<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📊 &#039;&#039;&#039;Activity-based costing&#039;&#039;&#039; is a cost-allocation methodology used by [[Definition:Insurance carrier | insurance carriers]] and [[Definition:Managing general agent (MGA) | MGAs]] to trace operational expenses to the specific activities — such as [[Definition:Underwriting | underwriting]], [[Definition:Claims handling | claims handling]], or [[Definition:Policy administration | policy administration]] — that actually drive those costs. Unlike traditional costing methods that spread overhead evenly across products or departments, activity-based costing identifies cost drivers at a granular level, enabling insurers to understand precisely how much it costs to issue a certain [[Definition:Insurance policy | policy]], process a particular [[Definition:Insurance claim | claim]] type, or service a given distribution channel.<br /> <br /> ⚙️ In practice, an insurer implementing this approach begins by mapping every significant activity in its value chain — from initial [[Definition:Risk assessment | risk assessment]] and [[Definition:Quote | quote]] generation to [[Definition:Loss adjustment | loss adjustment]] and [[Definition:Reinsurance | reinsurance]] recovery. Each activity is assigned a cost pool, and a measurable driver (such as the number of endorsements processed or the hours spent on [[Definition:Subrogation | subrogation]] reviews) links that pool to specific products or lines of business. When the model runs, leadership can see that, for instance, a [[Definition:Commercial lines | commercial lines]] portfolio with complex [[Definition:Endorsement | endorsements]] consumes far more underwriting resources per dollar of [[Definition:Gross written premium (GWP) | gross written premium]] than a standardized [[Definition:Personal lines | personal lines]] book. Many [[Definition:Insurtech | insurtech]] platforms now embed activity-based costing logic directly into their [[Definition:Policy administration system | policy administration systems]], automating the data capture that once required months of manual study.<br /> <br /> 💡 Accurate cost visibility is a competitive differentiator in an industry where [[Definition:Expense ratio | expense ratios]] directly affect [[Definition:Combined ratio | combined ratio]] performance and, ultimately, profitability. By revealing which products, channels, or customer segments are truly profitable after fully loaded costs, activity-based costing empowers executives to make sharper decisions about pricing adequacy, resource deployment, and strategic growth. Regulators and [[Definition:Rating agency | rating agencies]] also increasingly expect insurers to demonstrate disciplined expense management, making a robust costing framework not just a management tool but a governance asset.<br /> <br /> &#039;&#039;&#039;Related concepts:&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Expense ratio]]<br /> * [[Definition:Combined ratio]]<br /> * [[Definition:Underwriting expense]]<br /> * [[Definition:Loss ratio (L/R)]]<br /> * [[Definition:Policy administration system]]<br /> * [[Definition:Operating ratio]]<br /> {{Div col end}}</div>
