<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📘 &#039;&#039;&#039;Rating manual&#039;&#039;&#039; is a comprehensive reference document — or increasingly a digital rules engine — that contains the [[Definition:Rate | rates]], classification codes, rating algorithms, and modification factors an [[Definition:Insurance carrier | insurance carrier]] uses to calculate [[Definition:Premium | premiums]] for a specific [[Definition:Line of business | line of business]]. It translates the output of an insurer&#039;s [[Definition:Pricing model | pricing model]] into a structured set of instructions that [[Definition:Underwriter | underwriters]], [[Definition:Insurance agent | agents]], and quoting systems follow when generating a price for a given [[Definition:Risk | risk]]. Bureau organizations like the [[Definition:Insurance Services Office (ISO) | Insurance Services Office]] and the [[Definition:National Council on Compensation Insurance (NCCI) | National Council on Compensation Insurance]] publish widely adopted manuals that individual carriers may use as filed, or modify with their own proprietary adjustments.<br /> <br /> 📑 A typical manual includes base rates organized by [[Definition:Class of business | classification]], territory factors that reflect geographic loss differences, [[Definition:Experience rating | experience-rating]] formulas that reward or penalize accounts based on [[Definition:Claims history | claims history]], and schedules of [[Definition:Endorsement | endorsement]] charges for optional coverages. It also specifies minimum premiums, [[Definition:Deductible | deductible]] credits, and rules for calculating [[Definition:Composite rate | composite rates]] when multiple exposures are combined on a single [[Definition:Insurance policy | policy]]. Each element links back to [[Definition:Actuarial | actuarial]] analysis and must be consistent with the [[Definition:Rate filing | rate filing]] approved by the relevant state [[Definition:Department of insurance | department of insurance]]; deviations require their own filings.<br /> <br /> 🔧 Maintaining an accurate, up-to-date rating manual is an operational imperative. Errors in the manual cascade into every quote the carrier issues, potentially creating [[Definition:Underpricing | underpriced]] segments that attract adverse selection or [[Definition:Overpricing | overpriced]] ones that repel good business. As carriers migrate from static PDF manuals to API-driven [[Definition:Rating engine | rating engines]], the underlying logic grows more complex — incorporating real-time data, [[Definition:Predictive analytics | predictive-analytics]] scores, and dynamic tier assignments — but the principle remains the same: every premium must be traceable to a documented, filed, and defensible methodology. For [[Definition:Insurance broker | brokers]] and auditors, the rating manual is the definitive reference for verifying that a quoted premium has been correctly calculated.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Rate filing]]<br /> * [[Definition:Insurance Services Office (ISO)]]<br /> * [[Definition:Experience rating]]<br /> * [[Definition:Pricing model]]<br /> * [[Definition:Classification code]]<br /> * [[Definition:Rating engine]]<br /> {{Div col end}}</div>
