future events that haven't happened yet. Without actuarial expertise, insurers risk underpricing products, under-reserving for claims, and failing to meet capital and solvency requirements.
Insurers face several recurring challenges that actuarial services are built to solve:
- Uncertainty around future claims
- Pricing risk across different products and customer segments
- Accurately estimating insurance liabilities
- Meeting capital requirements and solvency standards
- Producing reliable financial forecasts
- Satisfying regulatory compliance obligations
- Evaluating whether a product is genuinely profitable
- Managing risk exposure across the portfolio
Get any one of these wrong, and the consequences show up quickly — in financial statements, in regulatory findings, or in a product that quietly loses money for years before anyone notices.
Types of Actuarial Services
Life Insurance Actuarial Services
Life insurance actuarial services focus on the long-term, mortality-driven nature of life products. This includes:
- Life insurance pricing
- Mortality assumptions
- Longevity risk analysis
- Reserving for long-duration liabilities
- Valuation of policy liabilities
- Experience studies to refine assumptions over time
- Product profitability analysis

Pension actuarial services help organizations manage long-term obligations to employees, including pension valuation, funding analysis, defined benefit plans, employee benefit obligations, and long-term financial liabilities. See Pension Actuarial Services: Valuation, Funding & Risk Management for more detail.
IFRS 17 Actuarial Services
IFRS 17 actuarial services support insurers through one of the most significant accounting changes the industry has seen. This includes IFRS 17 measurement, actuarial assumptions, insurance liabilities, the contractual service margin (CSM), risk adjustment, the premium allocation approach (PAA), the general measurement model (GMM), the variable fee approach (VFA), actuarial models, parallel runs, and reporting.

Actuarial Valuation Explained
What Is Actuarial Valuation?
Actuarial valuation is the process of estimating the current financial value of future insurance or pension liabilities using data, assumptions, and mathematical models.
Why Is Actuarial Valuation Important?
Actuarial valuation underpins insurance liabilities, pension obligations, financial reporting accuracy, risk assessment, and capital planning. Without a reliable valuation, an insurer can't know whether it holds enough assets to meet its future obligations.
What Is Included in an Actuarial Valuation?
A typical actuarial valuation includes:
- Underlying data
- Actuarial assumptions
- Actuarial models
- Discount rates
- Projected future cash flows
- Resulting liabilities
- Sensitivity analysis
Read the full process in Actuarial Valuation Explained: Methods, Process & Applications.
Insurance Claims Reserving
What is insurance claims reserving? Insurance claims reserving is the process of estimating the money an insurer needs to set aside to pay claims that have already occurred but haven't been fully paid or reported yet.
Reserving includes several components: case reserves for known claims, IBNR for claims not yet reported, ultimate claims estimates, claims development patterns, and ongoing reserve adequacy testing.
What is IBNR in insurance? IBNR, or "incurred but not reported," refers to claims that have already occurred but haven't yet been reported to the insurer. Actuaries estimate IBNR using historical claims development patterns so that reserves reflect the true, ultimate cost of claims — not just the ones already filed.

Actuarial Pricing
Actuarial pricing is how insurers translate risk into a dollar figure a customer actually pays.
How Do Actuaries Calculate Insurance Premiums?
Premiums are built from several components, including expected claims frequency and severity, operating expenses, a risk margin, target profitability, historical experience data, and predictive models that refine expected outcomes.
Risk-Based Insurance Pricing
Risk-based insurance pricing means premiums reflect the underlying risk of the policyholder or portfolio — higher-risk customers pay more, and lower-risk customers pay less, keeping pricing both fair and sustainable. Choose a granular, data-driven pricing approach if your portfolio has wide variation in risk profiles; a broader pricing structure may suffice for more homogeneous books. Learn more in Actuarial Pricing: How Insurance Companies Calculate Premiums.
Actuarial Risk Management
Types of Risks Actuaries Analyze
Actuaries evaluate a wide spectrum of risk, including insurance risk, mortality risk, longevity risk, market risk, credit risk, catastrophe risk, model risk, and operational risk.
How Actuaries Help Insurers Manage Risk
Actuaries quantify these risks, build them into pricing and reserving assumptions, and recommend risk mitigation strategies — from reinsurance to product design changes.
Stress Testing and Scenario Analysis
Stress testing and scenario analysis examine how an insurer's financial position would hold up under adverse conditions, such as a spike in claims or a market downturn. These exercises are core to ORSA and broader capital adequacy assessments. Read more in Actuarial Risk Management: How Insurers Measure & Manage Risk and Insurance Stress Testing & Scenario Analysis: An Actuarial Guide.
Actuarial Modeling
What Is Actuarial Modeling?
Actuarial modeling follows a defined process:
Common Actuarial Models
Common model types include pricing models, reserving models, valuation models, risk models, capital models, projection models, and IFRS 17 models.
Actuarial Model Validation and Governance
Actuarial model validation confirms that a model produces accurate, reliable results, while actuarial model governance ensures models are documented, reviewed, and controlled appropriately over time.
Actuarial Modeling Tools
Actuaries commonly rely on tools such as Prophet, ResQ, and Python for statistical modeling and predictive analytics. Learn more in Actuarial Modeling in Insurance: Methods, Tools & Best Practices.

Types of Data Used by Actuaries
Actuaries work with policy data, claims data, customer data, financial data, historical experience data, and market data.
Predictive Analytics and Machine Learning in Actuarial Work
Predictive analytics and machine learning are increasingly used to refine pricing accuracy, detect emerging claims trends, and improve reserve estimates. Learn more in Predictive Analytics in Insurance: An Actuarial Perspective and Machine Learning in Actuarial Science: Applications & Use Cases.
Actuarial Services for Regulatory Compliance
How do actuarial services support regulatory compliance?
