An Experience Table is a statistical tool used in actuarial science and insurance to adjust and refine assumptions in valuation mortality tables based on the actual experience of a specific insured population. This table records and analyzes the observed incidences such as mortality, morbidity, or lapse rates, tailoring predictions and adjustments to reflect true observed behaviors rather than generic or industry-wide assumptions.
Importance of Experience Tables
Adjusting Mortality Assumptions
Experience Tables are crucial for revising mortality assumptions, ensuring that the predictions align more closely with the observed experience of the insured cohort, leading to more accurate and fair premium calculations.
Actuarial Accuracy
By incorporating real-world data, actuaries can refine their models and forecasts, reducing the risk of mispricing insurance products and improving the financial stability of insurance companies.
Structure and Components
Data Collection
Collecting data for an Experience Table typically involves gathering detailed records of policyholders’ outcomes, such as death claims, policy lapses, and other pertinent events over a specific period.
Analysis and Adjustment
The collected data is then analyzed to determine the actual experience rates (e.g., mortality rates). These rates are compared against standard assumptions, and necessary adjustments are made to valuation tables used in actuarial models.
Key Applications
Life Insurance
Experience Tables are extensively used in life insurance to refine mortality assumptions. For example, a life insurance company may develop an Experience Table specifically for a certain age group or a type of policy.
Health Insurance
In health insurance, Experience Tables help adjust morbidity rates, better reflecting the actual incidence of diseases and medical conditions among policyholders.
Pension Plans
Pension plans use Experience Tables to adjust the assumed life expectancy of plan members, thereby maintaining the accuracy of pension cost estimates and funding requirements.
Historical Context
The use of Experience Tables dates back several centuries, rooted in the early development of actuarial science. The first mortality tables, which were essential precursors, emerged in the 17th century, but it was not until the 19th and 20th centuries that insurers began systematically collecting and analyzing their own data.
Comparisons to Related Terms
Valuation Mortality Table
A Valuation Mortality Table provides industry-standard mortality rates for use in valuing life insurance contracts. Experience Tables adjust these standard tables to reflect actual observed data specific to an insurer’s own portfolio.
Actuarial Life Table
An Actuarial Life Table, or mortality table, shows the probability of death at each age. An Experience Table refines these probabilities based on a more specific dataset.

Summary
An Experience Table is a crucial actuarial tool that adjusts the assumptions in valuation mortality tables based on the actual experience of a specific insured population. By ensuring that the predictions align more closely with observed behaviors, these tables play a critical role in pricing, risk management, and financial stability within the insurance industry. Updated regularly and used extensively in life, health, and pension insurance, Experience Tables help actuaries create more accurate models and forecasts.
