Insurance pricing is a delicate balance. Price too high, and you lose customers. Price too low, and your portfolio becomes unsustainable.
Sitting at the heart of this balance are actuarial pricing models and pricing methods – powerful tools that allow insurers to set premiums that are competitive, data-driven, and financially sound.
In this comprehensive guide, we’ll explain what actuarial pricing models are, how they work, the different methods actuaries use, and the latest innovations shaping the future of insurance pricing.
Whether you’re an actuary, underwriter, product manager or insurance leader, you’ll leave with a practical understanding of how pricing decisions are made – and why getting them right is critical.
What you will learn:
What Is Actuarial Pricing?
Actuarial pricing is the process of determining the right price for an insurance product using statistical models, historical data, and risk analysis techniques. The goal is to find a premium that:
- Covers expected claims and expenses
- Maintains the insurer’s solvency and profitability
- Remains competitive in the market
At its core, actuarial pricing bridges two priorities: customer value and business sustainability. It’s not just about setting prices – it’s about understanding risk exposure, predicting future claims, and ensuring the long-term health of the insurer’s portfolio.
For example, a motor insurer needs to calculate the likelihood of claims based on factors like age, driving history, location and vehicle type. Actuarial models process this data, estimate expected losses and translate them into fair, accurate premiums. Without robust pricing, insurers risk financial instability and market share erosion.

The Role of Actuarial Pricing Models
Actuarial pricing models are predictive tools that use data to estimate claims costs and determine appropriate premiums. These models assess the relationship between different risk factors and their impact on the likelihood, frequency and severity of claims.
By using structured, data-driven models, insurers can:
- Predict claims accurately – helping avoid underpricing or overpricing
- Segment customers based on risk profiles
- Optimise portfolio performance by balancing sales, retention and profit
- Stay compliant with regulatory standards requiring fair and transparent pricing
Think of actuarial pricing models as a decision engine. They analyse historical claims, customer behaviour and market conditions to generate a technical price – the price needed to cover expected claims and operating costs before strategic adjustments.

Types of Actuarial Pricing Models
Actuarial pricing has evolved significantly. While Generalised Linear Models (GLMs) remain the industry standard, modern insurers increasingly adopt machine learning, Bayesian inference and hybrid frameworks to stay competitive.
Here are the key types of pricing models you need to know:
Generalised Linear Models (GLMs)
GLMs are the most widely used actuarial models. They model claim frequency and claim severity separately, then combine the results to estimate total expected costs.
Why actuaries use them:
- Flexible and transparent structure
- Widely accepted by regulators
- Allow clear interpretation of risk drivers
Example:
A GLM might show that young drivers increase claims frequency by 20%, while owning a high-performance vehicle raises claim severity by 40%. Combining these insights helps set accurate premiums.
Machine Learning Models
With the explosion of data availability, insurers now use machine learning (ML) to capture complex patterns beyond traditional GLMs.
Advantages:
- Handle vast datasets efficiently
- Detect non-linear relationships between variables
- Improve risk segmentation and predictive accuracy
Example:
Machine learning (ML) algorithms like ‘random forests’ or gradient boosting can process millions of policyholder profiles, uncovering subtle risk signals that human analysts might miss.
Bayesian Models
Bayesian models help actuaries quantify uncertainty in pricing decisions. They are especially valuable for portfolios with limited data or volatile claims patterns.
Use case:
When launching a new insurance product, historical data may be scarce. Bayesian techniques allow actuaries to combine small datasets with prior knowledge to produce more stable pricing estimates.
Hybrid Models
Many insurers now integrate GLMs, machine learning and business rules into hybrid frameworks. These offer the interpretability of GLMs while benefiting from AI-driven insights, giving insurers the best of both worlds.
Scenario-Based & Catastrophe Models
For natural disasters, cyber risk and other extreme events, insurers use catastrophe models to simulate losses. These models integrate weather patterns, seismic activity and exposure data to stress-test portfolios against worst-case scenarios.
Actuarial Pricing Methods: How Premiums Are Set
Beyond the models, actuaries use structured pricing methods to determine the right premium. The process follows several steps:
Step 1: Data Collection and Cleaning
High-quality data is critical. Actuaries gather historical claims, customer demographics, exposure information and market data. The data validation step ensures accuracy and consistency.
Step 2: Frequency and Severity Modelling
Models estimate:
- Frequency: How often claims occur
- Severity: How costly those claims are
Combining these provides the expected loss cost.
Step 3: Calculating the Technical Price
The technical price includes expected claims costs, expenses and reinsurance costs. At this stage, the model ignores business strategy as it is a purely data-driven calculation.
Step 4: Applying Business Loadings and Adjustments
After the technical price is calculated, business considerations come into play:
- Distribution channel costs
- Profit margins
- Competitive positioning
- Regulatory constraints
This produces the target price.
Step 5: Optimisation to the Street Price
The street price is the final, customer-facing premium. Actuaries adjust pricing strategies to balance conversion rates, retention, and profitability, making sure the insurer remains competitive without compromising solvency.
Pricing Optimisation: Staying Competitive
Pricing optimisation is where actuarial science meets business strategy. Even when a technical price is accurate, insurers must adjust for market dynamics and customer behaviour.
Key techniques include:
- Using competitor price benchmarks
- Testing renewal retention sensitivity
- Running “what-if” simulations on conversion probabilities
- Segmenting strategies by channel, product, or risk profile
Done well, optimisation allows insurers to maximise profitability without losing customers or underpricing risk.
Common Challenges in Actuarial Pricing
Even with sophisticated models, pricing comes with pitfalls. Common challenges include:
- Poor data quality leading to distorted outputs
- Over-reliance on historical data without accounting for emerging risks
- Regulatory restrictions limiting pricing flexibility
- Overfitted models that perform well on past data but fail in the real world
- Siloed teams between actuarial, underwriting, and commercial units
MatBlas frequently supports insurers by reviewing models, validating frameworks, and delivering training to improve cross-functional collaboration.

FAQs
What is an actuarial pricing model?
An actuarial pricing model is a statistical tool used to predict future claims and set premiums accurately. It analyses historical data, identifies risk factors, and calculates expected losses.
What’s the difference between GLMs and machine learning in pricing?
GLMs are interpretable and widely accepted by regulators, while machine learning captures complex patterns and improves predictive accuracy. Many insurers use a hybrid approach.
Why is accurate pricing so important?
Incorrect pricing risks profitability, regulatory non-compliance, and customer trust. Accurate pricing creates sustainable portfolios and supports long-term growth.
How is the technical price different from the street price?
The technical price covers claims and expenses based purely on data. The street price is the customer-facing premium after strategic adjustments for competitiveness.
