<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>📉 &#039;&#039;&#039;Expense ratio&#039;&#039;&#039; is a key profitability metric that measures an [[Definition:Insurance carrier | insurance carrier&#039;s]] operating and acquisition costs as a percentage of [[Definition:Net written premium | net written premium]] (or, in some formulations, [[Definition:Net earned premium | net earned premium]]). It captures every dollar spent on [[Definition:Commission | commissions]], [[Definition:Brokerage fee | brokerage]], salaries, technology, marketing, and general administration for each dollar of [[Definition:Premium | premium]] the company brings in — essentially quantifying how efficiently the insurer converts revenue into deployable underwriting capacity.<br /> <br /> 🧮 The calculation is straightforward: divide total [[Definition:Underwriting expense | underwriting expenses]] by net written or earned premium and multiply by 100. Analysts often decompose it further into a [[Definition:Loss adjustment expense (LAE) | loss-adjustment expense]] component (costs tied to investigating and settling [[Definition:Insurance claim | claims]]) and a pure operational component (everything else). When the expense ratio is combined with the [[Definition:Loss ratio (L/R) | loss ratio]], the result is the [[Definition:Combined ratio | combined ratio]] — the single most watched indicator of [[Definition:Underwriting | underwriting]] profitability. A combined ratio below 100 percent means the carrier is generating an [[Definition:Underwriting profit | underwriting profit]] before investment income is even considered.<br /> <br /> 💡 Carriers face persistent pressure to drive the expense ratio lower without sacrificing service quality or distribution reach. Legacy [[Definition:Policy administration system | policy administration systems]], manual workflows, and multi-layered distribution chains all inflate costs, which is precisely why [[Definition:Insurtech | insurtechs]] promoting [[Definition:Straight-through processing (STP) | straight-through processing]], [[Definition:Digital distribution | digital distribution]], and [[Definition:Automation | automation]] have attracted significant investor attention. Even a modest reduction — say, two points off a 32 percent expense ratio — flows directly to the bottom line across the entire [[Definition:Book of business | book of business]], making operational efficiency one of the most reliable levers for sustainable competitive advantage.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Combined ratio]]<br /> * [[Definition:Loss ratio (L/R)]]<br /> * [[Definition:Net earned premium]]<br /> * [[Definition:Underwriting profit]]<br /> * [[Definition:Commission]]<br /> * [[Definition:Operating leverage]]<br /> {{Div col end}}</div>
