How do insurance companies use AI to determine premiums

Learning From Patterns in Historical Risk Data

Insurance companies use AI to determine premiums primarily by analyzing large volumes of historical claims and risk data, identifying patterns that connect specific risk factors to the likelihood and cost of future claims, and then applying these learned patterns to price individual policies more precisely than relying solely on broader traditional actuarial categories.

Why Historical Data Is the Foundation

AI-based pricing models are generally trained on extensive historical data connecting policyholder characteristics and circumstances to actual claims outcomes, allowing the model to learn statistical relationships between specific risk factors and the probability and cost of future claims — relationships that might not be immediately obvious or easily captured using simpler, traditional actuarial approaches.

Why AI Can Incorporate a Wider Range of Data

Compared to traditional actuarial models, AI-based approaches can potentially incorporate a broader and more granular range of data variables simultaneously, identifying more nuanced combinations of factors associated with risk than simpler models relying on a more limited set of predetermined categories.

Why This Enables More Individualized Pricing

By identifying more precise patterns connecting specific risk factors to actual outcomes, AI-based models can support more granular risk segmentation, potentially resulting in premiums that more precisely reflect an individual applicant’s specific risk profile rather than relying on broader, less precise traditional risk categories that might group together policyholders with genuinely different underlying risk levels.

Why Regulatory Oversight Constrains This Process

Despite this technical capability, insurance pricing remains subject to significant regulatory oversight, generally requiring that any pricing factor used be actuarially justified — meaning it must have a demonstrated, legitimate connection to actual risk — and not constitute illegal discrimination based on protected characteristics, meaning insurers can’t simply use any available data point without regard to these established regulatory constraints.

Why This Remains an Actively Evolving Area of Insurance Practice

Given the rapid growth of available data and AI modeling techniques, alongside genuine regulatory and public concern about fairness and discrimination in insurance pricing, how AI is used to determine premiums continues to evolve, with ongoing regulatory attention aimed at ensuring these increasingly sophisticated models remain fair and appropriately justified.

Bottom Line

Insurance companies use AI to determine premiums by analyzing historical claims and risk data to identify patterns connecting risk factors to future claim likelihood and cost, enabling more individualized pricing based on a specific applicant’s risk profile — a process that remains subject to regulatory requirements that pricing factors be actuarially justified and non-discriminatory.
