<p><b>New page</b></p><div>📐 '''Pure premium''' represents the portion of an [[Definition:Insurance | insurance]] [[Definition:Premium | premium]] that corresponds solely to the expected cost of [[Definition:Claims | claims]] — excluding all [[Definition:Expense loading | expense loadings]], [[Definition:Profit margin | profit margins]], [[Definition:Commission | commissions]], and other operational costs. In [[Definition:Actuarial analysis | actuarial]] terms, it is the product of expected [[Definition:Loss frequency | loss frequency]] and expected [[Definition:Loss severity | loss severity]] for a given risk or class of risks, often expressed on a per-unit-of-exposure basis (per policy, per $1,000 of insured value, or per payroll dollar, depending on the line of business). It serves as the foundational building block of [[Definition:Ratemaking | ratemaking]] — every final rate charged to a [[Definition:Policyholder | policyholder]] begins with the pure premium before layers of expense and contingency are added.<br />
<br />
🧮 Calculating the pure premium requires [[Definition:Actuary | actuaries]] to analyze historical [[Definition:Loss experience | loss experience]], adjust it for [[Definition:Loss development | loss development]] (since claims may not be fully settled for years), apply [[Definition:Trend factor | trend factors]] to account for inflation and changing loss patterns, and normalize the data to a current cost level. For lines like [[Definition:Workers' compensation insurance | workers' compensation]] or [[Definition:Personal automobile insurance | personal auto]], advisory organizations such as the [[Definition:National Council on Compensation Insurance (NCCI) | NCCI]] or the [[Definition:Insurance Services Office (ISO) | ISO]] publish prospective pure premium estimates — sometimes called "loss costs" — that individual carriers can adopt and then apply their own [[Definition:Expense loading | expense loads]] and [[Definition:Underwriting | underwriting]] modifications to produce final rates. This approach decouples the actuarial estimation of expected losses from each carrier's unique cost structure and competitive positioning, promoting both pricing accuracy and regulatory transparency.<br />
<br />
📊 Understanding the pure premium is critical for evaluating an insurer's underwriting performance and pricing adequacy. The [[Definition:Loss ratio | loss ratio]] — actual losses divided by earned premiums — is ultimately a comparison of realized claims costs against the total rate, but dissecting it into the pure premium component versus expense and profit elements reveals where performance is breaking down. If an insurer's actual pure premium consistently exceeds the assumed level, it signals either deteriorating risk selection, inadequate [[Definition:Rating | rate levels]], or adverse external trends. Conversely, favorable pure premium experience may indicate a competitive advantage in risk selection or [[Definition:Loss control | loss control]]. For [[Definition:Reinsurer | reinsurers]] pricing treaties and for [[Definition:Insurtech | insurtech]] companies building new products, anchoring the analysis in a rigorously derived pure premium is the surest path to sustainable pricing.<br />
