<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📐 &#039;&#039;&#039;Coverage unit&#039;&#039;&#039; is the standardized measure an [[Definition:Insurance carrier | insurer]] uses to quantify the amount of exposure a policy represents for [[Definition:Rating | rating]] and [[Definition:Premium | premium]] calculation purposes. Rather than treating every policy as a unique pricing exercise, insurers assign a unit of measurement that reflects the fundamental driver of loss potential for a given [[Definition:Line of business | line of business]]. In [[Definition:Workers&#039; compensation insurance | workers&#039; compensation]], the coverage unit is typically each $100 of [[Definition:Payroll | payroll]]; in [[Definition:Homeowners insurance | homeowners]] insurance, it is often each $1,000 of insured dwelling value; and in [[Definition:Commercial general liability (CGL) | general liability]], it might be revenue, square footage, or number of units sold.<br /> <br /> ⚙️ During the [[Definition:Underwriting | underwriting]] and [[Definition:Rating | rating]] process, the number of coverage units is multiplied by a [[Definition:Rate | rate]] — a price per unit — to arrive at the base [[Definition:Premium | premium]]. For example, if a workers&#039; compensation rate is $3.50 per $100 of payroll and a business reports $2 million in payroll, that equals 20,000 coverage units and a base premium of $70,000 before any [[Definition:Experience modification factor | experience modification]] or [[Definition:Schedule rating | schedule rating]] adjustments. [[Definition:Actuarial analysis | Actuaries]] select the appropriate unit to ensure it correlates closely with loss frequency and severity, so that the resulting premiums are proportional to actual risk.<br /> <br /> 📈 Choosing the right coverage unit matters because it directly affects the fairness and accuracy of the [[Definition:Insurance pricing | pricing]] model. A poorly chosen unit creates cross-subsidies — lower-risk policyholders effectively pay for higher-risk ones — which invites [[Definition:Adverse selection | adverse selection]] and erodes a carrier&#039;s [[Definition:Loss ratio (L/R) | loss ratio]] over time. Regulators review the units embedded in [[Definition:Rate filing | rate filings]] to confirm they are actuarially sound and not unfairly discriminatory. For [[Definition:Insurtech | insurtechs]] exploring usage-based or parametric models, redefining coverage units — say, shifting auto insurance from annual mileage tiers to per-mile pricing — can unlock new market segments and improve risk segmentation.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Rate]]<br /> * [[Definition:Exposure]]<br /> * [[Definition:Premium]]<br /> * [[Definition:Actuarial analysis]]<br /> * [[Definition:Experience modification factor]]<br /> * [[Definition:Rating]]<br /> {{Div col end}}</div>
