<p><b>New page</b></p><div>đ˘ '''Insurance rating''' is the systematic process of applying [[Definition:Insurance rate | rates]], rating factors, and classification rules to a specific risk in order to calculate the [[Definition:Insurance premium | premium]] a [[Definition:Policyholder | policyholder]] will be charged. It bridges the gap between the generalized rate structures developed by [[Definition:Actuarial science | actuaries]] and the individual price assigned to a particular [[Definition:Insurance policy | policy]]. Rating takes into account variables such as the risk's [[Definition:Classification code | classification]], geographic location, [[Definition:Loss history | loss history]], size, and any applicable [[Definition:Insurance discount | credits or debits]], systematically combining them to arrive at a final premium.<br />
<br />
âď¸ In practice, rating can be performed manually by an [[Definition:Underwriting | underwriter]] but is increasingly executed by [[Definition:Rating engine | rating engines]]âsoftware platforms that automate the calculation based on predefined algorithms and rule sets. For personal lines, rating engines can generate a premium in seconds by pulling data from [[Definition:Insurance application | applications]], [[Definition:Motor vehicle report (MVR) | motor vehicle reports]], [[Definition:Credit-based insurance score | credit scores]], and property databases. In commercial lines, the process may involve multiple layers: a base rate from an [[Definition:Rating bureau | advisory organization]], an [[Definition:Experience modification factor | experience modification factor]], [[Definition:Schedule rating | schedule rating]] adjustments applied by the underwriter, and [[Definition:Package modification factor | package modification factors]] for multi-line accounts. [[Definition:Insurtech | Insurtech]] companies have pushed rating technology further, incorporating [[Definition:Machine learning | machine learning]] models that refine risk classifications and detect pricing signals invisible to traditional tables.<br />
<br />
đ Accurate, consistent rating is essential for both competitive positioning and [[Definition:Insurance regulation | regulatory compliance]]. Errors in the rating processâmisapplied classifications, incorrect territory codes, overlooked endorsementsâcan lead to premium leakage that silently erodes an insurer's margins, or to overcharges that trigger regulatory penalties and customer attrition. State regulators audit [[Definition:Insurance carrier | carriers]] and [[Definition:Managing general agent (MGA) | MGAs]] to verify that the rates being charged match those that were filed and approved. As the complexity of rating variables grows with the incorporation of [[Definition:Telematics | telematics]], [[Definition:Internet of things (IoT) | IoT]] data, and behavioral analytics, the governance frameworks around rating accuracy have become a critical area of operational focus.<br />
